Sys.WebForms.PageRequestManagerParserErrorException:

The message received from the server cannot be parsed, and the common reason for this error is that the response filter, httpmodules, or server trace is enabled when the corresponding modification is made by calling Response.Write ().

More information: An error occurred while parsing the nearby "output content".


Here's how to fix it:

1. If the server control that calls the Response.Write () method is using a UpdatePanel page, you only need to add a <Triggers> node under UpdatePanel. Register with Postbacktrigger to change the control. The code is as follows:

1. <asp:scriptmanager id= "ScriptManager1" runat= "Server" >
2. </asp:ScriptManager>
3. <asp:updatepanel id= "UpdatePanel1" runat= "Server" >
4. <Triggers>
5. <asp:postbacktrigger controlid= "Button2"/> <!--Button2 is the one that needs to be used in button2_click Events Response.Write () The button id-->
6. </Triggers>
7. <ContentTemplate>
8. <asp:button id= "Button2" runat= "Server" onclick= "button2_click" text= "button"/>
9. <asp:updateprogress id= "UpdateProgress1" runat= "Server" >
Ten. <ProgressTemplate></ProgressTemplate>
One. </asp:UpdateProgress>
</ContentTemplate>
</asp:UpdatePanel>

2. However, if you are using UpdatePanel in a master page, you cannot resolve the above method, or you may experience an error similar to the following:

A control with ID ' Btnexport ' could isn't being found for the trigger in UpdatePanel ' UpdatePanel1 '.

This is mainly because UpdatePanel1 cannot find the controls registered in <asp:postbacktrigger controlid= "Btnexport"/>, because we generally do not add this control (Btnexport) to the master page. (Of course, if a control with ID Btnexport is added under the UpdatePanel <ContentTemplate> node, there is no error.) ）

If such an error occurs, my workaround is to add the following code to the Page_Load event where the page number of the control where the Response.Write () method is needed is used:
((ScriptManager) Master.findcontrol ("ScriptManager1")). RegisterPostBackControl (Btnexport);
ScriptManager1 is <asp:scriptmanager id= "ScriptManager1" runat= "Server" > </asp:ScriptManager> ID
