Hello,

I have a problem with the group collaspe/expand. My grid is not grouping by default. If I drag a column to group it, it works. When I collapse it, it also works but when I want to expand the collapsed columns, it won't works. I don't have any error (javascript or server-side).

There's my code :

<%@ Page Language="C#" EnableEventValidation="false" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="GetVersionMapping._Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" CellSpacing="0" GridLines="None" ShowGroupPanel="True" >

<HeaderContextMenu CssClass="GridContextMenu GridContextMenu_Default"></HeaderContextMenu>

<MasterTableView HierarchyDefaultExpanded="True" >

<Columns>

<telerik:GridBoundColumn DataField="Platform" HeaderText="Platform" UniqueName="Platform">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Client" HeaderText="Client" UniqueName="Client">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Application" HeaderText="Application" UniqueName="Application">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Version" HeaderText="Version" UniqueName="Version">

</telerik:GridBoundColumn>

<telerik:GridDateTimeColumn DataField="Date" HeaderText="Publication Date" UniqueName="Date">

</telerik:GridDateTimeColumn>

</Columns>

</MasterTableView>

<ClientSettings AllowDragToGroup="True" >

</ClientSettings>

</telerik:RadGrid>

</div>

</form>

</body>

</html>

Can you see a problem in my code ?

Thanks by advance.
