Convert generic list to BindingList<T>

Question

I have BindingList object which is attched with DataGridView.

BindingList<FilesToProcessDataModels> Listfiles = new BindingList<FilesToProcessDataModels>();
dataGridFiles.DataSource = Listfiles;

I want to filter items list by given condition in Where. like following:

dataGridSheets.DataSource = Listfiles.Where(i => i.Status == FileStatus.NotProcessed).ToList();

Above code is working fine but I want to assign filter resut to the same type object [Listfiles] instead datagrid,

When I am doing this:

Listfiles = Listfiles.Where(i => i.Status == FileStatus.NotProcessed).ToList();

it gives following erorr

[Cannot implicitly convert type 'System.Collections.Generic.List to BindingList']

How can I convert generic list to BindingList<FilesToProcessDataModels>?

Answer 1

below is the standard way - tho google should show this up easily -even on SO:

Convert IList<T> to BindingList<T>

var listFiles= new List<FilesToProcessDataModels>();
var listBindingFiles = new BindingList<FilesToProcessDataModels>(listFiles);

Dendro

Actually I am using derived class from BindingList. SortableBindingList<T> : BindingList<T>. I just called two base constructor from derived class 1. 'public SortableBindingList(IList<T> collection) : base(collection){}' 2. 'public SortableBindingList() : base(){}'. Now it is working perfectly. Thanks – Adriel

Answer 2

Like this:

var yourList = new List<FilesToProcessDataModels>();
var listBinding = new BindingList<FilesToProcessDataModels>(yourList);

@jimtollan Yeah, too bad Zeeshanef didn't take the 20 seconds to search for it on google (or SO) before creating a new question. – Penalty

Answer 3

Listfiles = Listfiles.Where(i => i.Status == FileStatus.NotProcessed).ToList();

I think you had defined ListFiles as BindingList<> bit now you are trying to assign a List<> to it.

That is the cause of that error
