I have replicated the issue with RadAjaxManager
and everything is working correctly. Please find my test project attached. I have also reviewed your code but I am unable to find anything unusual. Which controls do you update with the RadAjaxManager
Keep in mind that RadUpload (and the standart upload too) can't upload files using ajax
so, if your grid is ajaxified you need to attach an event handler on the OnRequestStart
client-side event of the RadAjaxPanel (or RadAjaxManager), which will disable the AJAX functionality
if a specific button (say upload button) is clicked.
Please refer to my attachment or this demo
for an illustration of the scenario.
If none of this helps you, would you please send us a sample running project describing the issue in order to assist you better.
All the best,
the Telerik team
