Solution 1

The backspace key is a default browser behaviour which is the same as clicking the back button.

Although that behaviour is overwritten when a textbox has focus. Are you sure the textbox has focus when you're hitting the backspace key?

If the textbox does has focus, then there will be a scripted behaviour change using the onkeypress event within your page.

You can achive this using java script

<asp:TextBox ID="TextBox1" runat="server" onKeyDown="preventBackspace();
"></asp:TextBox>

and the script looks like this:

XML

<script type="text/javascript">
            function preventBackspace(e) {
                var evt = e || window.event;
                if (evt) {
                    var keyCode = evt.charCode || evt.keyCode;
                    if (keyCode === 8) {
                        if (evt.preventDefault) {
                            evt.preventDefault();
                        }
                        else {
                            evt.returnValue = false;
                        }
                    }
                }
            }
        </script>
