Question

我在“更新”面板中有一个网格视图。 grid-view中有一个链接按钮，它在行命令事件中触发导出命令。还有一个网格视图可以在此命令代码中导出。我调试，指针进入，但导出没有发生。我知道我在这里遗漏了一些东西，但是在花了很多时间后却无法得到它。脚本管理器位于母版页上。

请任何人帮忙。以下是代码。

以下是行命令事件

的代码

 If e.CommandName = "download" Then
        Dim str As String
        str = " select * FROM [Box] where   MsgId='" + e.CommandArgument + "'"
        Dim com As New SqlCommand(str, con)
        Dim da As New SqlDataAdapter(com)
        Dim dt As New DataTable
        da.Fill(dt)

        If Not dt Is Nothing Then
            If dt.Rows.Count > 0 Then
                grd_export.DataSource = dt
                grd_export.DataBind()
                grd_export.Visible = True
                Response.Clear()
                Response.Cache.SetCacheability(HttpCacheability.NoCache)
                Response.AddHeader("content-disposition", "attachment;filename=Message.xls")
                Response.Charset = ""
                Response.ContentType = "application/vnd.xls"
                Me.EnableViewState = False
                Dim stringwrite As System.IO.StringWriter = New System.IO.StringWriter
                Dim htmlwrite As System.Web.UI.HtmlTextWriter = New System.Web.UI.HtmlTextWriter(stringwrite)
                grd_export.RenderControl(htmlwrite)
                Response.Write(stringwrite.ToString())
                grd_export.Visible = False
                Response.End()


            End If
        End If

    End If

您需要在postback trigger update panel添加respose.write才能使用import {bootstrap} from 'angular2/platform/browser'; import {Component, View} from 'angular2/core'; @Component({ })。

导出gridview到excel不能使用Ajax和Update面板
