[Solved] TwoWay binding whole DataItem in FormTemplate

[Softec]

Hi

How can I bind the whole Container.DataItem to my Control in the FormTemplate? I have a UserControl for editing my object (in this case Person) and would like to reuse this in the EditFormSettings of the RadGrid but can't achieve this in a TwoWay mode. 

My code so far:

  <EditFormSettings>
                <FormTemplate>
                    <uc:GridButtons ID="GridButtons2" runat="server" Position="Top" />
                        <data:PersonPanel runat="server" ID="PersonPanel" DataSource='<%# Container.DataItem %>'
                            AddCss="panel" GroupingText="Personendaten"  />
                    <uc:GridButtons ID="GridButtons1" runat="server" Position="Bottom" />
                </FormTemplate>
            </EditFormSettings>

GridButtons is just a UserControl with the Edit/Canel buttons (top and bottom) whereas PersonPanel is my control which takes a Person object and gives a Person object back (DataSource Property). The Propblem is that the Container.DataItem expression is only OneWay, how could I achieve this in both ways so the RadGrid gets the updated Object back?

Thanks for help!

I solved it by creating a property on my class which represent itself and copying the needed properties in the set accessor, a little bit ugly but this was the fastest way to achieve this...

Now i can bind to the Self property

Markup:

 <EditFormSettings>
                <FormTemplate>
                    <uc:GridButtons ID="GridButtons2" runat="server" Position="Top" />
                        <data:PersonPanel runat="server" ID="PersonPanel" DataSource='<%# Bind("Self") %>'
                            AddCss="panel" GroupingText="Personendaten"  />
                    <uc:GridButtons ID="GridButtons1" runat="server" Position="Bottom" />
                </FormTemplate>
            </EditFormSettings>

Dummy code:

public class Person
{
  public Person Self
   {
     get { return this; }
     set
     {
         // copy the needed properties
     }
}
