Hi all,
I have created a simple template class as follow, but i encountered memory
leakage on the base.Render(writer). Have all you of encountered the same
problem?


using System;
using System.Web.UI;
public class PageBase : System.Web.UI.Page
{
private string _pageTitle;
public string PageTitle
{
get { return _pageTitle; }
set { _pageTitle = value; }
}

protected override void Render(HtmlTextWriter writer)
{
// First we will build up the html document,
// the head section and the body section.
writer.Write( @"
<html>
<head>
<title>" + PageTitle + @"</title>
</head>
<body>" );

// Then we allow the base class to render the
// controls contained in the ASPX file.
base.Render( writer );

// Finally we render the final tags to close
// the document.
Writer.Write( @"
</body>
</html>" );
}
}
 
Boy,
Just from looking at your code, I can't see how you are experiencing a
memory leak in that method. Omit that method and test again to see about
the memory usage. The memory problem is likely elsewhere.

Hi Jeffrey,

Thank you for your reply.

I have used a software
(http://www.compuware.com/products/devpartner/default.htm) to monitor
performance of my application.
The software found that there is memory leakge at that point. i.e. the line
"base.render(writer)".

I missed something in last post. The whole program should be as follows:


using System;
using System.Web.UI;
public class PageBase : System.Web.UI.Page
{
private string _pageTitle;
public string PageTitle
{
get { return _pageTitle; }
set { _pageTitle = value; }
}

}




public class ChildClass: PageBase{

protected override void Render(HtmlTextWriter writer)
{
// First we will build up the html document,
// the head section and the body section.
writer.Write( @"
<html>
<head>
<title>" + PageTitle + @"</title>
</head>
<body>" );

// Then we allow the base class to render the
// controls contained in the ASPX file.
base.Render( writer );

// Finally we render the final tags to close
// the document.
Writer.Write( @"
</body>
</html>" );
}

}
