I have Found The Answer. In Case You Guys Are Still Searching For It Have A Look :

Here is the Code Behind:

protected void rptcomment_ItemCommand(object source, System.Web.UI.WebControls.RepeaterCommandEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        Panel replypic = (Panel)e.Item.FindControl("replypic");
        Panel replywrite = (Panel)e.Item.FindControl("replywrite");
        if (e.CommandName == "img_Click") // check command is cmd_delete
        {
            // get you required value
            string CustomerID = (e.CommandArgument).ToString();
            replypic.Visible = true;
            replywrite.Visible = true;
        }
    }
}
