    - by user2978474
    I have question about my problem. Thru manustrip in form1 i have made new form2 when i click on a right option.

  • DataGridView with row-specific DataGridViewComboBoxColumn contents

    - by XXXXX
    So I have something like the following data structure (constructors omitted) class Child { public string Name { get; set; } public int Age { get; set; } } class Parent { public string Name { get; set; } public List <Child> Children { get; private set; } // never null; list never empty public Child FavoriteChild { get; set; } // never null; always a reference to a Child in Children } List < Parent > Parents; What I want to do is show a DataGridView where each row is a Parent from Parent list. Each row should have two columns: a text box showing the parent's name and a DataGridViewComboBoxColumn containing that parent's children, from which the user can select the parent's favorite child. I suppose I could do the whole thing manually, but I'd like to do all this with more-or-less standard Data Binding. It's easy enough to bind the DataGridView to the list of parents, and easy enough to bind the selected child to the FavoriteChild property. The part that's giving me difficulty is that it looks like the Combo Box column wants to bind to one data source for all the combo-box's contents on all rows. I'd like each instance of the combo box to bind to the list of each parent's children. I'm fairly new to C#/Windows Forms, so I may well be missing something obvious. Or it could be that "you can't get there from here." It's not too tough to make a separate list of all the children and filter it by parent; I'm looking into that possibility right now. Is this feasible, or is there a better way?

  • Row Prefix - ItemsControl with UniformGrid

    - by tenfour
    I am using an ItemsControl to display a List<byte> in hex. The ItemsPanelTemplate is a UniformGrid with a fixed number of columns: <ItemsControl HorizontalAlignment="Left" VerticalAlignment="Top" ItemsSource="{Binding}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <UniformGrid Columns="16"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding StringFormat='\{0:X2\}'}" Margin="5,5,5,0"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I'd like to prefix each row with an 'Address' column, just like you'd see with the Notepad++ 'HEX-Editor' plugin. That is, since I have 16 columns, each row should be prefixed something like this: 0000 [00 01 02 .... 0F] 0010 [10 11 12 .... 1F] 0020 [20 21 22 .... 2F] ... Any suggestions?

  • jQuery adding a row to a table with click() handler for tr

    - by Dave
    I'm having an issue with a control I'm building that contains a table where the body is scrollable. The rows have a click() function handler established like: /** * This function is called when the user clicks the mouse on a row in * our scrolling table. */ $('.innerTable tr').click (function (e) { // // Only react to the click if the mouse was clicked in the DIV or // the TD. // if (event.target.nodeName == 'DIV' || event.target.nodeName == 'TD' ) { // // If the user wasn't holding down the control key, then deselect // any previously selected columns. // if (e.ctrlKey == false) { $('.innerTable tr').removeClass ('selected'); } // // Toggle the selected state of the row that was clicked. // $(this).toggleClass ('selected'); } }); There is a button that adds rows to the table like: $('#innerTable > tbody:last').append('<tr>...some information...</tr>'); While the rows ARE added successfully, for some reason, the static rows work with the click handler, but the newly added rows do not. Is there something I'm missing? Thanks in advance!

  • Populating a Datagrid with variable number of columns and rows in Flex

    - by Rie Mino
    I am trying to figure out how to manage a Datagrid based on an XML object like this: <matrix rows="5" columns="5"> <column> <row>0.5</row> <row>0.21</row> </column> <column> <row>0.6</row> <row>0.9</row> </column> <column> <row>0.5</row> <row>0.5</row> </column> <column> <row>0.8</row> <row>0.4</row> </column> </matrix> I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates. Thanks in advanced for your help.

  • Toggle table row siblings

    - by kuswantin
    I have a table structured like this: <table> <tr id="id1" class="parent"></tr> <tr class="id1"></tr> <tr class="id1"></tr> <tr class="id1"></tr> <tr class="id1"></tr> <tr id="id2" class="parent"></tr> <tr class="id2"></tr> <tr class="id2"></tr> <tr class="id2"></tr> <tr class="id2"></tr> .....etc </table> As you can see child classes are coresponding to their parent id. Now I want to toggle all the rows which have class names equal to their parent row id whenever parent row is clicked. I have tried this, perhaps stupid try:) and can't seem to get this working: $('tr.parent').click(function() { //alert('yay'); var tog = $(this).attr('id'); $(this).siblings().hasClass(tog).slideToggle(); return false; }); Thanks.

