I have a table with two fields: UserID and UserName.

In a GridView, I want to display a list of UserNames, with each UserName appearing as a hyperlink:

DataNavigateURLFormatString: destinationpage.aspx?UserID={0}

I have two questions:

1. How do I set the DataFormatTextString to the contents of UserName?
2. How do I hide the UserID and UserName fields from my GridView?

TIA!

  To hide field in gridview just set "visible=false" for that template field
e.g
 <asp:TemplateField Visible ="False" HeaderText="RateID">
                  <ItemTemplate>
                       <asp:TextBox id="txtRateID" Visible ="false" Text = '<%# Eval("rate_id") %>' runat="server" Width="50px" Height="15px"></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>

Thank you! I got it working exactly the way I wanted it to from your post.
