Hello,

I am using editable WebDropDown and Infragistics Web version 11.1.
When user select data from List and submit, I can get value from "CurrentValue" and index from "SelectedItemIndex" properties during postback in button OnClick event. 
But if user delete value with "Delete" keybord button and click button, "CurrentValue" and "SelectedItemIndex" properties keep previous value during OnClick event.
