Progress Value Management

Progress Value Management provides mechanisms to set, update, and retrieve the progress value with a defined range and percentage display.

Overview

The Progress Value Management feature in the SiticoneHBarsProgress component allows developers to control and monitor the current progress through properties, events, and utility methods. This feature encompasses setting the progress value, enforcing a valid range via the Minimum and Maximum properties, providing percentage calculations, and offering both animated and immediate updates. The following documentation details its API, usage examples, key points, best practices, common pitfalls, and more.

API Reference

Feature Element	Type	Default Value	Description
Value	Property (double)	65 (target value)	Gets or sets the target progress value; when set, the component animates (if enabled) to this new value within the defined range.
Minimum	Property (double)	0	Defines the minimum allowed progress value.
Maximum	Property (double)	100	Defines the maximum allowed progress value; setting a value greater than Maximum or less than Minimum is automatically adjusted.
Percentage	Property (int)	Computed percentage	Returns the current progress as a percentage of the range defined by Minimum and Maximum.
ProgressChanged	Event	N/A	Fired whenever the progress value changes; provides both the old and new progress values via a custom event argument.
ResetValue()	Method	N/A	Resets the progress value to the Minimum value immediately.
SetValueWithoutAnimation()	Method (double)	N/A	Sets the progress value instantly, bypassing any animation logic.
IncrementValue()	Method (double)	1 (default increment)	Increases the current progress value by a specified amount without exceeding Maximum.
DecrementValue()	Method (double)	1 (default decrement)	Decreases the current progress value by a specified amount without going below Minimum.
GetValueAtPosition()	Method (Point)	N/A	Returns the corresponding progress value for a given point (x-coordinate) on the control, taking padding and width into account.
GetPositionFromValue()	Method (double)	N/A	Calculates and returns the x-coordinate (as a Point) corresponding to a specified progress value based on the control's dimensions and current range settings.

Code Examples

Example 1: Setting and Updating the Progress Value

This example demonstrates how to configure the progress value, enforce valid ranges, and handle progress changes via events.

// Instantiate the progress bar control.
var progressBar = new SiticoneHBarsProgress();

// Set initial progress value to 30.
progressBar.Value = 30;

// Subscribe to the ProgressChanged event.
progressBar.ProgressChanged += (sender, e) =>
{
    Console.WriteLine($"Progress changed from {e.OldValue} to {e.NewValue} (Difference: {e.ProgressDifference})");
};

// Update the progress value (animated if AnimationEnabled is true).
progressBar.Value = 75;

// Output the current percentage.
Console.WriteLine($"Current Percentage: {progressBar.Percentage}%");

Example 2: Immediate Value Update Without Animation

This sample shows how to set the progress value instantly without triggering the animation.

// Set progress value immediately to 50, bypassing the animation.
progressBar.SetValueWithoutAnimation(50);

// Verify update through percentage display.
MessageBox.Show($"Progress is now at {progressBar.Percentage}%");

Example 3: Incrementing and Decrementing Progress

Demonstrates how to adjust the progress value incrementally, ensuring it remains within the defined range.

// Increment the progress value by 10.
progressBar.IncrementValue(10);
Console.WriteLine($"Progress incremented: {progressBar.Value}");

// Decrement the progress value by 5.
progressBar.DecrementValue(5);
Console.WriteLine($"Progress decremented: {progressBar.Value}");

Example 4: Mapping Positions to Progress Values

Illustrates how to convert between a graphical position and a progress value, useful for interactive controls.

// Simulate a mouse click at a specific position on the control.
Point mousePosition = new Point(150, 7);

// Retrieve the progress value corresponding to this position.
double valueAtPosition = progressBar.GetValueAtPosition(mousePosition);
Console.WriteLine($"Progress value at position {mousePosition.X}: {valueAtPosition}");

// Determine the x-coordinate for a given progress value.
Point positionFromValue = progressBar.GetPositionFromValue(80);
Console.WriteLine($"Position corresponding to progress value 80: {positionFromValue.X}");

Key Points

Aspect	Details
Range Enforcement	The Minimum and Maximum properties ensure that progress values remain within a specified range, automatically adjusting values when necessary.
Animated vs. Immediate	The control supports both animated updates via the Value property and immediate updates via SetValueWithoutAnimation, catering to various UI responsiveness needs.
Percentage Calculation	The Percentage property computes the current progress based on the defined range, providing an intuitive display value for users.
Utility Methods	Methods like IncrementValue, DecrementValue, GetValueAtPosition, and GetPositionFromValue simplify interactive and programmatic adjustments.

Best Practices

Practice	Description
Validate Range Settings	Always set meaningful Minimum and Maximum values to prevent unexpected behavior when updating the progress value.
Use Immediate Updates When Needed	Use SetValueWithoutAnimation for critical UI updates that must be reflected instantly, bypassing the standard animation for rapid feedback.
Handle Progress Events	Subscribe to the ProgressChanged event to synchronize other UI elements or trigger additional logic when the progress value changes.
Ensure Consistent Increments	When using IncrementValue or DecrementValue, consider the overall range to maintain consistent and predictable progress adjustments.

---

Common Pitfalls

Pitfall	Cause/Resolution
Value Outside of Range	Setting a progress value below Minimum or above Maximum will automatically adjust the value; ensure that your logic accounts for these constraints to avoid confusion.
Inconsistent UI Updates	Failing to update UI elements that rely on the Percentage property when the progress value changes can lead to mismatches; always subscribe to progress change events.
Over-Reliance on Animation	Excessive reliance on animated transitions may delay critical updates; consider using immediate updates when real-time feedback is required.
Ignoring Utility Methods	Overlooking methods like GetValueAtPosition and GetPositionFromValue may complicate interactive scenarios; leverage these utilities to maintain code clarity and accuracy.

Usage Scenarios

Scenario	Implementation Details
File Upload Progress	Set the progress value dynamically based on the number of bytes uploaded, and use the Percentage property to display the upload status to the user.
Data Processing Indicators	As data is processed, update the progress value to reflect progress and trigger additional UI elements via the ProgressChanged event, ensuring the user is informed.
User-Interactive Controls	When users adjust a slider or click on the control, use GetValueAtPosition to determine the new progress value and update the control accordingly.
Step-by-Step Workflows	In wizard-style interfaces, increment or decrement the progress value to visually guide users through a series of steps, ensuring consistency with Minimum and Maximum settings.
