    The down arrow key does not seem to be detected in the KeyDown event of the RadComboBox. However, the down arrow key is picked up the KeyUp event.

    Is this a bug or expected behaviour? Is there a work around so that I can get the down arrow key being picked up in the KeyDown event?

    Hi Carl,

    We handle KeyDown event in the RadComboBox control. I would suggest you to use AddHandler in order to handle the KeyDown event. For example:

    this.radComboBox.AddHandler(KeyDownEvent, new KeyEventHandler(radComboBox_KeyDown), true);
    I hope this helps.

    Sincerely yours,

    Hi George

    I have been experiencing a very tiffy issue with radcombobox. I want to invoke a server side event from radcombobox when i enter any text under radcombobox control. Suppose if i enter any text such as "George" etc under radcomboxbox immediately george details such as company, phone and other variables should appear under the radcombobox like a dropdown.

    Could you please let us know the client side or server side events other than text_changed or selected index changed events. I have already tried this when I enter name under radcombobox and click mouse outside radcombobox the events text-changed and selected index changed events fire. 

    My client is really complaining about this problem so I have to solve the solution as soon as possible. Could you please help me and mail me to

    Hi Sunil,

    The Silverlight runs only on the client side and RadComboBox control has no events that fire on server side as well. I would suggest referring to our new RadAutoCompleteBox control which could suit your needs:

        1. Documentation -
        2. Online demos -

    Hope this helps.
