如何使用数据源按需过滤gridview中的数据 [英] How to filter data from gridview on demand by using datasource

问题描述

我已经使用数据源绑定了gridview，然后如何通过特定的选择couloumn值来过滤它？

I have binded the gridview by using datasource then how to filter from it by perticular selecting couloumn value?

推荐答案

数据网格有一个过滤属性。构建过滤器对象并将其分配给过滤器属性。您不要过滤数据源中的数据......这将导致重大问题。让网格在视图中按照预期进行过滤。



特定数据网格的文档应该包含有关执行此操作的信息。

Data grids have a filter property. Build up a filter object and assign it to the filter property. You DO NOT filter the data at the datasource... That will cause major problems. Let the grid do the filtering in the view like it is supposed to.

The documentation for your specific data grid should have information on doing this.

请阅读我对该问题的评论。



我建议使用 Google [ ^ ]。有很多例子可供选择，例如：

带有过滤器的ASP.NET Gridview [ ^ ]

演练：使用LinqDataSource和GridView控件选择和过滤数据子集 [ ^ ]

I'd suggest to use Google[^]. Tons of examples are available, for example:
ASP.NET Gridview with Filter in Header[^]
