Learning MVVM\WPF\C# by building a simple master\details app. I have a MainView which holds the MasterView, DetailView, and ControlsView. I have added buttons (ICommand) to all views. They all work properly except the one on the DetailView. The problem is the view's datacontext (DataContext="{Binding SelectedMediaItem}"). On the DetailView, if I add a main grid to hold the SelectedMediaItem grid and then add a button the main grid it works fine. Any ideas how I can add a button next to a textbox in the SelectedMediaItem grid? Thank You

  • Try to use paragraphs and add a little more code. And a better description, I got lost. – H H Jul 26 '11 at 16:40
  • Quite difficult to understand your issue, is it with databiding or command, can you post xaml and code-behind? – anivas Jul 26 '11 at 16:56
  • The problem is that setting the DetailView's datacontext to the collection's CurrentItem removes the ability to add buttons to that view. The buttons use commands, such as Command="{Binding SaveCommand}" and they work great except when under the the view's current item datacontext. – Lone Starr Jul 26 '11 at 17:20
  • And who publishes those commands? etc etc. Add a code outline. – H H Jul 26 '11 at 19:32
  • **Hopefully, this will make the problem more understandable. The MasterView's datacontext is "AA", the DetailView's datacontext is "CurrentItem of AA". I need to add a button to the DetailView with it's datacontext binding to just "AA" NOT "CurrentItem of AA" – Lone Starr Jul 26 '11 at 19:43

During my learning of MVVM\WPF\C# I sometime find it difficult to find the proper words to ask my questions. Nevertheless, I have managed to find an answer to my question. 

<Grid DataContext="{Binding AA}">
     <Grid DataContext="{Binding CurrentItem}">       
       <TextBox Text="{Binding Name}" />
     </Grid> 
     <Button Command="{Binding SomeCommand}" />
</Grid>

This code puts the TextBox under the DataContext of "CurrentItem of AA" and the button under the DataContext of "AA". I then use rows,columns and margins to position the button next to the TextBox.

  • You can also replace the Grid tags with StackPanel or DockPanel to get an easier layout (without margins) – H H Jul 30 '11 at 09:54
