asp.net keypress event

[berba]

I want validation for text box in a text box enter only whole numbers(no decimal). The keypress event is not available in ASP.Net. How to get key press event? Can it be done using regular expression validator? Cheers Berba

ASP.NET is serverside. You will have to use javascript. JQuery validation is a good plave to start :) --------------- stian.net

yes you can use regular expression ie) [^0-9].

You can use a MaskedEdit textbox and set the mask to only accept numbers. No validation or event handling needed.

Use a javascript/jquery function to achieve this: 1. HTML Mockup

Above, "onkeypress" is the client-side keypress event. For more accuracy, you could replace "onkeypress" with "onkeyup" which only fires when you let go of a "key" (on your keyboard). 2. Javascript/jQuery

function Validate( sender )
{
if( parseInt( sender.val() ) )
{
//proceed with the intended operation
}
else
{
alert( 'Sorry, only whole numbers are allowed in this input field. Please try again.' );
}
}
