Handling DataGridView Row Selection guide in WinForms with Custom DataSource
I'm working with a scenario with a `DataGridView` in my WinForms application where the selection of rows does not seem to reflect when I change the underlying data source. I'm using .NET Framework 4.8 and my `DataGridView` is bound to a custom list of objects. When I dynamically update the list, the `DataGridView` does not update its selection, and it seems like the selected row remains in a stale state. Here's what I have: ```csharp public class MyDataItem { public int Id { get; set; } public string Name { get; set; } } public partial class MyForm : Form { private BindingList<MyDataItem> dataItems; public MyForm() { InitializeComponent(); dataItems = new BindingList<MyDataItem>(); myDataGridView.DataSource = dataItems; } private void UpdateData() { // Clear and add new items dataItems.Clear(); dataItems.Add(new MyDataItem { Id = 1, Name = "Item 1" }); dataItems.Add(new MyDataItem { Id = 2, Name = "Item 2" }); myDataGridView.ClearSelection(); myDataGridView.Rows[0].Selected = true; // Trying to select the first row } } ``` When the `UpdateData()` method is called, it clears the previous items and adds new ones, but the selection does not visually update to the first row as intended. Instead, it remains on whatever row was selected before the update. I even tried calling `myDataGridView.Refresh()` after the selection change, but it didn’t help. I’ve also verified that the `DataGridView` is set to allow selection. It's set to `FullRowSelect`, but I still see this problematic behavior. Is there a specific property or event I need to handle to ensure that the selection updates correctly after refreshing the data source? Any insights or workarounds would be greatly appreciated! I'm working with C# in a Docker container on CentOS.
