How to pass a parameter to an event from a textbox in a gridview

I have a gridview with a textbox in an ItemTemplate, as below. The
OnTextChanged event fires okay but how do I pass a parameter to it, I get an
error when I try "OnTextChanged( ""SomeData" ")". I would also like to pass
in the value of column 1. I would also like to be able to get the row the
user is on when this event fires. Thank you for your help.

<asp:GridView ID="gv" />
<Columns>
<asp:BoundFie ld DataField="Col1 " HeaderText="Col umn 1"/>
<asp:TemplateFi eld HeaderText="Col umn2">
<ItemTemplate >
<asp:TextBox ID="txt" OnTextChanged=" OnTextChanged"
Autopostback=tr ue Columns=15 runat="server" Text='<%# Bind("Column2Da ta")
%>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateFie ld>
Protected Sub OnTextChanged(B yVal sender as Object, ByVal e as EventArgs)
'some procedures here
End Sub

You don't need to pass, you can figure it out in the event handler. The
sender parameter points on the textbox. The textbox is inside a TableCell.
The TableCell is inside a row. With this understanding you can navigate up
from the sender to the containing row using Parent property.

Thanks! that works great! This is my code if it helps anyone, quite simple!
Dim txt as TextBox

'get the cell the control that triggered this event is in

Dim parent1 as DataControlFiel dCell = sender.parent

'get the row the cell is in that the control is in that triggered this
event - got that?

Dim parent2 as Gridviewrow = parent1.parent

txt = cType(Parent2.F indControl("myC ontrol"), textbox)

'do whatever
