what is the best way to update status bar message?

May i know which is the best way to update a statusbar message in MDI application.I have come across this code for displaying the message in status bar of parent form from child form but i want to update the message based on user's action. In parent form

private void Form1_Load(object sender, EventArgs e)
    {
        FrmShiftManagement newMDIChild = new FrmSh开发者_StackOverflow社区iftManagement();
        newMDIChild.MdiParent = this;
        this.LayoutMdi(MdiLayout.Cascade);
        newMDIChild.Show();

        StatusMessage.Text = "Ready";

        //toolstriplabel1.Alignment = ToolStripItemAlignment.Right;
    }



 public void ShowStatus(string status)
    {
        this.StatusMessage.Text = status;
        Application.DoEvents();
    }

In Child form

((FrmTRMS)this.MdiParent).ShowStatus("Item(s) Saved");

This code is working fine when the data is saved or any action performed..Now how can i set parent form original message back to the status bar once the data is saved or deleted.

You could do this:

string oldMsg = "";
public void ShowStatus(string status)
{
    oldMsg = this.StatusMessage.Text;
    this.StatusMessage.Text = status;
    this.StatusMessage.Invalidate(); // To force status bar redraw
    this.StatusMessage.Refresh();
}

public void RestoreStatus()
{
    this.StatusMessage.Text = oldMsg;
}

and use RestoreStatus() on child form close or whenever you please.
