How to set a Datagrid Column to invisible when that Column is an AutoGeneratedColumn

In the DataGrid’s declaration, add the following code in OnItemDataBound event
VB.NET

Dim dv As DataView = DataGrid1.DataSource ’Bind you DataGrid1 in Page_Load to DataView
Dim dc As DataColumnCollection = dv.Table.Columns
e.Item.Cells(dc.IndexOf(dc('field_name))).Visible = false

C#

DataView dv = DataGrid1.DataSource ;//Bind you DataGrid1 in Page_Load to DataView
DataColumnCollection dc = dv.Table.Columns;
e.Item.Cells[dc.IndexOf(dc['field_name'])].Visible = false;
