谁能解释下这段代码
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string PlacePK = Request["PlacePK"].ToString();
LinkButton linkbutton = (LinkButton)e.Row.Cells[3].FindControl("lBtnSelect");
linkbutton.CommandArgument = e.Row.RowIndex.ToString();

}

}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{

if (e.CommandName == "select")
{
string PlacePK = Request["PlacePK"].ToString();
string PlaceName = GridView1.Rows[Convert.ToInt32(e.CommandArgument)].Cells[1].Text.ToString();
string PlaceID = GridView1.Rows[Convert.ToInt32(e.CommandArgument)].Cells[2].Text.ToString();
new _PlacRCTableAdapters.PlaceTableAdapter().UpdatePlaceByKey(PlaceName, PlaceID, new Guid(PlacePK));
string sScript = "<script language=\"javascript\"> window.parent.close();</script>";
ClientScript.RegisterClientScriptBlock(GetType(), "Startup", sScript);
}

}

1.GridView1控件创建时的事件操作

如果是数据行
if (e.Row.RowType == DataControlRowType.DataRow)
获取页面传值
string PlacePK = Request["PlacePK"].ToString();
找到GridView1控件行中第下标为3列的控件ID为lBtnSelect
LinkButton linkbutton = (LinkButton)e.Row.Cells[3].FindControl("lBtnSelect");
给该控件设置命令
linkbutton.CommandArgument = e.Row.RowIndex.ToString();

2.GridView1有命令操作时

如果命令为select
if (e.CommandName == "select")
获取页面传值
string PlacePK = Request["PlacePK"].ToString();
获取命令行中第下标为1单元格的值
string PlaceName = GridView1.Rows[Convert.ToInt32(e.CommandArgument)].Cells[1].Text.ToString();
这句应该是对数据库的更新操作
new _PlacRCTableAdapters.PlaceTableAdapter().UpdatePlaceByKey(PlaceName, PlaceID, new Guid(PlacePK));
注册一段脚本
ClientScript.RegisterClientScriptBlock(GetType(), "Startup", sScript);
