[Gtk-sharp-list] UnhandledException

[Sascha Manns]

Hello list,

after Baltasars great help the GUI with Gtk3 comes up correctly. But if
i'm use a combobox and change the content to another entry, i'm getting:

Marshaling changed signal
Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to
handle the exception.
System.Reflection.TargetInvocationException: Exception has been thrown
by the target of an invocation. ---> System.InvalidCastException:
Specified cast is not valid.
  at Gtk.ComboBox.get_Entry () [0x00007] in
<ec8213242a4d4273b7793f86792f85d5>:0
  at PublicanCreators.TestForm1.OnCboDocTypeChanged (System.Object
sender, System.EventArgs e) [0x00008] in
/home/sascha/RiderProjects/PublicanCreators/src/PublicanCreators/Glade.cs:132


Can anyone explain me, what happen`d?

I'm using in the Changed and Move Active Handler:

DocType = cboDocType.Entry.ToString();

Greetings
Sascha
