Assuiming this is shown in a ListView
A1 - desc0 - 0
A1 - desc1 - 1
A1 - desc2 - 2
A1 - desc1 - 2
A2 - desc0 - 0
A2 - desc1 - 1
A3 - desc0 - 0
A3 - desc1 - 1

I have a list shown above. I want to filter it or just display a list with the specified value that I want. For example I just want to view all items that has a value of desc0 and desc2 with a marker of A1 and A3 with a page number of 0.

so the listview will only show:

A1 - desc0 - 0
A3 - desc0 - 0

Something like that. how should I do it? (kindly provide some code snippet)

I am having problems doing the filtering when i have a multiple specified items to be filtered.

are you using some kind of data binding to get these Listview items?

Solution 1

If you can bind a data source to your ListView, then LINQ is the better way to provide the same. For example entires in your ListView may be a collections of string or other objects, you can write query with the required condition.

listView1.DataSource = for str in strings where str.Contains( "desc0" ) or str.Contains( "desc2");

syntax may not be proper because I have tried this with VB

I hav'nt tried this with ListView

C#

public class SearchList
    {
        public string Name { get; set; }
        public string Desc { get; set; }
        public int Page { get; set; }
    }

static void Main()
{

List<SearchList> searchList = new List<SearchList> {new SearchList{Name="A1",Desc="desc0",Page=0 },
new SearchList{Name="A1",Desc="desc1",Page=1 },
new SearchList{Name="A1",Desc="desc2",Page=2 },
new SearchList{Name="A1",Desc="desc1",Page=2 },
new SearchList{Name="A2",Desc="desc0",Page=0 },
new SearchList{Name="A2",Desc="desc1",Page=1 },
new SearchList{Name="A3",Desc="desc0",Page=0 },
new SearchList{Name="A3",Desc="desc1",Page=1 }

};

var query = searchList.Where(a => a.Name == "A1" && a.Desc == "desc0" && a.Page == 1);
}
