In the following example: http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

I would like to add a small spinning .gif in front of the "loading..." text to indicate activity. Is this possible?

You can look in the "LoadCountries()" javascript function of the examples source code to see where the "loading" text gets set.

Hello Greg,

You can try the following approaches in the online help article.
Show/Hide RadAjaxLoadingPanel explicitly.
Ajax / Templates and Transparency.

Thanks,
Shinu.

Hi Greg,

Yes, it is possible to achieve this scenario using JavaScript.

When the items are loaded in the country and city RadComboBoxes you could define an image background for the input fields of the RadComboBoxes and then when selected items are set you could delete the image from the input.

I have made a sample web page, which shows how the scenario in question could be achieved. Please find attached and give it a try.

Hope this helps.

All the best,
Ivana
