Xaml中的WPF单选按钮组
在我们正在构建的WPF应用程序中,我们在各个堆叠面板中并排放置了3组单选按钮。我们正在尝试编程以下行为。当在表单中进行tab时,我们不希望在每个radiobutton的标准行为中进行tab,而是希望在每个组中的第一个radiobutton上进行tab,并能够在tab到该组后向上/向下箭头指向每个组中的其他radiobutton列表。我们已经为列表中第一个单选按钮下面的单选按钮设置了IsTabStop=False。这为我们提供了在每个组中进行选项卡切换所需的行为,但这不允许向上/向下箭头显示列表。只有当IsTabStop=True时,上/下箭头行为才起作用。我们还尝试设置radiobutton的GroupName属性,但其行为与上述相同。在旧的win表单中,有一个单选按钮列表控件具有这种行为,我们正在尝试重新创建它。有人知道如何重现这种行为吗?提前感谢你的帮助 若要从左向右更改方向,请将FlowDirection属性设置为RightToLeft RadioButton用于组中,因此用户只能从可用选项中选择一个选项,无需额外编码即可取消选中其他选项。使用相同的单选按钮组名在组中进行标记,以便只能选择一个选项,如下所示Xaml中的WPF单选按钮组,xaml,radiobuttonlist,Xaml,Radiobuttonlist,在我们正在构建的WPF应用程序中,我们在各个堆叠面板中并排放置了3组单选按钮。我们正在尝试编程以下行为。当在表单中进行tab时,我们不希望在每个radiobutton的标准行为中进行tab,而是希望在每个组中的第一个radiobutton上进行tab,并能够在tab到该组后向上/向下箭头指向每个组中的其他radiobutton列表。我们已经为列表中第一个单选按钮下面的单选按钮设置了IsTabStop=False。这为我们提供了在每个组中进行选项卡切换所需的行为,但这不允许向上/向下箭头显示列表。

我认为键盘导航附加的属性会起作用 我在XAML中模拟了一个快速WPF示例,很抱歉长度太长,使用ItemsControl对RadioButton元素进行分组:

解决方案是使用将列表框样式设置为单选按钮组的技术。然后可以在样式化列表框之间进行制表,并使用箭头键选择单个“单选按钮”列表框项 这里有一个完整的演示,也可以作为 Xaml
你没有真正回答这个问题
public class RadioButtonGroupsViewModel
{
public RadioButtonGroupsViewModel()
{
Items1 = new List<string> {"One", "Two", "Three"};
Selected1 = "One";
Items2 = new List<string> {"Four", "Five", "Six"};
Selected2 = "Five";
Items3 = new List<string> {"Seven", "Eight", "Nine", "Ten"};
Selected3 = "Ten";
}
public IEnumerable<string> Items1 { get; private set; }
public string Selected1 { get; set; }
public IEnumerable<string> Items2 { get; private set; }
public string Selected2 { get; set; }
public IEnumerable<string> Items3 { get; private set; }
public string Selected3 { get; set; }
}
