combobox聯(lián)動(dòng)　

DataTable dtjrh = sb.SelectSyscode(2, true);if (dtjrh.Rows.Count > 0){cbb_jrh.DataSource = dtjrh;cbb_jrh.DisplayMember = "name";cbb_jrh.ValueMember = "id";this.cbb_jrh.SelectedIndex = 0;}yewubind(cbb_jrh.SelectedValue.ToString());

　　

獲取選中項(xiàng)　

foreach (Control c in panel1.Controls){foreach (DataRowView dr in ((CheckedListBox)c).CheckedItems){yewuid += dr["id"].ToString() + ";";}}

　　最后清空

panel1.Controls.Clear();this.cbb_jrh.SelectedIndex = 0;
