问题描述
我创建了一个带有按钮的工具栏。
I have created a toolbar that has buttons.
其中的3个按钮是剪切复制并粘贴的。我设置了每个按钮的命令以剪切复制并粘贴到属性上,但是当我运行程序时,甚至都没有可单击的按钮。我猜他们是残疾人士吗?我正在尝试从文本框复制并粘贴到tabcontrol中的文本框。任何帮助表示赞赏。
Of the buttons 3 of them are cut copy and paste. I set the command of each of those buttons to cut copy and paste on the properties but when I go run the program none of the buttons are even clickable. Are they disabled I'm guessing? I'm trying to copy and paste from textbox to textbox in a tabcontrol. Any help is appreciated.
<Style TargetType="{x:Type Button}" x:Key="textBoxCommands">
<Setter Property="Content"
Value="{Binding RelativeSource={RelativeSource Self},
Path=Command.Text}" />
<Setter Property="CommandTarget"
Value="{Binding ElementName=textBox}" />
</Style>
<Button x:Name="btnCut"
Click="btnCut_Click">
<Image Source="Icons/Cut.png" ToolTip="Cut" />
</Button>
<Button x:Name="btnCopy"
Click="btnCopy_Click"
Command="ApplicationCommands.Copy"
Style="{StaticResource textBoxCommands}">
<Image Source="Icons/Copy.png" ToolTip="Copy" />
</Button>
<Button x:Name="btnPaste"
Click="btnPaste_Click"
Command="ApplicationCommands.Paste"
Style="{StaticResource textBoxCommands}" >
<Image Source="Icons/Paste.png" ToolTip="Paste" />
</Button>
推荐答案
您不能以这种方式使用命令!该命令(使用方式)应位于菜单
或工具栏
中。
顺便说一句,由于您将要使用Commands,因此不需要那些click事件处理程序!
我建议您尝试将 DelegateCommand
添加到ViewModel,然后让该委托调用 ApplicationCommads
。
You can’t use command this way! The Command (in the way you use it) should be inside a Menu
or Toolbar
.
By the way, you don’t need those click event handler since you are going to use Commands!
I recommend you to try add DelegateCommand
to the ViewModel and let that delegate call ApplicationCommads
.
我强烈建议您阅读此
但是,作为一种快速的解决方案,请尝试以下操作(重要:记住,您需要在 TextBox
中选择一些文本,然后 Copy
和 Cut
将被启用):
I highly recommend you to read this http://msdn.microsoft.com/en-us/magazine/dd419663.aspx
But as a quick solution for you try the following (important: remember that you need to have some text selected in your TextBox
then Copy
and Cut
will be enabled):
<StackPanel HorizontalAlignment="Left" VerticalAlignment="Top">
<ToolBar>
<Button Content="Cut" Command="ApplicationCommands.Cut" Height="23" Width="75"/>
<Button Content="Copy" Command="ApplicationCommands.Copy" Height="23" Width="75"/>
<Button Content="Paste" Command="ApplicationCommands.Paste" Height="23" Width="75"/>
</ToolBar>
<TextBox Height="23" Name="textBox1" Width="120"/>
</StackPanel>
