I want to know if an event occurs after editing a text node by double clicking.
Because I want to validate it.

Hi Yener,

Currently there is no built in support to fire an event after edit the TextNode. You can write your own delegate and call that function pointer after the EndEdit. Please refer to the following code snippet.

public delegate void NodeEndEdit(object sender, EventArgs e);
public event NodeEndEdit nodeEndEdit;

this.nodeEndEdit += new NodeEndEdit(MainForm_nodeEndEdit);
void MainForm_nodeEndEdit(object sender, EventArgs e)
Console.WriteLine("NodeEndEdit Event fired");

private void menuItem8_Click(object sender, EventArgs e)

if (m_editor.IsEditing)
this.nodeEndEdit(this, new EventArgs());

Please refer to the attached sample that demonstrates this completely.


In this sample when you double click on the text node you can edit it. Whne you click on Update->EndUpdate menuitem, an event will be triggered for the validation and it ends up the editing.

Please let me know if this helps.

I'm interested in this example but it doesn't work anymore. Could you post it again?

Thanks in advanced,
