Dynamically resizing of text box

Hi,
My code is

<ItemTemplate>
<asp:TextBox id="txtNote" TextMode="MultiLine" wrap="true" Columns="30" Rows="3" runat="server" Font-Names="Verdana" Font-Size="XX-Small"></asp:TextBox>
</ItemTemplate>

My constraint is that I dont want to fix the colums and rows by hardcoding.I want that it should dynamically resize itself.

in DataBound event

find the text box in Grid Row by

Code:

---

TextBox box = e.FindControl("txtNote") as TextBox;

---

and set its new values by

Code:

---

box.Height = 50;
box.Width = 100;

---
