can you tell, what is the value you are getting and value after rounding off. And what is the value displays in textbox after round off.

okay then check the following, did you enabled again the textbox ? is there any errors in browser side ? with the help of inspect element check that in browser ! then kindly let me know what's the error. I will guide you.

Sundar actually I tried yesterday I get the value in textbox and round off the value but I can't able to assign the round off value again to that same textbox that is big problem

I will share the Logic, please try, In the Textbox blur event call the JavaScript Function to Round Off the value. After its done then make the textbox disabled. JavaScript fuction to round is available in google. Search. If you did not get let me know.

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.
