This example illustrates how you can define different templates for the RadAjaxLoadingPanel control to display custom images during an AJAX request.
It also demonstrates the transparency feature of RadAjaxLoadingPanel, which allows your application to show the loading panel without hiding the updated control.
A "replacing" effect could still be achieved in cases that have no transparency (value 0); the updated control will be "replaced" by the loading panel during the AJAX update.
The transparency of the loading panel is set in percentage. The default value is 0 – the loading panel is not transparent and covers the updated control. Changing the transparency value to 100 will make the loading panel fully transparent.
