BUG: Unable to cast object of type with gridGroupingControl.TableControl.Refresh()

[Sergey Merkuriev]

I have following exception of casting type in the grid when I bound collection of following objects to the grid

public class DataItem
{
//public ICollection Attributes { get; private set; }
public IDictionary Reference { get; private set; }
public string Name { get; private set; }
}


Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' to type 'System.Collections.IList'.
