How to create a custom control dynamically? - asp.net

Question

Let me get this straight. I manage to create a custom Gridview with a single checkbox but my problem here is that I want to include multiple dynamic Checkbox.
Here is my code:
<%# Control Language="C#" AutoEventWireup="true" EnableTheming="true" CodeFile="GridviewControl.ascx.cs" Inherits="UserControl_GridviewControl" %>
<link href="../Template/CSS/Style.css"type="text/css" rel="Stylesheet" />
<div>
<span id="Span5" style="font-family: Arial; font-size:12px;" ><asp:Label ID="lblCount" runat="server" Text="0" Font-Bold="true"></asp:Label>
Record/s</span>
<span class="maintenance-btns">
<asp:Button ID="btnNew" runat="server" Text=" New " onclick="btnNew_Click"/>
<asp:Button ID="btnDel" runat="server" Text=" Delete " onclick="btnDel_Click"/>
</span>
</div>
<asp:Panel ID="pnlPc" runat="server" CssClass="div-grid" ScrollBars="Auto">
<asp:GridView ID="gvListing" runat="server" AllowPaging="True" AutoGenerateSelectButton="true"
OnRowDataBound="gvListing_RowDataBound" skinid="gvListing"
onselectedindexchanged="gvListing_SelectedIndexChanged"
onpageindexchanging="gvListing_PageIndexChanging" PageSize="50" >
<FooterStyle CssClass="grid-footer" />
<Columns>
<asp:TemplateField HeaderText="CheckAll">
<HeaderTemplate>
<asp:CheckBox ID="chkSelectAll" runat="server" AutoPostBack="true"
OnCheckedChanged="chkSelectAll_CheckedChanged" CssClass="select-all"/>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="chkSelect" runat="server" AutoPostBack="true"
OnCheckedChanged="chkSelect_CheckedChanged" CssClass="listing-checkbox"/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</asp:Panel>
In this gridview I only have a checkboxes at the first column. I want to put the dynamically generated checkboxes at the last column.
P.S.: How do I retrieve the id with those dynamically create checkboxes?

You can do like this
protected void gvData_DataBound(object sender, EventArgs e)
{
foreach (GridViewRow objRow in gvData.Rows)
{
TableCell tcCheckCell = new TableCell();
var checkBox = new CheckBox();
checkBox.CheckedChanged += checkBox_CheckedChanged;
tcCheckCell.Controls.Add(checkBox);
objRow.Cells.AddAt(0, tcCheckCell);
}
}
void checkBox_CheckedChanged(object sender, EventArgs e)
{
//do something
}
