devExpress.XtraGrid.GridControl winform和c＃中的两个链接lookupEdit

Question

我有问题。例如;

gridControl at 3.columns 5.cells in lookUpEdit datasource binding 或动态1.columns 5.cells，2.columns 5.cells ... in lookUpEdit datasource binding。

• datasource：firebird或sqlServer（dataset）
• 组件：devExpress gridControl gridView

提前致谢...

Answer 1

我相信，您应该使用How to filter a second LookUp column based on a first LookUp column's value）知识库文章中展示的方法：

void gridView1_ShownEditor(object sender, EventArgs e) {
    ColumnView view = (ColumnView)sender;
    if (view.FocusedColumn.FieldName == "CityCode" && view.ActiveEditor is LookUpEdit) {
        LookUpEdit edit = (LookUpEdit)view.ActiveEditor;
        string countryCode = (string)view.GetFocusedRowCellValue("CountryCode");
        edit.Properties.DataSource = GetFilteredCities(countryCode);
    }
}

请参阅How to filter a second LookUp column based on a first LookUp column's value示例，其中显示了此方法。
