    Hi,

       I have a combo box in the edit Form in a radgrid. Im using Entity Framework and a business layer class to return an IEnumerable List
    <Employees> to bind to the grid. When the edit form comes up I want the titles and names of the employees to be shown in the combo box. like as the  DataTextField like :

    "{Title}:" + {FirstName}  + " " + {LastName}

    and I want to bind another property in the Employee class employee_Id as the DataValueField.

    Can someone show me how to do this, I am doing something similar in a GridCalculatedColumn where I am able to combine these multiple fields and show them in an expression like shown above. Please see Grid calculated column below. How can I bind the combo box like this so i can see the title: FirstName  Lastname  in the text field. Please note that I dont want a multi column grid as shown in this example here
    http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multicolumncombo/defaultcs.aspx  

    I want to show them all together. and be able to bind the employee_id property as the DataValueField so when i submit the form I can read that, can someone please show me how to do this in code, thanks.   Please see below for the CalculatedGridColumn where i am showing same information.

    <telerik:GridCalculatedColumn SortExpression="Employee.FirstName" HeaderText="Employees" AutoPostBackOnFilter="true"
     DataFields="Employee.Title,Employee.FirstName, Employee.LastName" Expression='{0}  + ":" + {1} + " " + {2}' >                        
     <HeaderStyle HorizontalAlign="Left" Width="30%" />
                             <ItemStyle HorizontalAlign="Left" />
                        </telerik:GridCalculatedColumn>

    Hello Farhan,
