推荐答案

为GridViewColumn.CellTemplate创建一个名为EditBox的自定义控件.

Create a customized control called EditBox for GridViewColumn.CellTemplate.

在正常模式下，TextBlock用于显示内容. 在编辑模式下，将弹出一个文本框进行编辑.

In Normal mode, a TextBlock is used to display content; In Editing mode, a TextBox will pop up for editing.

从Control继承的类

Class inhertied from Control

在ListView中编辑

public class EditBox : Control
{
            static EditBox()
            {              
            public static readonly DependencyProperty ValueProperty =
                    DependencyProperty.Register(
                            "Value",
                            typeof(object),
                            typeof(EditBox),
                            new FrameworkPropertyMetadata());
}

为IsEditing添加依赖项属性.

Add a dependency Property for IsEditing.

 public static DependencyProperty IsEditingProperty =
                    DependencyProperty.Register(
                            "IsEditing",
                            typeof(bool),
                            typeof(EditBox),
                            new FrameworkPropertyMetadata(false)
                            );

自定义EditBox的样式:

Style for the Custom EditBox:

 <Style x:Key="{x:Type l:EditBox}" TargetType="{x:Type l:EditBox}" >
      <Setter Property="HorizontalAlignment" Value="Left"  />
      <Setter Property="Template">
        <Setter.Value>
          <ControlTemplate TargetType="{x:Type l:EditBox}">
                <TextBlock x:Name="PART_TextBlockPart" 
                     Text="{Binding Path=Value, RelativeSource = {RelativeSource TemplatedParent}}">
                </TextBlock>
          </ControlTemplate>
        </Setter.Value>
      </Setter>
    </Style>

在您的Xaml中，您可以放置​​EditBox:

In your Xaml, you can place the EditBox:

   <GridViewColumn Header="Description" >
        <GridViewColumn.CellTemplate>
            <DataTemplate>
               <i:EditBox>
            </DataTemplate>
        </GridViewColumn.CellTemplate>
    </GridViewColumn>
