Interaction and Behavior

This feature provides mechanisms for managing user interactions, including drag-and-drop support and smooth scrolling, ensuring a dynamic and responsive experience within the SiticoneFlowPanel control

Overview

The Interaction & Behavior feature enables developers to create interactive UIs by facilitating control dragging, drop operations, and animated scrolling. Core functionalities include enabling drag-and-drop interactions via the EnableDragDrop property and managing item dragging events with ItemDragging. In addition, smooth scrolling is implemented to bring specific controls into view seamlessly, enhancing the user experience during navigation.

3. Code Examples

Example 1: Enabling Drag-and-Drop

The following code snippet demonstrates how to enable drag-and-drop for controls within the SiticoneFlowPanel and subscribe to the ItemDragging event to track user interactions.

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

namespace InteractionDemo
{
    public partial class MainForm : Form
    {
        private SiticoneFlowPanel flowPanel;

        public MainForm()
        {
            InitializeComponent();
            InitializeFlowPanel();
        }

        private void InitializeFlowPanel()
        {
            flowPanel = new SiticoneFlowPanel
            {
                Dock = DockStyle.Fill,
                EnableDragDrop = true, // Enable drag-and-drop functionality
                EnableSmoothScrolling = true
            };

            // Subscribe to the ItemDragging event for custom feedback
            flowPanel.ItemDragging += FlowPanel_ItemDragging;

            // Add sample controls to the panel
            for (int i = 0; i < 5; i++)
            {
                Button btn = new Button
                {
                    Text = $"Drag Me {i + 1}",
                    Width = 100,
                    Height = 30,
                    BackColor = Color.LightBlue
                };
                flowPanel.Controls.Add(btn);
            }

            Controls.Add(flowPanel);
        }

        private void FlowPanel_ItemDragging(object sender, SiticoneFlowPanel.ItemDragEventArgs e)
        {
            // Provide visual feedback or custom logic during drag
            Console.WriteLine($"Dragging control: {e.DraggedItem.Text} at {e.Location}");
        }
    }
}

Example 2: Smooth Scrolling to a Specific Control

This example demonstrates how to scroll the panel to a specific control with animation enabled, ensuring that the target control is brought into view smoothly.

using System;
using System.Windows.Forms;
using SiticoneNetFrameworkUI;

namespace InteractionDemo
{
    public partial class MainForm : Form
    {
        private SiticoneFlowPanel flowPanel;

        public MainForm()
        {
            InitializeComponent();
            InitializeFlowPanel();
        }

        private void InitializeFlowPanel()
        {
            flowPanel = new SiticoneFlowPanel
            {
                Dock = DockStyle.Fill,
                EnableSmoothScrolling = true
            };

            // Add sample controls to the panel
            for (int i = 0; i < 10; i++)
            {
                Button btn = new Button
                {
                    Text = $"Button {i + 1}",
                    Width = 100,
                    Height = 30
                };
                flowPanel.Controls.Add(btn);
            }

            Controls.Add(flowPanel);

            // Scroll to the 5th button after a delay
            Timer timer = new Timer { Interval = 1000 };
            timer.Tick += (s, e) =>
            {
                timer.Stop();
                Button targetButton = flowPanel.Controls[4] as Button;
                if (targetButton != null)
                {
                    flowPanel.ScrollToControl(targetButton, animate: true);
                }
            };
            timer.Start();
        }
    }
}

---

5. Best Practices

Best Practice	Recommendation
Enable Only When Necessary	Activate EnableDragDrop only when the use case requires user repositioning to avoid unintended behavior.
Provide Clear Visual Feedback	Utilize the ItemDragging event to update the UI (e.g., highlighting a control) during drag operations for better usability.
Test Smooth Scrolling Behavior	Ensure that smooth scrolling functions correctly under different scenarios and on various hardware configurations.
Handle Event Cleanup	When subscribing to events like ItemDragging, ensure proper unsubscription if the panel is disposed or the event is no longer needed.

---

6. Common Pitfalls

Pitfall	Explanation	How to Avoid
Unresponsive Drag Operations	Failing to manage state during drag operations might cause the UI to become unresponsive.	Ensure that drag events are handled efficiently and provide immediate feedback to the user.
Conflicts with Other Interaction Features	Enabling multiple interactive features simultaneously without proper coordination can lead to unpredictable behavior.	Test the integration of drag-and-drop with smooth scrolling to ensure they work harmoniously together.
Overlooking Event Unsubscription	Not unsubscribing from the ItemDragging event when the control is disposed can lead to memory leaks.	Always unsubscribe from events in the control's Dispose method or when the functionality is no longer required.
