    Hy Team !
    I am showing the DropDown menu on focus with this code :

    private void RadAutoCompleteBox_GotFocus(object sender, RoutedEventArgs e)
                var autoComplete = (RadAutoCompleteBox)sender;
                string searchText = autoComplete.SearchText;
                if (autoComplete.SelectedItem != null)
                    searchText = BindingExpressionHelper.GetValue(autoComplete.SelectedItem, autoComplete.DisplayMemberPath).ToString();


    This works but it also disable the left click when I try to select something from this list. Every other way are working (right click, keyboard control, ...) just the left click doesn't.

    So what can I do to fix this issue ?

    Hello Jeremy,

    The observed by you behavior of RadAutoCompleteBox could be observed when the control is not populated correctly. When the Populate method gets called you need first to check whether the DropDown is not opened:
    private void radAutoCompleteBox1_GotFocus(object sender, RoutedEventArgs e)
        var radAutoCompleteBox = sender as RadAutoCompleteBox;
        if (!radAutoCompleteBox.IsDropDownOpen)

    Please, check the proposed above approach and let us know if it resolves your issue.

    Hopes this helps.
