Hi Yuvi Yes You can achieve this using textbox enter key event. while enter key pressed  the totoal amount will be display with calculation. To do that try the enter key event code in textbox keyup event if (e.KeyChar==keys.Enter) { if ( Qty.Text!=  && BasePrice!=  ) { int baseprice=convert.Toint32( BasePrice.Text); int Qty=convert.Toint32( Qty.Text); TotalAmount.Text=Convert.ToString(baseprice*qty); } else { MessageBox.Show( Please Enter the Qty or Base Price ); } }
