绑定源未获得过滤器 [英] Binding Souce not getting filter

问题描述

我的代码是这样的

My code is like this

BindingSource bs=new BindingSource();
List<items> lstItems= ListItems();
bs.DataSource=lstItems;
//I bind this bindingsouce to a gridview.
grd.DaataSource=bs;
//Then I copy this original BindingSource to a separate BindngSource
BindingSource filterBs=new BindingSource();
//Then I use a filter condition to Bindingsource
filterBs.Filter= "ItemCode=''1'' and cost>''200''";
grd.DataSource=null;
//Re binding the datasouce of the grid to the filtered bindingsource.
grd.DataSource=filterBs;</items>

但是现在它也显示了网格中的所有记录.

But now also it shows all records in the grid.

推荐答案

由于Cost是一个数字字段，因此您的过滤器不应读取

As Cost is a numeric field, should your filter not read

filter.Bs.Filter = "ItemCode = '1' AND cost > 200";

您为了将来更容易阅读，请在将来的代码块中输入您的代码?

Could you please enter your code in pre blocks in the future, to make it easier to read?
