datagrid same row change/alter

[Jason Gleason]

I have a question about the asp.net datagrid in c#. i have the following
grid...

<asp:datagrid id="RosterList " runat="server" Font-Names="Verdana"
BorderColor="Bl ack" GridLines="Vert ical"
cellpadding="4" Font-Name="Verdana" Font-Size="8pt"
AlternatingItem Style-CssClass="CartL istItemAlt"
AutoGenerateCol umns="False">
<AlternatingIte mStyle CssClass="CartL istItemAlt"></AlternatingItem Style>
<Columns>
<asp:BoundColum n HeaderText="Nam e" DataField="Mana gerName" />
<asp:TemplateCo lumn HeaderText="Tea m Code">
<ItemTemplate >
<asp:ListBox id="lstTeamCode " runat="server" Rows="1" />
</ItemTemplate>
</asp:TemplateCol umn>
<asp:TemplateCo lumn HeaderText="Tea m Name (Optional)">
<ItemTemplate >
<asp:Textbox id="newname" runat="server" Text="" />
</ItemTemplate>
</asp:TemplateCol umn>
</Columns>

Basically, when you change the selected index in the "lstTeamCod e" control,
i want to change the text of the "newname" text box. What's the easiest way
to code this? I can think of a few ways to jury rig it, but I wanted to know
the best/easiest way. Like how do I reference the particular "lstTeamCod e"
control for the particular row? How do I know what the datagrid row number
of the relevant "lstTeamCod e" control? I know I have to add the event to the
"lstTeamCod e" but i'm not sure how to reference the relevant "newname" text
box in the relevant row. Any suggestions?

Thanks.
