[ASP.net教程]使用DataSource绑定一维数组时,DataTextField只需绑定空字符串

方法定义:

 1 public static void InitDropDownList(DropDownList ddl, bool isAddTopItem, DropDownList ddlSub, object ddlDataSource, string ddlTextField, string ddlValueField) 2 { 3   ddl.DataSource = ddlDataSource; 4   ddl.DataTextField = ddlTextField; 5   ddl.DataValueField = ddlValueField; 6   ddl.DataBind(); 7   if (isAddTopItem) 8     ddl.Items.Insert(0, new ListItem("--All--", "0")); 9   if (ddlSub != null)10     ddlSub.Items.Insert(0, new ListItem("--All--", "0"));11 }

 

使用方式:

1 XXClass.InitDropDownList(ddlAvailableFieldEnter, false, null, new string[]{"field1","field2","field3"}, "", "");
