How to bind PropertyGrid to GridView selectedItem in code?

[Markus]

I have a GridView and a PropertyGrid both created in code not XAML.
Now I try to bind the selected item of the GridView to the PropertyGrid also via code and not XAML.
I tried something like this:

Binding propGridBinding = new Binding("SelectedItem");
propGridBinding.ElementName = "myTreeListView";   // assuming this is the name of the GridView
propertyGrid.Item = propGridBinding;

But when I try to run this code I get an error message like this:
An unhandled exception of type 'System.NotSupportedException' occurred in System.dll
Additional information: 'CultureInfoIetfLanguageTagConverter' is unable to convert '(null)' to 'System.String'.

I even get the same type of error if I just try to bind the PropertyGrid to a visual element to be able to view and edit its properties.

I must be missing something.

Any help is very much appreciated.

Thanks,
Markus

Hi Markus,

You can set PropertyGrid's Item to be the SelectedItem of RadGridView in its SelectionChanged event. Please check the following code snippet for a reference:

          RadPropertyGrid myPropertyGrid;
        RadGridView myGridView;
        public MainWindow()
        {
            InitializeComponent();

            myGridView = new RadGridView();
            myGridView.ItemsSource = Club.GetClubs();

            myGridView.IsSynchronizedWithCurrentItem = true;
            myGridView.SelectionChanged += myGridView_SelectionChanged;

            myPropertyGrid = new RadPropertyGrid();
            myPropertyGrid.Item = myGridView.SelectedItem;
        }

        void myGridView_SelectionChanged(object sender, SelectionChangeEventArgs e)
        {
            myPropertyGrid.Item = myGridView.SelectedItem;
        }

I hope this helps.

Hi Markus,

Just a quick follow-up - you can bind PropertyGrid's Item to GridView's SelectedItem in code-behind like so:

Binding binding = new Binding("SelectedItem") { ElementName = "myGridView" };
this.myPropertyGrid.SetBinding(RadPropertyGrid.ItemProperty, binding);

Hi Yoan,

I just have the same issue , I am generating rad grid view dynamically and want to set GridView's SelectedItem as my SelectedCustomer Property so I just tried 

 Binding binding = new Binding("SelectedItem") { ElementName = "radGridView" };
            radGridView.SetBinding(RadPropertyGrid.ItemProperty, binding);

from modelview( I m nothing doing in .xaml file every thing I have to code from viewmodel)

And tried to get value inside 

 public DynamicEntity SelectedCustomer
        {
            get { return _selectedCustomer; }
            set { _selectedCustomer = value; OnPropertyChanged("SelectedCustomer"); } //HERE I JUST SET BREAK POINT ON SELECTION OF GRID VIEW ROW BUT NOTHING IS  CHANGE.
        }

Then I just tried radGridView.SelectionChanged += new EventHandler<SelectionChangeEventArgs>(myGridView_SelectionChanged); it works fine but as in mvvm pattern , it's better to not bind any events with mvvm so can you tell how to resolve it , we are still trying telerik control and we are on poc base.....

Hi,

I am sending you a sample project which demonstrates how to achieve the desired behavior. Basically, I am binding GridView's SelectedItem property to a SelectedItem property of my ViewModel, then the PropertyGrid's Item property is bound to ViewModel's SelectedItem property and everything works as expected.

I hope this helps.
