  • AutoCompleteTextView with custom list: how to set up onClick Listeners and getting the selected item

    - by steff
    Hi everyone, I am working on an app which uses tags. Accessing those should be as simple as possible. Working with an AutoCompleteTextView seems appropriate to me. What I want: existing tags should be displayed in a selectable list with a CheckBox on each item's side existing tags should be displayed UPON FOCUS of AutoCompleteTextView (i.e. not after typing a letter) What I've done so far is storing tags in a dedicated sqlite3 table. Tags are queried resulting in a Cursor. The Cursor is passed to a SimpleCursorAdapter which looks like this: Cursor cursor = dbHelper.getAllTags(); startManagingCursor(cursor); String[] columns = new String[] { TagsDB._TAG}; int[] to = new int[] { R.id.tv_tags}; SimpleCursorAdapter cursAdapt = new SimpleCursorAdapter(this, R.layout.tags_row, cursor, columns, to); actv.setAdapter(cursAdapt); As you can see I created *tags_row.xml* which looks like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingLeft="4dip" android:paddingRight="4dip" android:orientation="horizontal"> <TextView android:id="@+id/tv_tags" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:textColor="#000" android:onClick="actv_item_click" /> <CheckBox android:id="@+id/cb_tags" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="actv_item_checked" /> </LinearLayout> It looks like this: So the results are displayed just as I'd want them to. But the TextView's onClick listener does not respond. And I don't have a clue on how to access the data once an item is (de-)selected. Behaviour of the list should be the following: tapping a CheckBox item should insert/append the corresponding tag into the AutoCompleteTextView (tags will be semicolon-seperated) tapping a TextView item should insert/apped the corresponding tag into the AutoCompleteTextView AND close the list. So please help me out. Thanks in advance, steff

  • View all ntext column text in SQL Server Management Studio for SQL CE database

    - by Dave
    I often want to do a "quick check" of the value of a large text column in SQL Server Management Studio (SSMS). The maximum number of characters that SSMS will let you view, in grid results mode, is 65535. (It is even less in text results mode.) Sometimes I need to see something beyond that range. Using SQL Server 2005 databases, I often used the trick of converting it to XML, because SSMS lets you view much larger amounts of text that way: SELECT CONVERT(xml, MyCol) FROM MyTable WHERE ... But now I am using SQL CE, and there is no Xml data type. There is still a "Maximum Characters Retreived XML" value under Options; I suppose this is useful when connecting to other data sources. I know I can just get the full value by running a little console app or something, but is there a way within SSMS to see the entire ntext column value? [Edit] OK, this didn't get much attention the first time around (18 views?!). It's not a huge concern, but maybe I'm just obsessed with it. There has to be some good way around this, doesn't there? So a modest bounty is active. What I am willing to accept as answers, in order from best-to-worst: A solution that works just as easy as the XML trick in SQL CE. That is, a single function (convert, cast, etc.) that does the job. A not-too-invasive way to hack SSMS to get it to display more text in the results. An equivalent SQL query (perhaps something that creatively uses SUBSTRING and generates multiple ad-hoc columns??) to see the results. The solution should work with nvarchar and ntext columns of any length in SQL CE from SSMS. Any ideas?

  • C# DataSet CheckBox Column With DevExpress DataGrid

    - by Goober
    Scenario I have a DevExpress DataGrid which is bound to a DataSet in C#. I want to populate each dataset row to contain a string in the first column and a checkbox in the second. My code below doesn't work quite how I want it to, and I'm not sure why..... The Code As you can see I've declared a dataset, but when I try and pass in a new checkbox object to the 2nd column it just displays the system name for the checkbox. DataSet prodTypeDS = new Dataset(); DataTable prodTypeDT = prodTypeDS.Tables.Add(); prodTypeDT.Columns.Add("MurexID", typeof(string)); prodTypeDT.Columns.Add("Haganise",typeof(CheckBox)); //WHY DOES THIS NOT WORK? //(Displays "System.Windows.Forms.CheckBox, CheckState: 0") //Instead of a checkbox. CheckBox c = new CheckBox(); prodTypeDS.Tables[0].Rows.Add("Test",c); //This doesn't work either.... prodTypeDS.Tables[0].Rows.Add("Test",c.CheckState); ......I hope this is just because it's a DevExpress datagrid....

