Default value for comboBox

Question

Hi I try set default value for comboBox.

XAML:

Answer 1

You do not need to create your own empty string, string has a static field for that, so you could set it in the style like this:

Value="{x:Static System:String.Empty}"

And why don't you just use a normal setter in your style right away?

<Style x:Key="statusComboStyle" TargetType="{x:Type ComboBox}">
    <Setter Property="SelectedIndex" Value="0"/>
</Style>

(You should make sure that there is at least one item in the ComboBox)

Answer 2

Binding="{Binding Path=Name.Length, FallbackValue=0, TargetNullValue=0}" Value="0">
