遇到问题,控件ListItem和DropDownList绑定数据库数据后selectedindex数 > 值始终为-1,导致无法选定索引号。 > 考虑解决办法:不直接绑定,数据库数据连接到ArrayList后再用控件的 > Items.Add方法添加内容 Dim myConn As SqlConnection = New SqlConnection("Server=localhost;" & _ "Database=Pubs;UID=sa;PWD=") Dim myCmd As SqlCommand = New SqlCommand("SELECT au_id," & _ "au_lname FROM Authors", myConn)
myConn.Open() Dim myReader As SqlDataReader = myCmd.ExecuteReader()
'Set up the data binding. AuthorList.DataSource = myReader AuthorList.DataTextField = "au_lname" AuthorList.DataValueField = "au_id" AuthorList.DataBind()
'Close the connection. myConn.Close() myReader.Close()
'Add the item at the first position. AuthorList.Items.Insert(0, "<-- Select -->")
