Validation for calender control of RadDatePicker (Telerik Controls)

Question

I want to validate the RadDatePicker when a date is selected. User should not select greater than a particular date ? How can I restrict user from selecting a date which is not greater than a particular date.

Particular date populated from the database.

Answer 1

You can use CompareValidator Control.Just note to compare to your date (ValueToCompare) instead of (ControlToCompare) and set the type. By default it's string as i remember.so you need to set it to Date.Also look to this page.

Answer 2

On your other question:

How can I restrict user from selecting a date which is not greater than a particular date.

In C#:

RadDatePicker1.MaxDate = myMaxDateTimeVariable;

or client-side:

var radDatePicker1 = $find("<%= RadDatePicker1.ClientID %>");
radDatePicker1.set_maxDate(myMaxDate);
