Hi Nilesh  You can validate the E-mail Id in Datagridview's CellValidatingEvent Something like this Presume that dgv is the name of the DataGridview and MailId is one of the column of Datagridview. string HeaderText = dgv.Columns[e.ColumnIndex].HeaderText; This is to get the header Text of the Column to check that we are in the E-mail id column. if (! HeaderText .Equals(MailId)) return; Abort validation if the cell is not MailId column. if(string.IsNullOrEmpty( e.FormattedValue.ToString())) { MessageBox.Show(Please Enter the mail Id); e.Cancel = true; // Will not allow us to Leave the cell until an non-empty string is entered. } You can also use Regular Expressions to validate that the E-Mail Id entered is Valid.