  • Change table row using Rails Ajax

    - by xopht
    I've a simple page with link_to_remote Rails Ajax function and HTML table. I'd like to change row of the table when click that link. This is my html. <table border="1"> <tr> <td><div id="ajax_result_1">1</div></td> <div id="ajax_result_2"><td>2</td></div> </tr> <div id="ajax_result_3"> <tr> <td>3</td> <td>4</td> </tr> </div> </table> And this is my code. <%= link_to_remote 'Change', :update => "ajax_result_1", :url => "change_path" %> change action just render simple text. When I use ajax_result_1 for :update, it worked okay. But, not for *ajax_result_2* and *ajax_result_3*. Is there a way to solve this? I want to replace row of the table.

  • Efficiently select top row for each category in the set

    - by VladV
    I need to select a top row for each category from a known set (somewhat similar to this question). The problem is, how to make this query efficient on the large number of rows. For example, let's create a table that stores temperature recording in several places. CREATE TABLE #t ( placeId int, ts datetime, temp int, PRIMARY KEY (ts, placeId) ) -- insert some sample data SET NOCOUNT ON DECLARE @n int, @ts datetime SELECT @n = 1000, @ts = '2000-01-01' WHILE (@n>0) BEGIN INSERT INTO #t VALUES (@n % 10, @ts, @n % 37) IF (@n % 10 = 0) SET @ts = DATEADD(hour, 1, @ts) SET @n = @n - 1 END Now I need to get the latest recording for each of the places 1, 2, 3. This way is efficient, but doesn't scale well (and looks dirty). SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 1 ORDER BY ts DESC ) t1 UNION ALL SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 2 ORDER BY ts DESC ) t2 UNION ALL SELECT * FROM ( SELECT TOP 1 placeId, temp FROM #t WHERE placeId = 3 ORDER BY ts DESC ) t3 The following looks better but works much less efficiently (30% vs 70% according to the optimizer). SELECT placeId, ts, temp FROM ( SELECT placeId, ts, temp, ROW_NUMBER() OVER (PARTITION BY placeId ORDER BY ts DESC) rownum FROM #t WHERE placeId IN (1, 2, 3) ) t WHERE rownum = 1 The problem is, during the latter query execution plan a clustered index scan is performed on #t and 300 rows are retrieved, sorted, numbered, and then filtered, leaving only 3 rows. For the former query three times one row is fetched. Is there a way to perform the query efficiently without lots of unions?

  • Quickly or concisely determine the longest string per column in a row-based data collection

    - by ccornet
    Judging from the failure of my last inquiry, I need to calculate and preset the widths of a set of columns in a table that is being made into an Excel file. Unfortunately, the string data is stored in a row-based format, but the widths must be calculated in a column-based format. The data for the spreadsheets are generated from the following two collections: var dictFiles = l.Items.Cast<SPListItem>().GroupBy(foo => foo.GetSafeSPValue("Category")).ToDictionary(bar => bar.Key); StringDictionary dictCols = GetColumnsForItem(l.Title); Where l is an SPList whose title determines which columns are used. Each SPListItem corresponds to a row of data, which are sorted into separate worksheets based on Category (hence the dictionary). The second line is just a simple StringDictionary that has the column name (A, B, C, etc.) as a key and the corresponding SPListItme field display name as the corresponding value. So for each Category, I enumerate through dictFiles[somekey] to get all the rows in that sheet, and get the particular cell data using SPListItem.Fields[dictCols[colName]]. What I am asking is, is there a quick or concise method, for any one dictFiles[somekey], to retrieve a readout of the longest string in each column provided by dictCols? If it is impossible to get both quickness and conciseness, I can settle for either (since I always have the O(n*m) route of just enumerating the collection and updating an array whenever strCurrent.Length strLongest.Length). For example, if the goal table was the following... Item# Field1 Field2 Field3 1 Oarfish Atmosphere Pretty 2 Raven Radiation Adorable 3 Sunflower Flowers Cute I'd like a function which could cleanly take the collection of items 1, 2, and 3 and output in the correct order... Sunflower, Atmosphere, Adorable Using .NET 3.5 and C# 3.0.

