GridLookUpEdit 多列 篩選 過濾

GridLookUpEdit  默認只按displayValue 的值進行自動匹配，

以下通過自定義可以實現多列自動匹配

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);

          }));

      }
