Due to some reasons (like don’t allow to enter chars in Price TextBox), we restrict users to enter chars in TextBox. We can implement this functionality by using below method.
<script type="text/javascript"> function checkNumeric(event) { var kCode = event.keyCode || event.charCode; // for cross browser check //FF and Safari use e.charCode, while IE use e.keyCode that returns the ASCII value if ((kCode > 57 || kCode < 48) && (kCode != 46 && kCode != 45)) { //code for IE if (window.ActiveXObject) { event.keyCode = 0 return false; } else { event.charCode= 0 } } } </script> <asp:TextBox ID="TextBox1" runat="server" onkeypress="return checkNumeric(event); ></asp:TextBox>
