  This should be it, assuming that all Entry elements now get this keyboard (as I think MonoTouch.Dialog does by default):

  [assembly: ExportRenderer(typeof(Entry), typeof(DoneEntryRenderer))]
  namespace MyProject.iOS.Renderers
  {
      public class DoneEntryRenderer : EntryRenderer
      {
          protected override void OnModelSet(VisualElement model)
          {
              base.OnModelSet(model);
              var textField = (UITextField)this.Control;
              textField.ReturnKeyType = UIReturnKeyType.Done;
          }
      }
  }

  I think that's not exactly what he was looking for. Instead, try setting the InputAccessoryView property of the UITextField to a UIView that contains the widgets you need.

  Thanks much René, that's what I was looking for. With your hint and the following article I was able to implement what I needed ;-)

  Pedro, Can you share the code you used to add the InputAccessoryView to an Xamarin.Forms.Edit control? I have like 50 fields on my various pages and I want to automatically add the InputAccessoryView to each of them, including a picker view if possible.

  Thanks

  I can't share the exact code I'm using as that code is actually my client's code, but here is the idea:

  Have a new Entry that extends Xamarin.Forms' Entry, like class MyEntry : Entry and create a custom renderer for it that extends EntryRenderer, like class MyEntryRenderer : EntryRenderer and on the OnElementChanged method you can set this.Control.InputAccessoryView to any UIView. You can follow this link to create an appropriate UIToolbar to set it here.

  Then in your app just reference MyEntry instead of Entry and if the renderer is implemented correctly you'll see that the InputAccessoryView appears.

  [assembly: ExportRenderer(typeof(MyEntry), typeof(MyEntryRenderer))]
  namespace MyProject.iOS.Renderers
  {
      public class MyEntryRenderer : EntryRenderer
      {
          protected override void OnElementChanged(ElementChangedEventArgs<Entry> args) {
          {
              base.OnElementChanged(args);
              this.Control.InputAccessoryView = (...) ; // do your magic here
          }
      }
  }

  Thanks with this and about 4 other posts I was able to get a custom view with the close button (and a bunch of other fun buttons that I'm going to remove) working with Xamarin.Forms

  With the information on this post, I was able to get this working in iOS, but I need to be able to replicate this functionality on Android. Can this be done in a similar fashion for Android by modifying the Renderer?

  Thanks,
  Doug

  It was necessary to write my own renderer for Entry, so here is full code (all YOU need to do is just change your namespace )...

  using Xamarin.Forms;
  using Xamarin.Forms.Platform.iOS;
  using MonoTouch.UIKit;
  using System.Drawing;
  
  
  [assembly: ExportRenderer(typeof(Entry), typeof(Example.Renderers.CustomEntryRenderer))]
  
  namespace Example.Renderers
  {
      public class CustomEntryRenderer : EntryRenderer
      {
          protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
          {
              base.OnElementChanged(e);
  
              // Check for only Numeric keyboard
              if (this.Element.Keyboard == Keyboard.Numeric) {
                  this.AddDoneButton ();
              }
          }
  
          /// <summary>
          /// Add toolbar with Done button
          /// </summary>
          protected void AddDoneButton()
          {
              UIToolbar toolbar = new UIToolbar (new RectangleF (0.0f, 0.0f, 50.0f, 44.0f));
  
              var doneButton = new UIBarButtonItem (UIBarButtonSystemItem.Done, delegate {
                  this.Control.ResignFirstResponder ();
              });
  
              toolbar.Items = new UIBarButtonItem[] {
                  new UIBarButtonItem (UIBarButtonSystemItem.FlexibleSpace),
                  doneButton
              };
              this.Control.InputAccessoryView = toolbar;
          }
      }
  }

  public EntryDoneRenderer ()
  {
  }

  protected override void OnElementChanged(ElementChangedEventArgs<Entry> e)
  {
      base.OnElementChanged (e);
  
      if (this.Element.Keyboard == Keyboard.Numeric) 
      {
          // only want the Done on the numeric keyboard type
          UIToolbar toolbar = new UIToolbar (new RectangleF (0.0f, 0.0f, (float)Control.Frame.Size.Width, 44.0f));
  
          var doneButton = new UIBarButtonItem (UIBarButtonSystemItem.Done, delegate {
              this.Control.ResignFirstResponder ();
              Type baseEntry = this.Element.GetType();
              if(baseEntrySendCompleted==null)
                  // use reflection to find our method
                  baseEntrySendCompleted = baseEntry.GetMethod("SendCompleted",BindingFlags.NonPublic|BindingFlags.Instance);
                  baseEntrySendCompleted.Invoke(this.Element,null);            });
  
          toolbar.Items = new UIBarButtonItem[] {  new UIBarButtonItem (UIBarButtonSystemItem.FlexibleSpace),doneButton   };
          this.Control.InputAccessoryView = toolbar;
      }
  }
  

  }

  @VinayKumar.9706 I'm getting null for the SendCompleted event. It used to work but not anymore.

  protected override void OnElementChanged(ElementChangedEventArgs e)
  {
  base.OnElementChanged(e);

      var toolbar = new UIToolbar(new CGRect(0.0f, 0.0f, Control.Frame.Size.Width, 44.0f));
  
      toolbar.Items = new[]
      {
          new UIBarButtonItem(UIBarButtonSystemItem.FlexibleSpace),
          new UIBarButtonItem(UIBarButtonSystemItem.Done, delegate {
              Control.ResignFirstResponder();
              ((IEntryController)Element).SendCompleted();
          })
      };
  
      this.Control.InputAccessoryView = toolbar;
  }

  Has anybody done the equivalent on UWP, to provide a Done button on UWP phones?
