Hello,

when I bind the TaskSource of the RadGanttView (WPF) to a CompositeCollection I get the Exception "Object of Type System.Windows.Data.CollectionContainer cannot be converted to Type IGanttTask". With the RadTreeView it works. All Items in the Collections implements IGanttTask.

<CompositeCollection x:Key="ProjectChildCollection"><br>               
<CollectionContainer Collection="{Binding DataContext.SelectedProject.ProjectActions, Source={x:Reference control}}" /><br>               
<CollectionContainer Collection="{Binding DataContext.SelectedProject.Tasks, Source={x:Reference control}}" /><br>               
<CollectionContainer Collection="{Binding DataContext.SelectedProject.ResourceBookings, Source={x:Reference control}}" /><br>           
</CompositeCollection>

 

TasksSource="{Binding Source={StaticResource ProjectChildCollection}}"

Hi Helmut,

In its current implementation RadGanttView does not support binding the TasksSource to CompositeCollection. You could log this as a feature request in our Feedback Portal. We will review the item and we will consider it for implementation.

Hope this information will be helpful for you.
