 DialogResult dialogResult = MessageBox.Show("record saved", "requisition", MessageBoxButtons.OK, MessageBoxIcon.Information);
            if (dialogResult == DialogResult.OK)
            {

                frmmain main = new frmmain();
                main.Show();

                frmrequisition requisition = new frmrequisition();
                requisition.Close();
            }

            else

                MessageBox.Show("error", "requisition", MessageBoxButtons.OK, MessageBoxIcon.Error);

                }

}

Answer 1

You are creating a new instance of the requisition form, and calling the close method on that instance:

frmrequisition requisition = new frmrequisition();
requisition.Close();

You should close the requisition that was being displayed. Have you tried this.Close(), assuming the event handler is part of the requisition form?

Answer 2

Your creating a new object and closing that. you need to have a reference to your frmrequisition that is currently displayed.
