Read‑Only Mode
This feature prevents user interactions with the progress bar while still providing clear visual feedback, ensuring that the control can signal a locked state effectively.
Overview
The Read‑Only Mode feature is designed to disable user modifications to the progress bar while still displaying progress updates. In this mode, the control adjusts its visual styling to indicate that interaction is not permitted by switching to alternative colors and feedback mechanisms. Additionally, optional audio (beep) and visual shake effects are provided to alert users when they attempt to interact with a read‑only progress bar.
Properties and Their Details
IsReadonly
Enables or disables the read‑only state of the control; when true, the progress bar becomes non-interactive.
false
ReadonlyFillColor1
The primary fill color used for the progress bar in read‑only mode, providing a visual cue that the control is inactive.
Gray
ReadonlyFillColor2
The secondary fill color used in gradient fills when the control is in read‑only mode, enhancing visual distinction.
DarkGray
ReadonlyBorderColor
The color used to draw the border of the progress bar when it is in read‑only mode.
DimGray
ReadonlyForeColor
The color of the text (label) in read‑only mode, ensuring that it remains legible against the modified background.
White
CanBeep
Controls whether an audio beep is played when a user attempts to interact with the control while it is in read‑only mode.
true
CanShake
Determines whether a shake animation is triggered upon interaction attempts when the control is read‑only, providing visual feedback.
true
Note: In read‑only mode, all interactive features—such as value dragging—are disabled, ensuring that the progress bar remains solely an indicator of progress.
Key Points
Non-Interactive Feedback
When IsReadonly is enabled, user interactions are blocked, and visual cues (alternative fill and border colors) indicate that the control is locked.
Integrated User Alerts
Optional audio beeps (via CanBeep) and shake animations (via CanShake) alert users to the read‑only state if they attempt to modify the control.
Consistent Visual Styling
The control automatically applies a distinct color scheme in read‑only mode, ensuring that its state is visually communicated across various contexts.
Best Practices
Clearly Indicate Inactivity
Use distinct read‑only colors (ReadonlyFillColor1, ReadonlyFillColor2, ReadonlyBorderColor, ReadonlyForeColor) to clearly signal to users that the control is not interactive.
Use Audio/Visual Feedback Judiciously
Enable CanBeep and CanShake only if the additional user feedback aligns with your application’s UX guidelines, as overuse might become distracting.
Disable Unnecessary Interaction Cues
When setting IsReadonly to true, ensure that interactive cues (e.g., drag handles or focus indicators) are disabled to prevent confusion among users.
Common Pitfalls
Inconsistent Visuals
Failing to update all related read‑only properties (fill, border, and text colors) can result in a confusing or inconsistent appearance.
Update all visual properties consistently when toggling read‑only mode.
Overuse of Feedback Effects
Excessive use of beep or shake feedback may annoy users, particularly if the control is read‑only for extended periods.
Evaluate the necessity of CanBeep and CanShake based on the application’s context and disable if overly intrusive.
Ignoring Accessibility Considerations
In read‑only mode, if the color contrast is insufficient, the label may become hard to read, reducing accessibility.
Test and adjust the ReadonlyForeColor and background fill colors to ensure sufficient contrast for all users.
Usage Scenarios
Disabling User Modifications
In applications where progress should be displayed but not modified (e.g., monitoring task progress), enable read‑only mode to prevent accidental changes.
csharp<br>// Initialize a read‑only progress bar<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.IsReadonly = true;<br>progressBar.Value = 80;<br>this.Controls.Add(progressBar);<br>
Enhanced User Alerts in Read‑Only Mode
When a user attempts to interact with a read‑only control, use audio and shake feedback to indicate that the control is locked.
csharp<br>// Configure read‑only feedback options<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.IsReadonly = true;<br>progressBar.CanBeep = true;<br>progressBar.CanShake = true;<br>this.Controls.Add(progressBar);<br>// User attempts to click will trigger beep and shake feedback (handled internally by the control)<br>
Visual Differentiation in Themed Applications
Adjust the read‑only color scheme to match your application's theme, ensuring that read‑only controls are visually distinct yet harmonious with the overall design.
csharp<br>// Customize read‑only colors to align with a dark theme<br>SiticoneHProgressBar progressBar = new SiticoneHProgressBar();<br>progressBar.IsReadonly = true;<br>progressBar.ReadonlyFillColor1 = Color.FromArgb(80, 80, 80);<br>progressBar.ReadonlyFillColor2 = Color.FromArgb(50, 50, 50);<br>progressBar.ReadonlyBorderColor = Color.Gray;<br>progressBar.ReadonlyForeColor = Color.LightGray;<br>this.Controls.Add(progressBar);<br>
Code Example and Demo
Below is an extensive example demonstrating how to integrate and customize the Read‑Only Mode feature in a simple WinForms application:
Review
User Interaction Prevention
The IsReadonly property effectively disables user input, ensuring that the progress bar remains unmodifiable during critical operations.
Visual Clarity
By switching to dedicated read‑only colors, the control clearly communicates its non-interactive state to users, reducing confusion.
Integrated Feedback
Optional beep and shake feedback enhance user awareness when an attempt is made to interact with a read‑only control, aligning with modern UX practices.
Summary
The Read‑Only Mode feature allows the progress bar to be displayed in a non-interactive state, employing a distinct visual style and optional audio/visual feedback to signal that user modifications are disabled. This ensures that progress indicators remain reliable and consistent in contexts where interaction should be prevented.

Troubleshooting Tips
Validate Color Consistency
Confirm that the read‑only colors (fill, border, and text) are consistently applied across different states to avoid user confusion.
Test Feedback Effects
Ensure that the beep and shake effects do not become disruptive by testing them in the context of your application and adjusting as necessary.
Monitor Control Interactivity
Verify that when IsReadonly is enabled, all interactive features (such as value dragging) are properly disabled to maintain a true read‑only state.
