Remove not hide User Control, posting againHi all I am new to VB.NET and am using VB.NET 2005. I have an MDI form with a Split Container Control. On demand I am adding and removing User Controls on Panel 2. I am using Show() and Hide(). It works perfectly. The only thing is I would like to remove the User Control from memory instead of hiding. I tried Dispose(), however then I cannot show this user control again. UserControl.Parent=Form.SplitContainer1.Panel2 UserControl.Dock=DockStyle.Fill UserControl.Show() .. .. UserControl.Hide() Thanks.

I mean is it possible for me to show the user control again and again on
demand with the same behaviour as it was displayed for first time (firing load event etc.) instead of using Hide() which probably is the same thing as Visible=False. Thank you.

That's the whole rationale behind instantiating objects.
Just create an new instance of the component, set all the relevant properties as required and hook up the event handlers as required and Bob's your uncle.

Of course you only have to instance it from its class and add it to your form again. Dim myControl as New myUsercontrol. me.controls.add(myControl) And set than the right properties again.

Whenever you need a control again, you can create it, set it's properites and add it to the container (TheContainer.Controls.Add). If you have a variable declared using "WithEvents" that was previously pointing to the former control, you can assign the new control to this variable again and all event procedures will be working just like with the former control. If you don't have a WithEvents variable, use the AddHandler statement to attach event handlers to the new control. Armin
