Question

Disable Return key outside textareas on a Asp.Net web page (containing ajax code)

Answer 1

A:

You could achieve it by using Panel like below.

 <asp:Panel runat="server" DefaultButton="">
other html/asp tags
    </asp:Panel>

There should be other efficient ways.

Here is some script I put together yesterday night but was not able to post it as my laptop ran out of battery :(

NOTE: I'm using jQuery for it. But you can easily re-write it to work with pure javascript.

<html>
<head>
<title>Enter Key</title>
<script src="jquery-1.2.6.js"></script>
</head>
<body>
<div id="prompt" style="color:#eeffee;width:50px;height:50px;"></div>
<textarea id="txt" cols="25" rows="10"></textarea>
<script type="text/javascript">
$(document).ready(function(){
    var ar=$("textarea").add($("input"));
    var elems=new Array();
    var key = 13;

    $(ar).each(function(){
     var i=$(this).attr("id");
     if(i && i!=="")
      elems.push(i);
    });
    elems.sort();

    $().keypress(function(e){
     var k=e.keycode || e.which;
     var id = e.target.id;
     if(k === key){
      if(id){
       var ar=$.grep(elems,function(a){ return a==id;});
       if(ar.length === 0){
        $("#prompt").html("Eating ");
          return false;
       }else{
        $("#prompt").html("Allowed");
       }    
      }else{
       $("#prompt").html("Eating ");
          return false;
      }   
     }
    });
});
</script>
</body>
</html>

A:

Here is what I used to fix this problem.

<form runat="server" defaultbutton="DoNothing">
        <asp:Button ID="DoNothing" runat="server" Enabled="false" style="display: none;" />
