I'm try to bind struct list with labels that created dynamically.

code of structure:

public struct PrinterToGridBinds
 
 public string extPrinterName get; set; 
 public string extIcecreamType get; set; 
 public string extBatchNumber get; set; 
 public string extBeginingDate get; set; 
 public string extPrinterState get; set; 
 public string extBatchCounter get; set; 
 public string extDIOCounter get; set; 

 public PrinterToGridBinds(string extPrinterName, string extIcecreamType, string extBatchNumber, string extBeginingDate,
 string extPrinterState, string extBatchCounter, string extDIOCounter)
 
 this.extPrinterName = extPrinterName;
 this.extIcecreamType = extIcecreamType;
 this.extBatchNumber = extBatchNumber;
 this.extBeginingDate = extBeginingDate;
 this.extPrinterState = extPrinterState;
 this.extBatchCounter = extBatchCounter;
 this.extDIOCounter = extDIOCounter;
 
 

 public List<PrinterToGridBinds> lst_PrinterToGridBindings = new List<PrinterToGridBinds>();

Initialize list of structures

private void PrinterToGridBindingInit()
 
 for (int i = 0; i < PrinterNumber; i++)
 
 lst_PrinterToGridBindings.Add(new PrinterToGridBinds("Num " + (i + 1).ToString(), "-", "-", "-", "-", "-", "-"));
 
 

and try to bind this with labels that creating dynamically. Code below:

for (int i = 0; i < 8; i++)
 
 Label lbl_PrinterName = new Label();
 lbl_PrinterName.Name = "Name_" + i.ToString();
 Binding lbl_Binding = new Binding Path = new PropertyPath(lst_PrinterToGridBindings[i].extPrinterName), Mode = BindingMode.OneWay ; 
 lbl_PrinterName.SetBinding(Label.ContentProperty, lbl_Binding);

 Grid.SetRow(lbl_PrinterName, i + 2);
 Grid.SetColumn(lbl_PrinterName, 3);
 grd_WorkArea.Children.Add(lbl_PrinterName);
 

And I don't see any result after program runs. From other side, if I define property

public string PropName1 get; set; = "PropTest";

and add this property to binding like this:

Binding lbl_Binding = new Binding Path = new PropertyPath("PropName1"), Mode = BindingMode.OneWay ;

All works like a charm! Where is my mistake?How to bind structure data with labels dynamically?

Seems like, for your working sample (with PropName) you define the property name in property path, but for printers you define a property value lst_PrinterToGridBindings[i].extPrinterName. Have a look at msdn. You also should specify the Source for binding

In order to show a list of elements, use an ItemsControl. Assign or bind its ItemsSource property to a collection of item objects. Set its ItemTemplate to a DataTemplate with UI elements that bind to properties of the item class.

<ItemsControl x:Name="printerList">
 <ItemsControl.ItemTemplate>
 <DataTemplate>
 <TextBlock Text="Binding extPrinterName"/>
 </DataTemplate>
 </ItemsControl.ItemTemplate>
</ItemsControl>

Code behind:

printerList.ItemsSource = lst_PrinterToGridBindings;
