Hi,

I have an Ultragrid bound to a class DataClass implementing an interface IDataClass, derived from another interface IDataBaseClass.

No columns are then generated for the poperties of the base interface IDataBaseClass

public interface IDataBaseClass
{
int Id { get; }
}

public interface IDataClass : IDataBaseClass
{
int IntDataItel { get; }
string StringDataItem { get; }
}

public class DataClass : IDataClass
{
public int Id { get; set; }
public int IntDataItel { get; set; }
public string StringDataItem { get; set; }
}

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

// this only shows the properties of the interface IDataClassand and NOT of the interface IDataBaseClass
// Thus we have two columns named IntDataItel and StringDataItem
List data1 = new List{
new DataClass{ Id=1, IntDataItel = 11, StringDataItem = "S1"},
};
ultraGrid1.DataSource = data1;

}
}

However, in the following case I do also get the columns for the base class:

public class BaseClass
{
public int Id { get; set; }
}

public class DerivedClass : BaseClass
{
public int IntDataItel { get; set; }
public string StringDataItem { get; set; }
}

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

// this shows both the properties of the class DerivedClass AND BaseClass

// Thus we have two columns named Id, IntDataItel and StringDataItem
List data2 = new List{
new DerivedClass{ Id=1, IntDataItel = 11, StringDataItem = "S1"},
};
ultraGrid1.DataSource = data2;
}
}

I would like to also have columns generated in the case of interface inheritance.

Is this possible?

Attached you'll find a sample project.

We are using the 16.1 version of the controls

Thanks
