急！！！！动绑定GridView和DetailsView问题

Question

    public void bind() {        OracleConnection conn;
        String constr = "Data Source=DPLIS;User Id=deppon009;Password=dplis009;";
  
        conn = new OracleConnection(constr);
        conn.Open();
        OracleDataAdapter thisAdpater =
                new OracleDataAdapter("select * from t_myp_booktype", conn);
        DataSet ds = new DataSet();        thisAdpater.Fill(ds, "booktype");
        DataTable dt = ds.Tables["booktype"];        GridView1.DataSource = ds.Tables[0];
        GridView1.DataBind();
        DetailsView1.DataSource = ds.Tables[0];
        DetailsView1.PageIndex = GridView1.SelectedIndex + GridView1.PageSize * GridView1.PageIndex;
        DetailsView1.DataBind();
        
    }但是当点击按钮时，detailsView显示的是点击上一个GridView对应的数值 
怎么回事？

Answer 1

点击上一个GridView对应的数值,是什么意思

Answer 2

GridView1.DataSource = ds.Tables[0]; 
        GridView1.DataBind(); 
        DetailsView1.DataSource = ds.Tables[0]; 
        DetailsView1.PageIndex = GridView1.SelectedIndex + GridView1.PageSize * GridView1.PageIndex; 
        DetailsView1.DataBind(); 
两个连在一起写？那在GridView1.DataBind(); 后  GridView1.SelectedIndex 应该不会变的
跟踪一下GridView1.SelectedIndex + GridView1.PageSize * GridView1.PageIndex;
还有在selectchange事件中绑定 DetailsView1
DetailsView1.DataSource = ds.Tables[0]; 
        DetailsView1.PageIndex = GridView1.SelectedIndex + GridView1.PageSize * GridView1.PageIndex; 
        DetailsView1.DataBind(); 

Answer 3

基本没什么,以下试试!!
DetailsView1.PageIndex = GridView1.SelectedIndex +1 + GridView1.PageSize * GridView1.PageIndex; 

Answer 4

将DetailsView1单独绑定就OK L了

Answer 5

UP。添加个SqlDataSource，指定<SelectParameters>
                <asp:ControlParameter ControlID="GridView" Name="ID" 
                    PropertyName="SelectedValue" />
            </SelectParameters>和查询方法
