private void mnuExit_Click(object sender, System.EventArgs e)
{
    if (((GrapeCity.ActiveReports.SectionReport)this.reportdesigner.Report).IsDirty == true)
    {
        MessageBox.Show("Do you want to save your report?");
    }
    else
    {
        this.Close();
    }
}
Private Sub mnuExit_Click(sender As Object, e As System.EventArgs)
	If DirectCast(Me.reportdesigner.Report, GrapeCity.ActiveReports.SectionReport).IsDirty = True Then
		MessageBox.Show("Do you want to save your report?")
	Else
		Me.Close()
	End If
End Sub
