Hey guys, I'm having a problem with a telerik grid causing a full page postback and not showing the grid after the postback. Here's the window definition with the ajax in the .aspx.

<body style="padding: 0px; margin: 0px auto; width: 750px; height: 530px; background-color: #FFFFFF;"> <form id="form2" runat="server"> <telerik:RadScriptManager ID="ScriptManager1" runat="server"> </telerik:RadScriptManager> <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> <telerik:AjaxSetting AjaxControlID="pgSingleInvitation"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="tabsAddSingleUser" /> <telerik:AjaxUpdatedControl ControlID="multiPageAddSingleUser" LoadingPanelID="RadAjaxLoadingPanel2" /> </UpdatedControls> </telerik:AjaxSetting> <telerik:AjaxSetting AjaxControlID="pgReInvitation"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="tabsAddSingleUser" /> <telerik:AjaxUpdatedControl ControlID="multiPageAddSingleUser" LoadingPanelID="RadAjaxLoadingPanel2" /> </UpdatedControls> </telerik:AjaxSetting> <telerik:AjaxSetting AjaxControlID="ajaxRadGrid2"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="RadGrid2" LoadingPanelID="RadAjaxLoadingPanel2"/> </UpdatedControls> </telerik:AjaxSetting> </AjaxSettings> </telerik:RadAjaxManager> <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel2" runat="server" Skin="Windows7" /> <script type="text/javascript"> function CloseAndRebind() { GetRadWindow().BrowserWindow.refreshGrid(); GetRadWindow().close(); } function CloseAndError() { GetRadWindow().BrowserWindow.location.reload(); GetRadWindow().close(); } </script> <telerik:RadSkinManager runat="server" ID="SkinManager2" Skin="Default"> </telerik:RadSkinManager> <div style="margin: 0 auto; padding: 20px 0 0 30px; overflow:auto; height: auto">    <telerik:RadTabStrip runat="server" ID="tabsAddSingleUser" MultiPageID="multiPageAddSingleUser" SelectedIndex="0" CausesValidation="false" > <Tabs> <telerik:RadTab PageViewID="pgSingleInvitation" Text="Single Invite" Width="120px"/> <telerik:RadTab PageViewID="pgReInvite" Text="Re-Invite" Width="120px"/> </Tabs> </telerik:RadTabStrip> <div />

And here is the grid in the same .aspx file.

<telerik:RadPageView runat="server" ID="pgReInvite"> <div class="pageContent2"> <div class="home_class_main_box_2"> <telerik:RadGrid ID="RadGrid2" runat="server" Width="673px" Height="1050px" AllowPaging="True" AllowSorting="True" OnPageIndexChanged="grid_PageIndexChanged" AllowMultiRowSelection="true"<br

And last here's the C# code for the initialization of the grid, this is called from the page load method.

private void getStudentsData(int type) { string sortExpression = (string)ViewState["sortExpression"]; string sortDirection = (string)ViewState["sortDirection"]; if (type == 5) { IsReady = true; } else { IsReady = false; } try { string sql =

"Select b.student_class_id, a.student_id, a.first_name as first_name, a.last_name as last_name,a.nickname as nick_name,a.username as uniqueId, "

; sql += "a.student_email,b.remoteid, case b.status WHEN " + VConstants.STUDENT_STATUS_REGISTERED + " then 'Active' WHEN " + VConstants.STUDENT_STATUS_INVITED + " "; sql += "then 'Invited' WHEN " + VConstants.STUDENT_STATUS_DELETED + " THEN 'Deleted' WHEN " + VConstants.STUDENT_STATUS_READY + "THEN 'Ready' WHEN " + VConstants.STUDENT_STATUS_BLOCKED + " then 'Inactive' WHEN " + VConstants.STUDENT_STATUS_PENDING + " THEN 'Pending' end as status "; sql += "from student a, student_class b "; sql += "where a.student_id = b.student_id "; sql += "and (b.status = " + VConstants.STUDENT_STATUS_INVITED + " or b.status = " + VConstants.STUDENT_STATUS_READY + ") "; sql += "and b.class_id=" + currentClass.class_id + ""; sql += " ORDER BY A.student_id desc "; DataTable dt = dbUtility.getDataTable(sql); DataView dv = new DataView(); dv = dt.DefaultView; if (!string.IsNullOrEmpty(sortExpression)) { dv.Sort = sortExpression + " "

+ sortDirection;                }                RadGrid2.DataSource = dv;                RadGrid2.DataBind();            }

catch (Exception ex) { Utils.PreserveStackTrace(ex); } }

I've also added two screen shot attachments, one before the filter and one after the filter.

Thanks for your time!
