我该如何进行数据绑定? [英] How Do I do databinding?

问题描述

大家好，

我需要有关如何解决以下情况的建议:

我有三个用户控件:
- FileInfoView
-> SummaryView
-> PersonalInfoView

我使用了另一个userControl在FileOpenView中将它们分组在一起:

< UserControl.... FileInfoView>
.................
</UserControl>


#region附加属性)
{
返回(TreatmentSession)obj.GetValue(TreatmentSessionProperty); (TreatmentSessionProperty，value);
}

////使用DependencyProperty作为TreatmentSessionProperty的后备存储.这将启用动画，样式，绑定等.在这个问题中，我还使用了MwiChild(来自http://www.codeproject.com/KB/WPF/mwiwpf.aspx).目前，我在FileOpenView中具有附加的依赖项属性. .


FileInfoView具有BackgroundWorker对象，FileOpenController将使用该对象读取保存的文件.它处理worker_ProgressCompleted事件.我如何从这里更新dependencyProperties?最重要的是，我使用的是正确的方法吗?

请提出建议. :D

谢谢..

Hi All,

        I need a suggestion on how do I solve the following scenario:

I have three user Controls:
   -> FileInfoView
   -> SummaryView
   -> PersonalInfoView

I used another userControl to group them together in FileOpenView:
  
    <UserControl .... >
            <TabItem header=>
                   <local:FileInfoView>
.................
   </UserControl>

        #region Attached Properties
        public static TreatmentSession GetTreatmentSessionProperty(DependencyObject obj)
        {
            return (TreatmentSession)obj.GetValue(TreatmentSessionProperty);
        }

        public static void SetTreatmentSessionProperty(DependencyObject obj,Treatmentession value)
        {
            obj.SetValue(TreatmentSessionProperty, value);
        }

        // Using a DependencyProperty as the backing store for TreatmentSessionProperty.  This enables animation, styling, binding, etc...
        public static readonly DependencyProperty TreatmentSessionProperty =
            DependencyProperty.RegisterAttached("TreatmentSessionProperty", typeof(ABPMSession), typeof(OpenFileView));
        #endregion


In this problem, I also used a MwiChild (from http://www.codeproject.com/KB/WPF/mwiwpf.aspx)
Currently I have an attached dependency properties in the FileOpenView.


FileInfoView have a BackgroundWorker object,which will be used by a FileOpenController to read a saved file. and it handles the worker_ProgressCompleted event. How do I update the dependencyProperties from here? and most importantly, am I using the correct method?

Please advice. :D

Thanks..
