for 2.0.22 an exception is being thrown when trying to focus a child control of a UserComboBox.DropDownControl
Exception: Invisible or disabled control cannot be activated.
at Wisej.Web.ContainerControl.SetActiveControl(Control value)
There is no problem if DropDownControl is being focused at, as it has no Parent.
But the child controls of DropDownControl are owned by DropDownControl and therefore have a Parent.
Because they are ultimately disconnected from the Form the 2.0.22 now thinks they are invisible/disabled.
Everything works well in 2.0.13. I think this is a regression for #1832.
The second issue is that the UserComboBox.DropDownControl does not work with “Classic-2” theme.
The height of the DropDownControl is not set properly.
Attached a sample for reference.
