Get Deleted Item in ItemChanging event of BindingList

最后都变了- 提交于 2019-11-29 11:01:03
问题 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. 回答1: If I understand correctly, you want to get info about item which was deleted from binding list. I think

I have my enumHelper class that contains these: public static IList<T> GetValues() { IList<T> list = new List<T>(); foreach (object value in Enum.GetValues(typeof(T))) { list.Add((T)value); } return list; } and public static string Description(Enum value) { Attribute DescAttribute = LMIGHelper.GetAttribute(value, typeof(DescriptionAttribute)); if (DescAttribute == null) return value.ToString(); else return ((DescriptionAttribute)DescAttribute).Description; } my enum is something like: public enum OutputType { File, [Description("Data Table")] DataTable } So far so good. All the previous work

DataGridView sort and e.g. BindingList<T> in .NET

I'm using a BindingList<T> in my Windows Forms that contains a list of " IComparable<Contact> " Contact-objects. Now I'd like the user to be able to sort by any column displayed in the grid. There is a way described on MSDN online which shows how to implement a custom collection based on BindingList<T> which allows sorting. But isn't there a Sort-event or something that could be caught in the DataGridView (or, even nicer, on the BindingSource) to sort the underlying collection using custom code? I don't really like the way described by MSDN. The other way I could easily apply a LINQ query to

BindingList<T>.Sort() to behave like a List<T>.Sort()

I am attempting to write a SortableBindingList that I can use for my application. I have found lots of discussion about how to implement basic sorting support so that the BindingList will sort when used in the context of a DataGridView or some other bound control including this post from StackOverflow: DataGridView sort and e.g. BindingList<T> in .NET This is all very helpful and I have implemented the code, tested, etc. and it's all working, but in my particular situation, I need to be able to support a simple call to Sort() and have that call use the default IComparable.CompareTo() to do the

DataGridView with Button Control - Delete Row

百般思念 提交于 2019-11-27 08:58:57
I want a Delete button at the end of each row of DataGridView and by clicking that I want to remove the desired row from the binding list which is data source of my grid. But I can't seem to do it I have created a button object in product class and instantiated it with the unique id to remove that object from list. but button is not showing in the row. There are TextBoxes in the form and users can enter text, and when they press Add button, a new object of product is instantiated with the provided fields and then it is added to the BindingList . Finally this list is bound to the DataGridView
