How to handle WPF event in MVVM for nested controls in a Window?

Usually I use an AttachedCommand Behavior which allows me to bind Events to ViewModel Commands. For example, you could use.

Change the data template to be a button that has a image as its content. Use the command and commandparameter properties on the button to call your printing method. You can declare your print command in your viewmodel, and bind to it.

Your parameter could be the selected row in your datagrid.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
