简单的绑定

 protected void gvOrder_RowDataBound(object sender, GridViewRowEventArgs e)

    {

        if (e.Row.RowType == DataControlRowType.DataRow)

        {



           GridView gvDetail = e.Row.FindControl("gvDetail") as GridView;

           if (gvDetail != null)

           {

               gvDetail.DataSource = GetDetailsByOrderId(gvOrder.DataKeys[e.Row.RowIndex].Value.ToString());

               gvDetail.DataBind();

           }

        }

你知道咯撒？[Quote=引用 8 楼 dongdgh 的回复:]
6楼的代码是可以实现的GridView 嵌套GridView第二个GridView 他是先绑定第一个GridView ，点击第一个GridView 一列得在事件里面找到这个已经嵌套的GridView 可以直接在事件里面绑定。支持6楼的！

OnRowDataBound事件,与1.x中的ItemDataBound有一腿.
