ASP.NET Webforms - JQGrid Populate Data with ObjectDataSource (Object in Object) -

here's try jqgrid :

<jq:jqgridcolumn                  datafield="id"                  primarykey="true"                 datatype="int"                 headertext="no"                  width="60" />             <jq:jqgridcolumn                  datafield="customerid.name"                 datatype="string"                 headertext="customer name"                  width="100" />             <jq:jqgridcolumn                  datafield="customerid.surname"                  searchable="false"                 datatype="string"                 headertext="customer surname                  width="100" /> 

and objectdatasource class :

public class order { private int id; private customer customerid;  public customer customerid         {             { return customerid; }             set { customerid = value; }         }          public int id         {             { return id; }             set { id = value; }         } } 

and customer class order class. when try it's giving error :

the column datafield=customerid.name not exist in datasource. (but does)

how can solve ? thanks.

i've got answer :

public string customername         {             { return customerid == null ? "" : customerid.name; }         } 

if needs, use it.
