"Illegal characters in path." Visual Studio WinForm Design View
- by jacksonakj
I am putting together a lightweight MVP pattern for a WinForms project. Everything compiles and runs fine. However when I attempt to open the WinForm in design mode in Visual Studio I get a "Illegal characters in path" error. My WinForm is using generics and inheriting from a base Form class. Is there a problem with using generics in a WinForm?
Here is the WinForm and base Form class.
public partial class TapsForm : MvpForm<TapsPresenter, TapsFormModel>, ITapsView
{
public TapsForm()
{
InitializeComponent();
}
public TapsForm(TapsPresenter presenter)
:base(presenter)
{
InitializeComponent();
UpdateModel();
}
public IList<Taps> Taps
{
set { gridTaps.DataSource = value; }
}
private void UpdateModel()
{
Model.RideId = Int32.Parse(cboRide.Text);
Model.Latitude = Double.Parse(txtLatitude.Text);
Model.Longitude = Double.Parse(txtLongitude.Text);
}
}
Base form MvpForm:
public class MvpForm<TPresenter, TModel> : Form, IView
where TPresenter : class, IPresenter
where TModel : class, new()
{
private readonly TPresenter presenter;
private TModel model;
public MvpForm()
{
}
public MvpForm(TPresenter presenter)
{
this.presenter = presenter;
this.presenter.RegisterView(this);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (presenter != null)
presenter.IntializeView();
}
public TModel Model
{
get
{
if (model == null)
throw new InvalidOperationException("The Model property is currently null, however it should have been automatically initialized by the presenter. This most likely indicates that no presenter was bound to the control. Check your presenter bindings.");
return model;
}
set { model = value;}
}
}
