  Posted on Mar 2, 2009 (permalink)

  I am able to get to the GridViewRow object during a drop operation into a RadGridView.  I am also able to get to the GridViewRow when handling the RowLoaded event.  However, I'm strugglig getting to a GridViewRow object from a RadGridView object.
  
  What I'm trying to do is determine the selected row(s) (i.e., RadGridView.SelectedRecords), then find the GridViewRow for each selected record so that I can change the colors of the cells.  However, starting with a RadGridView object, I cannot find a way to get to the GridViewRow objects associated with the RadGridView.  How do I do this?

  Hi Geb,

  
  

  Unfortunately, our API does not provide an easy way to get a GridViewRow from the RadGridView.
  

  You have to use the ItemsGenerator property of the GridViewItemsControl to get the GridViewRow for a given index. You can get that index from the DataRecord corresponding to the data item.

  
  

  See the code bellow:

  DataRecord record = (DataRecord)this.gridView.FindRecord(/* data object */);

  bool isNewlyCreated = false;

  ridViewRow item = (GridViewRow)this.gridView.ItemsControl.ItemsGenerator.GenerateItemAtIndex(record.DataSourceIndex, out isNewlyCreated);

  item.IsSelected = true;

  This code will not work for grouped rows.  How can I make this same code work if my GridView is grouped?  The GenerateItemAtIndex returns a GridViewGroupRow, not a GridViewRow. 
  
  

  GridViewRow item = (GridViewRow)this.gridView.ItemsControl.ItemsGenerator.GenerateItemAtIndex(record.DataSourceIndex, out isNewlyCreated);

  
  Thanks.

  Hi Hector,
  
  Can you please give me more details on  your specific scenario. Meanwhile the RadGridView API  has evolved and I believe we can find a better solution here.

  Do you need access to the selected rows , or you need the row over which the user clicked or you need the UI row for a given datasource element  ..or something else ?

  If I have more details I will gladly provide you with a working sample.
  
  Best wishes,

  Hi,
  
  I am having anotyher issue.
  I have create a grid column as shown below
  
  <grid:GridViewColumn HeaderText="Trend" Width="120">
                          <grid:GridViewColumn.CellStyle>
                              <Style TargetType="gridView:GridViewCell">
                                  <Setter Property="Template">
                                      <Setter.Value>
                                          <ControlTemplate TargetType="gridView:GridViewCell">
                                              <Border BorderThickness="0,0,0,1" BorderBrush="#FFB3B3B3">
                                                  <StackPanel Orientation="Horizontal">
                                                      <Button x:Name="btnTrend" Content="Trend" ></Button>
                                                  </StackPanel>
                                              </Border>
                                          </ControlTemplate>
                                      </Setter.Value>

  Hi Anwar,
  
  You can use our extension methods to find this button:
  
  var button = e.Row.ChildrenOfType<Button>().Where(b=>b.Name == "btnTrend").FirstOrDefault();
  if(button != null)
  {
     // your code goes here
  }
  
  Best wishes,

  Hi,
  
  Thanks for the quick response.But it did not work for me. I am not able to get the function called "ChildrenOfType". I have installed the latest DLL's. Still no luck?
  Here is the error message
  Error 1 'Telerik.Windows.Controls.GridView.GridViewRowItem' does not contain a definition for 'ChildrenOfType' and no extension method 'ChildrenOfType' accepting a first argument of type 'Telerik.Windows.Controls.GridView.GridViewRowItem' could be found (are you missing a using directive or an assembly reference?) E:\Projects\AFAttributeViewerSL\AFAttributeViewerSL\Page.xaml.cs 81 32 AFAttributeViewerSL
  
  Can you please solve this issue?
  
  Thanks,
  Anwar

  Hello Anwar Arakkal,
  
  To be able to access the ChildrenOfType method you will have to unclude the Telerik.Windows.Controls namespace.
  
  

  using Telerik.Windows.Controls;

  
  That should fix the problem.
