AsyncPostback Trigger Update Panel Does Not Work in IE

In my application, the AsyncPostback trigger of the update panel does not work in IE 9 and IE 10 , but it works in IE 8, and postbacktrigger also works in the whole version of IE.

It gives an error

Sys.WebForms.PageRequestManagerParserErrorException: A message received from the server cannot be parsed.

I tried several things before posting this issue:

  • async = true in tag
  • registration of postback at page loading (this cannot be used because the update panel is located throughout the system)
  • async permission in web configuration

<asp:UpdatePanel runat="server">
                                   <ContentTemplate>
                                       <cc:BinNumberMultiDropDown runat="server" TabIndex="3"    ProgramTrue="true" ID="ddl_bin_number"
                                           CssClass="multiselect">
                                       </cc:BinNumberMultiDropDown>
                                       <asp:RequiredFieldValidator ID="rfv_ddl_bin_number" runat="server"    ControlToValidate="ddl_bin_number" ValidationGroup="vg_rate"    Display="Dynamic"
                                           SetFocusOnError="true"></asp:RequiredFieldValidator>
                                   </ContentTemplate>
                                   <Triggers>
                                       <asp:AsyncPostBackTrigger ControlID="ddl_program" EventName="SelectedIndexChanged" />
                                   </Triggers>
                               </asp:UpdatePanel>

Please offer me a solution

I also found that this error only appears on Winodws 8 systems
