WPF ComboboxItems with button - wpf

Question

I have created my own combobox style along with stylign combobox items. The dropdown needs to display some items with buttons and others without my items are created dynamically as follows:
ComboBoxItem typeItem = new ComboBoxItem();
typeItem.Content = "Test";
typeItem.Tag = i;
MyCombobox.Items.Add(typeItem);
My question is how do I apply this style to some items and not others, my two comboboxitems are bellow?
<Style x:Key="{x:Type ComboBoxItem}" TargetType="{x:Type ComboBoxItem}">
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="MinHeight" Value="{DynamicResource ResourceKey=MinimumIteractSizeDips}" />
<Setter Property="MinWidth" Value="{DynamicResource ResourceKey=MinimumIteractSizeDips}" />
<Setter Property="Foreground" Value="Black"/>
</Style>
<Style x:Key="MyComboBoxItem" TargetType="{x:Type ComboBoxItem}">
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="MinHeight" Value="{DynamicResource ResourceKey=MinimumIteractSizeDips}" />
<Setter Property="MinWidth" Value="{DynamicResource ResourceKey=MinimumIteractSizeDips}" />
<Setter Property="Foreground" Value="Black"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ComboBoxItem">
<Grid>
<Label Content="{TemplateBinding Content}" Foreground="Black" Background="White" Height="26" HorizontalAlignment="Left" VerticalAlignment="Center" Grid.Row="0" Grid.Column="0"/>
<Button Grid.Column="2" Grid.Row="0" Content="Settings" Height="23" HorizontalAlignment="Left" Margin="2" Name="PositionSettings" VerticalAlignment="Center" Width="57"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Answer 1

Check the StyleSelector class.
public class MyStyleSelector : StyleSelector
{
public override Style SelectStyle(object item, DependencyObject container)
{
var element = container as FrameworkElement;
var myVm = item as MyViewModel;
if(myVm.EditMode)
return element.FindResource("TemplateWithButtons") as DataTemplate
return element.FindResource("TemplateNormal") as DataTemplate
}
}
and in xaml, define a resource for your selector
<MyStyleSelector x:Key="myStyleSelector"/>
and apply that to your combobox.
<ComboBox StyleSelector="{StaticResource myStyleSelector}"/>
btw. x:Key with the same type as TargetType is redundant.
Final Note: You should not override the style for that. What you want is DataTemplate and the DataTemplate selector. Also you should not bind the Content(type object) to a labels text (type string), a ContentPresenter is the way to go here.
