Validation with Button

[angelru]

I am having a hard time validating

I have a custom control with a frame, multiple tags, and an input. I have managed to add the validation for that input, but I can't tell when everything is validated through a command. I have added the click event in the codebehin and there I do the validation, then I run my Command, but all the input values are always null. If in my button I remove the click event and bind the command, everything works fine (without validation), how can I see in my Command if everything went well?

I am facing the same issue. There is no validation at command level.

Is the CanExecute delegate, in Command ctor helpful?