  • WinForms ComboBox DropDown and Autocomplete window both appear

    - by Clyde
    I've got a combobox on a winforms app with this code: comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend; comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems; DataTable t = new DataTable(); t.Columns.Add("ID", typeof(int)); t.Columns.Add("Display", typeof(string)); for (int i = 1; i < 2000; i++) { t.Rows.Add(i, i.ToString("N0")); } comboBox1.DataSource = t; comboBox1.ValueMember = "ID"; comboBox1.DisplayMember = "Display"; I then follow these steps when the window opens: Click the combobox drop down button -- this displays the list of items and selects the text in the combobox Type '5', '1' ... i.e. I'm looking to use autocomplete to search for 515, 516, etc. You'll see that the autocomplete window now appears ON TOP of the drop down list. However if I mouse over, it's the obscured drop down window behind the autocomplete window that's receiving the mouse events, including the click. So I think I'm clicking on an autocomplete item but actually clicking on something totally random that I can't see. Is this a bug in the ComboBox? I'm using Windows 7 if that matters. Am I configuring the ComboBox wrong somehow? Note also that using the KEYBOARD uses the autocomplete drop down. So up/down arrow keys are using the front window, but the mouse is using the back window.

  • Manual (Dynamic) LINQ subquery using IN clause

    - by immortalali-msn-com
    Hi Everyone, I want to query the DB through LINQ writing manual SQL, my linq method is: var q = db.TableView.Where(sqlAfterWhere); returnValue = q.Count(); this method queries well if the value passed to variable "sqlAfterWhere" is: (this variable is String type) it.Name = 'xyz' but what if i want to use IN clause, using a sub query. (i need to use 'it' before every column name in the above query to work), i cant use 'it' before the sub query columns as its a separate query, so what should i do, if i dont use any thing, and use column names directly it gives error saying " could not be resolved" where is my column names with out 'it' at the begining. So the query not working is: (this is a string passed to the variable above): it.Name IN (SELECT Name FROM TableName WHERE Address LIKE '%SomeAddress%') the errors come out as: Name could not be resolved Address could not be resolved The exact error is: "'Name' could not be resolved in the current scope or context. Make sure that all referenced variables are in scope, that required schemas are loaded, and that namespaces are referenced correctly., near simple identifier, line 6, column 25." Same error for "Address as well if i use 'it.' before these columns it gives error as: "The element type 'Edm.Int32' and the CollectionType 'Transient.collection[Transient.rowtype(GroupID,Edm.Int32(Nullable=True,DefaultValue=))]' are not compatible. The IN expression only supports entity, primitive, and reference types. , near WHERE predicate, line 6, column 14." Thanks for the help

  • How to bind collection to WPF:DataGridComboBoxColumn

    - by everwicked
    Admittedly I am new to WPF but I have looked and looked and can't find a solution to this problem. I have a simple object like: class Item { .... public String Measure { get; set; } public String[] Measures {get; } } Which I am trying to bind to a DataGrid with two text columns and a combo box column. For the combo box column, propery Measure is the current selection and Measures the possible values. My XAML is: <DataGridComboBoxColumn Header="Measure" Width="Auto" SelectedItemBinding="{Binding Path=Measure}" ItemsSource="{Binding Path=Measures}"/> </DataGrid.Columns> </DataGrid> The text column are displayed just fine but the combobox is not - the values are not displayed at all. The binding error is : ¨System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Measures; DataItem=null; target element is 'DataGridComboBoxColumn' (HashCode=11497055); target property is 'ItemsSource' (type 'IEnumerable') How do I fix this??? Thanks

