Answer 1

Try this

Simply use <%: list[i] %> instead of <% list[i].ToString(); %>

<table id="table1">
        <% var list = this.GetData();
           for (int i = 0; i < list.Count(); i++)
           { %>
        <tr>
            <td>
                <%: list[i] %>
                //list items are not shown on webpage
            </td>
        </tr>
        <%}
        %>
</table>

But you should consider Repeater and other data binding controls provided by Microsoft already for this purpose.
