| Yes, I build all the project to test it, I tested with some BOs and same error....
I have an CRUD working, when I press the "copy" button with the last post code, the message appears:
NotImplementedException
The class [MicroFour.StrataFrame.Business.BusinessLayer] must override the property 'TableName' since it derives from MicroFour.StrataFrame.Business.BusinessLayer.

I tested to declare _CopyBO as BusinessObject (ej: as TESTBO1) instead of "as bussinesslayer" and It worked partially...it copy the datatable..... but I have the properties of testBO1, not the actual me.PrimaryBusinessObject BusinessObject, the unique thing that I see that I can do is to declare _copyBO as [theCorrectTypeBO here], not other solution to copy the current row to call it back later like "me.primarybusinessobject.someFieldOnSqlProperty = _copyBO.someFieldOnSqlProperty"
I think that the best I can do to copy the actual record from some BO is to copy the current dataRow and restore it later... Any best idea? :/
Thanks for all |

| | Yes, this message is because the partial class has not been built. When we create the partial class for the BO we automatically overwrite the TableName property, which on the BO you are referring does not have it overwritten so thus you get the error. If you HAve built your partial class then something else is going on. Can you post your partial class file here. It will be the MyBo.Designer.vb file. |

I think that the problem is that I like to create the copy of a (unknown yet on design) new business object (I trying to create a generic CRUD) and can´t use the businesslayer to define the type of _CopyBO" because it don't override the tablename property :S I not sure how to avoid this problem and copy a single record from the primarybusinessobject into a temporal 1-row business object copy, I don´t known how I can declare the _copyBO as same type that
myform.primarybusinessObject, sometype like:
dim _copybo as gettype(me.primarybusinessobject) '<---- something like this exist on VB?
Thanks and sorry for my bad english and all my newbie questions
--------------------------------------------
I repeat the code that I posted before
My "full" code:
--------------
Private _CopyBO As New MicroFour.StrataFrame.Business.BusinessLayer
Dim sFiltroAnterior As String = Me.PrimaryBusinessObject.Filter
Dim _CurrentRowIndex As Integer = Me.PrimaryBusinessObject.CurrentRowIndex
Me.PrimaryBusinessObject.Filter = Me.PrimaryBusinessObject.PrimaryKeyField & " = " & Me.PrimaryBusinessObject(Me.PrimaryBusinessObject.PrimaryKeyField)
'-- at this line the "tablename" error ocurrs
_CopyBO.CopyDataFrom(Me.PrimaryBusinessObject, MicroFour.StrataFrame.Business.BusinessCloneDataType.ClearAndFillFromCompleteTable)
Me.PrimaryBusinessObject.Filter = sFiltroAnterior
Me.NavigateToPrimaryKey(_RegistroEnMemoriaBO(_RegistroEnMemoriaBO.PrimaryKeyField)) |

| Fabian,
I think that the code posted won't have just one record (unless the primary BO only has one record). When you do the CopyDataFrom, you need to supply the ClearAndFillFromDefaultView option to get just the filtered records.
Of course, if what you do have works, I'm not understanding what's happening  |

| Yep, Greg is correct... if you filter out all but 1 row, and you want to copy just that one row, then you will need to use the ClearAndFillFromDefaultView. The other option (ClearAndFillFromCompleteTable) will ignore the filter you set on the business object.
