Binding to object in code behind

[Luco]

In Window1.xaml.cs I have an object how can I bind to it's properties?

private RamManager ramManager;

public Window1()
{
ramManager = new RamManager();
ramManager.StartThread();

InitializeComponent();
}



what I need is in Window1.xaml

<ProgressBar Name="ramBar" Maximum="{Binding Path=ramManager.TotalRam}" Value="{Binding Path=ramManager.AvailableRam}" />



Thank you in advance :)

First of all, since the RamManager is multithreaded, you'll need to make it's public properties threadsafe.

Next, you need to implement the INotifyPropertyChanged interface in the RamManager.

You also will need to change the bindings in xaml

<ProgressBar Name="ramBar" Maximum="{Binding Path=TotalRam}" Value="{Binding Path=AvailableRam}" />

Finally, you'll need to set the view's data context to the RamManager instance. Something like..
public Window1( )
{
InitializeComponent();

ramManager = new RamManager();

DataContext = ramManager;

ramManager.StartThread( );
}

For a better approach using the MVVM pattern, I'd suggest reading Josh Smith's excellent article.
