Question

我正在asp.net上做一个项目

我使用Devexpress gridview 9.1。

我想在按钮点击时打印 gridview only 。基本上页面中没有其他控件。

我发现，这可以通过将网格传递到下一页并在那里打印来实现。但我的要求不允许这样做。

所以可以通过任何方式在同一页上单独打印 gridview吗？

Answer 1

为此目的使用stanalone ASPxGridViewExporter组件：

 protected void ASPxButton1_Click(object sender, EventArgs e)
        {
            using(MemoryStream ms = new MemoryStream()){
                PrintableComponentLink pcl = new PrintableComponentLink(new PrintingSystem());
                pcl.Component = ASPxGridViewExporter1;
                pcl.Margins.Left = pcl.Margins.Right = 50;
                pcl.Landscape = true;
                pcl.CreateDocument(false);
                pcl.PrintingSystem.Document.AutoFitToPagesWidth = 1;
                pcl.ExportToPdf(ms);
                WriteResponse(this.Response, ms.ToArray(), System.Net.Mime.DispositionTypeNames.Inline.ToString());
            }
        }
        public static void WriteResponse(HttpResponse response, byte[] filearray, string type)
        {
            response.ClearContent();
            response.Buffer = true;
            response.Cache.SetCacheability(HttpCacheability.Private);
            response.ContentType = "application/pdf";
            ContentDisposition contentDisposition = new ContentDisposition();
            contentDisposition.FileName = "test.pdf";
            contentDisposition.DispositionType = type;
            response.AddHeader("Content-Disposition", contentDisposition.ToString());
            response.BinaryWrite(filearray);
            HttpContext.Current.ApplicationInstance.CompleteRequest();
            try
            {
                response.End();
            }
            catch (System.Threading.ThreadAbortException)
            {
            }

        }

从页面打印Devexpress网格？
