Hi,
Please always provide simple test sample which demonstrates the issue. It will allow us to answer very quick
ServerMapping is property contains server side path to extract data (it can be single name or several names are split by dot)
The following sample demonstrates how to extract data with ServerMapping (in this case department name will be serialized only) and Renderer with IsComplex (in this case, whole department object will be serialized)
<%@ Page Language="C#" %>
<%@ Import Namespace="System.Collections.Generic" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
var store = this.GridPanel1.GetStore();
store.DataSource = Employee.GetAll();
store.DataBind();
}
public class Employee
{
public int ID { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public Department Department1 { get; set; }
public Department Department2 { get; set; }
public static List<Employee> GetAll()
{
return new List<Employee>
{
new Employee
{
ID = 1,
Name = "Nancy",
Surname = "Davolio",
Department1 = Department.GetAll()[0],
Department2 = Department.GetAll()[0]
},
new Employee
{
ID = 2,
Name = "Andrew",
Surname = "Fuller",
Department1 = Department.GetAll()[2],
Department2 = Department.GetAll()[2]
}
};
}
}
public class Department
{
public int ID { get; set; }
public string Name { get; set; }
public static List<Department> GetAll()
{
return new List<Department>
{
new Department { ID = 1, Name = "Department A" },
new Department { ID = 2, Name = "Department B" },
new Department { ID = 3, Name = "Department C" }
};
}
}
