Solution 4

By using RegularExpressionValidator you can make it work

Set the ValidationExpression ='^[^\"]*$' to restrict quotes input.

Refer similar discussion on CP: Validation of a textbox to prevent quotation marks to be used[^]

Solution 1

C#

<html>
<head>
	<script type="text/javascript" language="javascript">
		function checkQuote() {
			if(event.keyCode == 39) {
				event.keyCode = 0;
				return false;
			}
		}
	</script>
</head>
<body>
	<input type="text" onkeypress="return checkQuote();" />
</body>
</html>

Reason for my vote of 2: you validate the text box at client-side. But ALWAYS validate stuff at server-side. If someone disables JavaScript in his browser, then you don't longer validate the textbox.

Hey Mukesh.. you said that if we could put the "" in Valid Chars than that will be restricted??????

ON the other side I think that this tag is used to describe the valid characters which you wana allow in your fields.... is not so???
