Conditional List itemtemplate or datatemplate in WPF

Question

This may be an obvious question, but I think there may well be multiple ways to implement it, so not only will this be useful to me, hopefully it will be useful to others.

Answer 1

One option is to create a DataTemplateSelector in your code:

public class QueueDisplayDataTemplateSelector : DataTemplateSelector
{
    public override DataTemplate SelectTemplate(object item, System.Windows.DependencyObject container)
    {

        var listBoxItem = item as JobQueueListBoxItem;
        var resourceName = String.Empty;
        switch (listBoxItem.JobQueueListBoxItemType)
        {
            case JobQueueListBoxItemType.QueuedJob :
                resourceName = "DataTemplateQueuedJob";
                break;
            case JobQueueListBoxItemType.TransferWorker :
                resourceName = "DataTemplateTransferWorker";
                break;
            default:
                throw new InvalidOperationException(string.Format("There is no corresponding list box template for {0}", listBoxItem.JobQueueListBoxItemType));
        }
        var element = container as FrameworkElement;
        return element.FindResource(resourceName) as DataTemplate;
    }
}

This would then be declared in your XAML as a resource

And then you would assign this to you list box:
