Can you interrupt the established ownership procedure

Question

I am programming in C # .NET. Is it possible to interrupt the established procedure of a class property without exception?

Here is what I want to do ...

public int RandomProperty
{
    set
    {
     DialogResult answer = new DialogResult();
     answer = MessageBox.Show("This process could take up to 5 min. Are you sure you want to continue?");
     if(answer = DialogResult.No) 
        CancelSet   // Can I do something similar here?
     else
     {
      ...Do set procedure
     }
    }
}

I don’t think I can use a method (instead of a property) because I set this value using the grid property.
