It’s published in a few places, but I had to do a few Google searches before confirming that you should use NamingContainer property to get parent DataGrid for DataGridItem. So I’ve created a shared method in my WebFormsHelper class.
Public Shared Function ParentDataGrid(ByVal Item As DataGridItem) As DataGrid
‘ Dim gridTable As DataGridTable = Item.Parent ‘DataGrid = gridTable.Parent doesn’t work because MS declared DataGridTable as private(why?)
Dim grid As DataGrid = Item.NamingContainer
