  • Acrobat Reader ActiveX in WebBrowser stealing focus [C#]

    - by Maciej
    I'm using webBrowser.Navigate(url) control to display page. I noticed this action steals focus from current control (grid) and than I have problem to focus grid back (tired myGrid.Focus, .Select etc...) This is really annoying behaviour of browser... Does anyone knows how to prevent focus stealing by Browser or (if not) hot to force to focus control back ? EDIT: I've also tried webBrowser.DocumentCompleted event to focus back to grid EDIT 2 Good case to test this is openning PDF files webBrowser.Navigate(@"C:\TEMP\test.pdf") I believe this is ActiveX issue. On first glance it looks that this is not problem with focusing control but loosing entire Form focus... EDIT 3 I tried another approach: Form keyPress event: I thought I can capture form's keyPress and move focus from WebBrowser / AdobeReader ActiveX to my control. But surprisingly event is not fired! Looks Reader taken all control and there is no way to do anything programically until you do mouse click on (at least) form's caption Any advice (s) ?

  • Telerik RadGrid doesn't display on first Page_Load but does on postback

    - by Mark
    I have a page with a drop-down. Based on the selection in the drop-down, data gets loaded and populates a RadGrid. I am using a custom user control for the EditTemplate, so I can't use radGrid.DataBind(). Instead, I have to use radGrid.MasterTableView.Rebind() in association with a NeedDataSource event handler. My problem is that when I load the page initially, I populate the drop-down and automatically select a value (first item in the list) which triggers the databinding on the RadGrid. I can step through the code in debug mode and see that the grid is being populated with data, but when the page displays, it doesn't get rendered. When I then manually choose an item from the drop-down, which triggers the same grid databinding code, it displays properly the second time. How do I get it to display the grid the first time the page loads?

  • WPF Custom Buttons below ListBox Items

    - by Ryan
    WPF Experts - I am trying to add buttons below my custom listbox and also have the scroll bar go to the bottom of the control. Only the items should move and not the buttons. I was hoping for some guidance on the best way to achieve this. I was thinking the ItemsPanelTemplate needed to be modified but was not certain. Thanks My code is below <!-- List Item Selected --> <LinearGradientBrush x:Key="GotFocusStyle" EndPoint="0.5,1" StartPoint="0.5,0"> <LinearGradientBrush.GradientStops> <GradientStop Color="Black" Offset="0.501"/> <GradientStop Color="#FF091F34"/> <GradientStop Color="#FF002F5C" Offset="0.5"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> <!-- List Item Hover --> <LinearGradientBrush x:Key="MouseOverFocusStyle" StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Color="#FF013B73" Offset="0.501"/> <GradientStop Color="#FF091F34"/> <GradientStop Color="#FF014A8F" Offset="0.5"/> <GradientStop Color="#FF003363" Offset="1"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> <!-- List Item Selected --> <LinearGradientBrush x:Key="LostFocusStyle" EndPoint="0.5,1" StartPoint="0.5,0"> <LinearGradientBrush.RelativeTransform> <TransformGroup> <ScaleTransform CenterX="0.5" CenterY="0.5"/> <SkewTransform CenterX="0.5" CenterY="0.5"/> <RotateTransform CenterX="0.5" CenterY="0.5"/> <TranslateTransform/> </TransformGroup> </LinearGradientBrush.RelativeTransform> <GradientStop Color="#FF091F34" Offset="1"/> <GradientStop Color="#FF002F5C" Offset="0.4"/> </LinearGradientBrush> <!-- List Item Highlight --> <SolidColorBrush x:Key="ListItemHighlight" Color="#FFE38E27" /> <!-- List Item UnHighlight --> <SolidColorBrush x:Key="ListItemUnHighlight" Color="#FF6FB8FD" /> <Style TargetType="ListBoxItem"> <EventSetter Event="GotFocus" Handler="ListItem_GotFocus"></EventSetter> <EventSetter Event="LostFocus" Handler="ListItem_LostFocus"></EventSetter> </Style> <DataTemplate x:Key="CustomListData" DataType="{x:Type ListBoxItem}"> <Border BorderBrush="Black" BorderThickness="1" Margin="-2,0,0,-1"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListBoxItem}}, Path=ActualWidth}" /> </Grid.ColumnDefinitions> <Label VerticalContentAlignment="Center" BorderThickness="0" BorderBrush="Transparent" Foreground="{StaticResource ListItemUnHighlight}" FontSize="24" Tag="{Binding .}" Grid.Column="0" MinHeight="55" Cursor="Hand" FontFamily="Arial" FocusVisualStyle="{x:Null}" KeyboardNavigation.TabNavigation="None" Background="{StaticResource LostFocusStyle}" MouseMove="ListItem_MouseOver" > <Label.ContextMenu> <ContextMenu Name="editMenu"> <MenuItem Header="Edit"/> </ContextMenu> </Label.ContextMenu> <TextBlock Text="{Binding .}" Margin="15,0,40,0" TextWrapping="Wrap"></TextBlock> </Label> <Image Tag="{Binding .}" Source="{Binding}" Margin="260,0,0,0" Grid.Column="1" Stretch="None" Width="16" Height="22" HorizontalAlignment="Center" VerticalAlignment="Center" /> </Grid> </Border> </DataTemplate> </Window.Resources> <Window.DataContext> <ObjectDataProvider ObjectType="{x:Type local:ImageLoader}" MethodName="LoadImages" /> </Window.DataContext> <ListBox ItemsSource="{Binding}" Width="320" Background="#FF021422" BorderBrush="#FF1C4B79" > <ListBox.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}">Transparent</SolidColorBrush> <Style TargetType="{x:Type ListBox}"> <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Disabled" /> <Setter Property="ItemTemplate" Value="{StaticResource CustomListData }" /> </Style> </ListBox.Resources> </ListBox>

