From: Mr. X. on 20 Jun 2010 10:42 I need a way for saving the panel and all of it's component to a file. I understand that Panel is not serializable, but I didn't find any trick to make it be one. I read the article you gave, but didn't find any way for saving the panel. Also did : dim prs() As System.Reflection.PropertyInfo Dim cc .... dim myPanel as Panel .... For i = 0 To MyPanel.Controls.Count - 1 prs = MyPanel.controls(i).GetType().GetProperties() For j = 0 To prs.Count - 1 If prs(j).CanRead AndAlso prs(j).CanWrite() Then cc = prs(j).GetValue(c.ActiveControl, Nothing) ' ***** end if next j next I The inner loop (with the asterisks) doesn't retrieve the properties exactly as I retrieve on design time (property window). I don't need something too much complicated - just to translate to a stream, that can store on a database.

In other words, is how can I serialize a panel. If this cannot be done, so how can I search all of its properties exactly as they are seen on the property editor ?
