Use a data control. Place the textboxes in the itemtemplate and bind the control. Something like this(according to image)
<asp:Repeater ID="rptDocuments" runat="server" >
<ItemTemplate>
<tr>
<td >
<asp:TextBox ID="TextBox1" runat="server" Width="10" Visible="false" Text='<%# DataBinder.Eval(Container.DataItem,"ColumnName") %>'></asp:TextBox>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
