Hi,
I am trying to "Ajaxify' my Radgrid. This page works without the RadAjaxPanel but not with?
| <html xmlns="http://www.w3.org/1999/xhtml"> |
| <head runat="server"> |
| <title></title> |
| <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server"> |
| <script type="text/javascript"> |
| //<![CDATA[ |
| function openWin() { |
| var oWnd = radopen("ColumnsPopup.aspx", "RadWindow1"); |
| } |
| function OnClientClose(oWnd, args) { |
| __doPostBack('__Page', 'PostbackFromJs'); |
| } |
| //]]> |
| </script> |
| </telerik:RadCodeBlock> |
| </head> |
| <body> |
| <form id="form1" runat="server"> |
| <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> |
| </telerik:RadScriptManager> |
| <telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" |
| ReloadOnShow="true" runat="server" Skin="Sunset"> |
| <Windows> |
| <telerik:RadWindow ID="RadWindow1" Behaviors="Close" OnClientClose="OnClientClose" |
| NavigateUrl="ColumnsPopup.aspx" runat="server"> |
| </telerik:RadWindow> |
| </Windows> |
| </telerik:RadWindowManager> |
| <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default"> |
| </telerik:RadAjaxLoadingPanel> |
| <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" Height="200px" Width="300px"> |
| <input value="Open Popup" type ="button" onclick="openWin();" /> |
| <asp:Button ID="Button1" runat="server" Text="pdf" /> |
| <telerik:RadGrid ID="ResultsGrid" runat="server" EnableHeaderContextMenu="True" GridLines="None" |
| PageSize="3" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" |
| AllowMultiRowSelection="True"> |
| <ExportSettings ExportOnlyData=true IgnorePaging=false Pdf-AllowAdd=true > |
| <Pdf PageHeight="11in" PageWidth="36in" /> |
| </ExportSettings> |
| <MasterTableView AutoGenerateColumns="true"> |
| <Columns> |
| <telerik:GridClientSelectColumn> |
| </telerik:GridClientSelectColumn> |
| </Columns> |
| <RowIndicatorColumn> |
| <HeaderStyle Width="20px"></HeaderStyle> |
| </RowIndicatorColumn> |
| <ExpandCollapseColumn> |
| <HeaderStyle Width="20px"></HeaderStyle> |
| </ExpandCollapseColumn> |
| </MasterTableView> |
| <ClientSettings AllowColumnsReorder="True"> |
| <Selecting AllowRowSelect="True" /> |
| </ClientSettings> |
| </telerik:RadGrid> |
| </telerik:RadAjaxPanel> |
| <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>" |
| SelectCommand="SELECT * FROM [Customers]"></asp:SqlDataSource> |
| <div> |
| </div> |
| </form> |
| </body> |
| </html> |
this is the code behind:
| Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load |
| BindGrid() |
| ResultsGrid.DataBind() |
| End Sub |
| ''' <remarks></remarks> |
| Protected Sub BindGrid() |
| Dim sqlconnection As SqlConnection = New SqlConnection(SqlDataSource1.ConnectionString) |
| sqlconnection.Open() |
| Dim ds As DataSet = New DataSet() |
| Dim da As SqlDataAdapter = New SqlDataAdapter("select * from customers", sqlconnection) |
| da.Fill(ds) |
| ResultsGrid.DataSource = ds |
| End Sub |
| Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click |
| ResultsGrid.MasterTableView.ExportToPdf() |
| End Sub |
thanks

Hello Dingen,
Generally speaking, the exporting feature of the control work with regular postbacks only. The reason is the grid prepares additional information when performing export operation (available on postback).
To bypass this limitation you can wire the OnRequestStart event of the ajax panel, determine whether the target control is ajaxified and explicitly disable its ajax mode to export with regular postback.
