I think you should use RegularExpressi onValidator for the same...
this will also work client side.

Hai Baby This Is only Possible in java script.........


Note:- Text Box Id======== t1


<script>
function number()

{

var num=document .getElimentById ("t1").value ;


if(num==" ")
{
alert(" Please Enter Number ");
num.focus(true) ;
num.select(true );
}


else if(isNaN(num))
{
alert("Please enter proper number ");
num.focus(true) ;
num.select(true );

}

}



Note:-- Button Propeties ===== Onclientclick ===put ==Function name


exaple:-- Onclientclick=n umber()
