Page Error

I am getting the following error and have no idea where to start looking. Also you should know that this page is ran in a 3rd party app and this is where I get the error. In debug and if I hit the page directly I do not get the error. The app returns this User-Agent header from a trace.

Try to disable these lines *temporarily* and the actual problem will be revealed.

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnablePartialRendering="False">
</asp:ToolkitScriptManager>

I ended up with this error.

The control with ID 'UpdatePanel2' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

Thanks,

sammySeltzer

Ok, please look in web.config file and see if there is an entry like this:

<xhtmlConformance mode="Legacy"/>

If you see it, please remove it and try running your code again to see if it fixes it.

Not there.

sammySeltzer

wow!

There is only one thing else I can try.

Change this line:

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnablePartialRendering="False">
</asp:ToolkitScriptManager>

to this line:

<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnablePartialRendering="False" CombineScripts="False">
</asp:ToolkitScriptManager>

and see what happens

I assume you are talking about this part of the code?

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(startRequest);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequest);

How would I handle partial rendering? sorry, but I am very new at this stuff.

DowntownIT

ASKER

I removed all of this code.

<script type="text/javascript">
Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(startRequest);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequest);

function startRequest(sender, e) {
//disable button during the AJAX call
document.getElementById('<%=cmdSubmitChanges.ClientID%>').disabled = true;
document.getElementById('<%=cmdSubmitChanges.ClientID%>').value = 'Updating Records...';
document.getElementById('<%=cmdMoveToRequested.ClientID%>').disabled = true;
document.getElementById('<%=cmdMoveToRequested.ClientID%>').value = 'Updating Records...';

}
function endRequest(sender, e) {
//re-enable button once the AJAX call has completed
document.getElementById('<%=cmdSubmitChanges.ClientID%>').disabled = false;
document.getElementById('<%=cmdSubmitChanges.ClientID%>').value = 'Submit Changes';
document.getElementById('<%=cmdMoveToRequested.ClientID%>').disabled = false;
document.getElementById('<%=cmdMoveToRequested.ClientID%>').value = 'Not Needed';
}

</script>

In doing so, My page works with no errors. This code was used to prevent the user clicking buttons while the DB was being updated so I wonder if there is a better way of doing that.

GlobaLevel

you DO want to use the pagerequestmanager class to handle partial page renderings...see

I removed all of the code using the PageRequestManager.
