Trouble Handling Mouse Wheel Events in Nested Panels with WinForms
I'm prototyping a solution and I'm working on a project and hit a roadblock. I'm having trouble with handling mouse wheel events in a nested panel structure using WinForms. I have a main form with a `Panel` that contains a `FlowLayoutPanel`, and inside that, there are multiple custom user controls. When I scroll the mouse wheel over the `FlowLayoutPanel`, nothing happens, and I need to allow scrolling functionality for the child controls. I've tried overriding the `OnMouseWheel` method in the parent panels but it doesn't seem to capture the events correctly. Here's what I've attempted so far: ```csharp public class CustomPanel : FlowLayoutPanel { protected override void OnMouseWheel(MouseEventArgs e) { // Try to scroll the panel this.AutoScrollPosition = new Point(0, this.AutoScrollPosition.Y + e.Delta); base.OnMouseWheel(e); } } ``` However, when I run the application, the scroll position does not update as expected. I even set `AutoScroll` to `true` on both the `Panel` and `FlowLayoutPanel`, but it still doesn't respond to the mouse wheel events properly. Additionally, I'm not getting any errors, but the scrolling just doesn't work. I’ve also tried manually calling `DoScroll` with different methods but to no avail. I’m using .NET Framework 4.8 and Visual Studio 2019. Is there a recommended way to ensure that the mouse wheel events propagate correctly to allow scrolling in nested panels? Any insights or alternative solutions would be greatly appreciated! Any feedback is welcome!