  • TableTools only exporting single header row

    - by Rakeesh
    I am using the DataTable jquery plugin from: http://datatables.net/ I have a DataTable that has multi-row table header with colspan. Something like: <thead> <tr> <th>Level 1</th> <th colspan='2'>Level 1 - Item 1</th> <th colspan='2'>Level 1 - Item 2</th> </tr> <tr> <th>Level 2</th> <th>Level 2 - Item 1a</th> <th>Level 2 - Item 1b</th> <th>Level 2 - Item 2a</th> <th>Level 2 - Item 2b</th> </tr> </thead> However when I use the TableTools plugin to export then except for the "Print" option all the rest (Excel, CSV, Pdf etc) only has the "Level 2" header row and not the Level 1. Any suggestions on how to get it to export also Level 1?

  • How to make DataGrid Row really fully selectable (clicking on non-cell area)

    - by Samuel
    The question might be a little misleading. Here is a screenshot of a DataGrid that has some dummy values (code provided below) Is there a way to make the white area not covered by a cell clickable? My intention: I want to have full row selection. This can be achieved by SelectionUnit="FullRow" which is fine but how can I make the white area implicitly select the entire row without expanding available cells in width and avoiding code behind Here is the repro code: Xaml: <Window x:Class="DGVRowSelectTest.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" DataContext="{Binding RelativeSource={RelativeSource Self}}"> <DataGrid ItemsSource="{Binding Names}" SelectionMode="Single" SelectionUnit="FullRow" > </DataGrid> </Window> Dummy Code behind of it (just sets the two entries up) using System.Collections.Generic; using System.Windows; namespace DGVRowSelectTest { public partial class MainWindow : Window { private IList<KeyValuePair<string, string>> _names = new List<KeyValuePair<string, string>>{new KeyValuePair<string, string>("A1", "A2"),new KeyValuePair<string, string>("B1","B2")}; public IList<KeyValuePair<string, string>> Names{get { return _names; }set { _names = value; }} public MainWindow() { InitializeComponent(); } } }

  • CSS Zebra Stripe a Specific Table tr:nth-child(even)

    - by BillR
    I want to zebra stripe only select tables using. I do not want to use jQuery for this. tbody tr:nth-child(even) td, tbody tr.even td {background:#e5ecf9;} When I put that in a css file it affects all tables on all pages that call the same stylesheet. What I would like to do is selectively apply it to specific tables. I have tried this, but it doesn't work. // in stylesheet .zebra_stripe{ tbody tr:nth-child(even) td, tbody tr.even td {background:#e5ecf9;} } // in html <table class="zebra_even"> <colgroup> <col class="width_10em" /> <col class="width_15em" /> </colgroup> <tr> <td>Odd row nice and clear.</td> <td>Some Stuff</td> </tr> <tr> <td>Even row nice and clear but it should be shaded.</td> <td>Some Stuff</td> </tr> </table> And this: <table> <colgroup> <col class="width_10em" /> <col class="width_15em" /> </colgroup> <tbody class="zebra_even"> The stylesheet works as it is properly formatting other elements of the html. Can someone help me with an answer to this problem? Thanks.

  • Return the Column Name for row with last non-null value "Ms Access 2007"

    - by bri1969
    I have a Table, which contains a list of league players. Each season, we record their Points per Dart. Their total PPD for that season is stored in other tables and extracted through other queries, which in turn are imported to the master table "Player History" at the end of the season for use as historical data. The current query retrieves each players PPD for each season they played, when they played last, and how many seasons played. The code for Last season Played has become too long and unstable to use. it was originally created, and split into two separate columns because a single SQL was to long. (LSP1) and LSP2) which work, but as I add seasons, Access does not like the length of code. In short, i need to find a more simple code that will look at each row, and look in that row for the last non null cell and report which column that last non null value is in. So if a player played seasons 30 & 31, but did not play 32..but did play 33, the Column with the code should be titled Last Season Played, and for that Player, it would state "33" in that cell, indicating that this player last played season "33" I will provide both tables and the query.. Please help

  • How do I repeat function over several row.

