将多个数据项从SQL绑定到标签

Question

如何将多个数据项从SQL绑定到标签？

这是我的代码：

Dim str As String = ("Data Source=PC1; User ID=sa; Password=pwd;Databasfriend") 
    Dim con As New SqlConnection(str) 
    Dim str1 As String = "SELECT * FROM tbl_course" 
    Dim da As New SqlDataAdapter(str1, con) 
    Dim dataset1 As New DataSet() 
    da.Fill(dataset1, "course") 
    lbl.DataBindings.Add("text", dataset1, "course.Course_Code") 

它只是绑定一个数据的项目，我想绑定在一个特定的列数据的许多项目

您可以创建在SQL语句的字符串和绑定到：

Dim str1 As String = "SELECT Course_Title + '(' + Course_Code + ')' AS lbl1 FROM tbl_course" 

..

lbl.DataBindings.Add("text", dataset1, "course.lbl1")
