我在网页上有一个ID为ObjectDataSource1的ObjectDataSource。我还有一个gridview,我将ObjectDataSource.ID绑定到GridView.DataSourceID。我得到的问题是在文本框中更改文本时,代码调用BrokerageTransactions.GetAllWithDt返回DataTable。我想将此数据表设置为GridView的DataSource,但它告诉我,我无法将DataSouce和DataSourceId设置在一起。我怎样才能解决这个问题?代码如下。也。为什么在使用ObjectDataSource时无法设置DataSourceID和DataSource?
谢谢, X

dtTransFrom = Convert.ToDateTime("1/1/1900");
dtTransTo = Convert.ToDateTime(txtTransactionsTo.Text);
}
//TransactionsFrom Box and TransactionsTo Box is Not Empty
if ((txtTransactionsFrom.Text.Length > 2)

{
dtTransFrom = Convert.ToDateTime(txtTransactionsFrom.Text);
dtTransTo = Convert.ToDateTime(txtTransactionsTo.Text);
}
// Fails Here
grvBrokerage.DataSource =
BrokerageTransactions.GetAllWithDt(brokerageaccountdetails.BrokerageId,
dtTransFrom,
dtTransTo);
grvBrokerage.DataBind(); }