  • Mimicking the UltraGridColumnChooser's drag & drop ability

    - by Sören Kuklau
    (Infragistics 2008 Vol. 3, CLR 2.0) Infragistics's UltraGrid comes with a column chooser user control, which is simply a vertical arrangement of columns with checkboxes that toggle a column's hidden state. In addition, it allows you to pick a column and drag it directly to the grid so you don't have to manually position it afterwards. (This is particularly handy when you already have a lot of visible columns and have no clue where the new one ended up.) I'm building my own column chooser based on an UltraTree. Getting the checkboxes to behave the same wasn't an issue, but I haven't found a way to drag a column from the tree to the grid and have it accept it. In my tree, each UltraTreeNode has a Tag with the following struct: Private Structure DraggableGridColumn Public NodeKey As String Public NodeName As String Public ParentKey As String Public Column As UltraGridColumn End Structure I then have an event as follows: Private Sub columnsTree_SelectionDragStart(ByVal sender As Object, ByVal e As System.EventArgs) Handles columnsTree.SelectionDragStart If columnsTree.SelectedNodes.Count <> 1 Then Return End If If Not TypeOf columnsTree.SelectedNodes(0).Tag Is DraggableGridColumn Then Return End If Dim column As UltraGridColumn = CType(columnsTree.SelectedNodes(0).Tag, DraggableGridColumn).Column columnsTree.DoDragDrop(column, DragDropEffects.All) End Sub In the DoDragDrop call, neither column (of type UltraGridColumn) nor column.Header (of type ColumnHeader) get accepted by the grid. I assume I'm sending the wrong type, and/or that the grid expects a special struct with some additional information. Unfortunately, I've also failed to catch an event (both on the column chooser side as well as on the grid side) where Infragistics's normal column chooser does this properly; the normal drag & drop events never seem to fire.

    I have a css table setup like this: <div class='table'> <div> <span>name</span> <span>details</span> </div> </div> The css for the table is: .table{ display:table; width:100%; } .table div{ text-align:right; display:table-row; border-collapse: separate; border-spacing: 0px; } .table div span:first-child { text-align:right; } .table div span { vertical-align:top; text-align:left; display:table-cell; padding:2px 10px; } As it stands the two columns are split evenly between the space occupied by the width of the table. I'm trying to get the first column only to be as wide as is needed by the text occupying it's cells The table is an unknown width, as are the columns/cells.

  • wpf 4.0 datagrid template column two-way binding problem

    - by rouwlee
    Hello all! I'm using the datagrid from wpf 4.0. This has a TemplateColumn containing a checkbox. The IsChecked property of the checkbox is set via binding. The problem is that even if I specify the binding mode explicitly to be TwoWay, it works only in one direction. I have to mention that the same code works perfectly in .net 3.5 with the datagrid from the wpf toolkit. Please take a look at the .xaml and .cs contents. Thanks in advance, Roland <Window.Resources> <DataTemplate x:Key="IsSelectedColumnTemplate"> <CheckBox IsChecked="{Binding Path=IsSelected, Mode=TwoWay}" /> </DataTemplate> </Window.Resources> <Grid> <DataGrid x:Name="dataGrid" AutoGenerateColumns="false" CanUserAddRows="False" CanUserDeleteRows="False" HeadersVisibility="Column" ItemsSource="{Binding}" > <DataGrid.Columns> <DataGridTemplateColumn Header="Preselected" x:Name="myIsSelectedColumn" CellTemplate="{StaticResource IsSelectedColumnTemplate}" CanUserSort="True" SortMemberPath="Orientation" Width="Auto" /> </DataGrid.Columns> </DataGrid> </Grid> and the related .cs content: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); ObservableCollection<DataObject> DataSource = new ObservableCollection<DataObject>(); DataSource.Add(new DataObject()); dataGrid.ItemsSource = DataSource; } } public class DataObject : DependencyObject { public bool IsSelected { get { return (bool)GetValue(IsSelectedProperty); } set { SetValue(IsSelectedProperty, value); } } // Using a DependencyProperty as the backing store for IsSelected. This enables animation, styling, binding, etc... public static readonly DependencyProperty IsSelectedProperty = DependencyProperty.Register("IsSelected", typeof(bool), typeof(DataObject), new UIPropertyMetadata(false, OnIsSelectedChanged)); private static void OnIsSelectedChanged(DependencyObject obj, DependencyPropertyChangedEventArgs e) { // this part is not reached } }

  • JQGrid: Dropdown for selecting items from a foreign table - DataValueField vs DataTextField

