Context Menu on a Group Row in RadGridView - silverlight

Question

I found one old solution Here.
But GridViewExpander is obsolete in 2009. Proof Here.
How can i implement it (Context Menu on a Group Row in RadGridView) in another way?

Answer 1

No answers... =(
But i found solution.
The are two ways to solve it:
1) If you need custom style for your GridViewGroupRow - read about Templates Structure
2) If not, then just use somthing like this:
<TelerikNavigation:RadContextMenu.ContextMenu>
<TelerikNavigation:RadContextMenu Opened="RadContextMenuOpened" ItemClick="ContextMenuItemClick" x:Name="contextMenu">
</TelerikNavigation:RadContextMenu>
private void RadContextMenuOpened(object sender, RoutedEventArgs e)
{
var menu = (RadContextMenu)sender;
if (menu == null)
return;
var cell = menu.GetClickedElement<GridViewCell>();
var row = menu.GetClickedElement<GridViewRow>();
var groupRow = menu.GetClickedElement<GridViewGroupRow>();
if (cell != null && row != null)
{
if (!cell.DataColumn.IsFrozen)
{
//Code for current cell
}
}
if (groupRow != null)
{
//Code for groupRow
}
}
private void ContextMenuItemClick(object sender, RadRoutedEventArgs e)
{
if (_currentCell != null)
{
//Code for current cell
}
if (_currentGroupRow != null)
{
var menu = (RadContextMenu)sender;
var clickedItem = e.OriginalSource as RadMenuItem;
if (clickedItem != null)
{
foreach (var gridViewRow in _currentGroupRow.ChildrenOfType<GridViewRow>())
{
foreach (var gridViewCellBase in gridViewRow.Cells)
{
if (gridViewCellBase.Column.UniqueName == "PlanObject")
{
var val = gridViewCellBase.DataContext as YourObjectName;
if (val != null)
{
//.....
}
}
}
}
//....
}
}
}
