是的,你可以在罗达塔·博恩(GredView)控制活动的一行中找到控制权,并赞同在密码上的必要活动。

void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {

    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      // Display the company name in italics.
      ((Checkbox)e.Row.FindControl("my_checkbox_id")).CheckedChanged += (sender, args) => {
          // do something in handler
      }

    }

  }

Dynamic controls support events only if them are re-created on each postback. So the only one solution is to continuously (on each postback) bind data to the gridview. If you have wrap gridview binding code by !IsPostback condition remove it and check after that.

顺便提一句,警告说,如果将改变电网数据来源数据,那么每个动态控制将产生新的独立信息数据库价值,这些控制活动将不予处理。

P.S. maybe the better approach is don t add controls into row dynaically but rather set Visible property value depending on data in DataItem. In this case you may have few server controls in ItemTemplate and show anly one of them.
