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>
