如何筛选使用Visual Studio创建的C＃Winform datagridview

Question

I'm astonished there isn't even a filter property attached to datagridview and I'm getting on my nerve, I can find examples for filtering Datagridview that was binded programmatically, I cannot find any example on how to filter a datagridview that was generated by Visual Studio.

So please can someone tell me how to filter this stuff ?

Thanks.

Answer 1

在BindingSource上放置一个过滤器：

bindingSource.Filter = "Age < 21";

Answer 2

You place the filter on the DataSource that is driving your DataGridView - for example, I have this code on a DataGridView that allows for user filtering and is called on a postback:

VisitsDataSource.FilterExpression = "1 = 2";
GridView1.DataBind();

Answer 3

Take a look at this post here . You have provide a BindingSource as the DataSource of the DataGridView rather than the DataTable itself.

BindingSource source1 = new BindingSource();
source1.DataSource = yourDataTable;    

//The Filter string can include Boolean expressions.
source1.Filter = "email='samikram@live.com'"

// Set the data source for the DataGridView.
datagridview1.DataSource = source1;

Thanks JustinD, I suppose you talk about ASP.NET.

I forgot to say I'm using Winform with BindingSource.
