Hi, So i use PopupControlExtender (to edit some of the fields) inside ListViewControl which itself is embeded inside an UpdatePanel.
The problem is as follows whenever you cause partail postback the popup panels are created client side outside the updatepanel. And you get more clientside controls with the same clientside ID. When you postback with popup panel the server side control eg. Texbox has Text = clientsidecontrol1.text, clientsidecontrol2.text, clientsidecontrol.text3
Is there a way to prevent this.

public partial class Secure_Test : System.Web.UI.Page

{
PopupControlExtender pce = AjaxControlToolkit.PopupControlExtender.GetProxyForCurrentPopup(Page);
pce.Commit("Popup");
InputLabel.Text = InputTB.Text;
}
}
To make it easier to test i post the code of an example page i used for testing. To make myself clear here is an example: i click Popup. Type "asdf" in the textbox and click Submit. InputPanel dispalys "asdf" i click Popup again. Type "qwerty" in the textbox and click Submit. InputPanel now displays "qwerty,asdf" When you check it the firebug you get this:
