The event hancler below doesn't work in VWD 2010 Express. A duplicate data causes an error but it stops in the Business Logic Layer. It works fine in Visual Studio 2008. Please help if I am missing something?
Protected Sub ObjectDataSource1_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceStatusEventArgs) Handles ObjectDataSource1.Inserted
If e.Exception IsNot Nothing Then
If e.Exception.InnerException IsNot Nothing Then
Label1.Text = e.Exception.InnerException.Message
e.ExceptionHandled = True
End If
End If
End Sub
The ODS Control:
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
InsertMethod="InsertPerson" SelectMethod="GetPerson" TypeName="Person">
<SelectParameters>
<asp:QueryStringParameter Name="id" QueryStringField="id" Type="Int32" />
</SelectParameters>
<InsertParameters>
<asp:Parameter Name="PersonName" Type="String" />
</InsertParameters>
</asp:ObjectDataSource>
The BLL:
Public Class Person
...
Public Shared Function InsertPerson(ByVal personName As String) As Integer
Return SqlProvider.AddPerson(personName)
End Function
Public Shared Function GetPerson(ByVal id As Integer) As Person
Return SqlProvider.GetPerson(id)
End Function
End Class
The DAL:
Public Class SqlProvider
Public Shared Function AddPerson(ByVal name As String) As Integer
Dim cn As SqlConnection = New SqlConnection( _
ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
Dim cmd As SqlCommand = New SqlCommand("INSERT INTO person(name) VALUES(@name)", cn)
cmd.Parameters.AddWithValue("@name", name)
cn.Open()
Return cmd.ExecuteNonQuery()
End Function
...
End Class
Execution stops in the line (DAL):
Return cmd.ExecuteNonQuery()
PLEASE HELP! I'm stuck!
