Question

I have an enum like:

enum Gender
{
   Male = 1,
   Female = 2
}

Then I have a Combobox binding to a list of Gender.

<ComboBox ItemSource = 'Binding GenderList, Mode=TwoWay,
                        UpdateSourceTrigger=PropertyChanged'
          SelectItem = 'Binding SelectedGender' />

When user opens the view, how can I make ComboBox selection default to blank? Then after user made a selection, the blank selection is removed from the ComboBox source.

Thanks

Thanks all the replies. I fixed my problem by manully assigning the selected item to null.

What you are describing is the default behavior of the ComboBox. You don’t need to do anything (except for correct the typos in your XAML. It should look like:

<ComboBox ItemsSource="{Binding GenderList}" SelectedItem="{Binding Path=SelectedGender}" ></ComboBox>
