Question

我有一个部分类（主类是LinqToSql生成的类）

   <DataObject(True)> _
Partial Public Class MBI_Contract

    <DataObjectMethod(DataObjectMethodType.Select, True)> _
   Public Shared Function GetCancelableContracts(ByVal dealer As Dealer) As List(Of MBI_Contract)
        Return Utilities.GetCancelableContractsForDealer(dealer)
    End Function
End Class

这是它正在调用的方法

Public Function GetCancelableContractsForDealer(ByVal dealer As Dealer) As List(Of MBI_Contract)
        Dim db As TestDataContext = TestDataContext.Create()
        Return (From mbi As MBI_Contract In db.MBI_Contracts _
                                 Where mbi.MBI_DealerNumber = dealer.DealerNumber _
                                 AndAlso mbi.MBI_PaidFor = True _
                                 AndAlso mbi.MBI_Deleted = False).ToList()
    End Function

我想使用ObjectDataSource来驱动DropDownList。

  <asp:ObjectDataSource ID="contractOds" runat="server" 
         TypeName="MBI_Contract"
         SelectMethod="GetCancelableContracts" 
         DataObjectTypeName="Dealer">
    </asp:ObjectDataSource>

我的aspx页面有一个在BasePage中设置的Dealer属性。我的问题是如何将此属性（对象）传递给ObjectDataSource，因此可以在我的select方法中进行评估。有谁知道我怎么做到这一点？或者我完全以错误的方式做这件事？

感谢任何建议，干杯，〜在圣地亚哥

Answer 1

Protected Sub contractOds_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs) Handles contractOds.Selecting
    e.InputParameters.Insert(0, "dealer", Dealer)

End Sub

这似乎有效。

ObjectDataSource DataObjectTypeName帮助。传递对象作为参数
