[Solved] Click event for GridViewSelectColumn checkbox

[FirstName]

Hi, all. How can I catch click action for any checkbox in GridViewSelectColumn via MVVM or smth else ?

XAML markup contains only one grid with two column (first is selectable checkboxes):

<telerik:RadGridView ...
                             namespace:MySelectedItemsBindingBehavior.SelectedItems="{Binding SelectedItemsHere}"
 ...>
    <telerik:RadGridView.Columns>
        <telerik:GridViewSelectColumn CheckBoxStyle="{StaticResource CheckBoxStyle}"/>
            <telerik:GridViewDataColumn ...>
            <telerik:GridViewDataColumn.CellTemplate>
                <DataTemplate ...>
                    <StackPanel ...>
                        ...
                    </StackPanel>
                </DataTemplate>
            </telerik:GridViewDataColumn.CellTemplate>
        </telerik:GridViewDataColumn>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

P.S. Exactly click event, not the changing of underlying collection.

Hello,

One possible approach would be to handle the CellLoaded event of the RadGridView control, check if the loaded cell's Column property is of type GridViewSelectColumn and attach a handler for the MouseLeftButtonDown event with the handledEventsToo parameter of the AddHandler method set to True.

private void ClubsGrid_CellLoaded(object sender, CellEventArgs e)
{
    if (e.Cell.Column is GridViewSelectColumn)
    {
        e.Cell.RemoveHandler(MouseLeftButtonDownEvent, new MouseButtonEventHandler(OnClick));
        e.Cell.AddHandler(MouseLeftButtonDownEvent, new MouseButtonEventHandler(OnClick), true);
    }
}

private void OnClick(object sender, MouseButtonEventArgs e)
{
    var cell = sender as GridViewCell;
    e.Handled = false;
}

Please let me know whether such an approach would work for you.
