Duplicating a Form Component? Cloning etc...

write2jey

I'm trying to duplicate a form componenet such as a ListView or TextBox from one TabPage to the other. I've found two viable solutions so far.... 1) Cloning implementing ICloneable 2) Inheriting from the specified Component and derving the class. Would anyone elaborate the Cloning part? I'll give a head start: But the following throws a stack exception as it goes on in a loop. class RemoteListView:ICloneable { private ListView m_ListView, m_ListClone; //the object I need cloning public RemoteListView (ListView lv) { m_ListView = lv; } public object Clone() { RemoteListView view = new RemoteListView (m_ListView); view.m_ListClone = (ListView)view.Clone(); return view; } } Any input would be much appreciated!!

AW, You're the man! You did it once again. You've done your job in helping me clone the component. Yet, there're issues, but I'll play around with them to resolve. Thanks!! JJ

Hi AW, I'll try this. But I was told someone as using the control's Parent property to switch between the tabpages and updating the control according the tabpage. I'm stuck at the part about how to save the "data" for each control on each tabpage and retrieving them in the "tabPage_SelelctedIndexChanged" event handler. Thank you much. JJ

Why don't You create an another object using constructor (e.g new ...)? You can use System.Reflection as well to copy control: using System.Reflection; ... Control ctrl=(Control)Activator.CreateInstance(myControl.GetType()); To use ICloneable inherit from Your control: public class CloneableControl : Control, ICloneable { public object Clone() { CloneableControl ctb=new CloneableControl(); ctb.Property1=this.Property1; ... ctb.PropertyN=this.PropertyN; return ctb; } }
