導出到Excel中的C＃錯誤

Question

我正在嘗試使用此代碼將我的面板導出到excel。

設計圖

<asp:Panel ID="ExcelPanel" runat="server" Visible="false">
    <asp:GridView ID="ExcelGridView" runat="server" AutoGenerateColumns="False" 
    Width="100%" CellPadding="3" ForeColor="#333333" GridLines="Both" ShowHeader="True" Visible="true" >   
        <Columns>
            <asp:TemplateField HeaderText="S. No." HeaderStyle-CssClass="gridViewHeader" ItemStyle-HorizontalAlign="left" SortExpression="wcName"  ItemStyle-Width="12%">
                <ItemTemplate>
                    <asp:Label ID="performanceReportTBMWCNameLabel" runat="server" Text='<%# Eval("SNo") %>' CssClass="gridViewItems"></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
</asp:Panel>

C＃代碼：

ExcelGridView.DataSource = gridviewdt;
ExcelGridView.DataBind();
ExcelPanel.Visible = true;
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=file.xls");
Response.ContentType = "application/vnd.ms-excel";

StringWriter stringWrite = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
ExcelPanel.RenderControl(htmlWrite);

Response.Write(stringWrite.ToString());

Response.Flush();
Response.End();
ExcelPanel.Visible = false;

這是我想要在我的excel文件中的區域。 但是我在excel文件中也獲得了包含母版頁的整個頁面。 如何避免整個頁面，只獲取excel文件中的面板？

Answer 1

您正在從ExcelPanel渲染HTML，因此它顯示有關該面板更改面板到GridView所有HTML，因此它將從GridView獲取HTML

更改

ExcelPanel.RenderControl(htmlWrite);

至

ExcelGridView.RenderControl(htmlWrite);
