Question

我正在尝试将GridView导出到Excel。

我试图按照此处的步骤进行操作：

http://www.programming-free.com/2012/09/aspnet-export-grid-view-to-excel.html#.UhUREpK1F9o
export gridview to excel file

和其他类似的网站。

我的GridView没有任何与默认属性不同的特殊属性如果这很重要，我的SqlDataSource会使用filterExpression。

当我尝试上面提到的解决方案时，没有异常发生，但是excel 没有生产。

更新

我忘了提及GridView位于asp:Content控件内。我听说这可能很重要。

我的代码隐藏是这样的（我尝试过多种方法）。

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = String.Empty;
EnableViewState = false;
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView3.RenderControl(htmlWrite);

Response.Write(stringWrite.ToString());         
HttpContext.Current.ApplicationInstance.CompleteRequest();

您可以在后面的代码上创建GridView并单独选择数据并按如下方式导出Gridview。所以你不必担心页面上的Gridview。

Dim GridView1 As New GridView

SqlDataSource1.SelectCommand = "SELECT * FROM TableName"
GridView1.DataSource = SqlDataSource1
GridView1.DataBind()

Response.Clear()
Response.Buffer = True
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
Me.EnableViewState = False
Dim oStringWriter As New System.IO.StringWriter
Dim oHtmlTextWriter As New System.Web.UI.HtmlTextWriter(oStringWriter)

GridView1.RenderControl(oHtmlTextWriter)

Response.Write(oStringWriter.ToString())
Response.End()
