Hi,

I would create a UserControl called ListUserControl, it should contains RadgridView and other telerik controls. Ok.

But, what is the best way to wrap dependecy properties of GridView?

In primis: ItemSource, I created a dependency property in my user control, but how can I link this property to ItemSource of gridview, what is the best way to do this?

 

public partial class ListViewUserControl : UserControl
    {
        public ListViewUserControl()
        {
            InitializeComponent();
        }
 
        public object ItemSource
        {
            get { return (object) GetValue(ItemSourceProperty); }
            set { SetValue(ItemSourceProperty, value); }
        }
 
        // Using a DependencyProperty as the backing store for ItemSource.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty ItemSourceProperty =
            DependencyProperty.Register(name: "ItemSource", propertyType: typeof(object), ownerType: typeof(object), typeMetadata: new PropertyMetadata(0));
 
 
    }

Hello Dario,

In order to achieve the desired behavior, you will need to make the following modifications to your code:

1) Inside ListViewUserControl.xaml:

<Grid>
    <telerik:RadGridView ItemsSource="{Binding ItemSource, RelativeSource={RelativeSource AncestorType=my:ListViewUserControl}}" />
</Grid>

2) Inside ListViewUserControl.xaml.cs:

public partial class ListViewUserControl : UserControl
{
    public ListViewUserControl()
    {
        InitializeComponent();
    }
 
    public object ItemSource
    {
        get { return (object)GetValue(ItemSourceProperty); }
        set { SetValue(ItemSourceProperty, value); }
    }
     
    public static readonly DependencyProperty ItemSourceProperty =
        DependencyProperty.Register(name: "ItemSource", propertyType: typeof(object), ownerType: typeof(ListViewUserControl), typeMetadata: new PropertyMetadata(null));
}

You may also want to have a look at the following resources:

I hope you find this helpful. Please let me know if you need any further assistance on the matter.
