# Animation & Indeterminate Mode

## Overview

The Animation & Indeterminate Mode feature manages two key aspects of the control's dynamic behavior. In determinate mode, progress changes trigger a smooth, momentum-based animation toward the target value using properties like AnimationDurationMs and AnimationTimerInterval. In indeterminate mode, a marquee effect is activated to visually indicate that processing is underway even when a precise progress value is not available.

### Properties and Their Details

The table below summarizes the main properties related to animations and indeterminate mode:

| Property               | Description                                                                                                                                     | Default Value                       |
| ---------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------- |
| AnimationDurationMs    | Controls the duration (in milliseconds) for smooth, momentum-based transitions when updating the progress value.                                | 300.0                               |
| AnimationTimerInterval | Sets the interval for the animation timer, dictating how frequently the control is updated during an animation.                                 | 15 (milliseconds)                   |
| Indeterminate          | Toggles the indeterminate (marquee) mode; when set to true, the control stops the determinate animation and starts a continuous marquee effect. | false                               |
| IndeterminateBarColor  | Specifies the color used for the progress bar when in indeterminate mode.                                                                       | ColorTranslator.FromHtml("#221e41") |

*Note:* Although the control’s internal implementation uses additional timers (such as the marquee timer) and fields for managing animation momentum, only the properties listed above are intended for direct customization.

### Best Practices

| Practice                                        | Explanation                                                                                                                                            |
| ----------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Choose Appropriate Duration                     | Select an AnimationDurationMs value that balances smoothness with responsiveness, ensuring that the animation feels natural and not sluggish.          |
| Set Timer Intervals Judiciously                 | Use a reasonable AnimationTimerInterval to achieve fluid animation without overloading the UI thread, especially on less powerful hardware.            |
| Use Indeterminate Mode When Progress Is Unknown | Switch to Indeterminate mode for tasks where the completion percentage is unpredictable, ensuring that users are still aware that work is in progress. |
| Synchronize with Other UI Elements              | Ensure that any changes in animation timing or mode transitions do not conflict with other UI animations to maintain a consistent overall experience.  |

### Common Pitfalls

| Pitfall                        | Explanation                                                                                                                  | Avoidance Strategy                                                                                                   |
| ------------------------------ | ---------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- |
| Overly Long Animation Duration | Setting AnimationDurationMs too high may cause delays that make the UI feel unresponsive.                                    | Test and choose a moderate duration that balances smoothness with responsiveness.                                    |
| Too Short Timer Intervals      | Using a very low AnimationTimerInterval can lead to unnecessary CPU usage and potential performance issues.                  | Use a timer interval that provides smooth animation without excessive resource consumption.                          |
| Indeterminate Mode Overuse     | Keeping the control in indeterminate mode when progress values are available can confuse users about task completion status. | Switch to determinate mode as soon as progress values become available to provide clear feedback on task completion. |

### Usage Scenarios

| Scenario                        | Description                                                                                                                                     | Sample Code Integration                                                                                                                                                                                                                                                                                                                    |
| ------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Task with Known Progress        | When processing tasks with a known completion percentage, use determinate mode to animate progress changes smoothly.                            | `csharp<br>// Initialize a progress bar in determinate mode with animation<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.Indeterminate = false;<br>progressBar.Value = 30;<br>progressBar.AnimationDurationMs = 300;<br>this.Controls.Add(progressBar);<br>`                                            |
| Task with Unknown Progress      | For processes where the progress is unknown (e.g., loading resources or background processing), activate indeterminate mode to show a marquee.  | `csharp<br>// Create a progress bar in indeterminate mode to indicate ongoing processing<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.Indeterminate = true;<br>progressBar.IndeterminateBarColor = Color.Blue;<br>this.Controls.Add(progressBar);<br>`                                                 |
| Dynamic Switching Between Modes | In scenarios where progress initially is unknown and later becomes determinate, dynamically switch between indeterminate and determinate modes. | `csharp<br>// Toggle between indeterminate and determinate mode dynamically<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>// Start with indeterminate mode<br>progressBar.Indeterminate = true;<br>// Later, when progress can be determined:<br>progressBar.Indeterminate = false;<br>progressBar.Value = 75;<br>` |

            updateValueButton.Click += (s, e) =>
            {
                // Increase progress by 10 until maximum is reached
                if (!progressBar.Indeterminate)
                {
                    progressBar.Value = Math.Min(progressBar.Value + 10, progressBar.Maximum);
                }
            };

            // Add controls to the form
            Controls.Add(progressBar);
            Controls.Add(toggleModeButton);
            Controls.Add(updateValueButton);
        }

        private void ToggleModeButton_Click(object sender, EventArgs e)
        {
            // Toggle between indeterminate (marquee) and determinate modes
            isIndeterminate = !isIndeterminate;
            progressBar.Indeterminate = isIndeterminate;

            // Optionally reset or update the progress value when switching modes
            if (!isIndeterminate)
            {
                // Resume determinate mode with a defined progress value
                progressBar.Value = 20;
            }
        }

        [STAThread]

            Application.Run(new MainForm());
        }
    }
}