    - by Herb Caudill
    Suppose Items and ItemTypes have numeric primary keys ItemID and ItemTypeID. Each Item is assigned an ItemType. I have a JQGrid to edit Items. When not in edit mode, I would like to see the name of the ItemType, not the ItemTypeID: TYPE | TITLE -----------+-------------------- Category A | Item 1 Category A | Item 2 Category B | Item 3 Category B | Item 4 In edit mode, I want to see a dropdown that displays the ItemType text, but that returns the ItemTypeID to the server. Here's what I have so far (using the ASP.NET wrapper for JQGrid): <trirand:jqgrid id="Grid1" runat="server" ... > <columns> <trirand:jqgridcolumn datafield="ItemID" editable="false" visible="false" width="50" primarykey="true" /> <trirand:jqgridcolumn datafield="ItemTypeID" editable="true" edittype="DropDown" editorcontrolid="ItemTypes" /> <trirand:jqgridcolumn datafield="Title" editable="true" sortable="true" /> ... </columns> </trirand:jqgrid> <asp:sqldatasource runat="server" id="ItemTypesDatasource" connectionstring="<%$ ConnectionStrings:Main %>" selectcommand="Select ItemTypeID,Title from ItemTypes order by Title" /> <asp:dropdownlist runat="server" id="ItemTypes" datasourceid="ItemTypesDatasource" datavaluefield="ItemTypeID" datatextfield="Title" /> The problem is that when not in edit mode, it displays the numeric ItemTypeID, rather than the text labels: TYPE | TITLE -----------+-------------------- 100123 | Item 1 100123 | Item 2 100124 | Item 3 100124 | Item 4 Is there any way to have JQGrid respect the distinction between DataValueField and DataTextField? (Either using the jQuery API or the ASP.NET plugin.)

  • Access to DataTemplate Control of WPF Toolkit DataGridCell at Runtime, How?

    - by LukePet
    I have a DataGrid defined with WPF Toolkit. The CellEditingTemplate of this DataGrid is associated at runtime with a custom function that build a FrameworkElementFactory element. Now I have to access to control that is inserted inside DataTemplate of CellEditingTempleta, but I do not know how to do. On web I found a useful ListView Helper... public static class ListViewHelper { public static FrameworkElement GetElementFromCellTemplate(ListView listView, Int32 column, Int32 row, String name) { if (row >= listView.Items.Count || row < 0) { throw new ArgumentOutOfRangeException("row"); } GridView gridView = listView.View as GridView; if (gridView == null) { return null; } if (column >= gridView.Columns.Count || column < 0) { throw new ArgumentOutOfRangeException("column"); } ListViewItem item = listView.ItemContainerGenerator.ContainerFromItem(listView.Items[row]) as ListViewItem; if (item != null) { GridViewRowPresenter rowPresenter = GetFrameworkElementByName<GridViewRowPresenter>(item); if (rowPresenter != null) { ContentPresenter templatedParent = VisualTreeHelper.GetChild(rowPresenter, column) as ContentPresenter; DataTemplate dataTemplate = gridView.Columns[column].CellTemplate; if (dataTemplate != null && templatedParent != null) { return dataTemplate.FindName(name, templatedParent) as FrameworkElement; } } } return null; } private static T GetFrameworkElementByName<T>(FrameworkElement referenceElement) where T : FrameworkElement { FrameworkElement child = null; for (Int32 i = 0; i < VisualTreeHelper.GetChildrenCount(referenceElement); i++) { child = VisualTreeHelper.GetChild(referenceElement, i) as FrameworkElement; System.Diagnostics.Debug.WriteLine(child); if (child != null && child.GetType() == typeof(T)) { break; } else if (child != null) { child = GetFrameworkElementByName<T>(child); if (child != null && child.GetType() == typeof(T)) { break; } } } return child as T; } } this code work with the ListView object but not with the DataGrid object. How can use something like this in DataGrid?

  • C# Convert Excel Range to Dataset or Datatable, etc.

    - by htbrady
    I have an Excel spreadsheet that will sit out on a network share drive. It needs to be accessed by my Winforms C# 3.0 application (many users could be using the app and hitting this spreadsheet at the same time). There is a lot of data on one worksheet. This data is broken out into areas that I have named as ranges. I need to be able to access these ranges individually, return each range as a dataset, and then bind it to a grid. I have found examples that use OLE and have got these to work. However, I have seen some warnings about using this method, plus at work we have been using Microsoft.Office.Interop.Excel as the standard thus far. I don't really want to stray from this unless I have to. Our users will be using Office 2003 on up as far as I know. I can get the range I need with the following code: MyDataRange = (Microsoft.Office.Interop.Excel.Range)MyWorkSheet.get_Range("MyExcelRange", Type.Missing); The OLE way was nice as it would take my first row and turn those into columns. My ranges (12 total) are for the most part different from each other in number of columns. Didn't know if this info would affect any recommendations. Is there any way to use Interop and get the returned range back into a dataset? Thanks for your help.

