GridView With Radiobutton column

[Kiran]

Hi

I have a requirement where I need to add a radiobutton as first column of the grid and when the user selects the radiobutton the row should be selected I mean selecteditem should be set for the grid. I have used the below code to show the radio button in the grid but I am not able bind the radiobutton selection to the SelectedItem.

<telerik:GridViewDataColumn Name="GridColumnSelector" Header="">
    <telerik:GridViewDataColumn .CellTemplate>
        <DataTemplate>
               <RadioButton Name="rdCheck" GroupName="RadioSelectors" />
        </DataTemplate>
    </telerik:GridViewDataColumn .CellTemplate>
</telerik:GridViewDataColumn >

Regards
Kiran

Hi Kiran,

You may handle the Checked event of the RadioButton and find its parent row by using the ParentOfType<> extension method. Afterwards, all you need to do is to set that particular row to be the selected one:

private void rdCheck_Checked(object sender, RoutedEventArgs e)
{
    RadioButton radioButton = sender as RadioButton;
    GridViewRow parentRow = radioButton.ParentOfType<GridViewRow>();
    if(parentRow != null)
    {
        parentRow.IsSelected = true;
    }
}

You may find more information about the ParentOfType<> extension method in this blog post.

Hi

Thanks for prompt response. I implemented the same way as before but now I get following error. I am not sure if I have to add any references. 

private void RadioRowSelection_Click(object sender, RoutedEventArgs e)
{
     RadioButton radioButton = sender as RadioButton;
     GridViewRow parentRow = radioButton.ParentOfType<GridViewRow>();
     if (parentRow != null)
     {
          parentRow.IsSelected = true;
     }

}

'System.Windows.Controls.RadioButton' does not contain a definition for 'ParentOfType' and no extension method 'ParentOfType' accepting a first argument of type 'System.Windows.Controls.RadioButton' could be found (are you missing a using directive or an assembly reference?)
