AutoCompleteBox: When the Populate method is called from the control's GotFocus or PreviewMouseLeftButtonDown events, moving the parent Window does not close it's DropDown
When the Populate method is called from the control's GotFocus or PreviewMouseLeftButtonDown events, moving the parent Window does not close it's DropDown.

Available in LIB Version 2016.3.1010, it will be also available in the 2016 R3 SP1.

The workaround worked for me in VB.NET when used as follows:
 
Dispatcher.BeginInvoke(New Action(Sub() auto.Populate("searchText")))

Another workaround is to called the Populate method from within a Dispather:
private void RadAutoCompleteBox_GotFocus(object sender, RoutedEventArgs e)
{
    var auto = sender as RadAutoCompleteBox;
    Dispatcher.BeginInvoke(new Action(() => { auto.Populate("searchText"); }));
}

Also, this bug happens even without calling Populate(). Steps to reproduce:
1) Click on AutoCompleteBox
2) Enter something so that dropdown should appear
3) Click at entered text
4) Move a window

Thanks for the workaround, but this bug still needs to be fixed. How can I do this, when AutoCompleteTextBox is in UserControl, not Window?

Workaround:
Use the LocationChanged event of the parent Window instance and set the IsOpen property of any Popup instance related to the RadAutoCompleteBox to False. The next code snippet shows the described workaround:

In the XAML code:
<Window LocationChanged="OnWindowLocationChanged" ...>
      <telerik:RadAutoCompleteBox x:Name="AutoCompleteBox" .../>
</Window>
In the event handler:
private void OnWindowLocationChanged(object sender, EventArgs e)
{
    var popups = this.AutoCompleteBox.ChildrenOfType<Popup>();
    foreach (var popup in popups)
    {
        if (popup.IsOpen)
        {
            popup.IsOpen = false;
        }
    }
}
