[Solved] LoadingPanel to show progress indicator?

[John]

Hi:

I am working on an application that does some processing when the user clicks a button, and I'd like to show a progress indicator while the code runs. I followed the RadAjaxLoadingPanel example and got the indicator to show, but then the code doesn't work. So in the attached images 1 and 2 show what happens with no LoadingPanel, the user clicks Login and the code populates the drop-down.

When I add the Loading Panel it shows the indicator, 3.png, but then when it is finished the drop-down does not populate, see 4.png.

Can anyone make a suggesiton as to how I can get this to work?

Thanks in advance for any and all advice.

John.

If you could supply your code it would be easier to assist. Thank you.

Hi:

I have attached the files...please note the authtentication and drop-down loading is done from a Dynamics CRM installation, but it should be relatively easy to modify to have the drop-down populate some other way no? Note I had to change the file extensions to ".png"

HI:

I changed the code in the cmdLogin method to this:

    Thread.Sleep(5000);
    for (int i = 0; i < 25; i++)
    {
      drpActiveRfps.Items.Add(i.ToString());
    }


Same result, the drop-down does not populate...

Hi John,

I suggest that you try setting the LoadingPanelId of the RadAjaxPanel and remove the RadAjaxManager. Another option is to replace the RadAjaxPanel with ASP:Panel and ajaxify it with the RadAjaxManager as described here.
