如何為Windows Store App創建報告？

Question

我正在開發針對Windows應用商店的LOB應用，我想知道為它創建自定義報告的選項。 除了打印外，用戶可能還希望導出為PDF或CSV。

我不知道Windows應用商店使用哪個API。 谷歌搜索沒有太大幫助。

如果沒有任何工具可以創建報告，那么您會提出什么建議？

查看Microsoft的PrintSample ，它將打印網格組件的內容。 我懷疑在這種情況下如何設置頁面大小，因此我可以正確設置報告的格式。

任何幫助/想法非常感謝。

謝謝！

Answer 1

不幸的是，現在Windows Store App沒有免費的庫（工具/ sdk）來生成PDF / Excel報告。
但是，如果您有錢購買-檢查PDFTron和Syncfusion

Answer 2

我已承諾要為客戶為其RT Tablet構建Windows Store應用程序。 我不知道該技術是如此……當時受到限制。 例如，沒有System.Data，StreamWriter和許多其他常見的業務應用程序功能缺失……對我而言，最令人驚訝的也許是構建報告的標准方法。 到目前為止，他們似乎還沒有SSRS集成（希望很快來嗎？）。 查看Crystal Reports，他們目前沒有擴展到Windows RT平台的計划。

微軟的Print示例也沒有給我留下深刻的印象，它似乎比其他任何東西都更適合黑客攻擊。 因此，我創建了一種更適合我需要的方法。 我敢肯定，你們中的許多人都想出了自己的方法，包括購買第三方工具，但是就我而言，我通過HTML和當前WindowsRT可用的SQLite方法生成了自定義報告（我對System.Data的懷念！！）。 如前所述，StreamWriter在Windows RT中似乎並不切實可行，因此我對替代方案進行了一些研究，這對我來說很有效：

        private async void  PrintEstimate()
    {
        // BUILD ESTIMATE WHICH IS AN HTML PAGE BECAUSE THEIR DID NOT APPEAR TO BE
        // A WAY TO REALLY BUILD REPORTS FOR WINRT APPLICATIONS AT THIS POINT WITHOUT
        // PURCHASING THRIRD PARTY TOOLS.

        // Validate Estimate
        // Are their values in the estimate list?
        if (this.listServices.Items.Count < 1)
        {
            MessageDialog msgDialog = new MessageDialog("You must first add services before you can print an estimate.");
            // Show the message dialog
            await msgDialog.ShowAsync();
            return;
        }

        if (string.IsNullOrEmpty(this.txtTotal1.Text))
        {

            MessageDialog msgDialog = new MessageDialog("You must first add the total before you can print an estimate.");
            // Show the message dialog
            await msgDialog.ShowAsync();
            return;
        }

        var strAppPath = Path.Combine(Windows.ApplicationModel.Package.Current.InstalledLocation.Path, @"EstimateReport\NewAPEMiniLogo.png");
        var dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "APE.db");
        // ESTIMATE VARIABLES
        string dtDateOfEstimate = Convert.ToString(this.dateEstimate.Date.ToString("MM/dd/yyyy"));
        string strCustomerName = null;
        string strCustomerAddress = null;
        string strCustomerPhone = null;
        string strCustomerNotes = null;
        double totalCost = Convert.ToDouble(this.txtTotal1.Text);
        double taxes = .08 * totalCost;
        string strEstimateNote = this.txtNotes.Text;
        string base64;

        // THE WINRT Environment is very limited as far as accessing local resources... and from all that I have found
        // Is purposely limited in allowing this to be done... thus here I am converting the image to a base64 string
        //StorageFolder appFolder = ApplicationData.Current.LocalFolder;
        StorageFolder appFolder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync("EstimateReport");
        StorageFile imageFile = await appFolder.GetFileAsync("NewAPEMiniLogo.png");
        using (var stream = await imageFile.OpenAsync(FileAccessMode.Read))
        {
            var reader = new DataReader(stream.GetInputStreamAt(0));
            var bytes = new byte[stream.Size];
            await reader.LoadAsync((uint)stream.Size);
            reader.ReadBytes(bytes);
            base64 = Convert.ToBase64String(bytes);
        }


        // IF NEW ESTIMATE
        if (currentEstimateID == 0)
        {
            // CREATE/ INSERT NEW ESTIMATE                
            using (var db = new SQLite.SQLiteConnection(dbPath))
            {
                db.CreateTable<APE_Painting_App.DataAccess.Estimate>();
                db.RunInTransaction(() => { db.Insert(new DataAccess.Estimate() { CustomerID = currentCustomerID, EstimateDate = Convert.ToDateTime(dtDateOfEstimate), TotalCost = totalCost, EstimateNotes = strEstimateNote }); });
                string sql = "SELECT last_insert_rowid()";
                currentEstimateID = db.ExecuteScalar<int>(sql);
                db.Close();
            }
        }
        else
        {
            // ELSE UPDATE CURRENT ESTIMATE
            dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "APE.db");
            using (var db = new SQLite.SQLiteConnection(dbPath))
            {
                // THE ONLY THREE ITEMS THAT SHOULD BE CHANGEABLE AT THE ESTIMATE LEVEL ARE TOTAL COST, ESTIMATE NOTES AND ESTIMATE DATE.
                var objEstimate = db.Table<Estimate>().Where(c => c.EstimateID == currentEstimateID).Single();
                objEstimate.EstimateDate = Convert.ToDateTime(dtDateOfEstimate);
                objEstimate.TotalCost = totalCost;
                objEstimate.EstimateNotes = strEstimateNote;
                objEstimate.JobAwarded = this.chkJobAwarded.IsChecked.Value;
                db.Update(objEstimate);
                db.Close();
            }
        }

        using (var db = new SQLite.SQLiteConnection(dbPath))

            strCustomerPhone = objCustomer.Phone1;
            strCustomerNotes = objCustomer.CustomerNote;
