For example I have an object objA, which needs to be passed as a parameter to method in objectDataProvider. Further one of my text box control is bind to objA.
How can I achieve this by using the new markup?

The good news is that .NET 3.5 introduces a much better solution via its IDataErrorInfo support.

I have some problem when Binding a validation like this:

        <TextBox DockPanel.Dock=”Left” Width=”160″ Validation.ErrorTemplate=”{StaticResource validationTemplate}”>
          <Binding UpdateSourceTrigger=”PropertyChanged” >
            <Binding.ValidationRules>
              <val:AgeValidationRule  Min=”0″ Max=”180″ />
            </Binding.ValidationRules>
          </Binding>
        </TextBox>

but I want to set the next TextBox

These provide handy ways to look up named elements. But they will not work for unnamed objects or non-DOs. Nor will they work across namescopes.
