ReportViewer导出功能筛选

ReportViewer只能导出Excel，把导出Word和PDF功能去掉

 

 <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana" Font-Size="8pt"
                InteractiveDeviceInfos="(集合)" WaitMessageFont-Names="Verdana" WaitMessageFont-Size="14pt"
                Width="100%" Height="100%" ShowToolBar="true" ShowBackButton="False" ShowFindControls="False"
                ShowRefreshButton="False" HyperlinkTarget="_self" 
                InteractivityPostBackMode="AlwaysSynchronous" 
                onprerender="ReportViewer1_PreRender">
            </rsweb:ReportViewer>

        protected void ReportViewer1_PreRender(object sender, EventArgs e)
        {
　　　　　　　　foreach (RenderingExtension extension in ReportViewer1.LocalReport.ListRenderingExtensions())
            {
                if (extension.Name == "IMAGE" || extension.Name == "WORD"|| extension.Name == "PDF")
                {
                    FieldInfo fi = extension.GetType().GetField("m_isVisible", BindingFlags.Instance | BindingFlags.NonPublic);
                    fi.SetValue(extension, false);
                }
            }  
　　　　}
