Databinding Property not found, why?

Question

pls help me, why this binding doesn't works, I would like to binding from the PlayerBar.xaml which datacontext is PlayerBarPresenter to PlayerBarPresenter.Card1.ImgCard like this Source = Binding{Source Card1, Path = ImgCard} than I get this exception

A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll System.Windows.Data Error: BindingExpression path error: 'ImgCard' property not found on 'Card1' 'System.String' (HashCode=949723141). BindingExpression: Path='ImgCard' DataItem='Card1' (HashCode=949723141); target element is 'System.Windows.Controls.Image' (Name=''); target property is 'Source' (type 'System.Windows.Media.ImageSource')..

the file is found If is biding in the same property just in the TablePresenter, but I want to binding in the TablePresenter.Card1.ImgCard

UserControl x:Class="poki.View.PlayerBar" Data context is TablePresenter

    <Image Width="50" Height="80" Source="{Binding Source=Card1, Path=ImgCard}" RenderTransformOrigin="0.5,0.5" Canvas.Left="108.358"
Canvas.Top="-8.349">

Answer 1

You set the Source to the string "Card1", of course it does not have any properties that you expect. As the card is in the DataContext you will want to extend the Path (Path=Card1.ImgCard), never set any source when binding to the DataContext or that will be used instead of the DataContext.

Answer 2

Think your binding expression is wrong, please try it like this:

<Image Width="50" Height="80" Source="{Binding Card1.ImgCard}" RenderTransformOrigin="0.5,0.5" Canvas.Left="108.358" Canvas.Top="-8.349">
