    Export to excel and csv

    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 })));
        }
    btnToExcel.Listeners.Click.Handler = SCOPE + ".ToExcel();";
    btnToCSV.Listeners.Click.Handler = SCOPE + ".ToCSV();";
    When i run in visual studio it work fine, but when i publish to the host, it download with blank data for excel file and something code for csv file.

    Hello @phongdd10!

    I'm sorry we took so long to reply the inquiry you sent but, as you shown, the issue is when you publish the solution to an IIS server, so it's hard for us to tell what's wrong on that.

    The most likely reason you don't get it to work on the production environment is a misconfiguration on the GalaxyReport tool, which is a third-party we are not able to talk about here.

    You should try to build a very simple application using this library (a static "hello world" report, maybe), and then ensure it works both in the development project and when sent to production, so you troubleshoot the issue from its root, and then climb up in complexity until you isolate the cause of the issue.

    It really, really looks like not an issue with Ext.NET at all -- as far as I can see by a brief lookup on your very extensive code.

    To get faster help here, we'd strongly advice you on reviewing our guidelines, which has some tips on simplifying your test case scenarios. The simplifying process itself helps you find (by yourself) the reasons of issues in most cases:

    Hello @Phongdd10,

    Again, without being able to run the code with a runnable test case, we can't be of much help. But here's my best shot:

    Review your example to perform either like this ajax example: GridPanel > Miscellaneous > Data Export Ajax
    Or this postback example: GridPanel > Miscellaneous > Data Export PostBack

    At least here you can base your example off something that we know that works. If you want these examples in v2 (they should not have much difference anyway):
    - Ext.NET 2: GridPanel > Miscellaneous > Data Export Ajax
    - Ext.NET 2: GridPanel > Miscellaneous > Data Export PostBack

    Remember we're in v4 forums, and the answers here are based on Ext.NET 4. Have you temporarily downgraded to 2.5.3 to test and got same result, or are you all time on Ext.NET 2.5.3? If so, we can move this thread to 2.x help for clarity.

    Hope this helps!
