Hi Kiran, In the Page Load Event, You can set the RangeValidator Property to the current year. Something like this, RangeValidator1.MaximumValue = DateTime.Now.Year.ToString(); Thanks, Shankar M

Fine Kiran, Then, you can use the Server Control Range Validator. Here it is. You can use the ControlToValidate property to set the TextBox that need to be validated, and by specifying the Min and Max value. asp : RangeValidator ID ="RangeValidator1" runat ="server" ControlToValidate ="txtFiche" MinimumValue ="1940" MaximumValue = "2013" ErrorMessage ="Invalid Input"> asp : RangeValidator > Thanks, Shankar M
