How to access ItemsControl from StyleSelector class

[Vic]

I'm testing out the RadGridView as a replacement for the standard wpf gridview I had been using.  I've got a complex row styleselector class which builds a style dynamically based on multiple criteria. I find that using the RadGridView I am no longer able to access the ItemsControl using ItemsControl.ItemsControlFromItemContainer(container) from within this class as it returns null.  I was using ItemsControl to determine is this was the first row in the collection.  Is there another alternative for identifying the first row in the collection from a styleselector?

Hello,

I would advise you to expose the data that would be used for conditional style selection through your business object, so that no access to visual objects should be needed. However, if you decide to stick to your former approach you can easily access the RadGridView instance like this:

public override Style SelectStyle(object item, DependencyObject container)
        {
            RadGridView radGridView = (container as GridViewRow).ParentOfType<RadGridView>();

            . . .

        }

Thanks for the advice Ivan.  You got me thinking in a new direction.  When building the object collection I will use a derived type for the first item that I can easily test for in the styleselector without increasing my memory footprint.