  • Google Apps Script - Sending Google Spreadsheet Row to Email

    - by AME
    Hi I am trying to write a script using Google Apps Script (Javascript) for a Google spreadsheet. I am trying to do the same thing that is shown in this tutorial [http://www.google.com/google-d-s/scripts/sending_emails.html][1], but each row in my spreadsheet has 24 columns. I would like to send out the contents of each row as an email. Here is the code as I am trying to use: function sendEmails() { var sheet = SpreadsheetApp.getActiveSheet(); var dataRange = sheet.getRange("A2:X31") // Fetch values for each row in the Range. var data = dataRange.getValues(); for (i in data) { var row = data[i]; var i = i + 1; var emailAddress = row[0]; // First column var message = row[1]; // Second column var subject = "Sending emails from a Spreadsheet"; MailApp.sendEmail(emailAddress, subject, message); } }? The result is an email with the contents in the "B" column only. Can someone help me change this code to get all of the contents in each row (columns A-X). Thanks,

    Hi Everyone, I have a small question which should be very easy for the jquery experts out there. I am trying to follow http://aspdotnetcodebook.blogspot.com/2010/01/page-languagec-autoeventwireuptrue.html to be able to perform an action on gridview row double click. I can redirect to another page fine (as shown in the example) but I cannot cause the $(this).find("a").click(); to fire.

  • How to HitTest in a WPF Grid Panel to find column index.

    - by John
    Hi. We need to create a "timeline" feature where a user is allowed to drag and draw "time spans" into a WPF grid (we thought this better than a Canvas since it has resizing capabilities). Each span spans multiple columns, but only one row. We utilize the PreviewMouseDown/Up/Move events to see when the user clicks, drags, and releases the mouse. On the "Down" we create a new rectangle and on the "Move" we resize the rectangle, settings its ColumnSpan property to the correct value every time the mouse enteres the next column. At this point the grid has 48 1-star-sized columns. How do we find out which column the user has clicked on? Right now we are unable to find the column using the VisualTreeHelper.HitTest function. We would like to position the rectangle correctly via Grid.SetColumn(rect, X) and then resize it as needed using Grid.SetColumnSpan(rect, Y) Has anyone done something like this before and can help us? Or, is there a better way to draw what we need? Thanks.

  • How to avoid circular relationship in SQL-Server?

    - by Shimmy
    I am creating a self-related table: Table Item columns: ItemId int - PK; Amount money - not null; Price money - a computed column using a UDF that retrieves value according to the items ancestors' Amount. ParentItemId int - nullable, reference to another ItemId in this table. I need to avoid a loop, meaning, a sibling cannot become an ancestor of his ancestors, meaning, if ItemId=2 ParentItemId = 1, then ItemId 1 ParentItemId = 2 shouldn't be allowed. I don't know what should be the best practice in this situation. I think I should add a CK that gets a Scalar value from a UDF or whatever else. EDIT: Another option is to create an INSTEAD OF trigger and put in 1 transaction the update of the ParentItemId field and selecting the Price field from the @@RowIdentity, if it fails cancel transaction, but I would prefer a UDF validating. Any ideas are sincerely welcomed.

  • wpf datagrid current item binding

    - by tk
    I want to bind a content of Label to the selected item of a datagrid. I thought the 'current item' binding expression would work, but it is not. My xaml code and code-behind c# is like below. <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="512" Width="847"> <DockPanel LastChildFill="True"> <Label Content="{Binding Data/colA}" DockPanel.Dock="Top" Height="30"/> <DataGrid ItemsSource="{Binding Data}"></DataGrid> </DockPanel> </Window> namespace WpfApplication2 { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); this.DataContext = new MyData(); } } public class MyData { DataTable data; public MyData() { data = new DataTable(); data.Columns.Add("colA"); data.Columns.Add("colB"); data.Rows.Add("aa", 1); data.Rows.Add("bb", 2); } public DataTable Data { get { return data; } } } } The label shows the first item of the DataTable, and does not change when i select other items on the datagrid. It seems the current item of dataview does not change. What should i do to bind it to the current selected item of datagrid?

