    Hi, I have another function that populates the selected items from my AutocompleteBox. I want to remove the typing capabilities of my AutoCompleteBox. But I would like to still remove any items selected. 


    May I ask how would that be accomplished?

    Hello Minh,

    In order to achieve the desired by you functionality of RadAutoCompleteBox using the ChildrenOfType<T> you need to get the WaterMarkTextBox placed inside the AutoCompleteBox and set its ReadOnly property to True. Thus the TextBox part of the control will be read only (you wont' be able to type inside it) and at the same time you will be able to remove the selected items:
    private void RadAutoCompleteBox_Loaded(object sender, RoutedEventArgs e)
        var auto = sender as RadAutoCompleteBox;
        var waterMarkTextBox = auto.ChildrenOfType<RadWatermarkTextBox>().FirstOrDefault();
        if(waterMarkTextBox != null)
            waterMarkTextBox.IsReadOnly = true;

    Hope this helps.
