试图找出如何取消TabControl.SelectionChanged在Silverlight [英] Trying find how to cancel TabControl.SelectionChanged in silverlight

问题描述

我想弄清楚如何在Silverlight取消本次活动，遗憾的是我没有找到解决任何有用的链接:(（我看到一些职位WPF至极，我认为不能再使用Silverlight的）

I am trying figure out how cancel this event in silverlight, sadly i didn't find any useful link with the solution :( (i saw some post for wpf wich i think are not longer available for silverlight)

推荐答案

下面是它的基本框架： -

Here is the bare bones of it:-

    bool cancellingTabSelectionChange = false;
    private void tabControl1_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        if (e.RemovedItems.Count > 0 && !cancellingTabSelectionChange)
        {
            cancellingTabSelectionChange = true;
            ((TabControl)sender).SelectedItem = e.RemovedItems[0];
            cancellingTabSelectionChange = false;
        }
    }

您将需要添加额外的标准，将允许改变发生的，因为上面的code总是阻止标签的变化。

You would need to add the extra criteria the would allow a change to take place since the above code would always block a change of tab.
