Performance impact ItemTemplate resources

[johan-broekhof]

We have been using a couple of components as some kind of templates. In some of these components we needed to use converters and custom styles, which we defined in a resource dictionary inside the component. Does this have any performance impact? Should I move the contents of the component to the page and define the converters in the resource dictionary of the page? Does it even matter?

I have added a code example to illustrate the way we used the DataTemplate and our "component". Sometimes we would bind a couple of view model properties to the template as well.

<CollectionView.ItemTemplate>
    <DataTemplate>
        <templates:LeaderboardRowTemplate/>
    </DataTemplate>
</CollectionView.ItemTemplate>

I tried searching online but I couldn't find any source about this, or maybe I just didn't look hard enough.
