ListView-仅以编程方式选择索引 [英] ListView - select index only programmatically

问题描述

我正在尝试实现列表框(或列表视图):

i am trying to implement listbox (or listview):

<ListView ItemsSource="{Binding Players}" SelectedIndex="{Binding SelectedIndex}">

我的问题是，我想将所选索引绑定到代码隐藏的属性中. 它仅在表单开始时起作用，但我需要禁用用户才能更改选择.选择素将仅通过编程方式更改.

My problem is, that i want to bind selected index to property in code-behind. It work only on form start, but i need to disable user to change selection. Selectin will be changed ONLY programmaticaly.

感谢所有建议或解决方案:)

Thanks for all advices or solutions :)

推荐答案

因此，可行的解决方案:

So, working solution:

private void playersList_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (sender.GetType() == typeof(ListView))
    {
        (sender as ListView).SelectedIndex = GameObserver.Instance.core.SelectedIndex;
        e.Handled = true;
    }
}

在XAML中:

<ListView ItemsSource="{Binding Players}" SelectedIndex="{Binding SelectedIndex}" SelectionChanged="playersList_SelectionChanged">

和有界属性:

private int selectedIndex = 1;
public int SelectedIndex
{
    get
    {
        return selectedIndex;
    }
}
