ASP.NET User messages on MasterPages

Question

i have an admin master page where i want to place a label which i can control with two functions (setErrorMessage and setSuccessMessage) both functions assign strings to label's text property and change CssClass property according to function type.

I want to use these functions from nested pages while the control remains centralized on master page so i can return to form in case of error so user could edit wrong input.

How would you suggest me to do that ? either VB or C#

thanks

Answer 1

You can use below in .aspx

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

and below in your code behind,

this.Master.yourMethod 
this.Master.yourProperty 

to access your controls in child page.

Answer 2

您必须在嵌套页面中转换Master属性的类型：

((MyMasterPage)this.Master).lblMessage.Text = "Hi.";
