How to disable Enter key pressed inside TextBox to avoid submission or Postback through code behind?

Visual Studio gives us a warning message when we add onkeydown event.But it's just a warning so we can ignore.So to avoid this warning,we can also disable submission from code behind as:-

txt_emp_first_name.Attributes.Add("onkeydown","return (event.keyCode!=13);");

//OR

txt_emp_first_name.Attributes.Add("onkeydown","prevent_submission();");

Above return code should be written inside prevent_submission() js function.

How to disable the Enter key pressed form post-back for all page controls?

Simply add below code in the body tag as:

<body onkeydown = "return (event.keyCode!=13);">

Then it will be disabled for all controls on the page.
