Howtoshowrows multiple times inside the footer template when

Question

Hi All,
My requirement is to copy multiple rows of grid view into footer row when user checks the check box present inside the grid view and clicks the copy row button out side of the grid.
Actually i have succeeded in copying single row but unable to copy multiple rows.
Please give me any idea or ref links.


My Design is....


<div>
<table style="width: 100%">
<tr>
<td>
<asp:Button ID="btncpyrws" runat="server" Text="CopyRows" Style="color: Blue; width: 100px"
OnClick="btncpyrws_Click" />
 
<asp:Button ID="btndlt" runat="server" Text="Delete" Style="color: Blue; width: 100px"
OnClick="btndlt_Click" OnClientClick="javascript:return dltmsg()" />
 
<asp:Button ID="btncrtrw" runat="server" Text="AddRow" Style="color: Blue; width: 100px"
OnClick="btncrtrw_Click" />
</td>
</tr>
<tr>
