Validation Question

I have your validators working correctly on the screen and they work well.

My problem is when validation errors are present, I wish to disable the Save Button by return FALSE from a CanSaveCommand method in my view model.

Can you please suggest how to do this.  It is not obvious how to do this.

Hi Tom,

Can you give me some more details - or even better an example project that shows the problem you are having and what you'd like to do?  I'm not sure I completely understand your goal - it seems like you could just have a "validationOK" field on your ViewModel that you trip and it is checked on all the CanExecute handlers that require validation - but I'm sure you've tried that.

I have not tried that solution, but I found ValidationManager.Validate(this,null) method.  I called that in SaveCanExecute handler and it solved my problem.