  • WPF DataGrid : CanContentScroll property causing odd behavior

    - by Sonic Soul
    i have a solution where i generate a DataGrid (or multiple instances) based on user criteria.. each grid keeps receiving data as it comes in via ObservableCollection the problem i had, was that the scroll acted weird. It was choppy, and scrollbar would resize it self while scrolling. than i found.. CanContentScroll property! It completely fixes the weird scrolling behavior bringing me temporary bliss and happiness. however, it causes 2 unfortunate side effects. whenever i re-create grid instances and bind them to my observable collection, it freezes my entire window for 5 seconds. when my grid grows to a big size, this delay can last for 30 seconds. when i call TradeGrid.ScrollIntoView(TradeGrid.Items(TradeGrid.Items.Count - 1)) to scroll to the bottom, it jumps to bottom and than back to the top. is there another way to achieve smooth scrolling perhaps?

  • Can I prevent window.onbeforeunload from being called when doing an AJAX call

    - by Paul
    I have an AJAX-based grid control. We hook into the window.onbeforeunload event to check if they have unsaved data and if so present them with a message "Are you sure you want to navigate away...you have unsaved data...". All this is good. But AJAX calls also trigger window.onbeforeunload and so if the grid has unsaved data and we make an AJAX call (such as to delete a row in another grid) the user gets the "Are you sure you want to navigate away...you have unsaved data..." message which is not good. Is it possible to suppress the onbeforeunload event for AJAX calls? Or is it possible to detect that a call is an AJAX call? Otherwise we'll have to get hacking! Thanks

  • ASP.Net GridView Sorting

    - by Ali Shafai
    I have a grid view with AllowSorting set to true. I get an event onsorting when a sortable header is clicked on. the handler has a parameter "GridViewSortEventArgs e" which has a SortDirection property on it. regardless of how many times you click on the same heading, the SortDirection is always Ascending. I think I'm missing something, like a way to tell the grid "now you are sorted based on column one and in ascending order", so that next time the grid sees a click on the "column one" heading, it decides to go descending. any help appreciated. Cheers, Ali

  • How to change the datasource on a YUI datagrid after creation

    - by Simon
    I am using the Yahoo DataTable for which the API is here. I am having difficulty changing the data once I have rendered the grid once. I am using jQuery to get data via AJAX, or from a client side data island and need to put this back into the grid. There is no setDataSource method in the DataTable API, and changing 'dataSource.liveData' does not update the grid. // does not work dataTable.dataSource.liveData = [ {name:"cat"}, {name:"dog"}, {name:"mouse"}; The example I am basing my code on is the basic LocalDataSource example. How can I update the data source without having to completely recreate the table. I do NOT want to use the YUI datasources that make Async calls. I need to know how I can do this 'manually'.

