Quick question about you tutorial

Hello,

Thank you so much for your tutorial about xamarin.forms gridview.

I'm betting an error and I like to check if you know what I'm doing wrong.

I'm getting Unhandled Exception:

System.MissingMethodException: Constructor on type 'TaskTileTemplate' not found. occurred

Thank you !!!

TKCustomMap Xamarin forms pin not showing , bindings not working

I may be wrong and I'm sorry if I bother you. have you worked with the TKCustomMap project?

I have been trying different solutions and can't get that pin to show on the map. any suggestions? Thank you

var lastKnownPosition = new TMAP.Position(66.076910, -180.253509);

        Pins.Add(new TKCustomMapPin
        {

            Position = new TMAP.Position(246.076910, -480.253509),
          
            Title = "test",
            ShowCallout = true,
            Image = "Iam.png",
            DefaultPinColor = Color.Blue,
            IsCalloutClickable = true,
           
        });

        MapRegion = TMAP.MapSpan.FromCenterAndRadius(lastKnownPosition, TMAP.Distance.FromMiles(5)).WithZoom(10);

This binding
#region Observable Pins
private ObservableCollection _Pin;
public ObservableCollection Pins
{
get { return this._Pin; }
set
{
if (this._Pin != value)
{
this._Pin = value;
// this.OnPropertyChanged();
OnPropertyChanged(this, new PropertyChangedEventArgs("AllowPins"));
}

        }
    }
    #endregion

Xamarin.Forms GridView

Hi good morning, I see your code and I have a question. From where "ctrl".

 <ctrl:GridView
      HorizontalOptions="FillAndExpand"
      VerticalOptions="FillAndExpand"
      x:Name="GrdView"
      RowSpacing="5"
      ColumnSpacing="5"
      MaxColumns="2"
      TileHeight="120"
      CommandParameter="{Binding}"
      Command="{Binding StartTaskCommand}" 
      IsClippedToBounds="False">
  </ctrl:GridView>

Thank you

FluentValidation for Xamarin Forms revisited...

Hi Chase,

I started with your code and made several changes to support the latest version of FluentValidation (10.0). I also perceived a weakness in that, if data is never entered, SetPropeerty is never called so validation will never occur. I solved that by implementing an Unfocused event handler to force validation when the user navigated away from the field. I call my version EntryEx (it's shorter). I plan to send my version to the Xamarin Community Toolkit, however, I wanted to ask permission first, since I started with code you developed. I attached my code so that you can update yours if you so wish. BTW, I also moved to C#9.0 so there may be a few backward compatibility issues to consider.

regard this answer you did years ago?

Xamarin.Forms GridView ItemClick/Tap

Referred your blog post for enabling Xamarin.Forms Gridview, but didn't find a way to pass command to event handler for ItemClick or Tap event.

Question on ControlTemplates...

I reviewed your article, "How and When to use Control Templates in Xamarin Forms", and also your article, "Realtime Validation in Xamarin Forms with FluentValidation". Both of them have helped me tremendously build a tailored implementation of the latter (a few changes were required because of some breaking changes to FluentValidation, plus I have a similar but different ViewModelBase class hierarchy.)

I have run into one issue I've been so far unable to resolve: I have a number of EntryEx controls (my version of your ExtendedEntry control) on a view (page); several are required. There is nothing in the logic to detect someone NOT filling out a field. Validation ONLY occurs when SetProperty is called. If a user NEVER touches a field, it is never validated. I had hoped to use the Unfocused event of Entry to force validation but keep getting InvalidOperationExceptions because the Entry is in a ControlTemplate. I tried using an EventToCommandBehavior inside the custom control but ran into the same problem.

Any thoughts come to mind?

Thanks in advance for anything you might be able to provide,

Gary
