我試圖將列表框綁定到列表框的內容。出於某種原因，我得到了bluetape列表的結果，但BluetapeList的內容並沒有進入列表框。任何幫助將非常感激！將列表框綁定到列表<string>
XAML：
<ListBox
Name="lbxTapeIn"
Grid.Row="1"
Grid.Column="1"
Grid.ColumnSpan="1"
Width="70"
Height="80"
SelectionChanged="TapeSelectionChanged"
ItemsSource="{Binding}"
SelectedValue="{Binding SelectedBt}"
Background="DeepSkyBlue"
Foreground="MidnightBlue"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Margin="5"/>
代碼背後：
public partial class OverrideAoiBinningWindow : Window
{
private OverrideAoiBinningWindowViewModel ovAoiBinWin;
public OverrideAoiBinningWindow()
{
InitializeComponent();
ovAoiBinWin = new OverrideAoiBinningWindowViewModel(tvwWaferList, txtFilter);
AssignDataContexts();
}
private void AssignDataContexts()
{
btnChooseWafer.DataContext = ovAoiBinWin;
btnSave.DataContext = ovAoiBinWin;
txtWafer.DataContext = ovAoiBinWin;
cbxAoiState.DataContext = ovAoiBinWin;
lbxTapeIn.DataContext = ovAoiBinWin.BluetapeList;
}
private void TapeSelectionChanged(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrEmpty(ovAoiBinWin.SelectedWafer))
{
if (cbxAoiState.SelectedValue != null)
{
btnSave.IsEnabled = true;
}
}
}
private void AoiStateChanged(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrEmpty(ovAoiBinWin.SelectedWafer))
{
if (lbxTapeIn.SelectedValue != null)
{
btnSave.IsEnabled = true;
}
}
}
private void Close(object sender, RoutedEventArgs e)
{
this.Close();
}
}

建議：使用'DataBind（）'方法（如果存在）。 – gunr2171 2013-05-08 17:06:45
在您的XAML上設置ItemsSource =「{Binding Path = BluetapeList}」SelectedValue =「{Binding Path = SelectedBt}」並將DataContext設置爲此。 lbxTapeIn.DataContext = this;注：綁定後將項目添加到列表將不會顯示在ListBox中。可能是你應該嘗試ObservableCollection。 – Dilshod 2013-05-08 17:09:49
