Solution 1

Instead of Img Button.. Check is textbox is empty or not..

if((TextBox1.Text==string.Empty) || TextBox2.Text==string.Empty))

If you use && then the message will show only when both are empty
but requirement is any one if empty.

SQL

if(DOB.SelectedDateValue.ToString()=="" || Wedding.SelectedDateValue.ToString()== "")
{
LblErr.Text = "Date of birth or wedding date is not selected";
return;
}

Initially what do you have in this control?
DOB.ToString()

You can always compare what is in the control currently with the current computer date.

So if the

C#

DOB.ToString()==ComputerDate.string()
            {
             //then it means person haven't selected the wedding date
             //throw you error message
            }

This is just the logic on how to check if the control is clicked by checking change.