  • How to get rank from full-text search query with Linq to SQL?

    - by Stephen Jennings
    I am using Linq to SQL to call a stored procedure which runs a full-text search and returns the rank plus a few specific columns from the table Article. The rank column is the rank returned from the SQL function FREETEXTTABLE(). I've added this sproc to the data model designer with return type Article. This is working to get the columns I need; however, it discards the ranking of each search result. I'd like to get this information so I can display it to the user. So far, I've tried creating a new class RankedArticle which inherits from Article and adds the column Rank, then changing the return type of my sproc mapping to RankedArticle. When I try this, an InvalidOperationException gets thrown: Data member 'Int32 ArticleID' of type 'Heap.Models.Article' is not part of the mapping for type 'RankedArticle'. Is the member above the root of an inheritance hierarchy? I can't seem to find any other questions or Google results from people trying to get the rank column, so I'm probably missing something obvious here.

  • Understanding ItemsSource and DataContext in a DataGrid

    - by Ben McCormack
    I'm trying to understand how the ItemsSource and DataContext properties work in a Silverlight Toolkit DataGrid. I'm currently working with dummy data and trying to get the data in the DataGrid to update when the value of a combo box changes. My MainPage.xaml.vb file currently looks like this: Partial Public Class MainPage Inherits UserControl Private IssueSummaryList As List(Of IssueSummary) Public Sub New() GetDummyIssueSummary("Day") InitializeComponent() dgIssueSummary.ItemsSource = IssueSummaryList 'dgIssueSummary.DataContext = IssueSummaryList ' End Sub Private Sub GetDummyIssueSummary(ByVal timeInterval As String) Dim lst As New List(Of IssueSummary)() 'Generate dummy data for lst ' IssueSummaryList = lst End Sub Private Sub ComboBox_SelectionChanged(ByVal sender As System.Object, ByVal e As System.Windows.Controls.SelectionChangedEventArgs) Dim cboBox As ComboBox = CType(sender, ComboBox) Dim cboBoxItem As ComboBoxItem = CType(cboBox.SelectedValue, ComboBoxItem) GetDummyIssueSummary(cboBoxItem.Content.ToString()) End Sub End Class My XAML currently looks this for the DataGrid: <sdk:DataGrid x:Name="dgIssueSummary" AutoGenerateColumns="False" > <sdk:DataGrid.Columns> <sdk:DataGridTextColumn Binding="{Binding ProblemType}" Header="Problem Type"/> <sdk:DataGridTextColumn Binding="{Binding Count}" Header="Count"/> </sdk:DataGrid.Columns> </sdk:DataGrid> The problem is that if I set the value of the ItemsSource property of the data grid equal to IssueSummaryList, it will display the data when it loads, but it won't update when the underlying IssueSummaryList collection changes. If I set the DataContext of the grid to be IssueSummaryList, no data will be displayed when it renders. I must not understand how ItemsSource and DataContext are supposed to function, because I expect one of those properties to "just work" when I assign a List object to them. What do I need to understand and change in my code so that as data changes in the List, the data in the grid is updated?

  • Laravel - Paginate and get()

    - by Bajongskie
    With the code below, what I wanted was paginate the query I created. But, when I try to add paginate after get, it throws an error. I wanted to remain get since I want to limit to columns that was set on $fields. What would should be the better idea to paginate this thing? or what's a good substitute for get and limit the columns?

'%') ->join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id') ->get($this->fields); } else { $phones = Phone::join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id') ->get($this->fields); } return View::make('phones.index')->with('phones', $phones); } }

  • Android layout issue - relative widths

    - by cdonner
    I am trying to assign relative widths to columns in a ListView that is in a TabHost, using layout_weight as suggested here: <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TableLayout android:id="@+id/triplist" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingTop="4px"> <TableRow> <ListView android:id="@+id/triplistview" android:layout_width="fill_parent" android:layout_height="wrap_content"/> </TableRow> <TableRow> <Button android:id="@+id/newtripbutton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Add Trip"/> </TableRow> [other tabs ...] My row definition has 4 columns that I would like to size as follows: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:weightSum="1.0" android:padding="4px"> <TextView android:id="@+id/rowtripdate" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content" android:inputType="date"/> <TextView android:id="@+id/rowodostart" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content"/> <TextView android:id="@+id/rowodoend" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content"/> <TextView android:id="@+id/rowcomment" android:layout_weight=".4" android:layout_width="0dip" android:layout_height="wrap_content"> Unfortunately, it seems to want to fit all the column into the space that the button occupies, as opposed to the width of the screen. Or maybe there is another constraint that I do not understand. I'd appreciate your help.

