You may have to solve this with some Javascript, so that you can trap the user when they press the Backspace Key on the keyboard.

function fOnKeypress() {

try {

var charCode = window.event.keyCode;

if (charCode == 13) {
  window.event.keyCode= 9;
}

}
catch (er) {
//alert('fOnKeypress ' + er);
}
}

You will need to load this in the BODY OnLoad event. I'm usign something like this:

var objForm= document.getElementById("aspnetForm"); // There should be a better way to get the name of the form instead of hard-coding it like this.
objForm.onkeydown=fOnKeypress;

Very easy to enable or disable a button through C#. If your page has the following button:

<asp:Button ID="Button1" runat="server" Text="Click me" onclick="Button1_Click" />

Then you can enable/disable it in your code-behind file through setting its 'enabled' property: Button1.Enabled = false; or Button1.Enabled = true Hope this helps! :) Frauke

Hope you are talking about the browser back button. You cannot disable the back button if the browser instance is opened and your URL is typed in the address bar. However you have control over the window which you are opening from your code. So the only way to solve your problem is to have a default startup page in which you have to do a opendialog for your homepage and pass the arguments disbaling the menu bars and titlebars.
