将多个 ASPxGridView 导出到具有不同工作表的 Excel

Question

我在不同的选项卡中使用了 2 个不同的 ASPxGridView。我想在同一个 excel 文件中导出这些具有不同 sheet 的 ASPxGridView。

我可以在 1 excel 和 1 sheet.

中导出多个 ASPxGridView

protected void ExportButton_Click(object sender, EventArgs e)
{
    PrintingSystem ps = new PrintingSystem();

    PrintableComponentLink link1 = new PrintableComponentLink(ps);
    link1.Component = GridExporter1;

    PrintableComponentLink link2 = new PrintableComponentLink(ps);
    link2.Component = GridExporter2;

    CompositeLink compositeLink = new CompositeLink(ps);
    compositeLink.Links.AddRange(new object[] { link1, link2 });

    compositeLink.CreateDocument();
    using (MemoryStream stream = new MemoryStream())
    {
        compositeLink.PrintingSystem.ExportToXls(stream);
        WriteToResponse("filename", true, "xls", stream);
    }
    ps.Dispose();

}
void WriteToResponse(string fileName, bool saveAsFile, string fileFormat, MemoryStream stream)
{
    if (Page == null || Page.Response == null)
        return;

    string disposition = saveAsFile ? "attachment" : "inline";
    Page.Response.Clear();
    Page.Response.Buffer = false;
    Page.Response.AppendHeader("Content-Type", string.Format("application/{0}", fileFormat));
    Page.Response.AppendHeader("Content-Transfer-Encoding", "binary");
    Page.Response.AppendHeader("Content-Disposition",string.Format("{0}; filename={1}.{2}", disposition, fileName, fileFormat));
    Page.Response.BinaryWrite(stream.GetBuffer());
    Page.Response.End();
}

这是我的商品：

<dx:ASPxGridView ID="ASPxGridView1" runat="server" Theme="DevEx">
    <Settings ShowGroupPanel="True" />
    <SettingsPager PageSize="15" />
</dx:ASPxGridView>

<dx:ASPxGridView ID="ASPxGridView2" runat="server" Theme="Office2010Silver">
</dx:ASPxGridView>

<dx:ASPxButton ID="ExportButton" runat="server" Text="Export both grids" Width="205px" OnClick="ExportButton_Click" />

<dx:ASPxGridViewExporter ID="GridExporter1" runat="server" GridViewID="ASPxGridView1" />

<dx:ASPxGridViewExporter ID="GridExporter2" runat="server" GridViewID="ASPxGridView2" /><br />

您必须指定要导出的导出模式

语法

public XlsExportMode ExportMode { get; set; }

XlsExportMode An XlsExportMode enumeration value, representing the XLS export mode. The default is XlsExportMode.SingleFile.

各种模式有：

Name                     Description
DifferentFiles           A document is exported to multiple files, page-by-page. In this mode every document page is exported to a single XLSX file.
SingleFile               A document is exported to a single file. Note that in this mode, page headers and footers are added to the resulting XLSX file only once, at the beginning and at the end of the document.
SingleFilePageByPage     A document is exported to a single file, page-by-page. In this mode, each page is exported to an individual sheet of the same XLSX file.

所以你可以这样做：

 using (MemoryStream stream = new MemoryStream())
    {
        XlsExportOptions options = new XlsExportOptions();
        options.ExportMode = XlsExportOptions.SingleFilePageByPage;
        compositeLink.PrintingSystemBase.ExportToXls(stream, options);
        WriteToResponse("filename", true, "xls", stream);
    }
