Description jmgomez 2015-11-19 06:54:27 UTC
With the latest update of Xamarin.Forms (2.0.0) the SearchBar Element doesn't show the text, the text is there but it doesn't get renderer (it isn't white). 

I had to rewrite the render as a workaround and it works well, so it's something related with the SearchBarRenderer (just in case, the code below only fits my needs):

public class CustomSearchBarRenderer : ViewRenderer<SearchBar, UISearchBar> {
		protected override void OnElementChanged (ElementChangedEventArgs<SearchBar> e){
			base.OnElementChanged (e);
			if (e.OldElement != null || this.Element == null)
				return;
			var nativeSearchBar = new UISearchBar ();
			SetNativeControl (nativeSearchBar);
			Control.Text = Element.Text;
			Control.Placeholder = Element.Placeholder;
			Control.SearchButtonClicked += (sender, e2) => Element.SearchCommand?.Execute(Control.Text);
			Control.CancelButtonClicked += (sender, e2) => Element.Text = "";
			Control.TextChanged += (sender, e2) => Element.Text = Control.Text;
		}

		protected override void OnElementPropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e) {
			base.OnElementPropertyChanged (sender, e);
			if (e.PropertyName == "Text") 
				Control.Text = Element.Text;
			if (e.PropertyName == "Placeholder")
				Control.Placeholder = Element.Placeholder;
		}

The default placeholder color of the SearchBar is also being affected, so the title has been updated to reflect this.
