Accessing a button click of User Control in Parent page UWP

I have a user control created with name as UserControl.

This user control have a label and a button.

I use this user control in one of my page(lets say Page1), but this user control is generated based on the entries in DB. For eg: I have an entry in DB which has a column with name as 'UC1'. So on page(Page1) load, I dynamically add this usercontrol on the page.

Now when the page is loaded, I want the button click to method to be implemented in Page1 code behind. Could anyone let me know how is this possible. I am facing issue as the use control is dynamically generated and since multiple instances of usercontrols can be generated in the page based on the DB entries.

In short I want to call a method in code behind of parent page for the user control that is dynamically generated inside the parent page

Supposed the Button is named ‘btn1’, and the TextBlock named ‘textBlock1’, you can wire up like this

for (int i = 0; i < 3; i++)

{

    MyUserControl c = new MyUserControl();

    c.btn1.Click += (o, args) =>   

    {

        c.textBlock1.Text = DateTime.Now.ToString(); 

    };



    //then add the user control to the page

    this.stackPanel1.Children.Add(c);

}

And add an x:FieldModifier attribute to the elements so you can access them from outside.

<Button x:Name=“btn1” x:FieldModifier=“public” ...

Thank you I am able to access it now. Now having triggered the button click event from parent page, how can I access the other controls defined in the usercontrol. For eg: I need to change the Text of TextBlock in the user control after the specific button was clicked.

@MadMax see my updated answer, I use an lambada expression to replace the event handler, in the lambda expression, you can access the specific UserControl.

    //then add the user control to the page

    this.stackPanel1.Children.Add(c);

}

And add an x:FieldModifier attribute to the elements so you can access them from outside.
