Question

我有一个wpf应用程序，我希望能够从网格中删除一个列，然后让其他列自己重新定位（即如果用户删除第一列，则所有其他列向左移动一个，如果用户通过单击按钮，在第二个列向左移动后删除第二列所有其他列。目前我只能隐藏列中的项目，它留下了我不想要的空白区域。

private void SetColumnWidthCol1()
    {
        Col2.Width = new GridLength(150);
        Col3.Width = new GridLength(150);

Answer 1

而不是Visibility.Hidden使他们成为Visibility.Collapsed。

喜欢 -

private void CloseContacts_Click(object sender, RoutedEventArgs e)
{
    ContactsLabel.Visibility = System.Windows.Visibility.Collapsed;
    CloseContacts.Visibility = System.Windows.Visibility.Collapsed;
}
