gridcontrol导出报表
gridcontrol点击导出excel数据导出来。然后点击保存按钮。怎么弹出对话框让用户选择路径进行保存
------解决方案--------------------
导出时用一个saveFileDialog,将选择路径传到下面方法就可以了     
 public static void ExportPurchaseProductExcel(DataTable table, string templetPath, string savePath)
       {
导出时加上这句代码
           File.Copy(templetPath, savePath, true);//模版路径,保存路径
           _Excel.Application app = new _Excel.ApplicationClass();
           app.Visible = false;
           _Excel.Workbook book = app.Workbooks.Open(savePath, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing, System.Type.Missing);
           _Excel.Worksheet sheet = (_Excel.Worksheet)book.ActiveSheet;
