Silverlight的tabchanged事件 - 的tabcontrol [英] Silverlight tabchanged event - tabcontrol

问题描述

我使用标签控件，我想处理tabchanged事件。

I'm using tab control and I want to handle tabchanged event.

我试图用的SelectionChanged 事件没有运气。它被解雇次数太多（装载的TabControl，或添加新标签后）。
我想处理此事件，只有当用户选项卡之间进行导航。

I was trying to use SelectionChanged event with no luck. It's being fired too many times (after loading tabcontrol, or adding new tab). I would like to handle this event only when user navigates between tabs.

我已经找到解决方案，WPF（的是否有选定的选项卡更改事件标准WPF Tab控件），但它没有良好的Silverlight的。
TIA。

I have found solution for WPF (Is there Selected Tab Changed Event in the standard WPF Tab Control) but it's no good for Silverlight. TIA.

推荐答案

射击太多次：如果你检查的实际变化不应该是一个问题在的SelectedIndex 属性在事件。

Firing "too many times" should not be a problem if you check for an actual change to the SelectedIndex property in the event.

private int LastSelectedTab = -1;

void tab_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    TabControl tab = sender as TabControl;
    if (this.LastSelectedTab != tab.SelectedIndex)
    {
        this.LastSelectedTab = tab.SelectedIndex;
        // Now do your thing...
    }
}
