如何适当地设置数据表一个内在代码中有一个ObjectDataSource?

Question

我有一个ObjectDataSource ID的ObjectDataSource1在一个网页。我也有一个内在我结合采用的技术.ID的。DataSourceID.我的问题得到的是当文本改变在一个文本，该代码通话BrokerageTransactions.GetAllWithDt其返回一个数据表。我想设置这个数据表，作为数据库的内，但是它告诉我，我不能设置DataSouce和DataSourceId在一起。我如何能解决这个问题？代码如下。还。为什么你不能设置一个DataSourceID和一个数据源时使用ObjectDataSource?

谢谢， X

你有2个选择：

• 不用采用的技术在 所有。你只是使用的数据源 财产和设置，它在语法上 每一个时间。
• 你使用的DataSourceID财产的内，并添加2纯asp：参与默认值设定的。在ObjectDataSource_Selecting活动设置这些参数可以通过电子.InputParameters[]

希望这会有所帮助。
