Hi
 
I'm trying to bind the buttons in the Dialog to a method but it seems always to go to  CanClose(Action<bool> callback) Method.
 
If  I call the Dialog with the following buttons yield return _dialogManager.ShowDialogAsync(addressEditor, new[] { "Previous", "Next", "Cancel" }); how do I get the buttons to call a  void Previous() or void Next() method in the Dialog VM?
 
Regards,
Joe

You can't do that with the DialogManager as-is. The buttons are designed to close the dialog with a certain DialogResult, not to trigger other actions in the dialog. If you want to build a wizard, you have two options:
1. Make Previous/Cancel part of addressEditor
2. Don't use the DialogManager and build the wizard yourself from scratch

BTW, you can pass an empty list of buttons to the DialogManager and  do all the buttons yourself in addressEditor, including the Cancel button.
 
You can then access the DialogHost from addressEditor as described in the following link and call IDialogHost.TryClose to close the dialog if the user clicks Cancel or "Finish".

Thanks for that.
 
If I pass an empty list of buttons to the DialogManager how would I simulate the Ok button behavior.
 
So in the parent VM I can access the properties of Dialog when I finish with it.
 

public IEnumerable<IResult> EditAddress(){

var addressEditor = _addressEditorFactory.CreatePart();

yield return _dialogManager.ShowDialogAsync(addressEditor, new List<DialogResult>() );

string test = addressEditor.MiddleName;

}

I figured it out.
