richTextBox UNDO / REDO

在myRichTextBox中键入一些文本后，单击 按钮或使用Ctrl + Z时没有任何反应...嗯......任何想法？ I''m using a richTextBox for editing a source code (with Syntax Highlighting)of my own programming language...How come that myRichTextBox doesn''t respond to Undo/Redo functions by usingdefault shortcut keys, or even programaticaly (by using Button_onClickevent)? if(myRichTextBox.CanUndo == true){myRichTextBox.Undo();} After typing some text into myRichTextBox, nothing happens when clicking thebutton, or using Ctrl+Z... Umm... any idea?推荐答案 你好乔， Hi Joe, 我正在使用richTextBox编辑源代码（使用语法高亮显示）我自己的编程语言... 为什么myRichTextBox不会通过使用默认快捷键，甚至programaticaly（通过使用Button_onClick 事件）来响应撤销/重做功能？ br /> if（myRichTextBox.CanUndo == true） { myRichTextBox.Undo（）; } 在myRichTextBox中输入一些文字后，单击按钮，或者使用Ctrl + Z ...嗯...任何想法？ I''m using a richTextBox for editing a source code (with Syntax Highlighting) of my own programming language...

Umm... any idea? 你确定你已经处理了KeyDown或MenuItem_Click事件吗？ 如果您有菜单和菜单项编辑/撤消那个menuitem的 快捷方式应该设置为Ctrl-Z。 撤消和按钮组合我没有任何问题。 /> 问候 Marcin Are You sure You have KeyDown or MenuItem_Click event handled? If You''ve got menu and menuitem "edit/undo" then that menuitem''sshortcut should be set to "Ctrl-Z".I didn''t have any problem with undo and button combination.

I double checked and debugged the code, so I''m pretty sure that Ihave set a good event. I''m pretty confused also! One more thing: you don''thave to set a shortcut for your menuItemUndo to get this work - just bypressing the default shortcut keys (Ctrl+Z) you''ll reach the Undo feature bydefault from Windows (I guess), but that''s NOT working for my RTB and Idon''t know why? 你好乔， Hi Joe, MarcinGrzêbski写道： Marcin Grzêbski wrote:你是确定您已经处理了KeyDown或MenuItem_Click事件？如果您有菜单和菜单项编辑/撤消那个menuitem'的快捷方式应该设置为Ctrl-Z...

Yo，Marcin！ ;）我的所有其他richTextBox都没有问题，只有这个......我仔细检查并调试了代码，所以我很确定我是已经设定了一个好事件。我也很困惑！还有一件事：你不必为menuItemUndo设置一个快捷方式来完成这项工作 - 只需按按下默认快捷键（Ctrl + Z）你就会达到撤销功能通过默认来自Windows（我猜），但那不适用于我的RTB而且我不知道为什么？ Yo, Marcin! ;) I don''t have problems either with all of my other richTextBox, just this one...

"Ctrl+Z" combination was working fine on RichTextBox control ;).... till i have set "Ctrl+Z" shortcut on single MainMenu''s menuitemCheck if You have any menuitem''s shortcut set to "Ctrl+Z" This is standard RichTextBox .NET control or it''s an inheritedcontrol or totaly new control?
