MVVMの仕組みを理解して、簡単に始めたいと思います。Bindingを使ってテキストボックスにプロパティを入力してくださいMVVM
モデル、ビュー、およびビューモデルを作成しました。私は窓の上に眺めを張った。これは多かれ少なかれ動作します。ビューの 私はプロパティの値で塗りつぶしたいテキストボックスを持っています。テキストボックスは空のままです!
これは私が持っているものです: モデル:
namespace Qbox_0001.Model
{
public class RegistratieModel
{
}
public class Registratie : INotifyPropertyChanged
{
//Fields
private string programmaNaam;
//eventhandler die kijkt of een property wijzigt
public event PropertyChangedEventHandler PropertyChanged;
private void RaisePropertyChanged(string property)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(property));
}
}
//Properies
public string ProgrammaNaam
{
get { return programmaNaam; }
set
{
if (programmaNaam != value)
{
programmaNaam = value;
RaisePropertyChanged("ProgrammaNaam");
}
}
}
}
}