    - by ChrisBD
    I'll admit that I'm not an Excel guru so maybe someone here can help me. On my worksheet I have several blocks of data. I calculate the sum of all items within column D of that block. Within each block I am checking the value of the cell in column C and if it contains the letter "y" and the value in column D of that row is equal to zero I must exclude the total sum of column D. Currently I am doing this by multiplying the sum value by either 1 or 0 which is produced by running a test over the cell contents. Below is an example of what I am using to test rows 23 to row 25 inclusively for data in Column D. I am also performing the same on Column E and G, but the "y" character is always in column C, hence the absolut column reference. =IF(AND($C23="y",D23=0),0,1)*IF(AND($C24="y",D24=0),0,1)*IF(AND($C25="y",D25=0),0,1) There must be a more efficient way to do this. Ideally I would like to write a function that I can paste into a cell and then select the rows or cells over which I run the test. Can anyone point me in the right direction?

  • Fill lower matrix with vector by row, not column

    - by mhermans
    I am trying to read in a variance-covariance matrix written out by LISREL in the following format in a plain text, whitespace separated file: 0.23675E+01 0.86752E+00 0.28675E+01 -0.36190E+00 -0.36190E+00 0.25381E+01 -0.32571E+00 -0.32571E+00 0.84425E+00 0.25598E+01 -0.37680E+00 -0.37680E+00 0.53136E+00 0.47822E+00 0.21120E+01 -0.37680E+00 -0.37680E+00 0.53136E+00 0.47822E+00 0.91200E+00 0.21120E+01 This is actually a lower diagonal matrix (including diagonal): 0.23675E+01 0.86752E+00 0.28675E+01 -0.36190E+00 -0.36190E+00 0.25381E+01 -0.32571E+00 -0.32571E+00 0.84425E+00 0.25598E+01 -0.37680E+00 -0.37680E+00 0.53136E+00 0.47822E+00 0.21120E+01 -0.37680E+00 -0.37680E+00 0.53136E+00 0.47822E+00 0.91200E+00 0.21120E+01 I can read in the values correctly with scan() or read.table(fill=T). I am however not able to correctly store the read-in vector in a matrix. The following code S <- diag(6) S[lower.tri(S,diag=T)] <- d fills the lower matrix by column, while it should fill it by row. Using matrix() does allow for the option byrow=TRUE, but this will fill in the whole matrix, not just the lower half (with diagonal). Is it possible to have both: only fill the lower matrix (with diagonal) and do it by row? (separate issue I'm having: LISREL uses 'D+01' while R only recognises 'E+01' for scientific notation. Can you change this in R to accept also 'D'?)

  • Alternating table row color, but with 2 rows of data

  • Hide table row onclick using jquery

How can I hide the tr and if its there the tr with the notes_row class below it without affecting the other rows using jquery? So if someone clicked cell3 the tr that link is in is hidden then if there is a notes table row below it, it hides that as well.

  • Adding up row number and displaying total using COUNT (PHP MySQL)

    - by Yvonne
    I'm attempting to run a query that adds up the total number of subjects in a class. A class has many subjects. There is a 'teachersclasses' table between teachers (the user table) and classes. The principles sounds pretty simple but I'm having some trouble in getting my page to display the number of subjects for each class (directly associated with the teacher) This is what I have so far, trying to make use of the COUNT with a nested SELECT: SELECT (SELECT count(*) FROM subjects WHERE subjects.classid = class.classid) AS total_subjects, class.classname, class.classid FROM class Then I am calling up 'num_subjects' to present the total within a while loop: <?php echo $row['total_subjects']?> From the above, I am receiving the total subjects for a class, but within the same table row (for one class) and my other while loop doesnt run anymore, which returns all of the classes associated with a teacher :( ... Bit of a mess now! I know to return the classes for a particular teacher, I can do an additional WHERE clause on the session of 'teacherid' but I think my query is getting too complicated for me that errors are popping up everywhere. Anyone have a quick fix for this! Thanks very much

