Hi Dorababu,

I suppose you want to calculate the year difference between two dates. Try the following code snippet.

ASPX:

<telerik:RadDatePicker ID="picker1" runat="server"></telerik:RadDatePicker>
<telerik:RadDatePicker ID="picker2" runat="server"></telerik:RadDatePicker>
<asp:Button ID="btn1" runat="server" onclick="btn1_Click" />

C#:

protected void btn1_Click(object sender, EventArgs e)
    {
        DateTime dt1 = picker1.SelectedDate.Value;
        DateTime dt2 = picker2.SelectedDate.Value;
        int t=dt1.Year - dt2.Year;
        if (t < 18)
        {
            Response.Write("age is less than 18");
        }
        else
            Response.Write("age is greater than 18");
    }

Hope this helps.

Thanks,
Princy.
