动态绑定DATAGRID里的DropDownList

if(e.Item.ItemType==ListItemType.EditItem)

{

DataRowView drv=(DataRowView)e.Item.DataItem;

string currentValue=drv["CUR_ID"].ToString();

DropDownList ddl=(DropDownList)e.Item.FindControl("ddl_CurInfo");

DataTable table=ReadCurInfo();

ddl.DataSource=table;

ddl.DataTextField="CUR_CHNAME";

ddl.DataValueField="CUR_ID";

ddl.DataBind();

ddl.Items.Insert(0,new ListItem("请选择",""));

ddl.SelectedIndex=ddl.Items.IndexOf(ddl.Items.FindByValue(currentValue));

}

if(e.Item.ItemType==ListItemType.AlternatingItem||e.Item.ItemType==ListItemType.Item)

{

HyperLink hpl=(HyperLink)e.Item.FindControl("hpy_Attch");

DataRowView drv=(DataRowView)e.Item.DataItem;

string fileAttch=drv["OWNMANA_APPENDFILE"].ToString();

hpl.NavigateUrl=fileAttch;

hpl.Text=fileAttch.Substring(fileAttch.LastIndexOf(@"\")+1);

}
