You can assign the id in the html view of your aspx page. Here is some sample code where the id is assigned:

<asp:repeater id="DataInputTableElements" datasource=<%# items %>
runat="server">
      <itemtemplate>
          <tr>
              <th>
                   time<%# Container.DataItem %>
              </th>
              <td>
                   <asp:textbox id="TextBox1"
                        cssclass="TextInput" runat="server" />
              </td>
              <th>
                   time<%# Container.DataItem %>
              </th>
              <td>
                   <asp:textbox id="TextBox2"
                        cssclass="TextInput" runat="server" />
              </td>
            </tr>
    </itemtemplate>
</asp:repeater>

Then to iterate through the Textboxes inside the repeater you would use the foreach loop like below:

foreach (RepeaterItem ri in myRepeater.Items)
   {
    // get the txtbox
    TextBox txt = ((TextBox)ri.FindControl("myTextbox"));
   }
