使用文本框或复选框取决于一个attribue的类型 [英] using textbox or checkbox depending on the type of an attribue
问题描述
如果我有这样的结构:
public class Parent
{
public string Name{get; set;}
public List<Child> Childs {get; set;}
}
public class Child
{
public string Name{get; set;}
public int Age {get; set;}
public bool Married {get; set;}
}
public class ParentFactory
{
public List<Parent> Parents {get; set;}
public ParentFactory()
{
Child child1 = new Child() {Name="Peter", Age=10, Married=true};
Child child2 = new Child() {Name="Mary", Age=9, Married=false};
Child child3 = new Child() {Name="Becky", Age=12, Married=true};
Parent parent1 = new Parent(){Name="Adam", Childs = new List<Child>(){child1, child2}};
Parent parent2 = new Parent(){Name="Kevin", Childs = new List<Child>(){child3}};
Parents = new List<Parent>(){parent1, parent2};
}
}
我要的对象绑定:ParentFactory parentFactory =新ParentFactory();到ItemsControl的:
I want to bind the object: ParentFactory parentFactory = new ParentFactory(); to ItemsControl:
<DockPanel>
<ItemsControl ItemsSource="{Binding Parents}">
</ItemsControl>
</DockPanel>
<Window.Resources>
<DataTemplate DataType="{x:Type Parent}">
<StackPanel Margin="2,2,2,1">
<Expander Header="{Binding Name}">
<ItemsControl ItemsSource="{Binding Childs}" />
</Expander>
</StackPanel>
</DataTemplate>
<DataTemplate DataType="{x:Type Child}">
<StackPanel>
<TextBox Grid.Column="0" Text="{Binding Name}" />
<TextBox Grid.Column="1" Text="{Binding Age}"/>
<CheckBox Grid.Column="2" IsChecked="{Binding Married}"/>
</StackPanel>
</DataTemplate>
</Window.Resources>
在的StackPanel,有两种类型的控制:文本框和CheckBox。不过,我想他们更动态的:如果该值是一个布尔然后使用复选框,并可以使用一个文本框。这意味着我不需要定义控制或者文本框或StackPanel的内部复选框由于我的孩子一类众多的属性。可能吗?如果是,我怎么能实现这些目标。请您提供一些代码示例?
In the Stackpanel, there are two types of controls: TextBox and CheckBox. However, I want them to be more dynamic: if the value is a boolean then use a Checkbox and else use a Textbox. That means I dont need to define the control either TextBox or Checkbox inside the StackPanel due to a numerous attributes in my Child class. Would it be possible? and if yes, how can I achieve them. could you please provide some code samples?
在此先感谢。
推荐答案
我已经做了从我从你的问题理解的解决方案。请看看吧。
样品是基于DataTrigger,你可以改变的逻辑,以转换
I have done a solution from what i understood from your question. Please have a look at it. The sample is based on the DataTrigger and you can change the logics to Converter.
