You can auto fit the SfTreeView node height based on its content using QueryNodeSize in Xamarin.Forms.


Setting node height based on its content using GetActualNodeHeight method.

namespace TreeViewXamarin
    public class Behavior : Behavior<SfTreeView>
        protected override void OnAttachedTo(SfTreeView bindable)
            bindable.QueryNodeSize += Bindable_QueryNodeSize;
        private void Bindable_QueryNodeSize(object sender, QueryNodeSizeEventArgs e)
            // Returns item height based on the content loaded.
            e.Height = e.GetActualNodeHeight();
            e.Handled = true;
        protected override void OnDetachingFrom(SfTreeView bindable)
            bindable.QueryNodeSize -= Bindable_QueryNodeSize;