  • WPF drop shadow

    - by Petezah
    Currently I'm making something in WPF that has a border that contains a grid and other controls. The problem I'm facing is that whenever I set the Border.Effect property to a drop shadow effect every control contained in the border now has a drop shadow. Is there a way to set the shadow just to the border and not every control contained in the border? Here is a short example of my code: <Grid> <Border Margin="68,67,60,67" BorderBrush="Black" BorderThickness="1" CornerRadius="10"> <Border.Effect> <DropShadowEffect/> </Border.Effect> <Rectangle Fill="White" Stroke="Black" Margin="37,89,118,98" /> </Border> </Grid>

  • CSS Frameworks like 960 and Blueprint?

    - by Dean J
    This is at the framework level, not dealing directly with CSS, so posting to SO. I just learned about the existence of CSS frameworks. 960 Grid System seems pretty awesome, then I found Blueprint, which seems to do the same thing and more. Is there a better word than "framework" to categorize this? Are there any other products in this category? In response to one of the comments http://stackoverflow.com/questions/1483565/link-to-a-site-designed-using-a-css-framework-blueprint-960-etc, "how many example frameworks do you want? he just listed two of them.", I'd love to have more than two examples, unless those are the only two in the running. Blueprint, which is "the original CSS framework" 960 Grid System, which is a tool to have a grid underlying your screen. YUI 2: Grids, similar to 960? The rest of YUI is more similar to JQuery?

  • Grouping problem with postback in SPGridview

    - by Abhishek Rao
    I have a SPGridView with a custom CheckBox Template in it. To access the value of the checkbox I have created the SPGridView in Page_Init method. It was working fine. I also have grouping in the grid. It was working fine till I made any postback in the page. To overcome that I created my own custom GridView and overrided the LoadControlState event. Now the problem is when I use this Custom Grid in my page the LoadControlState event occurs after the Init event and hence the grid doesnt render on the page. When i keep it in Page_Load it works fine but my custom checkbox template creates a problem then. How do I get both the custom Checkbox Template and grouping with postback in the SPGridview working properly??? Please help as this is really getting me stuck.........

  • Combine master-detail databinding

    - by clawson
    I have created data sources from my objects in my project, some of which have other objects as members. When I want to bind a some objects to a data grid I would like to display some of the values from the member objects in the data grid as well but the examples I have come across seem to use an entire other datagrid or controls to display these member object values. How can I combine these values into one data grid? (Preferably without creating a wrapping class) Can I achieve this with LINQ somehow? Your help is greatly appreciated. Thanks P.S. C# or VB examples will do.

  • XPath to find ancestor node containing CSS class

    - by Juan Mendes
    I am writing some Selenium tests and I need to be able to find an ancestor of a WebElement that I have already found. This is what I'm trying but is returning no results // checkbox is also a WebElement WebElement container = checkbox.findElement(By.xpath( "current()/ancestor-or-self::div[contains(@class, 'x-grid-view')]") ); The image below shows the div that I have selected highlighted in dark blue and the one I want to find with an arrow pointing at it. UPDATE Tried prestomanifesto's suggestion and got the following error [cucumber] org.openqa.selenium.InvalidSelectorException: The given selector ./ancestor::div[contains(@class, 'x-grid-view']) is either invalid or does not result in a WebElement. The following error occurred: [cucumber] [InvalidSelectorError] Unable to locate an element with the xpath expression ./ancestor::div[contains(@class, 'x-grid-view']) because of the following error: [cucumber] [Exception...

  • WCF Paged Results & Data Export

    - by Ben
    I've walked into a project that is using a WCF service for the data tier. Currently, when data is needed for a grid, all rows are returned and the results are bound to a grid and the dataset is stuffed into a session variable for paging/sorting/rebinding. We've already hit a max message size problem, so I'm thinking it's time to convert from fetch and cache to fetch only the current page. Face value this seems easy enough, but there's a small catch. The user is allowed to export the entire result set at any point. This means that for grid viewing purposes fetching the current page is fine, but when they want to do an export, I still need to make a call for all data. This puts me back into the max message size issue. What is the recommended approach for this type of setup? We are currently using the wsHttpBinding... Thanks for any assistance.

