问题
I'm developing a LOB app targeted to windows store and I'd like to know what are the options to create custom reports for it. The user may want to, besides printing, export to PDF or CSV.
I don't know which API there is for windows store apps. Googling didn't help much.
If there isn't any tool to create the report, what would you guys suggest?
Looking the PrintSample from Microsoft, it prints the content of a grid component. I doubt how to set the size of page in this case so I can format the report properly.
Any help/idea is much appreciated.
Thanks!

I've committed to a client to build them a Windows Store App for their RT Tablet. I had no idea the technology was so... limited at the time. For example no System.Data, StreamWriter, and many other common business application functionalities are missing... Probably most surprising of all for me was a standard method of building reports. So far their appears to be no SSRS integration (Hopefully coming soon?). Looking at Crystal Reports they currently have no plans of extending to the Windows RT Platform.
I wasn't to impressed with Microsoft's Print sample either, which seemed like a hack more than anything. So I created a more suitable method for my needs. I am sure many of you have come up with your own methods including purchasing third party tools, but as for me I generated my custom reports through HTML and the current WindowsRT available SQLite methods (How Much I miss System.Data!). As mentioned StreamWriter doesn't seem really plausible with Windows RT so I did a little research for an alternative and this is what works for me:
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;

Unfortunately there is no free library (tool/sdk) for generating PDF/Excel reports in Windows Store App now.
But if you have money for buying - check PDFTron and Syncfusion
