在gridview的RowDataBound事件中创建的控件如何取值

不用这样吧，直接设置成模板列，把编辑行设置成dropdownlist，然后再在RowDataBound事件中的编辑行对dropdownlist进行绑定，和设置当前值

代码比较长，呵呵///edit2.aspx.csusing System;

// 得到当前的行对象
   GridViewRow row = GridView1.Rows[e.RowIndex];
1)普通列
  (控件类型)GridViewRow.Cells[索引].Controls[索引]
2)模板列
  (控件类型)GridViewRow.FindControl("控件ID")

((DropDownList)(GridView1.Rows[e.RowIndex].FindControl("要找的ID"))).SelectedIndex这样！！！

调试了下，发现不是取不到值，还是点了更新后，在GridView1_RowUpdating事件里，自已在GridView1_RowDataBound中new的textbox不见了

在rowcreate中new控件，在rowdatabouand中绑定数据,搞定了
