If you have built a few Iron Speed applications, then you will have come across Add Record links placed next to your drop downs on your Add and Edit pages. These buttons open a popup containing the Add Record page, which allows you to add a new item which is then added to the drop down on the main page. A slight problem with these popup windows is that they have the full header, footer and menu of a normal page. This generally doesn’t look very nice and can lead to odd situations where the user is browsing the application in the popup rather than the main page.

There are two solutions to this, the obvious one being to create a second version of the Add page in the designer and use this for the pop ups. The second more efficient option is to dynamically change the master page based on where you are coming from. This way you only have one Add page which works like a normal page until its opened by an Add Record link, in which case you switch the page to use the blank master page.

Implementing this in code is very simple. Iron Speed has already done most of the leg work for you. When the Add Record link button is pressed the popup window has a URL parameter called target. You can check for this when the page loads and change the master page if it has a value.

C#

string TargetKey = this.Page.Request.QueryString["Target"];

if (TargetKey != null) {this.MasterPageFile = "../Master Pages/Blank.master";}

VB.Net

Dim TargetKey As String = Me.Page.Request.QueryString.Item("Target")

If Not TargetKey Is Nothing Then

            Me.MasterPageFile = "../Master Pages/Blank.master"

End If
