I've a serious problem with RadComboBox
When Filtering RadComboBox IE 9 , it works fine actually with markfirstmatch property and i could filter with more than one character
For example if i am filtering Combobox to find item with name "AmrRafat", i could write 'amr' and the combobox will do the rest and finds this item.
but when trying the same scenario in IE 11, it only accepts the first character and each time i am pressing a key it consider it as the first character for filtering
For example if i am filtering Combobox to find item with name "AmrRafat", and i tried to write 'amr' Then Combobox will assume only one character and filter with it
