Backspace key getting sent to browser
using Telerik radDropdownList in a toolbar causes page to go back

Hello,

I have a new issue that has come up with using our custom Telerik RadDropdownlist control in the add-in express toolbar.
The control works when typing a word into it, it has built in autocomplete which comes up and shows the possible suggestions and does type-ahead as well.

However when trying to backspace while the autocomplete dropdown is open, the backspace is sent to the browser and causes the page to go back in one page in the history.
Not only that, because it is going to IE instead of the dropdown, it will not backspace while the dropdown is open.

In investigating this further, I see that whenever i press a normal key it fires Keydown and Keyup events, keydown is Raddropdownlistelement, keyup is raddropdownlist which is the wrapper for the control collection
when pressing backspace, only the keyup on raddropdownlist is fired and the backspace goes to the browser and doesn't delete a letter from the textbox in the raddropdownlist control.

Now I know you probably don't deal with Telerik controls, but any ideas how I can suppress the backspace from getting to the browser?

I will be sending the same question to telerik as well.

Hi Kyle,

Is the base class of Telerik controls 'System.Windows.Forms.Control' class?

If I drill down enough it looks like it gets back to the System.Windows.Forms.Control.
RadDropDownList inherits from RadControl which inherits from ScrollableControl which inherits from Control
