Question

我正在尝试以zip格式导出RadGrid数据。为此，首先我以Excel格式导出数据，然后我尝试压缩它。但方法RadGrid.MasterTableView.ExportToExcel()的返回类型为void，因此我无法存储此Excel工作表的结果，以便将其作为输入传递给ZipPackage.

Answer 1

据我所知，Radgrid没有Zip导出方法。您可以做的是：在excel中导出文件，然后压缩excel文件（或您导出的任何其他类型）。我就是这样做的：

 protected void Button1_Click(object sender, EventArgs e)
{
    foreach (GridColumn col in RadGrid1.MasterTableView.Columns)
    {
        //column you may like to excluded from the export process
        if (col.UniqueName.Contains("EditCommandColumn") ||
            col.UniqueName.Contains("attachments") ||
            col.UniqueName.Contains("Upload") || col.UniqueName.Contains("Delete_col"))
        {
            col.Display = false;
        }
        else
        {
            col.Display = true;
        }

    }
    foreach (GridFilteringItem item in RadGrid1.MasterTableView.GetItems(GridItemType.FilteringItem))
        item.Visible = false;
    RadGrid1.ExportSettings.ExportOnlyData = true;
    RadGrid1.ExportSettings.FileName = "YourDesiredFileName";
    RadGrid1.MasterTableView.ExportToExcel(); //this will be exported to the folder Download
    Zip();
}

private void Zip()
{
    //here your method with your preferred library to zip the file exported from the radgrid
    //save it where you need it, rename it as you like it and delete the original excel file
}

我相信您可以尝试挂钩OnGridExporting命令然后执行类似这样的操作

   using (FileStream fs = File.Create("path you want to save the file")) {
            Byte[] info = System.Text.Encoding.Default.GetBytes(e.ExportOutput);
            //save it on the server
            fs.Write(info, 0, info.Length);
        }

将所有这些放在一个尝试中，捕获以查看文件权限问题并且文件已经存在问题。
