Finding the GridViewRow from a RadGridView object

[GEB]

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;

Works great! Thanks.

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>
                                </Setter>
                            </Style>
                        </grid:GridViewColumn.CellStyle>
                    </grid:GridViewColumn>

I need to enable or disable the the button(btnTrend) on the RowLoaded event. I am not able to find the control in RowLoaded event.
Can you please help me on resolving this request? Please correct me if the above XAML code is wrong.

Thanks,
Anwar

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
}

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.
