Dim dgi As DataGridItem
‘dgdFormTypes is the id for Datagrid.   

For Each dgi In dgdFormTypes.Items 
        Code = dgi.Cells(4).Text
        Name = dgi.Cells(5).Text        ‘If Datagrid has some Control in any column then
        Dim ctlInt As Control = dgi.Cells(1).FindControl(“chkInt”)        ‘ Get the value of that Control, in this case its a Checkbox
        CType(ctlInt, CheckBox).Checked
