ReportViewer : RDLC自定义工具栏

RDLC自定义工具栏:
既然我们使用这种方法进行报表的打印，那么Visual Studio的控件ReportViewer的工具栏就不再符合我们的要求了。因为这个报表浏览器的工具栏上的按钮虽然可以设置属性显示或隐藏其中的一部分，但是我们却不能自己往这个工具栏上添加按钮（显然，我们需要实现自己的页面设置、预览和打印按钮），在这一点上，建议Microsoft将工具栏和报表浏览器分离，应该做得和BindingNavigator那样就好了。
我们先设置ReportViewer控件的ShowToolBar方法为false，然后在ReportViewer控件纸上添加除页面设置、预览、打印外的应该有的按钮，像刷新、终止、导出、缩放、搜索、导航等，这些按钮的Click事件定义如下：
/// <summary>

GetTimeStamp()
{ string strRet = string.Empty; System.DateTime dtNow = Pub.DateTimeEx.ServerTime; strRet += dtNow.Year.ToString() + dtNow.Month.ToString("00") + dtNow.Day.ToString("00") + dtNow.Hour.ToString("00") + dtNow.Minute.ToString("00") + dtNow.Second.ToString("00") + System.DateTime.Now.Millisecond.ToString("000"); return strRet; }

{ fs.Write(bytes, 0, bytes.Length);
} if (Pub.WinForm.Msg.Question("报表打印： \r\n 成功导出Excel文件！" + strFilePath + "\r\n 要现在打开文件" + strFilePath + "吗？") == DialogResult.Yes) { System.Diagnostics.Process.Start(strFilePath); } }
