我的html看起来像这样:
<select data-bind="options: movieInitValues,
optionsText: 'Text',
optionsValue: 'Value',
value: movieSelectedValue,
visible: movieSelectVisible"></select>
<input data-bind="autoMovieComplete: {
selected: movieSelectedValue,
selectedName: movieSelectedName},
visible: showMovieDD,
disable: promoCodeInvalid" id="MovieName" type="text" />
基本上,我的想法是在某些参数下我会显示一个带有自动完成功能的文本框,在其他情况下我会显示下拉列表。可见&#39;绑定允许我做隐藏,但绑定怎么样。我只希望其中一个绑定到movieSelectedValue,我该如何以编程方式执行此操作?

public MainWindow()
{
// At design time (in your XAML), initialize to the "Loading..." state
InitializeComponent()
}
private async void Window_Loaded(object sender, RoutedEventArgs e)
{
ClassA hello = new ClassA();
await hello.ConnectAsync();
//List will be used as Source for DataGrid
List<object> DataGridViewSource List<object>();
//use the instance of hello to get some Data from the WebService.
List<int> objectIds = new List<int>();
objectIds = hello.GetObjectIds("LDAPQuery");
foreach (int id in objectIds)
{
var tmpObj = await hello.GetObjectByIdAsync(id);
DataGridViewSource.Add(tmpObj);
}
//do binding to DataGrid
}
binding可行。除非条件的计算结果为true,否则它会阻止任何内部渲染。如果您不想将这些人包装在if
中,可以将它与无容器语法结合使用。
它还负责可见性方面,因为它完全从DOM中删除它。
