Try
btnSearchEmpNo.Enabled = False[code].....
Now I wanna set when user click on this button to delete a employee (for example) then the datagrid that i have in my application will not show the data of the deleted employee but in the background, the employee haven't been deleted from database.The employee only will be deleted from database when the user click on SAVE button.I know this application have to use RowState but how?
