you can check KeyPress Events cab you show the `codebehind` that you have associated with the onClick also based on the link that you provided not sure why it doesn't work for you.. did you add the `javascript code` please show all relevant code — MethodMan, Feb 06 '15 at 17:03
I tryed to add the jquery in body and before style jQuery.fn.DisableEnterKey = function() { return this.each(function() { $(this).keydown(function(e) { var key = e.charCode || e.keyCode || 0; // return false for the enter key return (key != 13); }) }) }; // You can then wire it up by just adding this code for each control: — rawan, Feb 06 '15 at 17:50

One way to do it from code behind. It will prevent the post back to the server (MSDN):

imgBtnPost.Enabled = false;

The link in your question is to disable pressing Enter key inside textbox.

Another approach is you can disable Enter Key press in an entire page. Obviously, you only want that feature in a specific page.

For example,

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
    $('form').on("keyup keypress", function (e) {
        var code = e.keyCode || e.which;
        if (code == 13) {
            e.preventDefault();
        }
    });

</script>
<asp:TextBox runat="server" ID="TextBox1"/>
<asp:ImageButton ID="imgBtnPost" runat="server"
    OnClick="ImageButton4_Click" ... />

My code works. Create a new ASPX page (without master page) and test it. The problem is if your existing ASPX page has JavaScript error, other JavaScript will stop working too. Also make sure you include jQuery library. – Win Feb 06 '15 at 18:30
