 private void RadioButton_Bind()
    { cmdstr = "select ID,ProfileRbnName from Profile_RbnFilter";
        DataSet ds = new DataSet();
        SqlDataAdapter adp = new SqlDataAdapter(cmdstr, con);
        adp.Fill(ds);
        RbnFilter.DataSource = ds.Tables[0];
        RbnFilter.DataValueField = "ID";
        RbnFilter.DataTextField = "ProfileRbnName";
        RbnFilter.DataBind();
    };
