hi in this post i will show how to validate and allow only float,integer,decimal values in asp.net textbox.
Example:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script language="javascript" type="text/javascript" >
$(document).ready(function () {
$("#<%= TextBox1.ClientID %>").keypress(function (event) {
if (event.which < 46 || event.which > 59) {
event.preventDefault();
} // prevent if not number/dot
if (event.which == 46 && $(this).val().indexOf('.') != -1) {
event.preventDefault();
} // prevent if already dot
});
});
</script>
