Hi Guys,

Just having an issue that has completely stumped me.

In a nutshell, how to hide/show certain controls when a tabpage is changed?
ie. when the tabpage 1 is switched to tabpage 2 by the users, I want to hide the menustrip and toolbar.

Cheers

推荐答案

TabControl对象具有一个称为Selected的事件.
选择新选项卡后，将触发此事件.事件参数中包含的对象之一是刚刚选择的TabPage.

因此，在该方法中，您可以检查e.TabPage.Name并查看是否要显示或隐藏控件.

The TabControl object has an event called Selected.

When a new tab is selected, this event fires. One of the objects included in the event''s arguments is the TabPage that was just selected.

So, in the method, you can check e.TabPage.Name and see if you want to show or hide the controls.

我使用TabControl的SelectedIndexChanged事件.确保您正在查看 TabControl 而不是 TabPage 的事件.您可以包含如下代码来检查选择了哪个TabPage:

I use the TabControl''s SelectedIndexChanged Event. Make sure you are looking at events for the TabControl not the TabPage. You can include code that checks which TabPage is selected like this:

Private Sub tcMyTabControl_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles tcMyTabControl.SelectedIndexChanged
       'If newly selected tab is tabpage2
       If tcMyTabControl.SelectedTab Is tpTabPage2 Then
          'Hide menu/toolbar
       Else
          'Show menu/toolbar           
       End If
End Sub

希望这会有所帮助.

Hope this helps.
