Context Menu on Grid

I have looked over this code, but it does not work for me.

The error is on this line:

Dim objGrid As DataGrid = CType(sender, DataGrid)

The error received states:

"Specifid Cast not valid."

I need to right click on a grid (I have several grids on a page) and get the grid name or selected grid.

Hi Gary2397;

Well the other code is wrong. When you click on a context menu and go into its click event as below the object sender is not the DataGrid but always the MenuItem object that was selected. So to get the control that the menu item was click on you must use the context menu object itself. In the code sample below replace the ContextMenu1 with the name of your ContextMenu.

    Private Sub MenuItem1_Click(ByVal sender As Object, _
        ByVal e As System.EventArgs) Handles MenuItem1.Click

        Select Case ContextMenu1.SourceControl.Name
            Case "DataGrid1"
                MessageBox.Show("DataGrid 1 Was Right Clicked On")
            Case "DataGrid2"
                MessageBox.Show("DataGrid 2 Was Right Clicked On")
            Case "DataGrid3"
                MessageBox.Show("DataGrid 3 Was Right Clicked On")
            Case "DataGrid4"
                MessageBox.Show("DataGrid 4 Was Right Clicked On")
        End Select

    End Sub

Thank you. The code works perfect. The original code will be misleading to other people who view it, because it doesn't work. But someone accepted it as a correct answer. Thanks.
