Reference Controls from MasterPage

To reference controls from a master page in a normal page use the following syntax:

Ex. Reference the Head Html tag of the Master Page from a normal page to add scripts in the head. Set the Head as runat=”server” and give id=”Head”, then enter the following syntax:

HtmlHead headTag = ((HtmlHead)((MasterPageName)this.Master).FindControl(“Head”));

Hope this helps. Btw this will mostly be used in Visual Studio 2005 since in the new versions, you can add an ContentPlaceHolder in the Head tag of the Master page and insert any scripts in the PlaceHolder on the page

Quickie | ‘Sys’ is undefined Solution

Today I was trying to call a web service from Java Script using the Sys.Net.WebServiceProxy.invoke function but the following error was loading:

‘Sys’ is undefined

The problem was because the ajax was not being referenced in the website. The solution I found was to create a new website in Visual Studio 2005 and use the AJAX Control Toolkit Web Site Template. When I ran the code again, no error was loaded and everything worked fine!
