ListView/GridView ItemContainerStyleSelector not working

Question

Hey Guys,

I've been trying to figure out why ItemContainerStyleSelector isn't working on any Item type control. I simply made a class, CustomStyleSelector, that extends StyleSelector. CustomStyleSelector::StyleSelectStyle() returns a ref new Style(). It builds and runs, but when I set a breakpoint in the SelectStyle method I found it the method never gets called. I tired this on a ListView and GridView and neither work.

Is there some prerequisite to using the ItemContainerStyleSelector?

Answer 1

Can you post an example of how you are assigning the CustomStyleSelector to your ItemsControls?

Answer 2

Hey Jason,

I've tried all of these methods:

<UserControl.Resources>
    <local:CustomStyleSelector x:Key="CustomStyleSelector">
<UserControl.Resource>

<StackPanel>

    <ListView ItemContainerStyleSelector="{StaticResource CustomStyleSelector}">
        <x:String>Item 1</x:String>
        <x:String>Item 2</x:String>
        <x:String>Item 3</x:String>
    </ListView>

    <ListView ItemContainerStyleSelector="{StaticResource CustomStyleSelector}">
        <ListViewItem>Item 1</ListViewItem>
        <ListViewItem>Item 2</ListViewItem>
        <ListViewItem>Item 3</ListViewItem>
    </ListView>

    <ListView ItemContainerStyleSelector="{StaticResource CustomStyleSelector}" ItemsSource="{Binding Items}">
    </ListView>

</StackPanel>

Neither of them appear to work.
