dev gridcontrol設置過濾器下拉列表

 

  

調用：
            //為類別名稱列啟用選中的過濾器下拉式樣式。
            this.gridView1.Columns[4].OptionsFilter.FilterPopupMode = FilterPopupMode.CheckedList;
            //訂閱ShowFilterPopupCheckedListBox事件。（允許您在顯示之前定制選中的過濾器下拉列表。）
            this.gridView1.ShowFilterPopupCheckedListBox += new FilterPopupCheckedListBoxEventHandler(this.gridView1_ShowFilterPopupCheckedListBox);


        /// <summary>
        /// 
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        public void gridView1_ShowFilterPopupCheckedListBox(object sender, DevExpress.XtraGrid.Views.Grid.FilterPopupCheckedListBoxEventArgs e)
        {
            //忽略非目標列，視具體情況而定
            if (e.Column.FieldName != "Address") return;
            //是否不隱藏“選擇所有”項，true不隱藏，false隱藏
            e.CheckedComboBox.SelectAllItemVisible = true;
            //定位和禁用包含特定值的檢查項。
            for (int i = 0; i < e.CheckedComboBox.Items.Count; i++)
            {
                DevExpress.XtraEditors.Controls.CheckedListBoxItem item = e.CheckedComboBox.Items[i];
                string itemValue = (string)(item.Value as FilterItem).Value;
                //設置對應選項不可選
                //if (itemValue == "湖南")// || itemValue == "Condiments")
                //{
                //    e.CheckedComboBox.Items[i].Enabled = false;
                //}
            }
        }

 注意調用時要存在對應的列。
