在我的C＃應用程序中，我從用戶的輸入生成一個Gridview，然後我必須給用戶一個選項來導出Gridview到Excel工作表。導出到Excel導出整個網頁，而不僅僅是gridview（啓用排序）
這是我abc.aspx頁：
<body>
<form id="form1" runat="server">
<div>
<b>Enter p1 :</b>
<asp:TextBox ID="tb_P1" runat="server" />
<br />
<b>Enter p2 :</b>
<asp:TextBox ID="tb_P2" runat="server" /><br />
<asp:Button ID="btn1" runat="server" OnClick="Button1_Click" Text="Start Search" ClientIDMode="Static" />
<asp:Button ID="btn2" runat="server" OnClick="Button2_Click" Text="Export Data to Excel" />
<hr />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true"
ShowFooter="false"
AllowSorting="true"
OnSorting="GridView1_Sorting"
EnableViewState="false"
ShowHeaderWhenEmpty="True"
AllowPaging="false">
<RowStyle Wrap="false" />
<HeaderStyle Wrap="false" />
</asp:GridView>
</div>
</form>
<br />
</body>
這裏我的.cs頁：

DataTable dt = dsldata.Tables[0];
DataView dv = new DataView(dt);
dv.Sort = sortExpression + direction;
dt = dv.ToTable();
DataSet ds1 = new DataSet("table");
ds1.Tables.Add(dt);
Session["data"] = ds1;
GridView1.DataSource = dv;
GridView1.DataBind();
}
}
我在GridView中排序啓用。 問題是：我的整個網頁都被導出到excel表單。我只希望將我的網格視圖導出。排序工作正常，我在Excel表格中獲得了新的排序表，但它與整個網頁一致。 我已經尋找在互聯網上的不同地方的解決方案。像許多人看到這個問題。我也嘗試了他們的解決方案，如 改變Response.ContentType =「application/vnd.xls」;到
Response.ContentType =「application/vnd.ms-excel」;和其他大多數解決方案都與我的ExportToExcel（）函數類似。
自從最近2天以來，我一直在使用這個東西，但是對我的應用程序來說沒有任何工作。
請幫忙！ 提前謝謝！
改變了我的ExporttoExcel功能
private void ExportToExcel(GridView GrdView, string fname)
{
try
{
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=" + fname + ".xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter stringWrite = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
}
catch (Exception ex)
{
Response.Write("<script>alert('" + ex.Message + "')</script>");
}
}
我剛剛意識到，當我在abc.aspx頁面的gridview中刪除OnSorting =「GridView1_Sorting」和AllowSorting =「true」時，我得到的只有gridview的excel表格。只有當我啓用這兩個時，問題纔會出現請幫助 ！ – Ankita
