Cannot convert type IEnumerable to ObservableCollection…are you missing a cast?

Question

I\'m trying to return entities where the bool \"isAssy\" is true:

 public ObservableCollection ParentAssemblyBOM
 {
      get {return          


        

Answer 1

ObservableCollection has an overloaded constructor that accepts an IEnumerable as a parameter. Assuming that your Linq statement returns a collection of MasterPartsList items:

public ObservableCollection ParentAssemblyBOM
{
    get 
    {
        var enumerable = this._parentAssemblyBOM
                             .Where(parent => parent.isAssy == true);

        return new ObservableCollection(enumerable); 
    }
}
