The SelectionChanged event is fired before Page_Load, hence when the ViewState is applied, it overrides the changes made inside the OnSelectionChanged handler.
Example - Clearing the CheckBox selection of a RadComboBox inside SelectionChanged
Workaround - Create a custom boolean property on the page and set it to true inside the SelectionChanged. Then, in Page_Load or the OnLoad event of any control, execute your logic based on the custom boolean property value.
No direct way to select the prev/next month and year buttons - While the calendar is open and focused, note that there is no way to focus and use the month and year changing buttons in the calendar header
We are having a touchscreen problem with the RadSearchBox, specifically on the MicroSoft surface touchscreen. I have tested this out on mobile phone and other tablets, but the problem occurs on the Surface.
The issue is that you cannot change the SearchContext, because it never seems to recognize the touch event.
You can touch the SearchContext to initiate the drop-down event, but then it is impossible to select an item from the list.
There are no other problems with Telerik controls on the Surface (the touch events on RadDropDown, RadTabStrip, RadComboBox, RadMenu, etc.) all seem to be working fine.
"Loading..." text in Combobox with Virtual Scrolling is visible on first set of items loading. It shows first time "Loading..." text. on scrolling it loads items from PageMethods/WebService but "Loading..." text it not visible i.e. because it is first <LI> item so it is not visible. Instead of first <LI> item, it should be at position where it always display while loading more items. same issue is also in telerik demo website : http://demos.telerik.com/aspnet-ajax/combobox/examples/populatingwithdata/autocompletesql/defaultcs.aspx
