I am back again with a post on Xamarin.Forms Custom Renderer. My earlier post was on the creation of a Custom Renderer for Entry.

Well, this time, we are going to solve something different which might not have been faced by many users. Sometimes, it happens that you want to display some lines of Text to the user like Read Me or just some Random text. For instance, consider the following code snippet:

<Label Text="{Binding SomeText}" HorizontalOptions="Fill">

Here, when the App is run, the text will be filled in the Label. However, if the number of lines crosses 100, the text will get clipped. In case, you want some more lines, you can always create a Custom Renderer for Label.

You can try to create something like this:

In Android

public class CustomLabelRenderer: LabelRenderer
{
    protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
    {
        base.OnElementChanged(e);
        Control.SetMaxLines(500);
    }
}

In iOS

public class CustomLabelRenderer : LabelRenderer
{
    protected override void OnElementChanged(ElementChangedEventArgs<Label> e)
    {
        base.OnElementChanged(e);

        if (Control != null)
        {
            UILabel label = Control;
            label.Lines = 500;
        }
    }
}

Hope this helps someone.

Happy Coding!
