Dev控件库中Grid控件中下拉框级联显示
这个grid控件可以绑定多个下拉列表来进行级联显示吗?ColumnEdit属性只是针对一列的,
能够做到只设置指定的单元格中的combobox的数据源吗? devexpress gridcontrol combobox --------------------编程问答-------------------- 自己找到方法了。主要是在这个事件中实现的CustomRowCellEditForEditing
--------------------编程问答-------------------- 您好:我刚刚接触DEVExpress,combobox的级联显示已经搞了2天了,还是很模糊,你的这段程序我仔细看过了,可是还是搞不太清楚整个流程,可以告诉我你程序中的字段是来自同一张表还是不同的表吗?十分感激
DevExpress.XtraGrid.Views.Grid.GridView view = sender as DevExpress.XtraGrid.Views.Grid.GridView;
RepositoryItemComboBox cbx = new DevExpress.XtraEditors.Repository.RepositoryItemComboBox();
switch (e.Column.FieldName)
{
case "DBConstructionName":
cbx.Items.Clear();
cbx.Items.AddRange(constructions.Select(c => new Models.ComboBoxItemTextValue<int>(c.ConstructionID, c.ConstructionName)).ToList());
cbx.SelectedValueChanged += new EventHandler(cbx_SelectedValueChanged);
e.RepositoryItem = cbx;
break;
case "DBBuildingName":
buildingBll = new BLL.Building(Login.UserId, Login.Password);
string constructid = view.GetRowCellDisplayText(e.RowHandle, "DBConstructionID");
//楼栋
buildingIListByDataBase = buildingBll.GetBuilding(iCityID, Convert.ToInt32(constructid), 0);
cbx.Items.Clear();
cbx.Items.AddRange(buildingIListByDataBase.Select(b => new Models.ComboBoxItemTextValue<int>(b.BuildingID, b.BuildName)).ToList());
cbx.SelectedValueChanged += new EventHandler(cbx_SelectedValueChanged);
e.RepositoryItem = cbx;
break;
case "DBHouseName":
houseBll = new BLL.House(Login.UserId, Login.Password);
string bid = gvwFetchData.GetRowCellValue(e.RowHandle, "DBBuildingID").ToString();
//房号
house = houseBll.GetHouseList(Convert.ToInt32(bid), 0, iCityID);
cbx.Items.Clear();
cbx.Items.AddRange(house.Select(h => new Models.ComboBoxItemTextValue<int>(h.HouseID, h.HouseName)).ToList());
cbx.SelectedValueChanged += new EventHandler(cbx_SelectedValueChanged);
e.RepositoryItem = cbx;
break;
default: break;
}
cbx.ParseEditValue += new ConvertEditValueEventHandler(cbx_ParseEditValue);
