DSL Tools: Center a shape in the diagram

I'm developing a DSL. In the main window, I have two panes ( Panel ): on one, a listbox of the diagram , and on the other the diagram itself. I would like to click on an item in the list to center the corresponding shape on the screen.

I do not want to move the shape to the center of the diagram by changing its x, y coordinates. I want to roll the diagram to center the shape

Another way to explain: When a validation error occurs (Errors window at the bottom), and when you click on the error, it centers invalid shape on the screen, right? This is what I want.

Starting point:

private void symbolsListBox_SelectedIndexChanged(object sender, EventArgs e)
{
    var listBox = sender as ListBox;
    var symbol = listBox.SelectedItem as Symbol;
    var compartment = PresentationViewsSubject.GetPresentation(symbol)
        .FirstOrDefault() as SymbolCompartmentShape;
    var diagram = docView.CurrentDiagram;

    //Next step, center the shape
    //How? God please help me!!!
}

The example with image is always better !! so ...
