I have a Form where I am trying to use 2 Custom Fields. One works as it should the other does not?

I have attached a picture showing that the Custom Field shows up in the BO Visualizer and a picture showing that it does Not show up in a MessageBox nor a Bound Text box???????

Here is my Custom Field Code:

Protected Overrides Function GetCustomBindablePropertyDescriptors() As MicroFour.StrataFrame.Business.FieldPropertyDescriptor()

Return New MicroFour.StrataFrame.Business.FieldPropertyDescriptor() { _

New MicroFour.StrataFrame.Business.ReflectionPropertyDescriptor("Cowboy_Name", GetType(MyBaseRoughStockBO)), _

New MicroFour.StrataFrame.Business.ReflectionPropertyDescriptor("Cowboy_InvertedName", GetType(MyBaseRoughStockBO)), _

New MicroFour.StrataFrame.Business.ReflectionPropertyDescriptor("PRCANUM", GetType(MyBaseRoughStockBO))}

End Function

<

Browsable(False), _



BusinessFieldDisplayInEditorAttribute(), _Description("PRCA Number"), _

DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _

Public ReadOnly Property PRCANUM() As String

Get

' Return MyBase.RequiredFields

If Me.CurrentDataTable.Columns.Contains("Membershipcd") Then

If Not TypeOf (Me.CurrentRow.Item("membershipcd")) Is DBNull Then

Return CStr(Me.CurrentRow.Item("membershipcd")) + Me.CurrentRow.Item("membershipnumber").ToString

Else

Return ""

End If

Else

Return ""

End If

End Get

End Property

 

I'm Sorry I can not get the last part to format correctly? This is the Custom Field that Shows in the BO but not in the MessageBox nor the Bound Text Box?

TIA.

 

 

   

Hi Terry,

So the problem is that it is not showing in a listview?

I believe my previous explanation has a lot to do because it is a calculated field as such the CFP will only contain data when the source SELECT returns the data for it.  With listview it could be tricky in a sense of how you are loading its data ex ParentFormLoading VS manually loading.  I love SF ListViews, but I learned in a hard way that it is a good idea to have control on when to load the data (lv.Refresh()), so in the listview Populate data settings I always use a copy data from bo and manually drop a BO instance in the form, assign it to the list view and fill this BO manually then refresh the listview.

Now if after reviewing my suggestions still you don't get it to work, please create a small VB sample project using one of the SF Sample database tables that would duplicate the issue and upload it here, I will gladly take a look and make it work or if you prefer, I can do one remote support session to take a look at the issue on hand with your project, feel free to email for connection details.

Edhy I put a Break on the Get and I must have changed something else because it is working. I have NO IDEA why. I did delete some of my code and put some of your code into play and so I am sure I had some weird character in my code that your code fixed.

Thanks so much.

I don't believe how much time I spent chasing a mystery....!

Hi Terry,

Glad it is working out.

Well after all of this. I was getting an error every not and again so it was time to delete the whole form and start again. Even started with a little older version of the project. Everything seems to work now so I am really not sure about any of the problems I was having.

Just a bug in the night I think.
