Question

我能想到的唯一例子是html - 如果你动态添加一个TR w /一个colspan + div，其中包含详细信息（可编辑），例如点击前一个TR

我正试图捣乱XAML，并希望看看是否有人能指出我这个古怪的要求正确的方向。

Answer 1

这是一些东西，不确定它是否是你要找的东西：

XAML：

<Grid Name="_mainGrid">
    <Grid.ColumnDefinitions>
        <!-- Contains the button -->
        <ColumnDefinition Width="Auto"/>
        <!-- Contains the edit control -->
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <!-- So that we have the 'empty' space at the end -->
        <RowDefinition Height="*"/> 
    </Grid.RowDefinitions>
</Grid>

代码：

    public Window1()
    {
        InitializeComponent();
        CreateRow(); // Bootstrap
    }

    private void CreateRow()
    {
        RowDefinition newRow = new RowDefinition();
        newRow.Height = new GridLength(0, GridUnitType.Auto);
        _mainGrid.RowDefinitions.Insert(_mainGrid.RowDefinitions.Count - 1, newRow);

        int rowIndex = _mainGrid.RowDefinitions.Count - 2;

        UIElement editControl = CreateEditControl();
        Grid.SetRow(editControl, rowIndex);
        Grid.SetColumn(editControl, 1);
        Grid.SetRowSpan(editControl, 1);
        Grid.SetColumnSpan(editControl, 1); // Change this if you want.
        _mainGrid.Children.Add(editControl);

        Button addButton = new Button();
        addButton.Content = "Add";
        addButton.Click += new RoutedEventHandler(b_Click);
        Grid.SetRow(addButton, rowIndex);
        Grid.SetColumn(addButton, 0);
        _mainGrid.Children.Add(addButton);
        addButton.Tag = editControl;

    }

    void b_Click(object sender, RoutedEventArgs e)
    {
        CreateRow();
        Control button = (Control)sender;
        UIElement editControl = (UIElement)button.Tag;
        _mainGrid.Children.Remove(button);
        Grid.SetColumn(editControl, 0);
        Grid.SetColumnSpan(editControl, 2);
    }

    private UIElement CreateEditControl()
    {
        return new TextBox();
    }

如何在WPF中动态添加详细信息行？
