  ajax - PagerequestManagerParserErrorException

  Jan 18, 2013 06:10 AM|LINK

  I am new to Ajax and trying to  integrate Ajax in my application(.NET framework 2.0)...I am facing an issue which i couldn't resolve...Here is the error message

   

  System.WebForms.PageRequestManagerParserErrorException:The message received from the server could not be parsed. Common causes for this error are when the response is modified by the calls to Response.Write(),response filters, HttpModules or the server trace is enabled..

   

  I did find lot of forums with this Error Message but none of them were helpful....My web application doesn't have Response.Write, response.filters but i do have a HttpModule(which stores the cookie information), I modifed the code to handle the requests from ajax differently using the code snipette

  if (HttpContext.Current.Request.Headers["x-microsoftajax"] == null)

   

  but still doesn't work....Any suggestions??

  Hi

  It is not a good practice to use Response.Write or server.execute from within an ASP.NET page in general. As UpdatePanels work by intercepting the page rendering process you are recieving the errors.

  You can put the code to generate the data in an HTTPHandler or you can make the button a PostBackTrigger.

  Because of the way updatepanels manage the DOM elements within them, you cannot use Response.Write() with them.

  I think the problem is because of button control in the GridView...I tried to include Triggers inside the updatePanel, now its giving a different error message
  
  A control with ID 'Button_Apply" could not be found for the trigger in UpdatePanel 'UpdatePanel_test'

  
  

  <asp:ScriptManager ID="ScriptManager_Test" runat="server" EnablePartialRendering = "true">
  </asp:ScriptManager>
  <asp:UpdatePanel ID="UpdatePanel_Test" runat="server">
  <ContentTemplate>
  <%--<div style="OVERFLOW-Y:auto; LEFT:141px; WIDTH:"100%"; POSITION:absolute; TOP:100px; HEIGHT:315px">--%>
  <asp:GridView ID="GridView_Test" runat="server" Width="100%"
  DataKeyField="TestID" AllowPaging="True" AllowSorting="True"
  OnPageIndexChanging="GridView_PageIndexChanged" onSorting="Gridview_Sorting"
  OnRowCreated = "GridView_RowCreated" autogeneratecolumns="false" PageSize="10"
  style="margin-top: 0px" >
  <HeaderStyle ForeColor="White" CssClass="ColumnHead" Font-Strikeout="False" HorizontalAlign="Left"></HeaderStyle>
  <RowStyle Wrap="False" CssClass="GridRow"></RowStyle>

  <columns>
  <asp:Boundfield DataField="ClaimID" SortExpression="ClaimID" HeaderText="ClaimID" ControlStyle-BorderStyle="None" ControlStyle-CssClass="ColumnHead" HeaderStyle-CssClass="ColumnHead" HeaderStyle-HorizontalAlign="NotSet" HeaderStyle-BorderStyle="NotSet">

  </asp:Boundfield>--%>
  <asp:TemplateField HeaderText="Corrected Action">
  <ItemTemplate>
  <asp:DropDownList ID="Corrected_action" runat="server" Width="180px" >
  </asp:DropDownList>
  </ItemTemplate>
  </asp:TemplateField>
  <asp:TemplateField HeaderText="">
  <ItemTemplate>
  <%-- <asp:DropDownList ID="Corrected_action" runat="server" Width="180px">
  </asp:DropDownList> --%>
  <asp:Button ID="Button_Apply" runat="server" Text="Apply" CssClass="Button" Enabled="True" CommandName="Submit" ></asp:Button>
  </ItemTemplate>
  </asp:TemplateField>
  </columns>
  <PagerStyle BorderStyle="None" CssClass="GridViewPager"></PagerStyle>
  </asp:GridView>
  <%-- </div>--%>
  </ContentTemplate>
  <Triggers>
  <asp:AsyncPostBackTrigger ControlID = "Button_Apply" EventName="Click" />
  </Triggers>
  </asp:UpdatePanel>
