       Is it possible to display the RadAjaxLoadingPanel over a RadAjaxPanel (or ASP Panel) using javascript even if you won't have any server event?
       Say, I have several user controls that I load within RadTabStrip. Each user control has their own javascript function that kicks a webservice call. What I want to accomplish is, the moment the javascript initiates the webservice call until the webservice returns a result, I want to display the RadAjaxPanel so the user will know that the transaction is being executed. At the same time, they won't be able to click on anything inside the tab until the webservice returns and prompt that the transaction was successfully completed. Is the use of RadAjaxLoadingPanel possible fo this scenario? Or is there any work around that we can do for this?

    Thanks in advance!

    Hello Arthur,

    You can use the approach suggest in the following demo:
    Show and hide loading panel explicitly

    This is how you can control when to show/hide RadAjaxLoadingPanel.

    Hi Nikolev,

    Is there any way to invoke the Ajax Loading Panel without the sender, args and from the plain javascript?
    I mean, I have a section of the page which uses server side code and another section which uses JQuery to do something else. I wish if I could use the same Loading Panel for both.

    Hello Sharmin,

    You could still use the client show() and hide() methods for the showing and hiding the RadAjaxLoadingPanel, but without sender and args to take the eventTarget you should show it unconditionally or with custom conditions as per your needs.
