RequireEmptyConstructorException
posted

Hello,

I have a grid with a couple of manually created fields of Type TextColumn. I've set AutoGenerateColums to false.

Now I'm trying to bind ( with ItemSource)  the grid with a collection of my data of Type ObservableCollection<string[]>.

I'm always getting the RequireEmptyConstrucor Exception: The DataManager attempted to create an instance of a class which does not have an empty parameter list.

I really hope someone can help me with this issue. Thanks.

    Hi, 

    I'm facing the same issue and can't able to resolve it.

    I'm assign ObservableCollection<Class1>(records) to xamgrid.itemsource.

    Class1 constructor contains 3 more classes IEnumerable<class2/3/4> in parameter and last argument is string [].

    Class2/3/4 has empty constructor but string[] don't. I need to use string[] or list<string> as last parameter.

    How can I achieve this or resolve this issue.

    Please Help !!!

    Thanks
