摘要：
我们经常使用与数据和前台控件绑定相关的问题。我们总是知道我们需要使用委托（代理），但我们每次都会忘记它。每次我们一次又一次地使用百度时，我们的记忆都不长。这一次，我们必须认真地写下来，下次我们不会忘记它。后台数据和前台数据的绑定主要分为两个步骤：第一步是将要绑定的数据定义为数据集或对象，并将其绑定到List以便于调用：publicclassTestCase:INotifyPropertyChanged｛publiceventPro
经常会用到数据与前台控件绑定相关的问题，一直知道要用委托（代理）但每次都忘，而且每次都百度了一遍又一遍，就是不长记性，这次一定好好记下来下次就不会忘了。
后台数据与前台绑定主要分为两步：
第一步把要绑定的数据定义为一个数据集合或对象绑定到List中，方便调用：
public class TestCase:INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; private string caseID; private string commFile; private string commParameter; private string commFlag; private string startTime; private string endTime; private string executionTime; private string executionResult; public string CaseID { get { return caseID; } set { caseID = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("CaseID")); } } public string CommFile { get { return commFile; } set { commFile = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("CommFile")); } } public string CommParameter { get { return commParameter; } set { commParameter = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("CaseID")); } } public string CommFlag { get { return commFlag; } set { commFlag = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("CommFlag")); } } public string StartTime { get { return startTime; } set { startTime = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("StartTime")); } } public string EndTime { get { return endTime; } set { endTime = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("EndTime")); } } public string ExecutionTime { get { return executionTime; } set { executionTime = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("ExecutionTime")); } } public string ExecutionResult { get { return executionResult; } set { executionResult = value; if (this.PropertyChanged != null) this.PropertyChanged.Invoke(this, new PropertyChangedEventArgs("ExecutionResult")); } } }
对象创建好了就可以第二步实现数据一条一条更新了：
/// <summary> /// Set Listview Value /// </summary> /// <param name="lv"></param> /// <param name="obj"></param> public static void UpdateListViewValue(ListView lv, Object obj) { lv.Dispatcher.Invoke( new Action( delegate { lv.Items.Add(obj); lv.ScrollIntoView(obj); } )); } /// <summary> /// Set ProgressBar Value /// </summary> /// <param name="pb"></param> /// <param name="value"></param> public static void UpdateProgressBarValue(ProgressBar pb, double value) { pb.Dispatcher.Invoke( new Action( delegate { pb.Visibility = Visibility.Visible; } )); pb.Dispatcher.Invoke(new Action<System.Windows.DependencyProperty, object> (pb.SetValue), System.Windows.Threading.DispatcherPriority.Background, System.Windows.Controls.ProgressBar.ValueProperty, value ); } /// <summary> /// Set Label Value /// </summary> /// <param name="lb"></param> /// <param name="value"></param> public static void UpdateLableValue(Label lb, string value) { lb.Dispatcher.Invoke( new Action( delegate { lb.Visibility = Visibility.Visible; lb.Content = value; } )); }
这下好了，记下来就不怕忘了。
