WPF/MVVM: SelectedIndex Binding Property not updating when Combobox Selection Changed

Question

I\'ve got a very similar question to Jinesh\'s. I need to get the value of the SelectedIndex (or SelectedItem or SelectedValue) of a combo box in to my ViewMode

Answer 1

The property getter ignores the previously set value and always returns the index of the current month.

The declaration should look like this:

private int monthIndex = DateTime.Today.Month - 1;

public int MonthIndex
{
    get { return monthIndex; }
    set
    {
        if (monthIndex != value)
        {
            monthIndex = value;
            RaisePropertyChanged("MonthIndex");
        }
    }
}
