WPF Datagrid multiple SelectedItems in MVVM

I can assure you: SelectedItems is indeed bindable as a XAML commandparameter

After a lot of digging and Googling, I has finally found a simple solution to this common issue.

Must follow all the following rules:

1. Following Ed Ball's suggestion ', on you XAML command databinding, define CommandParameter p Roperty before Command property. This a very time-consuming bug.

2. Make sure your ICommand ' s canexecute and Execute methods has a parameter of object type. This is the can prevent silenced cast exceptions that occurs whenever databinding Commandparameter type does not match your command method ' s parameter type.

   Private bool Ondeleteselecteditemscanexecute (object SelectedItems)
   {

    //Your goes heres  pre> 
   } 
    
    Private bool Ondeleteselecteditemsexecute (object SelectedItems) 
    {
    
    //Your goes here S  
    
   } 
    

For example, you can either send a Listview/listbox ' s selecteditems the property to you ICommand methods or The Listview/listbox it self. Great, isn ' t it?

Hope It prevents someone spending the huge amount of time I did to figure out how to receiveSelectedItems as CanExecute parameter.
