将带有链接按钮的gridview导出到excel

Question

我有一个带有 Onclick 事件的链接按钮的 gridview 来打开一个 .pdf 文件。文件路径是在.aspx页面的Onclick事件调用的代码后面的函数下动态生成的。我可以将其导出为 excel。该列以超链接的形式出现。但我的问题是未启用 Onclick 事件，或者它没有与其余数据一起导出到 Excel 文件。

在我的 GridView（名为 GVActiveMEOs）中，我将 DataKeyNames 设置为 DataKeyNames="MEO_NR"。在asp:TemplateField 里面我有这个asp:LinkButton

<asp:linkbutton id="lnk" runat="server" onclick="OpenMEO" 
        commandargument='<%# Eval("MEO_NR") %>'
        text='<%# Eval("MEO_NR") %>'>
</asp:linkbutton>

代码隐藏

Protected Sub OpenMEO(ByVal sender As Object, ByVal e As EventArgs) 
    Dim strConnString As String = ConfigurationManager.ConnectionStrings("AEM_ESS001_DEVConnectionString").Connect‌​ionString 
    Dim con As New SqlConnection(strConnString) 
    Dim cmd As New SqlCommand 
    Dim MPath As String 
    'Dim index As Integer = GVActiveMEOs.SelectedRow.RowIndex 
    'Dim meonum As String = GVActiveMEOs.SelectedDataKey.Value 
    Dim meonum As String = DirectCast(sender, LinkButton).CommandArgument
    cmd.CommandType = CommandType.Text 
    cmd.CommandText = "Select MEOPATH from dbo.udf_GetMEOpath(@myid)" 
    cmd.Parameters.AddWithValue("@myid", meonum) 
    cmd.Connection = con 
    Try 
        con.Open() 
        MPath = cmd.ExecuteScalar() 
        'MsgBox(MPath) 
        ' Dim script As String = "window.open('" & MPath & "', 'Popup', '_newtab');"
        'Page.ClientScript.RegisterStartupScript(Me.[GetType](), "open", script, True) 
        Response.Redirect(MPath)
    End Try
End Sub

谁能帮帮我。 Rgds，苏玛

Answer 1

许多方法可以实现这一点。

1.更改asp:LinkButton标记并指定CommandName

<asp:linkbutton id="lnk" runat="server" onclick="OpenMEO" 
        commandargument='<%# Eval("MEO_NR") %>'
        commandname="Select"
        text='<%# Eval("MEO_NR") %>'>
</asp:linkbutton>

2.创建RowCommandEvent

标记

OnRowCommand="GVActiveMEOs_OnRowCommand" 

代码隐藏

Protected Sub gridview1_RowCommand(sender As Object, e As GridViewCommandEventArgs)
    'custom code
    Dim meonum As String = DirectCast(e.CommandSource, LinkButton).CommandArgument
    'custom code
End Sub

永远记住，点击的行不是SelectedRow，除非你将CommandName指定为CommandName="Select"
