c# - DataTemplateColumn 需要 2 个选项卡才能获取内容

Question

我找了很多关于这个问题的文章，但是好像都没有用。我有 3 个 DataTemplateColumns，两个带有文本框，一个带有切换按钮。首先通过 Tab 键转到单元格，然后是内容。我尝试了很多来自其他网站的建议和我自己的发明，但都没有成功。我可以让它在第一行工作，当我添加另一个时，但一次添加 2 个，它就会停止工作。我恨。数据模板。列。这是我当前使用的类，利用依赖属性。

public class FocusAttacher
{
    public static readonly DependencyProperty FocusProperty = 
        DependencyProperty.RegisterAttached("Focus", 
        typeof(bool), 
        typeof(FocusAttacher), 
        new PropertyMetadata(false, FocusChanged));

    public static bool GetFocus(DependencyObject d)
    {
        return (bool)d.GetValue(FocusProperty);
    }

    public static void SetFocus(DependencyObject d, bool value)
    {
        d.SetValue(FocusProperty, value);
    }

    public static void FocusChanged(object sender, DependencyPropertyChangedEventArgs e)
    {
        if ((bool)e.NewValue)
        {
            ((UIElement)sender).Focus();
        }
    }

<DataGridTemplateColumn Header="Some Value"
                                    MinWidth="30"
                                    Width=".02*">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <TextBox Text="{Binding SomeBinding, 
                                                ValidatesOnDataErrors=True, 
                                                UpdateSourceTrigger=PropertyChanged}"
                                 IsReadOnly="{Binding RelativeSource={RelativeSource FindAncestor, 
                                               AncestorType={x:Type DataGrid}}, 
                                               Path=DataContext.IsReadOnly}"
                                 Style="{StaticResource SomeStyle}"
                                 customControls:FocusAttacher.Focus="True"/>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>

奇怪的是，这仅适用于文本框，而不适用于我第三列中的切换按钮。啊!!!!!!

编辑:这是按钮的数据模板。它被设置为严格用于样式和触发器目的的自定义控件。它是一个带有包含边框和内容呈现器的控件模板的按钮。

<DataTemplate>
    <customControls:MetroButton cal:Message.Attach="[Event Click] = [Action RemoveGroup($dataContext)]"
           Width="15"
           Height="15"
           IsTabStop="False"
           Focusable="False"
           MouseOverBackground="LightGray">
           <Button.Visibility>
           <MultiBinding Converter="{StaticResource BoolsToVisibilityAndConverter}">
                                    <Binding Path="IsReadOnly"
                                                 Converter="{StaticResource BooleanInverterConverter}" 
                                                 RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}"/>
                                    <Binding Path="IsDeletable"/>
                                </MultiBinding>
                            </Button.Visibility>
                            <TextBlock Text="-"
                                       Focusable="False"
                                       Margin="0 -6 0 0" />

                        </customControls:MetroButton>
                        </DataTemplate>

编辑:添加按钮自定义控件。

在我开枪之前请帮助我。谢谢

对我来说这行得通:

<DataGrid.CellStyle>
    <Style TargetType="{x:Type DataGridCell}">
        <Setter Property="IsTabStop" Value="False" />
        <Setter Property="Focusable" Value="False" />
    </Style>
</DataGrid.CellStyle>
