Hi txtDateTime.Text = DateTime.Now.ToString(); txtFinishDate.Text = null; You can use Convert.ToString() it handles null values. Just insert your value into database using the below format.. Convert.ToString( txtFinishDate.Text ); // Without Convert.ToString() you got null value error... The answer is helpful.Then please accept it ..!!
