setting the text value of a control on the master page, from a content page

[Aussie Rules]

Hi,

Within the code of a content page, how do you say set the .text value of a
label thats on the master page....

Thanks

Label MasterPageLabel = (Label)Master.FindControl("MasterPAgeLAbelID");
MasterPageLabel.Text ="some words";

Master.FindControl returns a reference to the master page control.

Another solution is to have a class for your master page (say its called
myMP) with
properties. Then in you content code you do the following.

In master page code

Public Property MyLabelText() as string
Get
return MyLabel.Text
End Get
Set (MyLabelText as string)
MyLabel.text = MyLabelText
End Set
End Property

In your content page code

dim mp as myMP = ctype(page.master, myMP)
mp.MyLabelText = "My label text"

mp.MyLabelText = "My label text"

If I am designing common code-behind functionality, but like to vary the
look and feel of my master pages I find that having the master pages
implement a standard interface is a good way to go.

That way the properties are wrapped up in one place, and the content page
code need never change because they can always access the property regardless
of the master page they reside within. e.g.

((ISomeCommonMasterPageStuff)this.Master).Title = value;

Thanks for other community members useful input.

By the way, you actually can instruct the ASP.NET page parser to generate a
strongly typed Master property in the content page by adding an @
MasterType directive:

<%@ MasterType VirtualPath="~/MasterPage.master" %>

Then you can directly use "Master.MyLabelText" to access the public
property of the master page without type cast.

However, since the Label control on the master page is protected, you still
need to wrap its Text property in a public property, like MyLabelText in
vMike's sample code.

I also think GTB's approach is better if you have several master pages.

Hope this helps. Please feel free to post here if anything is unclear.
