Setting masterpage literal results in blank output
Wondering if someone can help me out here. New to ASP.NET.
Trying to output the PageName in a masterpage.
Masterpage has a Literal in which I am setting by accessing a property on the Mast开发者_开发问答erPage "PageTitle".
<head runat="server">
<title><asp:Literal ID="litTitle" runat="server"/></title>
<asp:ContentPlaceHolder ID="head" runat="server" />
</head>
The child page is like this:
<asp:Content runat="server" ContentPlaceHolderID="content">
<%
MasterPage master = Master as MasterPage;
master.PageName = "Log in";
%>
</asp:Content>
And the property PageName is coded thusly:
private string _pageName;
public string PageName
{
get
{
return _pageName;
}
set
{
_pageName = value;
litTitle.Text = _pageName;
}
}
I'm guessing this is because the page output has already been rendered, but as I say I don't know enough about ASP.NET. I guess I'm after something similar to PHPs ob_start().
You can access the page Title from the master page code-behind as follows:
protected void Page_Load(object sender, EventArgs e)
{
string title = this.MainContent.Page.Title;
}
Note you will need to give your placeholder a name in the .Master file. If you want to retrieve the value other than the Title, do something like this: string title = (MyPage)this.MainContent.Page).MyValue;
You can find more about Master page and setting an property value in master page at below mentioned link.
