如何测试在VB.net TabControl中选择哪个选项卡

Question

我有一个带有两个TabPages的TabControl,我想知道测试当前显示哪个选项卡的最佳方法是什么？我不知道为什么我不能想出这一个......

Answer 1

TabControl.SelectedTab

Answer 2

使用该标签的"输入事件",例如.

   Private Sub TabName_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TabName.Enter
        MsgBox("me the tab selected")
         'or do whattever u like
    End Sub

Answer 3

Private Sub TabControl_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabControl.SelectedIndexChanged
    If TabControl.SelectedTab Is tabMyTab Then
        ' do whatever...
    End If
End Sub
