HI,
I am using a Telerik AJAX Manager to have a button control update a MultiPage control.
My Multipage contains several pageviews that each contain a reportviewer control. On the first load, everything works great. However when I do a postback, I get my updated pageviews and everything appears correct, but there are JS errors everytime I move the mouse over the pageview or click on the reportviewer control. I also get the errors when changing tabs. They are preventing me from being able to use reportviewer features such as printing and paging.
Most errors are: "Microsoft JScript runtime error: Object expected"
When I remove do a full postback by setting the postback URL of the button, everything works and I get no JScript errors. I think this has to do with the viewstate, but I'm not sure.
Any help is much appreciated.
Thanks!
Billy

Hello Billy,
I think it will be best if you can open a support ticket and send us a simple running project (incl. your custom skin, CSS, images, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.
Thanks beforehand for your patience and cooperation,

Hi Paul,
Unfortunately, I won't be able to send a working project because the reports are server reports hosted by SSRS. Here are code samples from the markup...
<telerik:RadScriptManager ID="RadScriptManager1" Runat="server"/> |
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> |
<AjaxSettings> |
<telerik:AjaxSetting AjaxControlID="cbM0010"> |
<UpdatedControls> |
<telerik:AjaxUpdatedControl ControlID="cbM0016" /> |
</UpdatedControls> |
</telerik:AjaxSetting> |
<telerik:AjaxSetting AjaxControlID="btnUpdate"> |
<UpdatedControls> |
<telerik:AjaxUpdatedControl ControlID="RMPReports" LoadingPanelID="RALP" /> |
</UpdatedControls> |
</telerik:AjaxSetting> |
</AjaxSettings> |
</telerik:RadAjaxManager> |
<telerik:RadAjaxLoadingPanel ID="RALP" runat="server" BackgroundPosition="Center"> |
<img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' |

Thanks Billy for posting the above problem. I am also getting the similar kind of error when I am trying to load ReportViewer Control to RadPageView. It throws me a JS error as below:
"Problems with this webpage might prevent it from being displayed properly or functioning properly. In future, you can display this message by double-clicking the warning icon displayed in the status bar.
Line: 414
Char: 1
Error: Object expected
Code: 0
"
I tried to load different other control to the RadpageView & it works fine but does not work when loading ReportViewer Control. I am not sure if RadPageView support ReportView control...
If any one already tried to use the above controls and got any success please let me know.
Thanks,
Sanjay.

Hi there,
Could you please check if your code works out of RadMultipage control and if everything is fine after ajax update?

Hi Paul,
I am using the RadTabStrip and RadMultiPage inside a ajax:TabPanel, which is inside ajax updatepannel. Do you think, is that some thing to do with the error. I was going through some outside forums which indicate some incompatibility between Reportviewer Control & ajax update pannel. Can you please let me know more about this?
Thanks,

Hi Sanjay,
I'm afraid the issue is not related to any Telerik control, therefore we cannot help further on the matter.
