GridLookUpEdit 多列 筛选 过滤

GridLookUpEdit  默认只按displayValue 的值进行自动匹配，

以下通过自定义可以实现多列自动匹配

Code和name 是列名。

  void gridLookUpEdit1_Popup(object sender, EventArgs e)
        {
            FilterLookup(sender);

        }

        private  void FilterLookup(object sender) {
            Text += " ! ";
            GridLookUpEdit edit = sender as GridLookUpEdit;
            GridView gridView = edit.Properties.View as GridView;
            FieldInfo fi = gridView.GetType().GetField("extraFilter", BindingFlags.NonPublic | BindingFlags.Instance);
            Text = edit.AutoSearchText;
            BinaryOperator op1 = new BinaryOperator("Code", edit.AutoSearchText + "%", BinaryOperatorType.Like);
            BinaryOperator op2 = new BinaryOperator("Name", edit.AutoSearchText + "%", BinaryOperatorType.Like);
            string filterCondition = new GroupOperator(GroupOperatorType.Or, new CriteriaOperator[] { op1, op2 }).ToString();
            fi.SetValue(gridView, filterCondition);

            MethodInfo mi = gridView.GetType().GetMethod("ApplyColumnsFilterEx", BindingFlags.NonPublic | BindingFlags.Instance);
            mi.Invoke(gridView, null);
        }


        private void gridLookUpEdit1_EditValueChanging(object sender, ChangingEventArgs e) {
            this.BeginInvoke(new System.Windows.Forms.MethodInvoker(delegate{
                FilterLookup(sender);
            }));
        }