  • Color Picking Troubles - LWJGL/OpenGL

    - by Tom Johnson
    I'm attempting to check which object the user is hovering over. While everything seems to be just how I'd think it should be, I'm not able to get the correct color due to the second time I draw (without picking colors). Here is my rendering code: public void render() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.applyTranslations(); scene.pick(); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.applyTranslations(); scene.render(); } And here is what gets called on each block/tile on "scene.pick()": public void pick() { glColor3ub((byte) pickingColor.x, (byte) pickingColor.y, (byte) pickingColor.z); draw(); glReadBuffer(GL_FRONT); ByteBuffer buffer = BufferUtils.createByteBuffer(4); glReadPixels(Mouse.getX(), Mouse.getY(), 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, buffer); int r = buffer.get(0) & 0xFF; int g = buffer.get(1) & 0xFF; int b = buffer.get(2) & 0xFF; if(r == pickingColor.x && g == pickingColor.y && b == pickingColor.z) { hovered = true; } else { hovered = false; } } I believe the problem is that in the method of each tile/block called by scene.pick(), it is reading the color from the regular drawing state, after that method is called somehow. I believe this because when I remove the "glReadBuffer(GL_FRONT)" line from the pick method, it seems to almost fix it, but then it will also select blocks behind the one you are hovering as it is not only looking at the front. If you have any ideas of what to do, please be sure to reply!/ EDIT: Adding scene.render(), tile.render(), and tile.draw() scene.render: public void render() { for(int x = 0; x < tiles.length; x++) { for(int z = 0; z < tiles.length; z++) { tiles[x][z].render(); } } } tile.render: public void render() { glColor3f(color.x, color.y, color.z); draw(); if(hovered) { glColor3f(1, 1, 1); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); draw(); glPolygonMode(GL_FRONT_AND_BACK, GL_FILL); } } tile.draw: public void draw() { float x = position.x, y = position.y, z = position.z; //Top glBegin(GL_QUADS); glVertex3f(x, y + size, z); glVertex3f(x + size, y + size, z); glVertex3f(x + size, y + size, z + size); glVertex3f(x, y + size, z + size); glEnd(); //Left glBegin(GL_QUADS); glVertex3f(x, y, z); glVertex3f(x + size, y, z); glVertex3f(x + size, y + size, z); glVertex3f(x, y + size, z); glEnd(); //Right glBegin(GL_QUADS); glVertex3f(x + size, y, z); glVertex3f(x + size, y + size, z); glVertex3f(x + size, y + size, z + size); glVertex3f(x + size, y, z + size); glEnd(); } (The game is like an isometric game. That's why I only draw 3 faces.)

  • what service to restart for /var/log/auth.log to start

    - by Bond
    Here is a situation since the log files on my server had grown to several Gigabytes I took a backup of directory /var/log and then manually when to each subdirectory of /var/log and the files which were big in size I did cat > /var/log/file_which_is_big press 2 times enter key (basically over wrote those files with a blank space) and then Ctrl+C So basically I over wrote those files to be blank. Now when I open /var/log/auth.log I don't see any entry (which is expected also since I over wrote) but when I exit the SSH session and login again then also I do not see any entry in auth.log is there any way other than rebooting the machine to make sure I keep getting the entries in /var/log/auth.log I am not sure which service writes in this file. This is a Ubuntu 10.04 server.

  • Trying to unpack 2.5GB .tar.gz file on Linux but getting "An error occurred while trying to open the archive"

    - by TMM
    Hi, Is there a limit on Linux for the file size of a .tar.gz (or its contents). I am currently creating a .tar.gz (both through the UI/"Compress As" and also through the command line) file for 2 files (6GB and 2GB), and even though it is created successfully, when I try to unpack it using Ark it throws the error "An error occurred while trying to open the archive". I have seen some places that it might be better to archive the file into several smaller .tar.gz files, but I was wondering exactly how to do this (and subsequently unpack the files). Also, is it totally impossible to use the 1 .tar.gz file approach as this would be much simpler. Thanks in advance, Tim
