You may set the id of the checkbox which you have created to the following

bx.ID = "ChkBox_" + i.ToString();

and in your

C#

protected void CheckBox_CheckedChanged(object sender, EventArgs e)
{
        CheckBox chkbox = (CheckBox)sender;
        string chkboxName = chkbox.ID.Split('_')[1];
        Response.Write(chkboxName);
}

This has worked for me I not sure if this the solution you require.
