Correct Date Format Validation of a Date

Label gdate=(Label)(GridView1.Rows[i].FindControl("Date"));

Now what i want is to make sure that the date(or value) in variable gdate is a valid date(ShortDate like 14-03-2014) without time (not like 14-03-2014 00:00:00 which is invalid)

Try this one to store formated date

string chkin = txtCheckIn.Text;
DateTime CheckIn = DateTime.ParseExact(chkin, "MM/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture);

gdate.Text = DateTime.Now.Date.ToShortDateString();

Use DateTime TryParseEaxct if the exact format needs checking:

DateTime dateValue
if (DateTime.TryParseExact(gdate.Text, "dd-MM-yyyy", null, 
                       DateTimeStyles.None, out dateValue))
{
    //Date in correct format
    //use dateValue
}
else
{
    //Date in incorrect format
}

Convert.ToDateTime will throw an exception if the datetime cannot be parsed.

ParseExact will also throw an exception if the date string in your Date control is empty.

You can use short date function for date format, like

 DateTime dt=new DateTime();
 dt = DateTime.Now;
 MessageBox.Show(dt.ToShortDateString());

A CustomValidator here:

<asp:CustomValidator runat="server"
    ID="valDateRange" 
    ControlToValidate="txtDatecompleted"
    onservervalidate="valDateRange_ServerValidate" 
    ErrorMessage="enter valid date" />

Server Side:

protected void valDateRange_ServerValidate(object source, ServerValidateEventArgs args)
{
    DateTime minDate = DateTime.Parse("1000/12/28");
    DateTime maxDate = DateTime.Parse("9999/12/28");
    DateTime dt;

    args.IsValid = (DateTime.TryParse(args.Value, out dt) 
                    && dt <= maxDate 
                    && dt >= minDate);
}
