Hi Hrushikesh Mokashi,

Please note that it is not supported scenario to add single tab or PageView in the RadAjaxManager settings. You should add the whole MultiPage or TabStrip in order to have the project working properly.  Also could you please let me know whether the problem persists if the Ajax is disabled on the page.
Some more code snippet represents your settings will be helpful to research further on the problem.


Sincerely yours,

              </updatedcontrols>
          </telerik:AjaxSetting>


But when i add the following setting then  it give me javascript error.


<telerik:AjaxSetting AjaxControlID="Button1">
              <updatedcontrols>
                  <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
              </updatedcontrols>
          </telerik:AjaxSetting>

Hi Hrushikesh Mokashi,

I  believe the RadGrid is nested in PageView. If this is the scenario the presented error is expected because, as I mentioned you should add the whole MultiPage in the Ajax setings.

All the best,

Hi,

Yes RadGrid is nested in PageView.

I have added the Multipage in AjaxSetting
The Ajax setting are follows.

<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
      <ajaxsettings>
             
          
<telerik:AjaxSetting AjaxControlID="Button1">
              <updatedcontrols>
                  <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
              </updatedcontrols>
          </telerik:AjaxSetting>
          
         
                   
           <telerik:AjaxSetting AjaxControlID="RadTabstrip1">
              <updatedcontrols>
                  <telerik:AjaxUpdatedControl ControlID="RadMultiPage1" />
              </updatedcontrols>
          </telerik:AjaxSetting>
          <telerik:AjaxSetting AjaxControlID="RadMultiPage1">
              <updatedcontrols>
                  <telerik:AjaxUpdatedControl ControlID="RadTabstrip1" />
              </updatedcontrols>
          </telerik:AjaxSetting>
         
                            
         <telerik:AjaxSetting AjaxControlID="RadGrid1">
              <updatedcontrols>
                  <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
              </updatedcontrols>
          </telerik:AjaxSetting>

Hi Hrushikesh,

When you ajaxify RadMultiPage control with RadAjax, an UpdatePanel will be generated to wrap all controls in RadMultiPage. Thus you don't need to explicitly ajaxify any other control in RadMultiPage.

You can find example attached to this forum post which replicates your scenario.


All the best,

I am having this same issue, and have submitted a support ticket also. I understand that the update panel gets wrapped around every control by simply adding the ajax setting to the multipage control. 

However I want to do the same thing as the person that originated this post does. For some reason, the grid is not getting the Loading Panel when the button is clicked. This is a big problem on my end since there needs to be some sort of activity that the end user sees, or he/she will continue to hit the button, which will then get our users frustrated because it will eventually not show up at all.

Any more help on this issue would really help!!

Thanks
Rob
