Hello,
I've this usercontrol here: https://www.vbforums.com/showthread....ent&highlight=
that have the property SelectedEndianess

and in my app the the property:

Private Const m_Defaultendianess = 0
    Private _myendianess As String = m_Defaultendianess
    <DefaultValue(m_DefaultZoomV)>
    Public Property myEndianess() As String
        Get
            Return _myendianess
        End Get
        Set(ByVal value As String)
            SetAndNotify(_myendianess, value) 
        End Set
    End Property

I'm trying to bind them so:

 <local:myBitButton  x:Name="mybtnBitButton" Grid.Row="1" EndianessChanged="{s:Action mybtnBitButton_EndianessChanged}" SelectedEndianess="{Binding myEndianess , UpdateSourceTrigger=PropertyChanged}" ></local:myBitButton>

but I'm getting this error: XDG0062 Object of type 'System.Windows.Data.Binding' cannot be converted to type 'System.String'.
Any advice?
