Text and Placeholder Config.
Text and Placeholder Management provides extensive control over text input, transformation, and placeholder display.
Overview
This section documents the properties and behaviors related to managing the text content, placeholder text, alignment, case transformations, and text formatting within the control. Developers can customize how text is displayed, edited, and transformed to meet application requirements.
Key Points
Text Content
Controls the actual text displayed in the control and supports dynamic updates with events to track changes.
Placeholder Handling
Manages the display of placeholder text when no user input is present, including its text, color, and fade animation behavior.
Text Alignment & Layout
Offers options to align text horizontally (left, center, right) and control internal padding for proper layout.
Text Transformation
Supports automatic transformation of text to upper, lower, or normal case via the TextCaseMode property.
Font Styling
Provides toggles for bold, italic, underline, and strike-through formatting to emphasize or modify the visual style of the text.
Best Practices
Consistent Input Design
Use consistent text formatting and placeholder styles across controls for a uniform user experience.
Clarity in Placeholder
Ensure that the placeholder text is clear and contrasts well with the background so that it is easily distinguishable when the control is empty.
Appropriate Transformations
Choose the appropriate TextCaseMode to match the desired user experience; for example, enforcing uppercase for specific types of input.
Use Formatting Sparingly
Apply bold, italic, underline, and strike-through formatting only when necessary to avoid visual clutter.
Common Pitfalls
Misleading Placeholder
A placeholder that is too similar in color or font style to the actual text can confuse users about whether input has been entered.
Overuse of Text Formatting
Excessive use of font styling (e.g., bold, italic, underline) may reduce readability and lead to a cluttered interface.
Incorrect Text Alignment
Setting text alignment or padding improperly may result in misaligned or truncated text, especially when the control is resized.
Inconsistent Case Handling
Failing to apply text case transformations consistently can result in unexpected behavior when comparing or processing input text.
Real Life Usage Scenarios
Data Entry Forms
Use placeholder text to guide users in entering information and apply text case transformations to ensure consistency (e.g., converting to uppercase).
Search Boxes
Implement clear placeholder text and text alignment to enhance usability and provide immediate feedback as users type.
Customizable Input Fields
Enable formatting options (bold, italic, underline) to allow users to emphasize parts of their input when needed, such as in rich text editors.
Validation-Driven Interfaces
Combine text management with input validation to ensure that the text meets specific criteria before processing or storing it.
Troubleshooting Tips
Placeholder Not Fading Properly
Check that the PlaceholderFadeInterval
and PlaceholderFadeStep
properties are set to appropriate values and that the control’s text is empty.
Text Not Transforming Correctly
Verify that the TextCaseMode
property is configured properly (Normal, Upper, or Lower) and that any external text modifications are not conflicting.
Misaligned Text or Placeholder
Adjust the TextPadding
and review the TextAlign
settings to ensure the content is positioned correctly within the control's boundaries.
Inconsistent Font Formatting
Confirm that the properties for IsBold
, IsItalic
, IsUnderline
, and IsStrikeThrough
are updated and applied consistently when text changes.
Property Reference
Below is a reference table of key properties for text and placeholder management:
Text
string
The primary text content of the control; setting this property updates the display and triggers events.
PlaceholderText
string
The text displayed when the control is empty, providing guidance for the expected input.
PlaceholderColor
Color
The color applied to the placeholder text, which can be animated using the fade settings.
TextAlign
TextAlignment
Specifies the horizontal alignment of the text (Left, Center, or Right).
MaxLength
int
The maximum number of characters allowed in the text content.
TextCaseMode
TextCase
Determines whether the text is displayed in normal, upper, or lower case.
IsBold, IsItalic, IsUnderline, IsStrikeThrough
bool
Toggles for applying specific font styles to the text content.
TextPadding
Padding
Defines the internal spacing between the text and the control’s boundaries.
PlaceholderFadeInterval
int
The interval (in milliseconds) between steps in the placeholder fade animation.
PlaceholderFadeStep
double
The incremental step size used in the placeholder fade animation to control the smoothness of the transition.
Code Examples
Below are several code examples that demonstrate how to use the Text & Placeholder Management properties.
Example 1: Basic Text and Placeholder Configuration
This example shows how to set basic text properties and configure placeholder text, color, and alignment.
Example 2: Dynamic Text Transformation and Formatting
This example demonstrates updating text formatting properties (case transformation and font styles) at runtime.
Example 3: Combining Text Transformation with Placeholder Animation
This example demonstrates the interplay between text transformations, placeholder behavior, and fade animations.
Frequently Asked Questions
How do I switch between gradient and solid borders?
Set the UseBorderGradient
property to true for gradients or false for a solid border, and adjust the respective color properties accordingly.
Can I animate the appearance changes?
Yes, properties such as shadow opacity and border color transitions are animated via internal timers; ensure that animation duration properties (like ShadowAnimationDuration
) are set appropriately.
What should I do if my text appears misaligned?
Adjust the TextPadding
property to ensure that the text is centered and spaced correctly within the control.
How can I improve performance if animations are too heavy?
Consider reducing the animation durations or disabling certain animated effects such as shadow blinking if performance becomes an issue.
Is it possible to change the corner radii at runtime?
Yes, the corner radius properties (CornerRadiusTopLeft
, etc.) can be updated at runtime to change the shape of the control dynamically.
How do I ensure my control adheres to the overall application theme?
Use the gradient and color properties in combination with dynamic state changes (such as focus and hover events) to match your application's design standards.
What is the recommended approach for responsive design?
Use relative padding and dynamic adjustments of corner radii and border sizes to ensure that the control scales well across different resolutions and sizes.
How can I verify that state-specific styling (hover/focus) is working?
Test the control by simulating hover and focus events in your application and observe the changes in border color or gradient transitions as defined by the properties.
Integration Checklist
Border and Fill Configuration
Confirm that properties such as ShowBorder
, BorderSize
, SolidBorderColor
, FillColor1
, and FillColor2
are correctly set.
Gradient Setup
Verify that UseBorderGradient
and UseFillGradient
are enabled when needed and that gradient colors and modes are defined correctly.
Shadow and Corner Settings
Ensure that EnableDropShadow
, ShadowBlur
, and corner radius properties meet the desired design specifications.
Text Padding and Layout
Adjust the TextPadding
values to guarantee that text is properly aligned and spaced within the control.
Runtime Behavior
Test dynamic changes by updating properties at runtime and observing their effects on hover, focus, and read-only states.
System Theme Integration (if used)
Check that dynamic theme changes (if using TrackSystemTheme
) update the control’s appearance consistently with the system settings.
Event Handling Verification
Ensure that any changes trigger the appropriate events (e.g., focus changes, theme changes) and that visual feedback is provided as expected.
Accessibility Compliance
Verify that color choices and text alignments meet accessibility standards for contrast and readability.
Cross-Platform Consistency
Confirm that the control renders consistently across different versions of Windows and with various DPI settings if applicable.
