Hi guy,

I tried export data to excel and csv by the following code.

In the C# code
[DirectMethod]
        public void DownloadFile(string type)
        {
            string json = GridData.Value.ToString();
            StoreSubmitDataEventArgs eSubmit = new StoreSubmitDataEventArgs(json, null);
            System.Xml.XmlNode xml = eSubmit.Xml;

            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.Clear();
            switch (type)
            {
                case "Excel":
                    response.ContentType = "application/vnd.ms-excel";
                    response.AddHeader("Content-Disposition", "attachment; filename=submittedData.xls");
                    System.Xml.Xsl.XslCompiledTransform xtExcel = new System.Xml.Xsl.XslCompiledTransform();
                    xtExcel.Load(HttpContext.Current.Server.MapPath("Excel.xsl"));
                    xtExcel.Transform(xml, null, response.OutputStream);

                    break;

                case "CSV":
                    response.ContentType = "application/octet-stream";
                    response.AddHeader("Content-Disposition", "attachment; filename=submittedData.csv");
                    System.Xml.Xsl.XslCompiledTransform xtCsv = new System.Xml.Xsl.XslCompiledTransform();
                    xtCsv.Load(HttpContext.Current.Server.MapPath("Csv.xsl"));
                    xtCsv.Transform(xml, null, response.OutputStream);

                    break;
            }
            
            response.End();
        }
and javascript code...

ToExcel: function () {
        GalaxyReport.FORMS._1.saveData();
        App.direct.DownloadFile('Excel',{
            isUpload: true,
            buffer: 300,
            success: function (result) {
                Ext.Msg.alert('Message', result);
                setTimeout(function () {
                }, 2000);
            },
            failure: function (error, response) {
                Ext.Msg.show({ title: 'Message', icon: Ext.MessageBox.ERROR, msg: error, buttons: Ext.Msg.OK });
            }
        });
        setTimeout(function () {
        }, 2000);
    },

    ToCSV: function () {
        GalaxyReport.FORMS._1.saveData();
        App.direct.DownloadFile('CSV',{
            isUpload: true,
            buffer: 300,
            success: function (result) {
                Ext.Msg.alert('Message', result);
                setTimeout(function () {
                }, 2000);
            },
            failure: function (error, response) {
                Ext.Msg.show({ title: 'Message', icon: Ext.MessageBox.ERROR, msg: error, buttons: Ext.Msg.OK });
            }
        });
        setTimeout(function () {
        }, 2000);
    },

    saveData: function () {
        var grid = Ext.getCmp("gplVoucher");
        var d = Ext.getCmp("GridData");
        d.setValue(Ext.encode(grid.getRowsValues({ selectedOnly: false })));
    }
