Column Name by clicking?

[bonedoc]

I have a datagrid, and I need to get the name of it by a click event (of the headers). I have been playing around with this, but no luck. I get a null ref:

Private Sub dataGrid_MouseUp(ByVal o As Object, ByVal mea As MouseEventArgs) Handles dataGrid.mousedoubleclick
 
Dim hitTest As DataGrid.HitTestInfo
 
' Get the name of the column that was clicked.
 
messagebox.show(dataTable.Columns(hitTest.Column).ColumnName)
 
End Sub

You also have to perform the hittest to get some value into that empty variable (hitTest). Do this and it will work if your dataTable is an actual instance of a DataTable. You should name your variables and objects to avoid such confusion!

[SIZE=2][COLOR=#0000ff]Dim[/COLOR][/SIZE][SIZE=2] hitTest [/SIZE][SIZE=2][COLOR=#0000ff]As[/COLOR][/SIZE][SIZE=2] DataGrid.HitTestInfo = dataGrid.HitTest(e.X, e.Y)
[/SIZE]
