question from link:

I keep getting this exception while using Andrew Davey's BindingListView (http://blw.sourceforge.net/). I am using ServiceStack OrmLite . My objects looks like this:

public class Category
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class Product
{
    public int Id { get; set; }
    public int CategoryId { get; set; }
    public int ProductTypeId { get; set; }
    public string Name { get; set; }

    [Reference] 
    public Category Category { get; set; }
}

I have no idea how to pass this exception.

i think this is happening because

product.Name
product.Category.Name

product.Id
product.Category.Id

when that lib does reflection to get Property, it gets 2 "Name".

code doesnt know, Which one do you want. Product.Name from or Product.Category.Name.

my proposed solution is blw shoud ignore properties if it is customClass (Category which is inside of Product)

public class Product
{
    public int Id { get; set; }
    public int CategoryId { get; set; }
    public int ProductTypeId { get; set; }
    public string Name { get; set; }

     /*       blw should not read the properties of this customClasses      */
    public Category Category { get; set; }
}

I'm attempting to use BindingListView with DataGridViewAutoFilter, but it seems that it uses string expression filters, therefore whenever I try AutoFilter, it throws an exception which appears to come from your code:

        string IBindingListView.Filter
        {
            get
            {
                return Filter.ToString();
            }
            set
            {
                throw new NotSupportedException("Cannot set filter from string expression.");
                //TODO: Re-instate this line once we have an expression filter
                //Filter = new ExpressionItemFilter<T>(value);
            }
}

It looks like the dynamic code generation for comparison generates an invalid IL code. I tried this for the Foo example for sorting on the Abscissa. The function private static Comparison<T> BuildValueTypeComparison( PropertyInfo pi, ListSortDirection direction ) returns in invalid IL code.

Hello,

I have a column which binds to images stored as byte[]. When one row contains NULL in this property, an exception is thrown from AggregateBindingListView.cs, method CreateProvidedView().
The cause is that Activator.CreateInstance(viewType, list) doesn't know which constructor to take, given that list is null.

Please provide a fix for this case.

Thanks,
Cantemir
