Retrieve user input from ProWindow dialog without global variables?

succip

Hello,

I'd like to retrieve user input from a ProWindow dialog, then use that input to do a bunch of stuff in my MapView/Tables. Following this example (https://github.com/Esri/arcgis-pro-sdk-community-samples/tree/master/Framework/ProWindowMVVM), I see them using Module1 to store/retrieve global variables, is this best practice in a case where I'll be building multiple ProWindow forms? I worry it will get overwhelming quickly if I want to track 5-10 properties per window.

Is there any other way of retrieving user input from a ProWindow? The ShowDialog() method only returns a boolean. 

Happy to provide more details but I wanted to keep my question as simple as possible. As of right now my code is as follows as an example:

TestButton.cs:

 

 

namespace SurreyTools
{
    internal class TestButton : Button
    {
        private CreateLotWindow _createlotwindow;

        protected override void OnClick()
        {
            if (_createlotwindow != null)
                return;
            _createlotwindow = new CreateLotWindow();
            _createlotwindow.Owner = FrameworkApplication.Current.MainWindow;
            _createlotwindow.Closed += (o, e) => { _createlotwindow = null; };
            _createlotwindow.ShowDialog();
        }
    }
}

 

 

CreateLotsWindowViewModel:

 

 

namespace SurreyTools
{
    public class CreateLotWindowViewModel: PropertyChangedBase
    {
        private string _lotCount;
        public string LotCount
        {
            get => _lotCount;
            set
            {
                SetProperty(ref _lotCount, value, () => LotCount);
            }
        }

        public ICommand SubmitLotNumber => new RelayCommand((createLotWindow) =>
        {
            (createLotWindow as CreateLotWindow).DialogResult = true;
            (createLotWindow as CreateLotWindow).Close();
        }, () => true);
    }
}

 

 

I'd like some way to pass the lotCount property to either my button or any other use case.

On Closed event it destroys objects. I don't use that pattern. You can use local variable like this:

        protected override void OnClick()
        {
            CreateLotWindow createlotwindow = new CreateLotWindow();
            createlotwindow.Owner = FrameworkApplication.Current.MainWindow;
            if(createlotwindow.ShowDialog()== true) {
                var viewModel = createlotWindow.DataContext as CreateLotWindowViewModel;
                var count = viewModel.LotCount;
            }
        }
