I have a nested user control ( user control in other user control ) . Suppose that User Control 2 is in User Control 1 ,

I'm trying to set the Dependency property of TextDependesce in the User Control 1 ,

what I have exactly: The User Control 2 contains Dependency property as shown


I'm trying to send the parameter from user control 1 into user control 2 in xaml code .
What I mean exactly set the Dependency property of TextDependesce in the other User Control 1.
how can I do that?

Note : the problem is that the TextDependecse will always take null because that the User Control 2 will initialize before the User Control 1 and this was tested using Debugging with break points , I'm searching for a solution to take the value in the user Control 1.



I will give an example :


Suppose that the User Control 1 is button and the user Control 2 is a Window , I need to set the text of button from user Control 2 , what I have as approach is send a parameter of the button text from user Control 1 to user Control 2 in order to modify it inside the UC1 that is supposed a Window .

What I have tried:

public partial class UC_Control2 : UserControl, INotifyPropertyChanged
    {
        public string TextDependecse
    {
        get { return (string)GetValue(TextDependecseProperty); }
        set { SetValue(TextDependecseProperty, value); }
    }

    public static readonly DependencyProperty TextDependecseProperty =
        DependencyProperty.Register(@"TextDependecse", typeof(string), typeof(UC_Control2), new PropertyMetadata(String.Empty));

<pre>
 <local1:UC_Control1 toog="False" TextDependecse="test1"  
            DockPanel.Dock="Top" Height="30" Width="160" FlowDirection="LeftToRight"
            Grid.Row="0" Grid.Column="2" 
            />
