Create a customized control called EditBox for GridViewColumn.CellTemplate.
为 GridViewColumn.CellTemplate 创建一个名为 EditBox 的自定义控件。
In Normal mode, a TextBlock is used to display content; In Editing mode, a TextBox will pop up for editing.
在 Normal 模式下，TextBlock 用于显示内容；在编辑模式下，会弹出一个文本框进行编辑。
Class inhertied from Control
继承自 Control 的类
public class EditBox : Control
{
static EditBox()
{
public static readonly DependencyProperty ValueProperty =
DependencyProperty.Register(
"Value",
typeof(object),
typeof(EditBox),
new FrameworkPropertyMetadata());
}
Add a dependency Property for IsEditing.
为 IsEditing 添加依赖属性。
public static DependencyProperty IsEditingProperty =
DependencyProperty.Register(
"IsEditing",
typeof(bool),
typeof(EditBox),
new FrameworkPropertyMetadata(false)
);
Style for the Custom EditBox:
自定义编辑框的样式：
<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>
In your Xaml, you can place the EditBox:
在您的 Xaml 中，您可以放置 EditBox：
<GridViewColumn Header="Description" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<i:EditBox>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
