Hi there,

good to see the forum again.

In a BO I created a custom field property (Called "GridName2") according to the helpfile and I use this field via a Businessbindingsource in a DataGridView. So far so good. This property returns, depending on the type of adress (Private or Business) either the firstname or the department.

But when I click on the Column-Header of the DataGridView to sort this field, I get an error message (translated from german)

"Column Gridname2 was not found"

What could I have done wrong?

Thanks in advance

Thomas

Hi Trent,

this is what I wrote in the BO:

<Browsable(False), _

BusinessFieldDisplayInEditor(), _

Description("Wahlweise Vorname oder Name2"), _

DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _

Public ReadOnly Property [GRIDNAME2]() As System.String

Get

If Me.ADRESSTYP = "P" Then

Return Me.VORNAME

Else

Return Me.NAME2

End If

End Get

End Property

　

#End Region

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

'Return MyBase.GetCustomBindablePropertyDescriptors()

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

New MicroFour.StrataFrame.Business.ReflectionPropertyDescriptor( _

"GRIDNAME2", GetType(KundenBO))}

End Function

I can see no difference?

Thanks a lot and best regards

Thomas

Hi Thomas.

It looks like the Grid needs the datatable to have the column as of itself.

I created a sample that creates temporary fields on the table with the same name as the custom field, and was able to sort on it. See if it helps.
