DEV导出多个控件到excel

代码如下

//title文件名，isPageForEachLink是分成多个工作薄，sheetName工作薄名，cll容器
ExportToExcel("维修率统计图", true, "",groupBox1);

public void ExportToExcel(string title, bool isPageForEachLink, string sheetName, Control cll)
        {
            SaveFileDialog saveFileDialog = new SaveFileDialog()
            {
                FileName = title,
                Title = "导出Excel",
                Filter = "Excel文件(*.xlsx)|*.xlsx|Excel文件(*.xls)|*.xls"
            };
            DialogResult dialogResult = saveFileDialog.ShowDialog();
            if (dialogResult == DialogResult.Cancel)
                return;
            string FileName = saveFileDialog.FileName;
            DevExpress.XtraPrintingLinks.CompositeLink link = new DevExpress.XtraPrintingLinks.CompositeLink(new DevExpress.XtraPrinting.PrintingSystem());

            foreach (ChartControl item in cll.Controls)
            {
                var plink = new DevExpress.XtraPrinting.PrintableComponentLink() { Component = item };
                link.Links.Add(plink);
            }

            if (isPageForEachLink)//15.1 的Xls不支持这个功能，15.2未知
                link.CreatePageForEachLink();
            if (string.IsNullOrEmpty(sheetName)) sheetName = "Sheet";//默认工作薄名称
