I'd like to see a Drag And Drop manager functioning something like the AJAX manager.
You can select controls that can be draggable and then define drop targets for them.

Things it might include:
* Constrained movement, either X, or Y or within a boundary.
* Init distance.  Eg. you have to drag an object 20px to start moving it.
* Drag handle.
* Snap. to grid, or elements

Please add screenboundary detection for expandable menu items.

When there is not enough space for menu items to expand on the right side, expand them to the left side and vice-versa.

See attached screenshot for more information

It would be useful for the header cell for Sort-able columns to display an indication that the column can be sorted.  This is useful to users when not all columns are sort-able, so they know which header cells will trigger resorting.

Elsewhere in our application, we use a double headed arrow icon to indicate use can click on header to resort on the column; the app displays the up or down arrow indicating when sort order is active.

Suggest adding a third Sort-Image-URL attribute to specify an image to use when column is not sorted ascending or descending.

At present, best I can do declaratively (w/o custom coding) is the set one of the HeaderStyle-Font properties (for example the HeaderStyle-Font-Underline) to provide a visual indication that column is sort-able.

In it's current state the RadButton only emulates the looks of a SplitButton, but not the behaviour.

In my point of view, such control should prove valuable to customers. More over, there is a growing need of base controls since we already have a at least three such implementations.

A RadSplitButton should be the base (or it's base should be the base) for all control specific implementations of a split button

"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

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.
