Sorting error when datasource is a sub-object collection

[Phi]

Hello again,

My datasource is a collection of objects, with sub-objects. The databinding is OK, but when I click the row header to perform sorting, an exception is raised.

The following code is the same as the one in the Telerik examples under RadGridView->DataBinding (select sub-object datasource)

ArrayList list = new ArrayList();

list.Add(new MyObj("1"));
list.Add(new MyObj("2"));
list.Add(new MyObj("3"));
list.Add(new MyObj("4"));
list.Add(new MyObj("1"));

radGridView1.GridElement.BeginUpdate();

radGridView1.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("Inner1.TestProp"));
radGridView1.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("Inner1.Inner2.TestProp"));
radGridView1.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("Inner1.Inner2.Inner1.TestProp"));
radGridView1.MasterGridViewTemplate.Columns.Add(new GridViewTextBoxColumn("TestProp"));

radGridView1.GridElement.EndUpdate(false);

radGridView1.DataSource = list;

and the MyObj object is defined as:

public class MyObj
{
    public string _innerText = "";

    public MyObj() {}

    public MyObj(string text)
    {
        _innerText = text;
    }

    public MyObj Inner1
    {
        get
        {
            return new MyObj(this._innerText + "Inner1");
        }
    }

    public MyObj Inner2
    {
        get
        {
            return new MyObj(this._innerText + "Inner2");
        }
    }

    public string TestProp
    {
        get
        {
            return this._innerText;
        }
    }
}

I notice the following:

When I try to sort any column bound to a sub-object (ie. any of the first 3 columns), I get one of the following errors:
"Cannot find the column Inner1.TestProp"
"Cannot find the column Inner1.Inner2.TestProp"
"Cannot find the column Inner1.Inner2.Inner1.TestProp"

The final column sorts OK.

I also noticed that when I run this demo from within Telerik examples, I don't get an exception, but the sorting doesn't work properly for the first 3 columns.

Cheers
