# Implementing DoubleTextBox This skill collects guidance and examples for the Syncfusion WPF `DoubleTextBox` control. Use this skill to find usage patterns, configuration options, and common gotchas when building WPF apps that accept double values. ## When to Use This Skill - When adding or configuring a WPF numeric input bound to doubles - When restricting values using `MinValue` / `MaxValue` - When formatting values for different cultures or customizing group/decimal separators - When enabling step/scroll intervals, spin buttons, or range adorner - When you need examples for XAML or C# usage patterns ## Navigation Guide ### Getting Started 📄 **Read:** [references/getting-started.md](references/getting-started.md) - Installing and adding the control via XAML/C#; basic properties and value binding ### Overview 📄 **Read:** [references/overview.md](references/overview.md) - Short feature list and control summary ### Appearance & Styling 📄 **Read:** [references/appearance-and-styling.md](references/appearance-and-styling.md) - Foreground for positive/negative/zero, background, corner radius, selection brush ### Validation & Restrictions 📄 **Read:** [references/restriction-or-validation.md](references/restriction-or-validation.md) - Min/Max validation modes, decimal digit limits, read-only mode ### Step Interval & Scrolling 📄 **Read:** [references/step-interval.md](references/step-interval.md) - `ScrollInterval`, mouse wheel, click-and-drag, selection-on-focus ### Culture & Number Formatting 📄 **Read:** [references/culture-and-number-formats.md](references/culture-and-number-formats.md) - `Culture`, `NumberFormat`, dedicated formatting properties ### Range Adorner 📄 **Read:** [references/range-adorner.md](references/range-adorner.md) - Visual range indicator based on `MinValue`/`MaxValue` ### Changing Value & Advanced Behavior 📄 **Read:** [references/changing-double-value.md](references/changing-double-value.md) - Paste behavior, spin buttons, null value handling, watermarks ## Quick Start (XAML) ```xaml <syncfusion:DoubleTextBox x:Name="doubleTextBox" Width="150" Height="25" MinValue="0" MaxValue="100" Value="10" ScrollInterval="1" /> ``` ## Common Patterns - Bind `Value` to a `ViewModel` property and use `UpdateSourceTrigger=PropertyChanged` for immediate updates. - Use `MinValidation`/`MaxValidation` to choose between strict-on-keypress and permissive-on-lost-focus behaviors. - For globalization, set `Culture` or `NumberFormat` and prefer `NumberFormat` when exact control is required.
