Passing parameters to a eventhandler?

Question

Hi.  I have an image tagging feature on a media program I'm writing.  I want to have a grid of textboxes where the user can type in tags they tend to use a lot, then they can double click the textbox to insert the tag.  I did some reading on how to programmatically create controls and eventhandlers with parameters and I am at this point:
for (int cnt = 0; cnt textbox_DoubleClick(cnt.ToString());
tabPage7.Controls.Add(txt);
}
private void textbox_DoubleClick(object id) {
MessageBox.Show(id.ToString());
}
That creates the controls fine.  However, no matter which one I double click the messagebox says "5".  I changed out cnt.tostring and put "test" and got my "test" fine.  Why doesn't it work with the passing of the iterator?  Does it perhaps view the "cnt.ToString" as something to process at double click time literally; like pass the value of cnt variable instead of 1,2,3?  If so, how do I get around that?
I just need to be able to identify in the event fired function what textbox called the func so I know what text to paste.  Ugh!
Thanks.

Well, I figured it out.  I don't know how efficient this is, but it works:
for (int loop = 1; loop textbox_DoubleClick(txt.Name);
tabPage7.Controls.Add(txt);
}
}
private void textbox_DoubleClick(object id) {
Control[] grr = this.Controls.Find(id.ToString(), true);
if (!ExistingTags.Lines.Contains(grr[0].Text.ToLower())) ExistingTags.Text += grr[0].Text.ToLower() + Environment.NewLine;
}
