Hi again,

I can now make it work when popups are enabled by the following line in my page_load event using client side scripting.

     this.ASPxButton1.ClientSideEvents.Click = "function(s, e) {" +
                        EditUrl(string.Empty, string.Empty, "Edit", "tid=0") + "}";

however if I turn "supports popups" off in the module definition this code does nothing obviously because it reverts to a web url which is useless in a click event.

Is it possible to detect in a module whether "supports popups" is enabled or rather how can I make the button work regardless of whether popups are enabled or not?

Core Popups have been a big mess since they were first added to the system.  Most people I know avoid using them - there are many threads that discuss the weird issues that they cause in different environments.

However - that said - modules that need to be able to render INSIDE a popup require different code in BUTTONS to ensure that they work correctly as you have discovered.

If you want to KNOW if the page that is currently being rendered is inside a popup - you need to test the querystring  for popUp=true.

            Boolean isActivePopup = false;
            if (!string.IsNullOrEmpty(Request.QueryString["popUp"]))
            {
                String myPopup = Request.QueryString["popUp"];
                if (myPopup == "true")
                {
                    isActivePopup = true;
                }
            } 

if isActivePopup is true - then you can set the button to work from inside a popup.
