Change the text value in a control in a Master page

Andrew

Hello,

I have a header user control (.ascx) in a Master Page that I want to change the text of by the individual page.

I haven't seemed to be able to reference it directly to change the text.

If I set the control with a global property, how to I reference it from the page since they are in 2 different sections of the Master page?

Thanks.

Accepted answer
Provide a public method in your MasterPage that sets the title, for example:
public void setTitle(string title)
{
    this.LblTitle.Text = title;
}
Then you can call it from your UserControl(YourMasterPage is the actual type of the MasterPage):
((YourMasterPage)this.Page.Master).setTitle("new Title");

Thanks Manikanadan! I did manage to get it after finding some information doing basically what you described.

I made the header control contain a public string property and on page load it populates the text with the variable.
public string Page_Header_Text { get; set; }

protected void Page_Load(object sender, EventArgs e) {
    hlHeader.Text = Page_Header_Text;
}
Then on the Master page I made a public string for the page to edit and on Page_Load I set the header control's public variable with whatever the Master Page's variable is set to
public string Page_Header_Display = "Default Header Text";

protected void Page_Load(object sender, EventArgs e) {
    page_header.Page_Header_Text = Page_Header_Display;
}
And then the key, which is what I also see you have in your response, is being able to call the master page's variable which includes adding this to the .aspx page.

<%@ MasterType VirtualPath="~/Portal.Master" %>
and then in the .aspx.cs page set the variable
Master.Page_Header_Display = "Text for Current Page";
But I think I will try what you have down if it skips me needing to add the piece at the top of the .aspx page and just put it in the .cs file.
