Hi Vlad,

Many Thanks for your quick reply..

Unfortunately, this example is not solving my problem...as i mentioned that i have a object with in another object.

I believe VB.NET does not support operator overloading for which we can add 2 class objects to make it as one object.

I would appreciate if you could send me solution to my problem.

I have a "Document Object" which contains following properties

DocumentID
DocumentName
TemplateID
objTemplate is of type Template

I have another object called "Template" which contains the following properties

TemplateID
TemplateName
Field1
Field2

Now i would like to display in the following format which includes Document properties and template properties.

DocumentID
DocumentName
TemplateID
TemplateName
Field1
Field2

Please post me some code..

Many Thanks,
Shashi

Hello,

Check out the code below I implemented taking your scenario into account. Hope this explains what you are looking for.
Template Class:

namespace Document
{
    public class Template
    {

        private string _field1;
        private string _field2;

        public string Field1
        {
            get
            {
                return _field1;
            }
            set
            {
                _field1 = value;
            }

        }

        public string Field2
        {
            get
            {
                return _field2;
            }
            set
            {
                _field2 = value;
            }

        }
    }
}

Document Class:

namespace Document
{

    public class Document
    {
        public Document()
        {
            //
            // TODO: Add constructor logic here
            //
        }

        private Template _template;


        public Template Temp
        {
            get
            {
                return _template;
            }

            set
            {
                _template = value;
            }
        }
    }
}

cs: 

namespace Document
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Document doc = new Document();
            Template temp = new Template();
            temp.Field1 = "field1";
            temp.Field2 = "field2";

            doc.Temp = temp;


            Document doc1 = new Document();
            Template temp1 = new Template();
            temp1.Field1 = "field3";
            temp1.Field2 = "field4";

            doc1.Temp = temp1;


            IList<Document> list = new List<Document>();

            list.Add(doc);
            list.Add(doc1);

           RadGrid1.DataSource = list;
           RadGrid1.DataBind();

        }
    }
}

You can labels to the TemplateColumns and bind them as shown below
aspx:

<telerik:radgrid id="RadGrid1" runat="server" autogeneratecolumns="False" gridlines="None">
         <MasterTableView>
         <Columns>
         <telerik:GridTemplateColumn>
         <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"temp.Field1") %>'></asp:Label>
                    </ItemTemplate>
         </telerik:GridTemplateColumn>
         <telerik:GridTemplateColumn>
         <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"temp.Field2") %>'></asp:Label>
                    </ItemTemplate>
         </telerik:GridTemplateColumn>
         </Columns>
            ....

Thanks
Princy.
