Visual Studio 2008 ReportViewer控件出现了一个奇怪的问题。具体来说,当我们在页面上有一个子控件,而子控件本身承载一个报表查看器,并且报表具有文档映射时,显示/隐藏文档映射按钮上的回发似乎丢失了,因此文档映射永远不会消失。我使用了ipostbackEventHandler,似乎什么也没有得到;ReportViewer本身实现了这个接口,所以我认为我不在乎。不管怎样,代码如下:
Default.aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ReportViewerDocumentMapButtonStrippedExample._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div runat="server" id="div">
</div>
</form>
</body>
</html>
默认.aspx.cs:
using System;
namespace ReportViewerDocumentMapButtonStrippedExample {
public partial class _Default : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
}
protected override void CreateChildControls() {
base.CreateChildControls();
FindControl("div").Controls.Add(new rvControl());
}
}
}
RVCONDS.CS:
using System.Collections.Generic;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using Microsoft.Reporting.WebForms;
namespace ReportViewerDocumentMapButtonStrippedExample {
public class rvControl : HtmlGenericControl {
protected override void CreateChildControls() {
base.CreateChildControls();
var rvMain = new ReportViewer {
EnableViewState = true,
ProcessingMode = ProcessingMode.Remote,
ShowRefreshButton = false,
AsyncRendering = true,
Width = new Unit(100, UnitType.Percentage),
Height = new Unit(2000, UnitType.Pixel),
ShowCredentialPrompts = false,
ID = "viewer",
};
rvMain.ServerReport.ReportPath = "/some/report/name";
Controls.Add(rvMain);
}
}
}
有人知道这个吗?
