Hello Elena.

Here is a running project.

It is reduced by only the most important to include.

I need help in the class "MyDialogHelper" Category button.

The class "MyAppointmentDialogCore" is necessary for me.

The Appointment window is much more complicated in the real project but it's all about the button so I have taken only the default.

And as always, sorry for the bad English;-)

Thank you

Hello Marcus,

Thank you for the sample. I modified in by changing the type of the Categorize button to MenuTool and I have added a child menu named “Add items”. In the handler of the PreviewMosueDown I display the ActivityCategoryDialog as follows:

For additional reference on this approach please take a look at the attached sample.

If you have any additional questions or concerns with this matter please feel free to let me know.

    Private Sub menuTool_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)
        Dim activitylist As New List(Of ActivityBase)()
        activitylist.Add(_activity)
        Dim menuTool As ToolMenuItem = TryCast(sender, ToolMenuItem)
        Dim owner As AppointmentDialogCore = TryCast(menuTool.Tag, AppointmentDialogCore)
        Dim activityCategoryHelper As ActivityCategoryHelper = New ActivityCategoryHelper(_dataManager, activitylist, owner)
        Dim closingCallback As Func(Of Boolean)
        Dim closedCallback As Action(Of Nullable(Of Boolean))
        _dataManager.DisplayActivityCategoryDialog(_ribbonWindow, Nothing, activityCategoryHelper,
 closingCallback, closedCallback)       

    End Sub

Hello,

I have been reading through your correspondence so far and I cannot seem to understand what exactly are you asking and where does this screenshot come from. Please elaborate on that so I may try and look for a solution.

Thanks in advance. Looking forward to hearing from you.

I want to display the entries of the lists for the existing categories (in my example picture test x)

In case I use your standard dialogue these are generated automatically. These are intern objects of the type "CategoryListItems".

But if I use the example of your colleague which was generated on the 22th of June, 2012 I have to generate the objects in the code by myself.

And this is the problem: I wasn´t able to generate objects of the type "CategoryListItems".

How do I have to proceed?

Hi Petar,

I think it would be helpful for many (and would save time) if the collection would be public.

Thanks for your support.

Hi Marcus, 

Excuse me, I had missed your reply from the 12^th. I have been looking into this and wasn’t able to find any built-in functionality rather than the one I already suggested. I can again suggest you inherit from ScheduleDialogFactory where the Categories functionality is already implemented, or if you want I can submit a new Product Idea on your behalf so that such collection might get available in a future volume release of ours. 

Looking forward to hearing from you.

Hello Petar,

Unfortunately, their solution brings me no no more (see my posting 07/12/2012).

Your example gives me a "Category" Object not a "CategoryListItems" Object.

Is there a function that gives me instances of "CategoryListItems"?

Thank You
