DataTemplate + MVVM

datatemplate, mvvm, wpf

Solution

So basically, you need to create data templates programmatically... That's not very straightforward, but I think you can achieve that with the `FrameworkElementFactory` class :

public void AddDataTemplateForView(Type viewType)
{
    string viewModelTypeName = viewType.FullName + "Model";
    Type viewModelType = Assembly.GetExecutingAssembly().GetType(viewModelTypeName);

    DataTemplate template = new DataTemplate
    {
        DataType = viewModelType,
        VisualTree = new FrameworkElementFactory(viewType)
    };

    this.Resources.Add(viewModelType, template);
}

I didn't test it, so a few adjustments might be necessary... For instance I'm not sure what the type of the resource key should be, since it is usually set implicitly when you set the DataType in XAML

Problem

I'm using MVVM and each View maps to a ViewModel with a convention. IE MyApp.Views.MainWindowView MyApp.ViewModels.MainWindowViewModel Is there a way to remove the DataTemplate and do it in C#? with some sort of loop? ``` <DataTemplate DataType="{x:Type vm:MainWindowViewModel}"> <vw:MainWindowView /> </DataTemplate> ```
