How to Find Reference to Dynamically Added Xamarin.Forms Element-CodePudding

In Xamarin.Forms we want to add a new button using

    f001content = new Xamarin.Forms.AbsoluteLayout;
    f001content.Children.Add(new Button
        {
            Text = "Button",
            AutomationId = "MyButton",
        }, new Rectangle(0,0,100,40));

How can we find the reference to the button just added so that we can modify it in the future?

CodePudding user response：

Create a reference to it

f001content = new Xamarin.Forms.AbsoluteLayout;

var btn = new Button
    {
        Text = "Button",
        AutomationId = "MyButton",
    }, new Rectangle(0,0,100,40));

 f001content.Children.Add(btn);

If you need to reference it outside the scope it’s created in, you’ll need to declare it at the class level

CodePudding user response：

If you're doing in the code behind, you need to create a variable to hold it.

var coolButton = new Button { Text = "Button", AutomationId = "MyButton" };
f001content.Children.Add(coolButton, new Rectangle(0,0,100,40));

Now when you need to reference it, you can. Note that you'll most likely want coolButton to be class wide or something. If you declare it in a method, you'll lose the reference when you exit the method.
