Solution 1

Please use Range validator control to check the things. You can get the code to find the solution.

Client Side:

XML

<asp:TextBox ID="txtDate" runat="server" />
        <asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="txtDate"  Type="Date" ErrorMessage="Please enter 15 years back date from the current date." />

Server Side:

C#

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            {
                RangeValidator1.MinimumValue = DateTime.Now.AddYears(-100).ToShortDateString();
                RangeValidator1.MaximumValue = DateTime.Now.AddYears(-15).ToShortDateString();
            }
        }

Dear you need to change the date format. My solution is based on mm/dd/yyyy format. Let me know if you need more information.

Solution 2

Try something like:

C#

DateTime enteredDate = Convert.ToDate(txtBox.Text);
DateTime currentDate = DateTime.Now;

TimeSpan diffResult = currentDate.Subtract(enteredDate);
int years = (int) (diffResult.Days / 365.25); // leap year considered
if (years >= 15)  //if difference greater than 15 years
{
    // do your stuff 
}

Date format matters. You need to debug and see why it is so.
