Asked By surendra kakani on 06-Dec-11 11:07 PM

I am getting script error while my page is loading

Here i am getting the error

Sys.WebForms.PageRequestManager._initialize('ctl00$ScriptManager1', document.getElementById('aspnetForm'));

Sys.WebForms.PageRequestManager.getInstance()._updateControls(['tctl00$ContentPlaceHolder1$UpdPnlManageEntity'], [], [], 90);

this is because of control ID , It may be possible that you have given wrong ID,

for checking control's client ID , see view source of page.

Solutions:

Add a script manager to the master page.

do like the following example:

<asp:ScriptManager ID="sm1" runat="server">
  <Scripts>
    <asp:ScriptReference Path="Init.js" />
  </Scripts>
</asp:ScriptManager>
<asp:UpdatePanel ID="up1" runat="server">
  <ContentTemplate>
    <!-- Interesting content goes here -->
  </ContentTemplate>
</asp:UpdatePanel>

Init.js
-----

Sys.Application.add_init(AppInit);
 
function AppInit(sender) {
  Sys.WebForms.PageRequestManager.getInstance().add_endRequest(End);
}
 
function End(sender, args) { }

there is no tag xhtmlConformance in my web.config

Try by moving the <script type="text/javascript"></script> block containing the Sys.* calls lower down (to the last item before the close of the body's <asp:Content/> section) in the HTML on the page.

Is your <script> block ahead of your ScriptManager?
