How can I close OpenFileDialog by functions ok and cancel in MVVM pattern silverlight?

Question

I saw a lot of different information on this theme but nothing helped me.

1. How do u think? Probably better use a simpler pattern than MVVM with OpenFileDialog?
2. I have 2 functions Ok and Cancel. Each one has (this.DialogResult = true) or (this.DialogResult = false). I must make it in MVVM pattern. I am using value -> (bool cls = true) right now and bind it to DialogResult = {Binding cls} and change this property in different functions but it doesn't work. I get some exception.

Do you know how I can solve this problem with closing OpenFileDialog?

Answer 1

create as method here is something that may get you along the lines of what you are looking for

    void OpenDialogAction(object param)
    {
        //Add code here
        OpenFileDialog d = new OpenFileDialog();


        if (d.ShowDialog() == true)
        {
            //set your variable true
        }
        else
        {
            //set your variable false
        }
    }
