我想我有一个非常简单的问题,但我似乎把这个想法复杂化了,也许有人可以指导我或帮助我。
我有一个列表框和文本框,我想将文本从列表框复制到文本框。
我在WPF中的代码如下:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="465" Width="681">
<Grid>
<ListBox x:Name="listbox1" HorizontalAlignment="Left" Height="405" Margin="10,10,0,0" VerticalAlignment="Top" Width="208" MouseDown="listbox1_MouseDown">
<ListBoxItem Content="Gordon"/>
<ListBoxItem Content="Nico"/>
</ListBox>
<TextBox x:Name="textbox1" HorizontalAlignment="Left" Height="405" Margin="289,10,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="364" SpellCheck.IsEnabled="True" Cursor="IBeam" AcceptsReturn="True" AllowDrop="True" DragEnter="textbox1_DragEnter"/>
</Grid>
</Window>
我在 C# 中的代码如下,这就是我卡住的地方:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void listbox1_MouseDown(object sender, MouseButtonEventArgs e)
{
DragDrop.DoDragDrop(listbox1, listbox1.SelectedItem.ToString(), DragDropEffects.Copy);
}
private void textbox1_DragEnter(object sender, DragEventArgs e)
{
e.Effects = DragDropEffects.Copy;
}
private void textbox1_PreviewDragOver(object sender, DragEventArgs e)
{
e.Handled = true;
}
}
}
提前致谢。
