Как создать отчет для приложения Магазина Windows?
Я занимаюсь разработкой LOB-приложения, ориентированного на Windows Store, и мне хотелось бы знать, какие есть варианты для создания пользовательских отчетов для него. Пользователь может захотеть, кроме печати, экспортировать в PDF или CSV.
Я не знаю, какой API есть для приложений Windows Store. Поиск в Google не сильно помог.
Если бы не было инструмента для создания отчета, что бы вы предложили, ребята?
Смотря PrintSample от Microsoft, он печатает содержимое компонента сетки. Я сомневаюсь, как установить размер страницы в этом случае, чтобы я мог правильно отформатировать отчет.
Любая помощь / идея высоко ценится.
Спасибо!

Я поручил клиенту создать приложение для Магазина Windows для их планшета RT. Я понятия не имел, что технология была настолько... ограниченной в то время. Например, отсутствуют System.Data, StreamWriter и многие другие обычные функциональные возможности бизнес-приложений... Вероятно, самым удивительным для меня был стандартный метод построения отчетов. Похоже, что до сих пор они не были интегрированы в SSRS (надеюсь, скоро?). Что касается Crystal Reports, то в настоящее время у них нет планов расширения до платформы Windows RT.
Меня не впечатлил образец Print от Microsoft, который больше всего походил на взлом. Поэтому я создал более подходящий метод для своих нужд. Я уверен, что многие из вас придумали свои собственные методы, в том числе приобретение сторонних инструментов, но я сгенерировал свои собственные отчеты с помощью HTML и текущих доступных для WindowsRT методов SQLite (насколько я скучаю по System.Data!). Как уже упоминалось, StreamWriter кажется не очень правдоподобным с Windows RT, поэтому я провел небольшое исследование альтернативы, и это то, что работает для меня:
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();
}
}
// GET CUSTOMER VALUES
using (var db = new SQLite.SQLiteConnection(dbPath))
{
var objCustomer = db.Table<Customer>().Where(c => c.CustomerID == currentCustomerID).Single();
strCustomerName = objCustomer.FirstName + " " + objCustomer.LastName;
strCustomerAddress = objCustomer.Address1 + " " + objCustomer.Address2 + " " + objCustomer.City + " " + objCustomer.State + " " + objCustomer.Zip;
strCustomerPhone = objCustomer.Phone1;
strCustomerNotes = objCustomer.CustomerNote;
db.Close();

К сожалению, нет свободной библиотеки (tool/sdk) для генерации отчетов PDF/Excel в Windows Store App сейчас.
Но если у вас есть деньги на покупку - проверьте PDFTron и Syncfusion
