我正在开发针对Windows应用商店的LOB应用，我想了解为其创建自定义报告的选项。除打印外，用户可能还希望导出为PDF或CSV。
我不知道Windows商店应用的API。谷歌搜索并没有多大帮助。
如果没有任何工具可以创建报告，你们会建议什么？
从Microsoft查看PrintSample，它会打印网格组件的内容。我怀疑在这种情况下如何设置页面大小，以便我可以正确格式化报告。
非常感谢任何帮助/想法。
谢谢！

不幸的是，现在没有用于在Windows Store App生成PDF / Excel报告的免费库（工具/ sdk）。
但如果您有钱购买 - 请查看PDFTron和Syncfusion

我已经致力于让客户为他们的RT平板电脑构建一个Windows应用商店应用。我不知道当时的技术是如此......有限。例如，没有System.Data，StreamWriter和许多其他常见的业务应用程序功能缺失......对我来说，最令人惊讶的可能是构建报告的标准方法。到目前为止，他们似乎没有SSRS集成（希望很快就会到来？）。查看Crystal Reports，他们目前没有计划扩展到Windows RT平台。
我也不会对微软的打印样本印象深刻，这似乎比任何事情都更糟糕。所以我为我的需求创建了一个更合适的方法。我相信很多人都提出了自己的方法，包括购买第三方工具，但对于我来说，我通过HTML和当前WindowsRT可用的SQLite方法生成我的自定义报告（我多么想念System.Data！）。正如前面提到的，StreamWriter在Windows RT中看起来并不合理，所以我做了一些替代方案的研究，这对我有用：
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();
