点击到编辑在Silverlight [英] Click-to-edit in Silverlight

问题描述

有没有一种方法，使Silverlight中的一个点击编辑的控制？我有一些项目是
将显示在一个TreeView控件，我想的标签可编辑直接在树视图。

Is there a way to make a "click-to-edit" control in silverlight? I've got some items that will be displayed in a treeview control, and I would like the labels to be editable directly in the treeview.

任何人都知道如何做到这一点？

Anyone know how to do this?

推荐答案

很容易实际。我已经实现了这样的交换机制多种形式。

Very easy actually. I have implemented many forms with such a swapping mechanism.

您可以做到这一点使用一个转换器和做对即在实体上存在的IsEditable产权简单BooleanToVisibility转换你绑定到你的TreeView。在您的TreeView的ItemTemplate只是绑定文本块以这样一种方式，它是折叠每当IsEditable属性为true，并绑定文本框以这样的方式，它是collapesed当IsEditable属性为false（反之亦然）。

You could do this using a Converter and do a simple BooleanToVisibility conversion on an IsEditable property that exists on the entities that you bind to your TreeView. Within your TreeView ItemTemplate just bind the TextBlock in such a way that it is Collapsed whenever the IsEditable property is true and bind the TextBox in such a way that it is collapesed when IsEditable property is false (and vice versa).

如果你想建立你需要做以下的自定义ClickToEdit控制：

If you wanted to build a custom ClickToEdit control you would need to do the following:

1. 创建即自ContentControl继承的类


2. 揭露类型DataTemplate中的一个新的依赖属性：一个叫EditableTemplate


3. 您OnApplyTemplate里面添加的MouseLeftButtonUp事件处理程序监听点击。


4. 更改活动内容模板成为您的单击事件EditableTemplate。


5. 更改模板回当控件失去焦点

1. Create a class that inherits from ContentControl
2. Expose a new dependency properties of type DataTemplate: one called EditableTemplate.
3. Add a MouseLeftButtonUp event handler inside your OnApplyTemplate to listen for the click.
4. Change the active content template to be your EditableTemplate on the click event.
5. Change the template back when the control loses focus.

现在使用里面的TreeView自定义控件：

Now to use your custom control inside TreeView:

1. 覆盖您的ItemTemplate为您的TreeView


2. 把你的自定义ClickToEdit控制里边有

实现自定义控制将允许你（或其他开发者）可以轻松地指定他们想要的内容编辑器使用什么样的控制。例如，他们可以指定一个或的NumericUpDown一个DateTimePicker，而不是只使用一个文本框的。

Implementing a custom control would allow you (or other developers) to easily specify what control they wanted to use as the content editor. For example, they could specify a NumericUpDown or a DateTimePicker instead of just using a TextBox.

检查出来的DataForm在Silverlight 3，具有类似的功能，但可编辑的开关与只读不被点击进行。

Check out DataForm in Silverlight 3. It has similar functionality but the switching of the editable vs. read-only is not done by a click.
