Question

It seems like a straight forward task, i want to pass in a public property value from a MVVM View, but i keep getting the “a ‘binding’ cannot be set on the property of type . a ‘binding’ can only be set on a dependencyproperty of a dependencyobject” error.

I am iterate over an observable collection and rendering the item, and i would like to move some Template code into a User control. How the heck can i solve this????

<local:xIPAddressControl UserControlIPAddressText="{Binding Path=IPAddress, RelativeSource={RelativeSource Mode=Self}, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />

UserControl

public partial class xIPAddressControl : UserControl
{
    public xIPAddressControl()
    {
        this.InitializeComponent();
    }


    public string UserControlIPAddressText
    {
        get { return this.xIPAddressTextBlock.Text; }
        set { this.xIPAddressTextBlock.Text = value; }
    }
}

Crazy thing, I was trying to set the User control incorrectly. It needs to be the following.

//this.DataContext = this;

LayoutRoot.DataContext = this;
