This question is way too ambiguous, are you talking about ASP.NET, WPF navigation, or something else? What are you expecting this back button to do, and what is it doing instead? – joshperry Dec 21 '09 at 05:01

Use can use the
to get the page that transferred control to the current page.
When you use the Transfer method or use cross-page posting to transfer processing from one ASP.NET page to another, the originating page contains request information that might be required for the destination page. You can use the PreviousPage property to access that information
If the current page is being rendered as a result of a direct request (not a transfer or cross-post from another page), the PreviousPage property contains nullNothingnullptra null reference (Nothing in Visual Basic).

One approach that can be used is to use the javascript history method:
protected void Button1_Click(object sender, EventArgs e)
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "My Unique Key", "<script>history.go(-2)</script>");
}
