Dear Sir,

I use isEmpty (client-side script) to check is input box empty or not...
However, if I type a invalid value (therefore, input box is not empty anymore), the isEmpty still returns true...

              if(!dpDelivery1.isEmpty() && date1 == null)
              {
                    alert("Invalid Input");
                    return false;
              }


For my suggestion, Telerik could provide a isError function for validating input value.  That's be more easier.

Hi Jason,

The idea of the isEmpty() method is to check whether a valid date has been selected (parsed). That is why the method returns "true" if the value is invalid.

If you want to check for both valid and invalid values, please use

if (dpDelivery1.get_textBox().value == "")
{
      ........
}


All the best,
