Corner and Shape Customization

Allows developers to modify the roundness of each corner of the button control, enabling tailored visual aesthetics that can range from sharp-edged designs to fully rounded buttons.

Overview

The Corner and Shape Customization feature provides granular control over the button's geometry by letting developers specify individual corner radii through properties such as CornerRadiusTopLeft, CornerRadiusTopRight, CornerRadiusBottomLeft, and CornerRadiusBottomRight. This flexibility helps achieve a wide range of design styles, from modern minimalistic interfaces with subtle curves to highly stylized controls with pronounced rounded corners. Changes to these properties trigger immediate visual updates, ensuring that the control’s shape integrates seamlessly with the overall application design.

Properties and Configuration

The table below summarizes the key properties related to Corner and Shape Customization:

Property Name	Description	Default Value / Range	Sample Usage Example
CornerRadiusTopLeft	Specifies the radius of the top-left corner, controlling its roundness.	Integer (default is 0, must be ≥ 0)	myButton.CornerRadiusTopLeft = 10;
CornerRadiusTopRight	Specifies the radius of the top-right corner, controlling its roundness.	Integer (default is 0, must be ≥ 0)	myButton.CornerRadiusTopRight = 10;
CornerRadiusBottomLeft	Specifies the radius of the bottom-left corner, controlling its roundness.	Integer (default is 0, must be ≥ 0)	myButton.CornerRadiusBottomLeft = 10;
CornerRadiusBottomRight	Specifies the radius of the bottom-right corner, controlling its roundness.	Integer (default is 0, must be ≥ 0)	myButton.CornerRadiusBottomRight = 10;

Note: The effective shape of the button is recalculated whenever these properties are updated, ensuring that the control is redrawn with the new corner specifications.

Key Points

Key Point	Details
Customizable Corners	Each corner can be individually adjusted to create a unique control shape that fits your design needs.
Immediate Visual Feedback	Changes to the corner radii properties trigger a re-layout and redraw, providing real-time updates to the control's appearance.
Versatile Design Possibilities	From sharp rectangular edges (all zeros) to fully rounded buttons (radius equals half the button’s height), the options are extensive.

Best Practices

Best Practice	Description	Example Code Snippet
Maintain Consistency Across Controls	Use consistent corner radius values across similar controls to achieve a unified look throughout your application.	csharp<br>myButton.CornerRadiusTopLeft = 8;<br>myButton.CornerRadiusTopRight = 8;<br>myButton.CornerRadiusBottomLeft = 8;<br>myButton.CornerRadiusBottomRight = 8;<br>
Use Subtle Rounding for Professional Look	For most business applications, subtle curves (e.g., 4 to 8 pixels) create a modern, refined appearance without being overly dramatic.	csharp<br>myButton.CornerRadiusTopLeft = 6;<br>myButton.CornerRadiusTopRight = 6;<br>
Experiment with Asymmetrical Radii	To create unique visual effects or highlight certain controls, try using different radii for each corner.	csharp<br>myButton.CornerRadiusTopLeft = 10;<br>myButton.CornerRadiusTopRight = 5;<br>myButton.CornerRadiusBottomLeft = 5;<br>myButton.CornerRadiusBottomRight = 10;<br>

Common Pitfalls

Pitfall	Description	How to Avoid
Over-Rounding	Setting very high corner radii can cause the control to lose its rectangular structure and may lead to undesirable visual artifacts.	Test different values to ensure that the rounded corners do not compromise the button's usability.
Inconsistent Appearance Across Controls	Using drastically different corner radii on similar controls can create a disjointed user interface.	Standardize on a set of corner radius values for similar controls to maintain design consistency.
Ignoring Content Layout Adjustments	Overly rounded corners may affect the internal layout and padding calculations, potentially misaligning the text.	Validate that the text remains legible and well-positioned after adjusting corner radii.

