我看button控件是单个的.我能做个类似组合的GROUPBUTTON控件吗?

这个是重写的button

[Forrest23]

那你就动态创建button控件吧 想建几个就几个~

[lanlan85525]

自定义控件。。。

[bigeyescat]

是不是想做个像VB6的按钮组?那你就做个自定义组件,拉个空器,代码动态创建按钮,写属性、事件。。。
做好在表单上拖放

[Forrest23]

动态创建控件数组，建立事件

Dim PanelButtons As New Panel
PanelButtons.Dock = DockStyle.Fill

For i As Integer = 0 To 99
Dim btn As New Button
btn.Text = "Student" & (i + 1).ToString()
btn.Tag = "ID_" & i.ToString
btn.Location = New Point((i Mod 10) * btn.Width, (i \ 10) * btn.Height)
AddHandler btn.Click, AddressOf btn_click
PanelButtons.Controls.Add(btn)
Next

Me.Controls.Add(PanelButtons)

'事件
Private Sub btn_click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim btn As Button
btn = CType(sender, Button)
MsgBox(String.Format("You click Button # {0}", btn.Tag))
End Sub

当然可以了，你可以自定义用户控件，一个个把button托进来，然后用EventHandler声明事件的句柄，在要触发的时候，用Raise ...触发就可以了。
