如何取消代码隐藏中的 Accordion.SelectionChanged？

我正在使用 silverlight 工具包 Accordion 控件。

我想根据某种逻辑取消手风琴选择。

例如：

private void Accordion_SelectionChanged(object sender, SelectionChangedEventArgs e) {
    if(Something) {
        e.SelectedItem = -1; //or anything that cancels the accordion "expansion"
        return;
    }
}

此代码会导致对 Accordion_SelectionChanged 的无限次调用，即使第一个递归调用不会影响所选项目。

还有其他方法可以做到这一点吗？

I'm using the silverlight toolkit Accordion control.

I want to cancel an accordion selection based on some logic.

For example:

private void Accordion_SelectionChanged(object sender, SelectionChangedEventArgs e) {
    if(Something) {
        e.SelectedItem = -1; //or anything that cancels the accordion "expansion"
        return;
    }
}

This code results in infinity calls to Accordion_SelectionChanged, even though the first recursive call do not affect the selected item.

Any other way to do this?

您可以手动阻止递归调用，如下所示：

bool isCancellingSelection = false;

private void Accordion_SelectionChanged(object sender, SelectionChangedEventArgs e) {
    if (isCancellingSelection)
        return;

    if(Something) {
        isCancellingSelection = true;
        e.SelectedItem = -1; 
        isCancellingSelection = false;
    }
}

You can manually prevent the recursive calls as follow:

bool isCancellingSelection = false;

private void Accordion_SelectionChanged(object sender, SelectionChangedEventArgs e) {
    if (isCancellingSelection)
        return;

    if(Something) {
        isCancellingSelection = true;
        e.SelectedItem = -1; 
        isCancellingSelection = false;
    }
}
