Hello Everybody,

I found a new problem. I have created two user controls, first hv username and password field and submit button and second user control have menus which can be seen by login. I have added these two control in a div panel of a web page. Initially first user control will be loaded and when user will click on submit button than I want to unload first user control and load second control which contains menu. I can load / unload any user control dynamically in a div but I dont know how can I unload user control while click on button within itself and load other user control. So please help me. Feel free to contact us.

You don't need to "unload" user controls... just do this in your button click. 

userControl1.Visible = false;

userControl2.Visible = true;

Let's say you have a <div> with an ID="divUserControls" and runat="server".  Have you tried putting code like the following in your Button_Click event?

Protected Sub UC_ButtonClick(byval sender as object, byval e as systme.eventargs)
  ' Me refers to this instance of the usercontrol.
  ' Parent would be the parent control, in this case <div>
  Me.Parent.Controls.Remove(Me.ID)
End Sub

 Or, you could load both controls initially and set visibility and enabled properties to make it look how you want.

Or, if the first method doesn't work, just create an event within your first control, and raise that event when your button is clicked.  Then the page the controls are on can take care of disabling and enabling controls. This would probably be the easiest and most efficient way, since you may use the first control in a different app without the second control.

This is what I said above... and it's really the easiest way to go.
