Shadow & Animation Effects

This feature enables the addition of animated drop shadows and blink effects to the card number control, creating depth and dynamic visual feedback during user interactions.

Overview

The Shadow & Animation Effects feature provides a range of properties to control the appearance, timing, and behavior of drop shadows and animations. Developers can enable or disable drop shadows, configure their color, blur, and opacity, and control blink effects with customizable animation durations and counts. These effects improve the visual appeal of the control and offer additional feedback to users during interactions such as focus and hover.

Property Details

The table below summarizes the key properties associated with shadow and animation effects:

Property	Description	Default Value / Notes
EnableDropShadow	Enables or disables the drop shadow effect around the control.	false by default
ShadowColor	Specifies the color of the drop shadow.	Typically a semi‑transparent black (e.g., Color.FromArgb(15, Color.Black))
ShadowBlur	Sets the blur radius of the shadow effect, affecting its softness.	An integer value (e.g., 10)
BlinkShadow	Determines whether the shadow will blink (animate its opacity).	false by default
ContinuousBlink	When enabled, causes the shadow blink effect to run continuously.	false by default
BlinkCount	Specifies the number of blink cycles if BlinkShadow is enabled and ContinuousBlink is false.	3 by default
ShadowAnimationDuration	Duration (in milliseconds) for the shadow fade in/out animation.	1 (or a user‑defined positive value)

Code Examples

Example 1: Enabling a Basic Drop Shadow

This example demonstrates how to enable a drop shadow with a custom blur and color.

// Create an instance of the SiticoneCardNumberBox control
SiticoneCardNumberBox cardNumberBox = new SiticoneCardNumberBox();

// Enable drop shadow and configure its appearance
cardNumberBox.EnableDropShadow = true;
cardNumberBox.ShadowColor = Color.FromArgb(50, 0, 0, 0);  // Semi-transparent black
cardNumberBox.ShadowBlur = 12;  // Increase blur radius for a softer shadow

// Add the control to the form
this.Controls.Add(cardNumberBox);
cardNumberBox.Location = new Point(20, 20);
cardNumberBox.Size = new Size(300, 50);

Example 2: Configuring a Blink Effect for the Shadow

The following example shows how to configure the shadow to blink, providing dynamic feedback.

// Create the control instance
SiticoneCardNumberBox cardNumberBox = new SiticoneCardNumberBox();

// Enable drop shadow and set blink properties
cardNumberBox.EnableDropShadow = true;
cardNumberBox.ShadowColor = Color.FromArgb(40, Color.Black);
cardNumberBox.ShadowBlur = 10;
cardNumberBox.BlinkShadow = true;
cardNumberBox.BlinkCount = 4;  // The shadow will blink 4 cycles
cardNumberBox.ContinuousBlink = false;  // Blink for a fixed number of times
cardNumberBox.ShadowAnimationDuration = 200;  // Set animation duration to 200 ms

// Add the control to the form
this.Controls.Add(cardNumberBox);
cardNumberBox.Location = new Point(20, 100);
cardNumberBox.Size = new Size(300, 50);

Example 3: Implementing Continuous Shadow Blink

This example demonstrates how to continuously blink the drop shadow effect to draw attention to the control.

// Create an instance of the card number box control
SiticoneCardNumberBox cardNumberBox = new SiticoneCardNumberBox();

// Configure the shadow to continuously blink
cardNumberBox.EnableDropShadow = true;
cardNumberBox.ShadowColor = Color.FromArgb(60, 0, 0, 0);
cardNumberBox.ShadowBlur = 10;
cardNumberBox.BlinkShadow = true;
cardNumberBox.ContinuousBlink = true;  // The blink effect will run continuously
cardNumberBox.ShadowAnimationDuration = 150;  // Faster animation for a dynamic effect

// Add the control to the form
this.Controls.Add(cardNumberBox);
cardNumberBox.Location = new Point(20, 180);
cardNumberBox.Size = new Size(300, 50);

Key Points

The table below summarizes the key aspects of the Shadow & Animation Effects feature:

Topic	Description
Drop Shadow Customization	Enable and configure drop shadows with customizable color, blur, and opacity for enhanced depth.
Blink and Animation	Control the blink behavior of the shadow with properties for duration, count, and continuous mode.
Visual Feedback	Use animations to draw user attention during control state changes (e.g., focus or hover).

---

Best Practices

The table below outlines recommended practices for implementing shadow and animation effects:

Best Practice	Explanation
Use subtle shadow effects for a professional look	Overly strong shadows may distract users; choose a semi‑transparent color and moderate blur value.
Adjust animation duration based on context	Ensure that the animation is smooth and not disruptive by testing different durations.
Test blink effects on different backgrounds and themes	Verify that the blinking shadow remains visible without clashing with other UI elements.
Avoid continuous blink in production interfaces unless necessary	Continuous blink effects can be distracting; use them only when drawing attention is critical.

---

Common Pitfalls

The table below lists common pitfalls and ways to avoid them:

Pitfall	How to Avoid It
Overpowering visual effects with too dark a shadow	Use semi‑transparent colors and moderate opacity to prevent the shadow from overwhelming the control.
Inconsistent animation timing	Standardize the ShadowAnimationDuration across similar controls for consistency in the UI.
Distracting continuous blink effects	Reserve continuous blink effects for alerts or notifications, and avoid them in static, professional forms.
Misconfigured blink count	Set BlinkCount appropriately to avoid rapid or insufficient feedback; test with various values.

---

Usage Scenarios

The table below describes several scenarios where shadow and animation effects can enhance the user interface:

Scenario	Description
Focus and hover state indication	Use shadow animations to highlight the control when it gains focus or is hovered over.
Themed user interfaces	Adjust shadow color and blur to match the overall theme (light or dark) of your application.
Dynamic feedback for alerts	Implement blink effects to draw attention to important input fields during error states or notifications.

---

Real Life Usage Scenarios

Scenario	Example
Payment form UI	Use a subtle drop shadow to give depth to the card number input field and blink the shadow when an error occurs.
Mobile banking app	Enhance the user experience by dynamically animating the control's shadow during focus transitions to guide the user.
Desktop dashboards	Apply consistent shadow and animation effects across form controls to maintain a professional and modern look.

Troubleshooting Tips

The table below provides troubleshooting advice for common shadow and animation issues:

Issue	Potential Cause	Recommended Action
Shadow not visible	EnableDropShadow may not be enabled or opacity is set too low.	Ensure EnableDropShadow is set to true and use a semi‑transparent color for ShadowColor.
Animation appears choppy	ShadowAnimationDuration might be too short or too long.	Experiment with different duration values to achieve a smooth transition effect.
Blink effect too distracting	ContinuousBlink or BlinkCount settings may be misconfigured.	Adjust BlinkCount and consider using non‑continuous blink for a less intrusive effect.

            ShadowColor = Color.FromArgb(50, 0, 0, 0),
            ShadowBlur = 10,
            BlinkShadow = true,
            ContinuousBlink = false,
            BlinkCount = 3,
            ShadowAnimationDuration = 200
        };

    }
}
