How to change master page value from child page.

Question

I want to change master page some label value from child page.

Answer 1

See the post: http://stackoverflow.com/questions/2370891/how-to-update-a-div-tag-in-master-page-using-a-button-click-in-content-page-or-w/2370936#2370936

Answer 2

Create a property like this in master page:

public string MyText { get {return lbl.Text;} set {lbl.Text = value;}}

Once you do that you can use the same property in content page like:

((MasterPageTypeName)Page.MasterPage ).MyText = "test";

and you are done!

Answer 3

Or you can just add '@mastertype' to the child page .aspx declaratively. This creates a strongly-typed reference to the masterpage.

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

Answer 4

Everything is fine,just need to change:

((MasterPageTypeName)Page.MasterPage ).MyText = "test";

to ((MasterPageTypeName)Page.Master ).MyText = "test";

that's it,you are done.
