I need to display multiple instances of a basketDetailsView.xaml within a region placed in basketView.xaml, but I'm getting the following errormessage when i debug my code:
"An exception occurred while creating a region with name 'basketRegion'. The exception was: System.InvalidOperationException: ItemsControl's ItemsSource property is not empty. This control is being associated with a region, but the control is already bound to something else. If you did not explicitly set the control's ItemSource property, this exception may be caused by a change in the value of the inherited RegionManager attached property"
The basketView XAML contains an ItemsControl tag defined like this
<ItemsControl x:Name="basketItemsControl"cal:RegionManager.RegionName="basketRegion"/>
The view also has a listbox where I can uncheck/check the BasketDetailsViews I want to look at:
<ListBox x:Name="basketListBox" ItemsSource="{Binding basket}" MinWidth="200">
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox commands:Checked1.Command="{Binding DataContext.CheckCommand,ElementName=basketListBox}" Content="{Binding basketName}" ></CheckBox>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox
When I run without debugging it executes fine and I can pop in/out the different basketDetailsViews, but when debugging the above mentioned error shows. What Am i doing wrong?
EDIT:
Public Sub AddCageDetailsView(ByVal BasketName As String)
Dim basketRegion = _RegionManager.Regions("basketRegion")
Dim view = _Container.Resolve(Of basketDetailsView)()
Dim viewmodel = _Container.Resolve(Of basketDetailsViewModel)()
view.ApplyModel(viewmodel)
basketRegion.Add(view)
End Sub
So basketRegion is the region in my ItemsControl as specified above. This region is supposed to hold my basketDetailsViews..
