DotNetNuke has a new ability to show PopUp's much more easily!  You can make entire modules work in a single popup or extend module functionality and usability.

There are  few different ways to show a PopUp window in DNN.  It really depends upon how you want to execute it.  Each 3 are very simple once you understand how to use the methods.

 

Server Redirect

 

string redirectUrl = UrlUtils.PopUpUrl(redirectUrl, this, PortalSettings, false, true);

Response.Redirect(redirectUrl);

 

 

Hyperlinks

 

HyperLink myLink = new HyperLink();

myLink.Text = "Click to make a PopUp";

myLink.NavigateUrl = "";

myLink.Attributes.Add("onclick","return" + UrlUtils.PopUpUrl(myLink.NavigateUrl, this, PortalSettings, true, false));

 

 

Action Controls

 

string redirectUrl = this.ModuleContext.NavigateUrl(tabId, controlKey, false, new string[] {});

Response.Redirect(redirectUrl);
