Have you tried the rangeValidators available for Asp.Net ?

you cant have a seperate keypress event for web pages.. unless you want to use ajax.

You could use the editvaluchanged event, but that will cause a lot of postbacks and will highly affect the performance.

Use javascript


function RestrictKeys(ev t)
{
var e=evt ? evt : window.event;

var key =e.charCode;
if ((key ==126) ||(key==124)&&( key!=8))
{
return false;
}
else
return true;
}
