    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.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.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  
                return new MyObj(this._innerText + "Inner1");  
        public MyObj Inner2  
                return new MyObj(this._innerText + "Inner2");  
        public string TestProp  
                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.
