Hi Stephen,
You can use the data from the dataset to bind to a textbox or other control
but you use it somewhat differently. You have to decide which value you want
to use from the dataset, assuming there's more than one.
Here's some sample code that might get you started. Let us know if it helps?

Text="Button"></asp:button></p>
