bindinglist

I have a BindingList with my class where I would like to populate a ComboBox using a property of it so when my list changes the ComboBox would change as well. public class UserAccess { public override string ToString() { return Access; } public int AccessId { get; set; } public string Access { get; set; } public List<string> Command = new List<string>(); public bool HasCommand(string cmd) { return this.Command.Any(x => x == cmd); } } public BindingList<UserAccess> accessList = new BindingList<UserAccess>(); On my form load I assign it to the ComboBox: myComboBox.DataSource = accessList; I want

Time and time again I find myself having to write thread-safe versions of BindingList and ObservableCollection because, when bound to UI, these controls cannot be changed from multiple threads. What I'm trying to understand is why this is the case - is it a design fault or is this behavior intentional? JaredPar The problem is designing a thread safe collection is not simple. Sure it's simple enough to design a collection which can be modified/read from multiple threads without corrupting state. But it's much more difficult to design a collection that is usable given that it's updated from

I'm building a Windows Forms Application that displays a custom class Record objects and sorts them by how long they've been in my SortableBindingList<Record> record_list . When I start my program, I have some "dummy" records loaded into this list already for the sake of testing. The SortableBindingList<T> has been taken from here . public partial class Form1 : Form { public SortableBindingList<Record> record_list = new SortableBindingList<Record> { }; public static DataGridViewCellStyle style = new DataGridViewCellStyle(); public Form1() { InitializeComponent(); dataGridView.DataSource =

I am currently getting exceptions when modifying an IBindingList on multiple threads. Does anyone have a threadsafe version before I write my own? I think you'll find this an incredibly difficult task. The easier path would be to prevent multiple-thread access with a lock : void AddItemToList(object o) { lock(myBindingList) { myBindingList.Add(o); } } Look at the lock statement docs for more info. Only just found this post... do you mean like this ? 来源： https://stackoverflow.com/questions/148587/has-anyone-written-a-thread-safe-bindinglistt

How can I cast an IList<Customer> list to BindingList<Customer> ? LukeHennerley var yourList = new List<Customer>(); var listBinding = new BindingList<Customer>(yourList); BindingList Constructors You don't need to do a cast, just provide the BindingList<T> class constructor with IList<T> , which you have. Unfortunately you can not cast an IList to something its not. However you can create a new BindingList from it fairly easy by just passing your IList into its constructor. BindingList<Customer> bindingList = new BindingList<Customer>(yourIList); BindingList constructor takes IList parameter,

I am using Binding List in my application along with ItemChanged event. Is there any way I could know the previous values of properties in ItemChanged event. Currently I am adding a separate property named 'OldValue' to achieve this. Is there any way to know about the deleted item in item changed event. I am not able to find any way to know which item has been deleted from the list. If I understand correctly, you want to get info about item which was deleted from binding list. I think the easiest way to do this will be creating your own binding list which derives from binding list. Inside you

I have asked this question on MSDN forums as well ... http://social.msdn.microsoft.com/Forums/en/wpf/thread/4493988a-9bd8-48fe-aff0-348502136a80 I need to know that why Microsoft suggests that BindingList is not properly supported in WPF... What is it that doesnt work with BindingList in WPF? I find it pretty useful as it is. So far I personally have not found BindingList any slower or a having more load on memory. Plus WPF ItemsControls , ItemsTemplates , Styles , Hierarchies work great with BindingList s too. They are equally observable. Being a hardcore WPF developer myself and an
