Implementing Syncfusion WPF PercentTextBox

When to Use This Skill

Use this skill when the user needs to:

• Implement percentage input controls in WPF applications with value restrictions and formatting
• Configure value validation with minimum/maximum limits and validation timing (OnKeyPress vs OnLostFocus)
• Apply number formatting with culture-specific separators, decimal digits, and group sizes
• Customize appearance with different foreground colors for positive, negative, and zero values
• Enable interactive features like scroll intervals, mouse wheel support, click-and-drag value changes
• Display visual progress using range adorner to show value relative to min/max range
• Bind percentage data from ViewModels with property change notifications
• Handle null values with custom null displays or watermark text
• Implement international formats with culture-based decimal/group separators and percent symbols

The PercentTextBox control restricts input to double values and displays them as percentages with extensive customization options for data binding, validation, formatting, and appearance.
