TreeNode LabelEdit and Ctrl-C shortcut

TreeNode LabelEdit and Ctrl-C shortcut

• jonathanVerrier

  You can see the desired behavior in the Windows Explorer. Select a folder in the TreeView and right click for Rename. This is the state after TreeNode.BeginEdit() has been called. Now type Ctrl-C. It copies the selected label text to the clipboard. It does not copy the folder.

  I believe your suggestion is to have the OnMenuCopyClick handler (equivalent to the code to copy a folder in the example above) manage both the rename label text copy and the TreeNode copy by using a flag to indicate that rename is in progress How will I retrieve the TreeNode label text This would be available in the NodeLabelEditEventArgs label property for the BeforeLabelEdit or AfterLabelEdit events. But the editing is in progress.

  By the way, the TreeNode default context menu handles this correctly. Once TreeNode.BeginEdit() has been called, if you right click for the context menu, you can use the Copy there to copy the selected label text. Just not the Ctrl-C shortcut for copy.

  After posting my question yesterday, I continued searching and found this discussion:

  which suggests overriding the ProcessCmdKey method. But I don't understand what should be done in the override code.

  Hi,

  If you have Copy menuItem with an associated Ctrl-C shortcut. That is to say, if we press Ctrl-C, the behavior is just as we click the Copy Menu, so the OnMenuCopyClick will fire.

  So it seems to be contradictive scenario.

  So far I think we can use a flag, I am not sure about your concrete scenario about when you need to fire the OnMenuCopyClick related code.

  In the OnMenuCopyClick we can have a if statement to evaluate the flag to copy the lable onto clipboard directly or go the original OnMenuCopyClick code.

  If you still have any concern, please feel free to post here.

  Best regards,

  Thanks for your help. Here's what I ended up with. I added this to the form class.

  protected override bool ProcessCmdKey(ref Message msg, Keys keyData)

  {

  if (keyData == (Keys.Control | Keys.C) && renameFlag)

  {

  // Do not handle here, pass the keystroke along to other controls

  return false;

  }

  return base.ProcessCmdKey(ref msg, keyData);

  }

  Hi,

  Based on my research, you may try to add the code line in the Form, so that when we press Ctrl+C, both our Menu_click code will be called and the Lable text will be copied onto the clipboard.

  protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
  {
  base.ProcessCmdKey(ref msg, keyData);
  return false;
  }

  If you still have any concern, please feel free to post here.

  Best regards,
