How do I programmatically select a tab on a .NET CF TabControl?
提问by raven
With the .NET Framework 2.0/3.5 TabControl, I can programmatically select a tab using the SelectedTab property as shown in the code below:
使用 .NET Framework 2.0/3.5 TabControl，我可以使用 SelectedTab 属性以编程方式选择一个选项卡，如下面的代码所示：
//toggles between tabPage1 and tabPage2
private void button1_Click(object sender, EventArgs e)
{
if (tabControl1.SelectedTab == tabPage1)
tabControl1.SelectedTab = tabPage2;
else
tabControl1.SelectedTab = tabPage1;
}
The .NET CompactFramework TabControl doesn't have a SelectedTab property like its .NET Framework counterpart. So, how do I select a tab programmatically?
.NET CompactFramework TabControl 不像它的 .NET Framework 对应物那样有 SelectedTab 属性。那么，如何以编程方式选择选项卡？

I programmed this code. When click on tabPage1, then the program will close:
我编写了这段代码。当点击tabPage1时，程序将关闭：
private void tabControl1_MouseClick(object sender, MouseEventArgs e)
{
if (tabControl1.SelectedTab == tabPage1)
{
MessageBox.Show("Logout!");
Application.Exit();
}
}

I found that when the TabControl is selected, it does not display correctly. It seems that after selecting a TabControl it is useful to Refresh it. So, where the TabControl is called TabForm and has multiple Tabs, this might be:
我发现选择TabControl时，显示不正确。似乎在选择 TabControl 后刷新它很有用。因此，在 TabControl 称为 TabForm 并具有多个选项卡的情况下，这可能是：
Me.TabForm.SelectedIndex = 0
Me.TabPg0.Refresh 'Where TabPg0 is the name of the Tab at Index 0
