ContextMenu & which cell was clicked ?...

[Paul]

Hi,

We are using a context menu on a RadTreeListView component.
This menu must show different options depending upon which cell or column etc... was right-clicked.

The trouble is that, the following code returns the columnIndex of the cell that currently has the focus, NOT the one that was right-clicked as this cell does not recieve the focus  prior to the right-click & context menu being shown.

 

 

int columnIndex = ((GridViewDataControl)(((RadContextMenu)(e.Source)).UIElement)).CurrentColumn.DisplayIndex;

 

is there any way to determine the cell, and/or column and/or data item for the "point" where the mouse was right-clicked ?...

We can only do manual interception of righ-clicks if there is no context menu defined - if we apply a context menu (which we prefer) then the right-click handler will not fire in our code-behind.

Is there any way to do this please ?...

Thanks - Paul.

Hi Paul,

You may handle the Opening event of the RadContextMenu and find the underlying cell through the GetClickedElement<T>() method:

private void RadContextMenu_Opening(object sender, Telerik.Windows.RadRoutedEventArgs e)
        {
            RadContextMenu menu = (RadContextMenu)sender;
            GridViewCell clickedCell = menu.GetClickedElement<GridViewCell>();
            if (clickedCell != null)
            {
                var columnIndex = clickedCell.Column.DisplayIndex;
            }
        }

Thus depending on the column index, you may perform the logic you require.
