ContextMenuStri p - determine source while using keyboard shortcut

[ommail]

I have two RichTextBox controls on a form, and single
ContextMenuStri p
control which serves for both textboxes.

I need to determine which RichTextBox control invokes an event handler
in
ContextMenuStri p.

So I use that code:
private void pasteToolStripM enuItem_Click(o bject sender, EventArgs e)
{
((RichTextBox)c ontextMenuStrip .SourceControl) .Paste();
}

It works good if I press right mouse button and select paste item,
but if I try Ctrl+V instead of use mouse I get NullReferenceEx ception.

What to do, to make this thing work both for using mouse and keyboard
shortcut?

Regards

This problem has occured since you have specified Ctrl+V as shortcut
key for paste. In that case if we press Ctrl + V the SourceControl for
contextmenu will not be set and will be null. Just check the
condition.

private void pasteToolStripM enuItem_Click(o bject sender, EventArgs e)
{
if (contextMenuStr ip1.SourceContr ol == null)
{
foreach( Control ctrl in this.Controls)
{
RichTextBox activeBox = ctrl as RichTextBox;
if (activeBox != null && activeBox.Conta insFocus)
activeBox.Paste ();
}
return;
}
((RichTextBox)c ontextMenuStrip 1.SourceControl ).Paste();
}

If you don't want to use this type of logic, you can remove the
shortcut key on context menu. Richtextcontrol will auto detect Ctrl+V
combination and paste data from clipboard.

explicitly, Ctrl+V for context menu item will be detected.

I try this simple solution and it works fine:
private void kopiujToolStrip MenuItem_Click( object sender, EventArgs e)
{
RichTextBox control = ActiveControl as RichTextBox;
if (control != null)
{
control.Copy();
}
}
