在VB中,ListBox控件用于显示一个列表,用户可以选择其中的一个或多个项。以下是ListBox控件的使用步骤:
Dim listBox As New ListBox
Me.Controls.Add(listBox)
listBox.Items.Add("Item 1")
listBox.Items.AddRange({"Item 2", "Item 3", "Item 4"})
listBox.DataSource = dataSource
listBox.DisplayMember = "PropertyName"
listBox.SelectionMode = SelectionMode.Single
For Each selectedItem As Object In listBox.SelectedItems
' 处理选中项
Next
listBox.DrawMode = DrawMode.OwnerDrawFixed
Private Sub listBox_DrawItem(sender As Object, e As DrawItemEventArgs) Handles listBox.DrawItem
' 绘制项的内容
End Sub
这些是ListBox控件的基本用法。你可以根据实际需求进行进一步的自定义和操作。
