function textAlphanumeric(obj, evt1) {
var ctrl = obj.id;
var charCode1 = (evt1.which) ? evt1.which : event.keyCode
if ((charCode1 >= 48 && charCode1 <= 57) || (charCode1 >= 65 && charCode1 <= 90) || (charCode1 >= 97 && charCode1 <= 122) || (charCode1 == 8) || (charCode1 == 32)) {
return true;
}
else {
// alert("Please enter alpha-numeric only");
ShowPopupMessage('Please enter alpha-numeric only', ctrl);
//$('#' + ctrl).focus();
//$('#' + ctrl).val('');
// return false;
}
}
We can call this function like below.
TextBox txta -=new TextBox();
txta is a dynamically TextBox.
txta.Attributes.Add("onkeypress", "return textAlphanumeric(this,event)");
var ctrl = obj.id;
var charCode1 = (evt1.which) ? evt1.which : event.keyCode
if ((charCode1 >= 48 && charCode1 <= 57) || (charCode1 >= 65 && charCode1 <= 90) || (charCode1 >= 97 && charCode1 <= 122) || (charCode1 == 8) || (charCode1 == 32)) {
return true;
}
else {
// alert("Please enter alpha-numeric only");
ShowPopupMessage('Please enter alpha-numeric only', ctrl);
//$('#' + ctrl).focus();
//$('#' + ctrl).val('');
// return false;
}
}
