Hide GridTemplateColumn

[Chase Florell]

I have a GridTemplateColumn that can only be visible to specific roles within my system.  My problems is that I cannot figure out to hide it... any help would be great.

    Protected Sub RadGrid1_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles RadGrid1.ColumnCreated
        If e.Column.UniqueName = "Edit" Then e.Column.Visible = False

    End Sub 'RadGrid1_ColumnCreated

Hi,

Try hiding the Template column in the Grid PreRender event as shown below.

CS:

     Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As EventArgs)
         For Each col As GridColumn In RadGrid1.MasterTableView.RenderColumns
             If (col.ColumnType & "GridTemplateColumn") AndAlso (col.UniqueName & "Edit") Then
                 col.Display = False
             End If
         Next

     End Sub

Thanks
Shinu.

Sorry no dice.  If I use that code straight up I get error : 'GridTemplateColumn' is a type and cannot be used as an expression
If I remove (col.ColumnType = GridTemplateColumn) AndAlso

The column still appears in the form.

Have you any other suggestions?

Chase, you pretty much had it right in the initial sample you posted.

 

If TypeOf e.Column Is GridBoundColumn Then
If e.Column.UniqueName = "Edit" Then e.Column.Visible = False
End If

 

 

Ought to do it for you.

I'm actually working on the same type of stuff right now.
My entire code is:

    Sub gridEvil_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles gridEvil.ColumnCreated
        If TypeOf e.Column Is GridBoundColumn Then
            Dim col As GridBoundColumn = DirectCast(e.Column, GridBoundColumn)
            If col.UniqueName = "MealPeriodID" Then
                col.Visible = False
            End If
        End If
    End Sub

Yes, called mine gridEvil.  It's gonna be......  :-(

Awesome thanks, This seems to have done it for me.

    Protected Sub RadGrid1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.PreRender
        For Each col As GridColumn In RadGrid1.MasterTableView.RenderColumns
            If col.UniqueName = "Edit" Then
                If (Page.User.IsInRole("Business Trader Advanced")) Or (Page.User.IsInRole("Business Trader Administrator")) Then
                    col.Display = True
                Else
                    col.Display = False
                End If
            End If
        Next
    End Sub
