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);  

        }));

}
