Thanks for your help. I have a question about the exact
syntax to use. My table ends up with four rows, but the
aspx source just looks like this for textbox:
<input type="text" name="TextBox2" id="TextBox2"
DATAFLD="Date" runat="server">
and like this for dropdown:
<asp:DropDownList id="SelectWeight" DATAFLD="Weight"
runat="server">
<asp:ListItem></asp:ListItem>
<asp:ListItem Value="100">100</asp:ListItem>
<asp:ListItem Value="200">200</asp:ListItem>
<asp:ListItem Value="300">300</asp:ListItem>
</asp:DropDownList>
Where should I add the custom attribute? And are there any
syntax or value rules?
Thanks again! I really appreciate the help.
