Preserving Value Types
The following code demonstrates how to insert a DateTime value on the server side into the control’s value collection:
ASPxHiddenField1["myBirthDay"] = new DateTime(1985, 8, 29);
On the client side, you can access and modify this value as a Date object:
var date = ASPxHiddenField1.Get("myBirthDay"); date.setHours(15, 23); // You can manipulate the obtained value as a date value. ASPxHiddenField1.Set("myBirthDay", date);
On the server side, you can again manipulate this value as a DateTime object:
DateTime date = (DateTime)ASPxHiddenField1["myBirthDay"]; int hour = date.Hour; // This value is 15.