  • Dialogs (Real ones)

    - by Richard W
    Having tried a number of different solutions I keep coming back to this. I need a Window.ShowDialog, using the ViewModelLocator class as a factory via a UnityContainer. Basically I have a View(and ViewModel) which on a button press on the the view needs to create a dialog (taking a couple of parameters in its constructor) that will process some logic and eventally return a result to the caller (along with the results of all the logic it computed). Maybe I'm wrong for stilll looking at this from a Windows Forms perspective, but I know exactly what I want to do and I want to ideally do it using WPF and MVVM. I'm trying to make this work for a project, and ultimately don't want to have to go back to vanilla WPF in order to make it work.

  • Select the latest record for each category linked available on an object

    - by Simpleton
    I have a tblMachineReports with the columns: Status(varchar),LogDate(datetime),Category(varchar), and MachineID(int). I want to retrieve the latest status update from each category for every machine, so in effect getting a snapshot of the latest statuses of all the machines unique to their MachineID. The table data would look like Category - Status - MachineID - LogDate cata - status1 - 001 - date1 cata - status2 - 002 - date2 catb - status3 - 001 - date2 catc - status2 - 002 - date4 cata - status3 - 001 - date5 catc - status1 - 001 - date6 catb - status2 - 001 - date7 cata - status2 - 002 - date8 catb - status2 - 002 - date9 catc - status2 - 001 - date10 Restated, I have multiple machines reporting on multiple statuses in this tblMachineReports. All the rows are created through inserts, so their will obviously be duplicate entries for machines as new statuses come in. None of the columns can be predicted, so I can't do any ='some hard coded string' comparisons in any part of the select statement. For the sample table I provided, the desired results would look like: Category - Status - MachineID - LogDate catc - status2 - 002 - date4 cata - status3 - 001 - date5 catb - status2 - 001 - date7 cata - status2 - 002 - date8 catb - status2 - 002 - date9 catc - status2 - 001 - date10 What would the select statement look like to achieve this, getting the latest status for each category on each machine, using MS SQL Server 2008? I have tried different combinations of subqueries combined with aggregate MAX(LogDates)'s, along with joins, group bys, distincts, and what-not, but have yet to find a working solution.

  • Gridview sorting: SortDirection always Ascending

    - by Julien N
    Hi ! I have a gridview and I need to sort its elements when the user clicks on the header. Its datasource is a List object. The aspx is defined this way : <asp:GridView ID="grdHeader" AllowSorting="true" AllowPaging="false" AutoGenerateColumns="false" Width="780" runat="server" OnSorting="grdHeader_OnSorting" EnableViewState="true"> <Columns> <asp:BoundField DataField="Entitycode" HeaderText="Entity" SortExpression="Entitycode" /> <asp:BoundField DataField="Statusname" HeaderText="Status" SortExpression="Statusname" /> <asp:BoundField DataField="Username" HeaderText="User" SortExpression="Username" /> </Columns> </asp:GridView> The code behind is defined this way : First load : protected void btnSearch_Click(object sender, EventArgs e) { List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection(); this.grdHeader.DataSource = items; this.grdHeader.DataBind(); } when the user clicks on headers : protected void grdHeader_OnSorting(object sender, GridViewSortEventArgs e) { List<V_ReportPeriodStatusEntity> items = GetPeriodStatusesForScreenSelection(); items.Sort(new Helpers.GenericComparer<V_ReportPeriodStatusEntity>(e.SortExpression, e.SortDirection)); grdHeader.DataSource = items; grdHeader.DataBind(); } My problem is that e.SortDirection is always set to Ascending. I have webpage with a similar code and it works well, e.SortDirection alternates between Ascending and Descending. What did I do wrong ?
