I am creating a simple DotNetNuke module, and every time I add a control that contains ajax, it somehow interferes with the menu of the edit page. This control is one of Syncfusion, and it is a numeric text field. The page and menu function works well while I use standard Microsoft user controls. For example, if I change the ajax numeric text field for asp.net or html, then it works well. As soon as I add the ajax text box, the page editing menu does not work. Has anyone else experienced this issue?
Additional Information: The Syncfusion control does not require any specific version of jQuery. There is no error in the DNN Event Viewer. I tried to track tracks with FireBug but it doesn't detect anything.
I attached a screenshot to help visualize the problem.
