ComboBox Issues

[nasterhe]

If ComboBox does not select the drop-down after drop-down and expansion in the main window, clicking the drop-down in other places in the main window will automatically collaps, but clicking on the drop-down in other places of the pop-up window in the pop-up window will not automatically collaps, and you need to click the drop-down outside the window to collaps.

Currently I'm doing it with the following code：

this.PointerPressed += OnPointerPressed;


private void On_PointerPressed(object? sender, PointerPressedEventArgs e)
{
    foreach (var item in this.GetVisualDescendants().OfType<ComboBox>())
{
    if (item.IsDropDownOpen)
    {
        item.IsDropDownOpen = false;
 
    }
}
}
