Hi Narayanan,

We get the same output from the following simple code...

//Method Calling 

if(!CheckIsNumeric(txtInput.Text))

{

    txtInput.Text = string.Empty;

}



private bool CheckIsNumeric(string sText)

        {

            try

            {

                if (int.Parse(sText.Trim()) > 24)

                {

                    //MessageBox.Show("Please enter less than 24");

                    return false;

                }

                else

                    return true;

            }

            catch

            {

                //MessageBox.Show("Please enter numeric value only");

                return false;

            }

        }
