RadGrid and ObjectDataSource

[David Tabatadze]

Hello.

I use RadGrid and ObjectDataSource (ods) to fill the grid with data.

I used to make insert, update and delete from code behind (using RadGrid events: UpdateCommand, DeleteCommand , etc) - so, i used to create my objects using FindControl(string id) and then manipulate with them.

Now, I decide to do this using ods, but i cannot work it out while i have nested objects.

(in case of single object it works fine - i mean if i Insert, Update or Delete only Person class - see below)

Here is my example:

class User{                                 class Person{
  int ID                                       int ID;
  int PersonID;                                string FirstName;
  string UserName;                             string LastName;
}                                           }

My ods methods are:

             SelectMethod: iList<User> GetUsers();
InsertMethod, UpdateMethod: void SaveUser(User u);
             DeleteMethod: void DeleteUser(User u);

In my EditFormTemplate i bind these like this (binding works fine):

<telerik:RadTextBox ID="txtUserName" runat="server"  Text='<%# Bind("UserName") %>'/>
<telerik:RadTextBox ID="txtFirstName" runat="server"
 Text= '<%# DataBinder.Eval(Container.DataItem, "Person.FirstName") %>' />
<telerik:RadTextBox ID="txtLastName" runat="server"
 Text= '<%# DataBinder.Eval(Container.DataItem, "Person.LastName") %>' />

So, when i am trying to update user object, updates only UserName, update does not cause to FirstName and LastName (User.Person properties). I guess ods cannot recognize them at all...

Is there any solution for this?

Or is there any alternative way to act situations lake this?

P.S. the same problem is when i use LinqDataSource

thanks.

Hello David,

Generally, Bind is used for two-way databinding and Eval - for one-way. The problem is that Bind cannot be used for nested objects.
You can either update the data manually, or use some of the workarounds listed below:

I hope this helps.

All the best,
