Is there such a property in xaml to bind to the property when the application starts?

Question

WPF

Suppose there is such a property

public TCommand ReadDataBase
        {
            get
            {
                return new TCommand
                (
                    (obj) =>
                    {
                        UserList = DataBaseOperations.ReadDataBase();
                    }
                );
            }
        }

is there something in the xaml that could execute it on application startup?

Answer 1

Do not make such saints.
Make St. like this:

public MyClass()
{
    MyCommand = new DelegateCommand(AnyAction);
}

public ICommand MyCommand {get;}

void AnyAction()
{
    //code
}

Then you can call the AnyAction method from the constructor, or get the ViewModel in the View and call MyCommand.