Usage Scenarios

Scenario	Description	Sample Integration Code
Modern Button Designs	Create buttons with soft, rounded edges for a sleek and modern look suitable for contemporary user interfaces.	csharp<br>myButton.CornerRadiusTopLeft = 10;<br>myButton.CornerRadiusTopRight = 10;<br>myButton.CornerRadiusBottomLeft = 10;<br>myButton.CornerRadiusBottomRight = 10;<br>
Emphasized or Highlighted Controls	Use asymmetrical rounding to draw attention to specific buttons, such as primary call-to-action controls.	csharp<br>primaryButton.CornerRadiusTopLeft = 15;<br>primaryButton.CornerRadiusTopRight = 15;<br>primaryButton.CornerRadiusBottomLeft = 5;<br>primaryButton.CornerRadiusBottomRight = 5;<br>
Adaptive Design for Various Themes	Adjust corner radii dynamically based on the application theme or user preferences to create a more personalized UI.	csharp<br>if(theme == "modern") {<br> myButton.CornerRadiusTopLeft = 8;<br> myButton.CornerRadiusTopRight = 8;<br>} else {<br> myButton.CornerRadiusTopLeft = 0;<br> myButton.CornerRadiusTopRight = 0;<br>}<br>

---

Real Life Usage Scenarios

Real Life Scenario	Description	Example Implementation
Enterprise Software UI	In professional applications, subtle rounded corners can provide a modern, less harsh interface without compromising functionality.	csharp<br>enterpriseButton.CornerRadiusTopLeft = 6;<br>enterpriseButton.CornerRadiusTopRight = 6;<br>enterpriseButton.CornerRadiusBottomLeft = 6;<br>enterpriseButton.CornerRadiusBottomRight = 6;<br>
Consumer-Focused Mobile-Style Applications	For applications designed with a mobile-first approach, more pronounced rounded corners can contribute to a friendly, approachable design.	csharp<br>mobileButton.CornerRadiusTopLeft = 12;<br>mobileButton.CornerRadiusTopRight = 12;<br>mobileButton.CornerRadiusBottomLeft = 12;<br>mobileButton.CornerRadiusBottomRight = 12;<br>

Troubleshooting Tips

Issue	Potential Cause	Resolution
Rounded Corners Not Appearing	The properties may not be properly assigned, or the control may not be redrawn after changing corner values.	Ensure the properties are set correctly and call Invalidate() if necessary to force a redraw of the control.
Text or Icon Clipping	Excessive rounding can sometimes cause the content inside the button to be misaligned or clipped.	Adjust the TextPadding and verify the control's internal layout after modifying the corner radii.
Inconsistent Appearance Across Resolutions	Different screen resolutions may render rounded corners with slight variances if not tested thoroughly.	Test the control on multiple devices and resolutions to ensure consistent appearance and behavior.

Integration Code Sample

The following example demonstrates how to integrate Corner and Shape Customization into a simple WinForms application:

using System;
using System.Drawing;
using System.Windows.Forms;
using SiticoneNetFrameworkUI; // Ensure the correct namespace is referenced

public class MainForm : Form
{
    public MainForm()
    {
        // Initialize and configure a SiticoneGroupButton with custom corner radii
        SiticoneGroupButton customShapeButton = new SiticoneGroupButton
        {
            Text = "Rounded Button",
            Size = new Size(220, 50),
            Location = new Point(20, 20),
            // Set individual corner radii for a fully rounded look
            CornerRadiusTopLeft = 15,
            CornerRadiusTopRight = 15,
            CornerRadiusBottomLeft = 15,
            CornerRadiusBottomRight = 15,
            // Other visual properties can be set as desired
            NormalColor = Color.FromArgb(100, 100, 100),
            HoverColor = Color.FromArgb(80, 80, 80),
            PressColor = Color.FromArgb(50, 50, 50),
            TextColor = Color.LightGray,
            SelectedTextColor = Color.White
        };

        // Add the button to the form
        Controls.Add(customShapeButton);
    }

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new MainForm());
    }
}

Frequently Asked Questions (FAQ)

Question	Answer
How do I set a fully rounded button?	Set all four corner properties to a value that is half of the button’s height (or greater), for example: myButton.CornerRadiusTopLeft = 25; and so on.
Can I have asymmetrical corners?	Yes, each corner radius property can be set independently to create asymmetrical or unique shapes.
Will changing corner radii affect the text layout?	The control automatically recalculates the layout based on corner adjustments; however, ensure that TextPadding is configured appropriately to prevent clipping.
