How to Handle Data Binding in WinForms to Prevent Data Loss during UI Updates?
I'm testing a new approach and I'm sure I'm missing something obvious here, but Hey everyone, I'm running into an issue that's driving me crazy. I'm working on a WinForms application using .NET Framework 4.8, where I need to bind a `BindingList<T>` to a `DataGridView`. However, I encountered an scenario when trying to update the `BindingList` while the UI is being populated. After adding several items to the list and updating the UI, I noticed that some items are not displaying correctly, or worse, I receive the behavior: `InvalidOperationException: Collection was modified; enumeration operation may not execute.` I’ve already attempted to create a method that wraps the data update in `BeginInvoke` to ensure that the UI updates are on the UI thread. Here’s a simplified version of my code: ```csharp private BindingList<MyData> myDataList = new BindingList<MyData>(); private void LoadData() { myDataGridView.DataSource = myDataList; for (int i = 0; i < 100; i++) { myDataList.Add(new MyData { Name = "Item " + i }); } } private void UpdateData() { this.BeginInvoke((MethodInvoker)delegate { // Simulate some data processing for (int i = 0; i < 10; i++) { myDataList.Add(new MyData { Name = "New Item " + (i + 100) }); } }); } ``` While this approach does prevent the cross-thread operation exception, I still face the data loss scenario where items show up as blank or are missing altogether. I also tried temporarily suspending the binding with `myDataList.RaiseListChangedEvents = false;` before making updates, but it led to further complications. Can someone suggest how to properly manage UI updates without risking data loss or throwing exceptions? Are there best practices for handling such scenarios in WinForms? How would you solve this? Has anyone else encountered this? Cheers for any assistance!
