Usercontrol in EditItemTemplate of templated control. How to achieve two-way databinding? - asp.net

Question

I was hoping to replace the EditItemTemplate of an ASP.NET ListView with a user control but I can't work out how to bind it to the data item in the ListView to achieve two-way data binding. The data item isn't a simple property. It's an object.
This seems only to give one-way Eval type databinding:
<EditItemTemplate>
<uc:MyUserControl id="thecontrol" runat="server" TheObject='<%# Container.DataItem %>'/>
</EditItemTemplate>
This gives an error:
<EditItemTemplate>
<uc:MyUserControl id="thecontrol" runat="server" TheObject='<%# Bind("Container.DataItem") %>'/>
</EditItemTemplate>
As does this:
<EditItemTemplate>
<uc:MyUserControl id="thecontrol" runat="server" TheObject='<%# Bind("this") %>'/>
</EditItemTemplate>
Is there some binding expression syntax to give two-way databinding to the current item in an EditItemTemplate?
Edit. This is the user control:
public partial class EditItemUserControl : System.Web.UI.UserControl
{
public TestObject TheObject
{
get
{
return new TestObject() { ID = Int32.Parse(hfID.Value), Name = txtName.Text };
}
set
{
hfID.Value = value.ID.ToString();
txtName.Text = value.Name;
}
}
protected void Page_Load(object sender, EventArgs e)
{
}
}

Just for reference. I was doing it wrong. A user control lives in the context of the page where it's rendered so there's no need to set a DataSource on it. In the .ascx file you can just use:
Text = '<%# Bind("MyProperty") %>'
or
Text = '<%# Eval("MyProperty") %>'
where MyProperty is some property of the parent control's DataSource.