  • So how I can control the page contents loading sequence in dojo

    - by David Zhao
    Hi there, I'm using dojo for our UI's, and would like to load certain part of page contents in sequence. For example, for a certain stock, I'd like to load stock general information, such as ticker, company name, key stats, etc. and a grid with the last 30 days open/close prices. Different contents will be fetched from the server separately. Now, I'd like first load the grid so the user can have something to look at, then, say, start loading of key stats which is a large data set takes longer time to load. How do I do this. I tried: dojo.addOnLoad(function() { startGrid(); //mock grid startup function which works fine getKeyStats(); //mock key stat getter function also works fine }); But dojo is loading getKeyStats(), then startGrid() here for some reason, and sequence doesn't seem be matter here. So how I can control the loading sequence at will? Thanks in advance! David

  • Text orientation

    - by Psytronic
    Hi Guys I know you can do this to get vertical text in a tab header: <Window x:Class="Abodemploy.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" <Grid <TabControl Margin="0" Name="tabControl1" FlowDirection="LeftToRight" TabStripPlacement="Left" <TabItem <TabItem.Header <StackPanel Orientation="Horizontal" <TextBlockHomes</TextBlock </StackPanel </TabItem.Header <TabItem.LayoutTransform <TransformGroup <RotateTransform Angle="90" / </TransformGroup </TabItem.LayoutTransform <Grid / </TabItem </TabControl </Grid </Window However the text letters are sideways. What I'd like (if possible) is for the letter orientation to be correct (ie upwards), but the text flow downwards, is this possible, or am I just dreaming the impossible dream? Thanks Psy

  • WPF DataGrid button style

    - by imekon
    If I have a DataGrid in a XAML form, and add the following style: <Style TargetType="Button"> <Setter Property="Margin" Value="2"/> </Style> The data grid locks up the application. I found if I put the style into a resource block that isn't seen by any data grid, then it seems to be happy. However, if I want to have the style above applied to all buttons on my window, I have to put it in various resource blocks that cannot be seen by the data grid. Is there any way to avoid this?

  • Splitting up/merging windows in WPF

    - by drasto
    I'm new to WPF but I need to implement following functionality: I have a window that contains one Grid (might be changed to stack panel or something else). In that Grid I have 2 columns, each of them contains another Grid. Lets call them gridFirst and gridSecond. There is also GridSplitter in first column allowing to resize the columns. I want to provide a button that will allow to separate gridFirst from this window and display it "as it is" in another window. How do I do that? It would be nice if the new window had a same menu as the original window without me having to copy-paste (that not a good coding practise) all its code to the new window. Thanks for answers

  • Using Office 2010 web apps with ASP.NET

    - by Martin de Ruiter
    Would it be possible to use the Office 2010 web apps with an ASP.NET application? For example: - For each user of my ASP.NET application there is a folder with Word documents on my server - The ASP.NET application displays the available documents in a grid to the user - When clicking on one of the documents in the grid, the Word document is loaded in an IFrame which contains the Office 2010 web apps Word interface and editing of the document can take place - After editing, the document can be saved to the server, and the ASP.NET grid displays an updated status Would such a scenario be possible? And what do you need, e.g. Sharepoint, Office 2010 licenses?

  • Buttons in the corners?

    - by Rick Ratayczak
    I'd like to have 4 buttons one in each corner of a window. But I want the stuff in the grid/window to be "behind" the buttons, as if they float on top. In html you would use the zOrder and absolute positioning. <Grid x:Name="ButtonRoot"> <Button Name="bTopLeft" VerticalAlignment="Top" HorizontalAlignment="Left" /> <Button Name="bTopRight" VerticalAlignment="Top" HorizontalAlignment="Right" /> <Button Name="bBottomLeft" VerticalAlignment="Bottom" HorizontalAlignment="Left" /> <Button Name="bBottomRight" VerticalAlignment="Bottom" HorizontalAlignment="Right" /> <!-- Other junk here --> </Grid> The problem is, the buttons will not be "over" things, as the things will "wrap" around the buttons. How do I achieve this effect?

  • How do I find hash value of a 3D vector ?

    - by brainydexter
    I am trying to perform broad-phase collision detection with a fixed-grid size approach. Thus, for each entity's position: (x,y,z) (each of type float), I need to find which cell does the entity lie in. I then intend to store all the cells in a hash-table and then iterate through to report (if any) collisions. So, here is what I am doing: Grid-cell's position: (int type) (Gx, Gy, Gz) = (x / M, y / M, z / M) where M is the size of the grid. Once, I have a cell, I'd like to add it to a hash-table with its key being a unique hash based on (Gx, Gy, Gz) and the value being the cell itself. Now, I cannot think of a good hash function and I need some help with that. Can someone please suggest me a good hash function? Thanks
