Gridview dynamic update w/ SqlDataSource

Question

I have a SqlDataSource that updates whenever a user specifies a value. I'm trying to do the following to update the gridview as well, but the gridview won't show anything. Did I miss anything here?

private void updateSessionGridView(string p)
{
    session.SelectCommand = @"SELECT TOP 10  * FROM [MyDB]
                                    where key = '" + p + "'";
    GridView1.DataSourceID = null; 
    GridView1.DataSource = session;
    GridView1.DataBind();
}

如果使用的是数据源控件，则需要设置DataSourceID属性，而不是DataSource属性。
