Bug in dataset.merge???

[Guest]

Well, is this a bug or is it just really late

here is an example

Dim DS1 As New DataSe
Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Clic
Dim DS2 As New DataSe
Dim Cdt As New ClassicData.DataTabl
Cdt.TableName = "test
Cdt.Columns.Add(New DataColumn("Hello")
Cdt.IsMasterTable = Tru
DS2.Tables.Add(Cdt

DS1.Merge(DS2

Dim cdt2 As ClassicData.DataTabl
cdt2 = DS1.Tables(0
MsgBox(cdt2.IsMasterTable
End Su

of course classicdata.datatable is a custom version of the datatable, it inherits datatable and all I did was add one property (ismaster)

Now the property is set to true and after the merge it's false

I of course have a much more enhanced datatable and datacolumn and any properites they may have set get set to the default when the merge is done

What's going on here?

Hi Joe,

Merge merges just Rows and nothing more.
It will ignore your class' added fields.
