水晶报表工具栏中的按钮问题 [英] Problem with button in crystal report toolbar

问题描述

先生您好，

我正在处理水晶报表.我使用以下代码在Crystal Report工具栏上创建了一个按钮:

Hello sir,

I am working with crystal reports. I created a button on crystal report toolbar using the following code:

reportDocument = (ReportDocument)Session["reportDocument"];
       CrystalReportViewer1.ReportSource = reportDocument;
        System.Web.UI.Control oControl = CrystalReportViewer1.Controls[2];
        //Button oButton = new Button();
        //oButton.ID = "newButton";
        //oButton.Text = "My New Button";
        //oControl.Controls.Add(oButton);
        ImageButton BtnExport = new ImageButton();
        BtnExport.ID = "BtnExport";
        BtnExport.ImageUrl = "~/images/xls.png";
        // BtnExport.ToolTip = "Zoom";
        BtnExport.Click += ImgBtnXls_Click;
        BtnExport.EnableViewState = true;
        oControl.Controls.Add(BtnExport);
        UpdatePanel UpdatePanel1 = new UpdatePanel();

        System.Web.UI.PostBackTrigger trigger = new System.Web.UI.PostBackTrigger();

        trigger.ControlID = BtnExport.UniqueID.ToString();
        UpdatePanel1.Triggers.Add(trigger);

我的问题是，每当我单击按钮以导出报告时，它都会显示如下错误:

My problem is whenever I click the button to export the report, it shows an error like below:

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near ''�ࡱ�''.

如果有人知道原因，请帮助我.

If anyone knows the reason, please help me.

推荐答案

为您的UpdatePanel中的按钮 BtnExport 添加一个PostBackTrigger.就这样.

Add a PostBackTrigger to your UpdatePanel for the button BtnExport. That''s all.

<Triggers>
<asp:PostBackTrigger ControlID="BtnExport" />
</Triggers>
