    I am attempting to use your Silverlight ComboBox to autosuggest data.  I have the ComboBox working with the RadComboBox items bound/populated via a WCF service which returns a set of 10 choices.  This works fine and I am able to update the options based on the data entered into the textbox portion of the control.  The issue I have is the when you press the spacebar, as required for the space between word, the control closes the list of options despite the fact that I have the StaysOpenOnEdit="True".  It also does not seem to enter the space into the field until I press spacebar a second time.  Then if you open the list of options the text field becomes highlight/selected so that if you start typing you over-write your waht you already typed.  In order to work around this I tried adding the following in a KeyUp and KeyDown methods:

    if (e.Key == Key.Space)


    ((RadComboBox)sender).Text = String.Concat(((RadComboBox)sender).Text.ToString(), " ");
    e.Handled =



    this does not seem to prevent the close of the list and it places the cursor in the text field to the begining - another issue.  I also tried adding a statement that set the IsDropDownOpen = true but this caused entered text to be highlighted. 

    Is there a way to either deselect the entered text or open the list without effecting the selection of the entered text?

    Hello Chris,

    This is a known problem in RadComboBox, which will be resolved in the next update of RadControls for Silverlight, which is due in several days.

    Best wishes,
