In Text box Design Coding:
Font-Names="Verdana" Font-Size="9pt" Height="18px" Width="190px"
MaxLength="50"></asp:TextBox>
Text box has to allow only characters:
function isNameKey(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if ((charCode <= 93 && charCode >= 65) || (charCode <= 122 && charCode >= 97){
return true;
}
else {
return false;
}
}
Text box has to allow only characters with Space:
function isNameKey(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if ((charCode <= 93 && charCode >= 65) || (charCode <= 122 && charCode >= 97) || (charCode == 32) ){
return true;
}
else {
return false;
}
}
Text box has to allow only numbers:
function isNumberKey1(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode < 48 || charCode > 57) {
return false;
}
else {
return true;
}
}
Text box has to allow only numbers with dots:
function isNumberKey(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode != 46 && (charCode < 48 || charCode > 57)) {
return false;
}
else {
return true;
}
}
