Try like below:

DateTime dateTimeObj = DateTime.ParseExact(tbxFromDate.Value, "dd/MM/yyyy", CultureInfo.InvariantCulture);
if (tbxFromDate.Value != "" && dateTimeObj > DateTime.Today)
{
Messagebox.Show("From Date should be earlier or equal To Today Date", MessageHelper.MessageType.Warning);
}

Accepted

Hi Raja,

You have to parse the date value before validation. Use the below code:

DateTime date = DateTime.ParseExact(this.myTextBox.Text, "dd/MM/yyyy", null);

Here you can send the text value entered by the user or a value picked up from your datePicker control. The next key thing is to format your Date to be parsed and if time doesn't bother you, pass the "null" value.

Hope this helps.
