Code to prevent groups from being collapsed not working

[andieje]

Hi

I have a grouped grid and I am trying to prevent the groups from being collapsed by hiding the expand collapse button. I have followed the info in the help file and i have tried both approaches (column created event and grid pre render event) but the column is refusing to disappear!

    Protected Sub gridJourneys_ColumnCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridColumnCreatedEventArgs) Handles gridJourneys.ColumnCreated
        If TypeOf e.Column Is GridGroupSplitterColumn Then
            e.Column.HeaderStyle.Width = Unit.Pixel(0)
            e.Column.HeaderStyle.Font.Size = FontUnit.Point(0)
            e.Column.ItemStyle.Width = Unit.Pixel(0)
            e.Column.ItemStyle.Font.Size = FontUnit.Point(0)
            e.Column.Resizable = False

        End If
    End Sub

    Private Sub gridJourneys_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles gridJourneys.PreRender

        For Each column As GridColumn In gridJourneys.MasterTableView.RenderColumns
            If (TypeOf column Is GridGroupSplitterColumn) Then

                column.HeaderStyle.Width = Unit.Pixel(0)
                column.HeaderStyle.Font.Size = FontUnit.Point(0)
                column.ItemStyle.Width = Unit.Pixel(0)
                column.ItemStyle.Font.Size = FontUnit.Point(0)
                column.Resizable = False
            End If
        Next
    End Sub

The code is detecting the GridGroupSplitterColumn in both cases but it is not affecting the column appearance. In fact i can't make the column any bigger in those code snippets either.

I have set the client side resizable property to true

Here is the grid in case there are any pertinent properties you need to see there

<telerik:RadGrid ID="gridJourneys" runat="server"  Width="960px" AutoGenerateColumns="False" GridLines="None" skin="SkyBlue">
<MasterTableView DataKeyNames="JourneyID" CommandItemDisplay="Top" Name="Journeys" ShowFooter="True" ShowGroupFooter="True" >

 <td colspan="2"> <span class="title"><asp:Label ID="lblTitle" runat="server" Text="Title"></asp:Label></span> </td>
 </tr>
 <tr>
    <td>No Journeys</td>
    <td><asp:Label ID="lblNoJourneys" runat="server"></asp:Label></td>
 </tr>
 <tr>
    <td>Total Distance</td>
    <td><asp:Label ID="lblTotalDistance" runat="server"></asp:Label></td>
 </tr>
 <tr>

    <td><asp:Label ID="lblTotalDuration" runat="server"></asp:Label></td>
 </tr>

 </table>

  </CommandItemTemplate>

<NoRecordsTemplate>
There are no journeys on this date.

Hi

I found this old thread from when i had this same problem last year

http://www.telerik.com/community/forums/aspnet-ajax/grid/can-t-hide-expand-and-collapse-images-in-radgrid.aspx

None of the solutions suggested by Telerik worked for me. The only thing that solved the problem was to add this to my aspx page

.RadGrid_SureTrack

 

.rgCollapse

 

{

 

visibility:hidden !important;

 

}

</

 

style>

 

I would respectfully request that telerik include this tip in their help documentation. As someone from teh telerik team has said in the post referred to above, thsi area of the docs does need updating so i hope this could be added too in case it helps someone else when the other ideaa fail
