WPF 定时刷新ReportViewer显示最新数据的时候，ReportViewer页面会闪烁，有没有什么办法可以在刷新的时候避免页面闪烁？
public BookReportCtrl()
{
InitializeComponent();
this.Loaded += BookReportCtrl_load;
readDataTimer.Tick += new EventHandler(RefreshRpt);
readDataTimer.Interval = new TimeSpan(0, 0, 0, 10); //0天0时0分1秒进行刷新一次
readDataTimer.Start();
}
public void BookReportCtrl_load(object sender, RoutedEventArgs e)
{
SQLServerDB sqldb1 = new SQLServerDB();
ReportDataSource reportDataSource = new ReportDataSource();
reportDataSource.Name = "DataSet1";
reportDataSource.Value = sqldb1.ReturnTable("XXX ");
StudyReport.LocalReport.ReportPath = Directory.GetCurrentDirectory() + "\\Report\\Report1.rdlc";
this.StudyReport.LocalReport.DataSources.Clear();
StudyReport.LocalReport.DataSources.Add(reportDataSource);
StudyReport.LocalReport.Refresh();
StudyReport.RefreshReport();
}
public void RefreshRpt(object sender, EventArgs e)
{
SQLServerDB sqldb1 = new SQLServerDB();
ReportDataSource reportDataSource = new ReportDataSource();
reportDataSource.Name = "DataSet1";
reportDataSource.Value = sqldb1.ReturnTable("XXX ");
StudyReport.LocalReport.ReportPath = Directory.GetCurrentDirectory() + "\\Report\\Report1.rdlc";
this.StudyReport.LocalReport.DataSources.Clear();
StudyReport.LocalReport.DataSources.Add(reportDataSource);
StudyReport.LocalReport.Refresh();
StudyReport.RefreshReport();
}
