DataGrid with button in sub DataGrid

Posted By:      Posted Date: October 28, 2010    Points: 0   Category :WPF
 

I have a datagrid with another datagrid in the row details.  This works well and everything shows up.  However in my sub datagrid, i have a column that just holds a button.  If i try to attach any events (click, previewmousedown, etc.) the xaml parser blows up with a null exception at runtime.  If i take out the event in my xaml, everything else works fine.

Is this a known issue?  If so is there a workaround that someone has come up with?

Thanks.

Here is my XAML:

      <DataGrid.RowDetailsTemplate>

       <DataTemplate>

        <DataGrid Margin="25,0,0,3" ItemsSource="{Binding TaskStaff}"

    			    ScrollViewer.HorizontalScrollBarVis

Click.CommandParameter null when binding on Button inside DataGrid DataGridTemplateColumn

  
I am having trouble getting a Click.CommandParameter to pass through with a bound Click.Command. I have a DataGrid with a DataGridTemplateColumn that contains a couple of Buttons. Using a suggestion found on the forum (http://social.msdn.microsoft.com/Forums/en/wpf/thread/541024a9-3d7e-4c6a-b88e-9a7eb7ee83a9), I was able to get the Click.Command to bind to the right command, but when arriving in the corresponding method in my ViewModel, the parameter is null.  Here is my xaml for my DataGridTemplateColumn <data:DataGridTemplateColumn Header="Case">  <data:DataGridTemplateColumn.CellTemplate>   <DataTemplate >    <StackPanel Orientation="Horizontal" HorizontalAlignment="Center">     <Button Content="Open" Margin="6,0" command:Click.Command="{Binding RelativeSource={RelativeSource AncestorType={x:Type data:DataGrid}}, Path=DataContext.OpenCaseCommand}" CommandParameter="{Binding}"  />     <Path Data="M1,1 L1,2" Stroke="#FFCCCCCC"/>     <Button Content="Rename" />    </StackPanel>   </DataTemplate>  </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> I used Snoop to see what was going on.

Delete DataGrid row (WPF) by clicking Delete key button

  

Hi,

I have WPF 4 desktop-based application. In one of the windows of this application I have DataGrid with data, binded with SQL Server database (via ADO.NET Entity Framework). In order to manipulate with data I have delete button, that deletes selected row from DataGrid and call SaveChanges() method.

Now I want to add support for keyboard manipulations, e.g. i want to let user to remove row by selecting and clicking on Delete keyboard button.

If I set CanUserDeleteRows="True" in window's XAML, it removes selected row, but doesn't make commit to database, in other words, it doesn't call SaveChanges() method.

I tried to add keyDown event handler to DataGrid an check if (e.Key == Key.Delete), so run remove method that removes selected row and call SaveChanges() method, but it doesn't work.

My question is how can I add keyboard event handler to DataGrid that will let remove selected row and call SaveChanges() method or just run my own method, that deals w

How to format and update GridView and DataGrid rows using JQuery

  
The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

ListBox tricky to set in a DataGrid/GridView

  
Listboxes are very tricky to set selected items in grid - there is no real nice way to do it. It would have been great if Microsoft included a property that accepts an array or comma separated values - or anything! But they only allow each item in the list to be selected individually. The way to do this in a grid is a bit messy, but it is fairly simple to implement. When a row is created (as per the event), select the items of the listbox as per the datagrid source data:

How to highlight datagrid or GridView row on mouse over?

  
This article will show how you can Ajax with GridView to display popup messages when mouse moves over certain column. In the demo project I have added first column as an image column with a help icon in it. This kind of implements a feature that if you want more information about the row you can move mouse over this icon, a asynchronous request is sent to server for data about that row and when call returns the returned message is show as a popup message.

Multiple Column Dropdownlist for the ASP.NET DataGrid

  
Based on my previous control "Multiple Column DropDownList for ASP.NET", I received many emails asking for the same control to be used in the DataGrid for web applications. Here we go.. This control can be used as the regular MS DropDownList in the DataGrid and also as a regular dropdownlist. It has all the properties, like DataTextField, DataValueField, DataSource, SelectedIndex etc. The download file contains the samples both in VB.NET and C#. In this sample, I have used the Northwind database of SQL Server.
