는 어떻게이 XAML 페이지가

Question

을 인쇄의 DataContext를 데이터 바인딩하기 :

A) PagePrinting.xaml
B) FormattedPage.xaml

 
--1--- in FormattedPage.xaml , I have a RichtextBlock : 

<RichTextBlock> 
<Paragraph> 
<InlineUIContainer> 
    <ItemsControl ItemsSource="{Binding YourItems}"> 
    <ItemsControl.ItemTemplate> 
     <DataTemplate> 
      <!-- Data Template --> 
     </DataTemplate> 
    </ItemsControl.ItemTemplate> 
</ItemsControl> 
</InlineUIContainer> 
</Paragraph> 
</RichTextBlock> 


------2-- In PagePrinting.xaml : 

I have the data from SQLite Db for FormattedPage.XAML for above (1) 


ObservableCollection <Transaction> TransCollection = new ObservableCollection <Transaction>(); 

OnPageLoad : 

TransCollection.Clear(); 

var db = new SQLiteAsyncConnection(dbPath); 
var Trans = await db.QueryAsync <BizTransaction>("Select * From BizTransaction Where SalesId = '" + Id + "'");   

int intRecord = Trans.Count(); 

if (intRecord != 0) 
{ 
    foreach (var _trans in Trans) 
    { 
     int Id = _trans.Id; 
     string Name = _trans.Description; 
     string ItemNo = _trans.No; 
     int Qty = (int)_trans.Quantity; 
     decimal Price = _trans.UnitPrice; 
     decimal LineAmt = _trans.LineAmount; 

     //-- create a collection 
    AddToList(Id, Name, ItemNo, Qty, Price, LineAmt); 

    } 


this.DataContext = TransCollection; 

FrameworkElement page1; 

page1 = new FormattedPage(); 

page1.DataContext = this.DataContext; 

CanvasPrintContainer.Children.Add(page1); 



The problems: 

1) is this correct ? 

this.DataContext = TransCollection; 
page1.DataContext = this.DataContext; 

2) How to do Binding in FormattedPage.xaml using this DataContext? 

3) What need to be done in xaml section for PagePrinting for DataBinding ? 


Thanks
