问题描述

我有一个显示文本框列表的 wpf 列表框.当我单击文本框时，列表框选择不会改变.我必须在 TextBox 旁边单击才能选择列表框项.是否需要为文本框设置一些属性以将点击事件转发到列表框?

I Have a wpf Listbox that display's a list of textboxes. When I click on the Textbox the Listbox selection does not change. I have to click next to the TextBox to select the listbox item. Is there some property I need to set for the Textbox to forward the click event to the Listbox?

推荐答案

我们使用以下样式设置一个 PreviewGotKeyboardFocus，它处理 TextBox 控件和 ComboBoxes 等的所有事件:

We use the following style to set a PreviewGotKeyboardFocus which handles all events of TextBox control and ComboBoxes and such:

    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="PreviewGotKeyboardFocus" Handler="SelectCurrentItem"/>
        </Style>
    </ListView.ItemContainerStyle>

然后我们选择后面代码中的行:

And then we select the row in code behind:

    protected void SelectCurrentItem(object sender, KeyboardFocusChangedEventArgs e)
    {
        ListViewItem item = (ListViewItem) sender;
        item.IsSelected = true;
    }
