Silverlight组合框null项目高度

Question

I have following combobox:

    <ComboBox x:Name="cmb2" ItemsSource="{Binding SignCollection, Mode=OneWay}"/>

Sign Collection is List and its first element is null. My problem is that when i run my application all items shown normally but first one(which is null) has really small height(it's still there and selectable). So, my question is how can i force it to have same height as everything else.

Answer 1

Could you try this?

<ComboBox x:Name="cmb2" ItemsSource="{Binding SignCollection, Mode=OneWay}">
    <ComboBox.ItemContainerStyle>
         <Style TargetType="ComboBoxItem">
               <Setter Property="Height" Value="50"/>
         </Style>
    </ComboBox.ItemContainerStyle>
</ComboBox>

• 50: example fixed height

Hope it helps.
