如何在ASP.NET C＃中为按钮分配动态ID

Question

I have created html table and getting dynamic data in table. But on each button I am calling function, My server side should understand this button. so I need to set dynamic id or name to button. Below is my code. I want to give unique id to submit button.

<table cellspacing='0'> <!-- cellspacing='0' is important, must stay -->

    <!-- Table Header -->

        <tr>
           <th>ID</th>
           <th>Name</th>
           <th>Email</th>
           <th>Subject</th>  
           <th>Action</th>
   </tr>


    <!-- Table Header -->

    <!-- Table Body -->

        <%for (int i = 0; i < row_count; i++) { %>
    <tr id="h<%=i%>"><td><%=list[0][i]%></td>
        <td><%=list[1][i]%></td>
        <td><%=list[2][i]%></td>
        <td><%=list[3][i]%></td>
        <td><%=list[4][i]%></td>

        <td></td>

        <td><button type="submit" id="Submit"  class="submit" runat="server" onserverclick="button_Click" > Approve</button>
        </td>
    </tr>
    <%} %>


    <!-- Table Body -->

</table>

I tried to assign id as below but did't worked.

<td><button type="submit" id="Submit<%=i%>"  class="submit" runat="server" onserverclick="button_Click" > Approve</button>
        </td>
