<!--- [](https://ci.appveyor.com/project/Dirkster99/NumericUpDownLib) --> [](https://github.com/Dirkster99/NumericUpDownLib/releases/latest) [](http://nuget.org/packages/Dirkster.NumericUpDownLib)   # Overview This library implements numeric up down WPF controls to edit a value: - by dragging the mouse vertically/horizontally (see recording below) or - by clicking up/down arrow (repeat) buttons or - up/down or left right cursor keys or - spinning mousewheel up down on mouseover or - editing a textbox Each control implementation is specific for a certain .Net data type: | Data Type | Control | | :--- | :--- | | byte | ByteUpDown control| | decimal | DecimalUpDown control| | double | DoubleUpDown control| | float | FloatUpDown control| | integer | IntegerUpDown control| | long | LongUpDown control| | sbyte | SbyteUpDown control| | short | ShortUpDown control| | ushort | UshortUpDown control| | uint | UintUpDown control| | ulong | UlongUpDown control| Percentages can be edit at [0-100] while backend viewmodels handles [0-1] values, see FactorToDoubleConverter and PercentageUpDownDemo in demo clients at project site. Controls are fully themeable. Project site contains demos for: - Dark/Light theme and - Generics theme test clients. More Features: - Small Increments and Decrements can be configured to be 1 or any greater value than 1. - Large Small Increments and Decrements can be configured to be 10 or any other value greater 1. - The width of the control can be configured to be fixed (textbox will scroll inside when text is too large) - Up/Down button is disabled when min or max limit is already reached - Up/Down button can be configured to be invisible - Mouse drag mode for editing value can be enabled/disabled - SelectAll on GotFocus of TextBox - IsReadOnly property disables the textbox portion but leaves all other funtions for Increment/Decrement available # LargeStepSize and StepSize There are mouse and keyboard input methods that support 2 different configurable increment/decrement values. ## Mouse Drag Mode The user can hover the mouse over the textbox portion of the control and: - left click/drag vertically or - left click/drag horizontally to change the current value with the size configured in *StepSize* or *LargeStepSize* dependency property. ## Mouse Wheel The user can hover the mouse over the textbox portion and spin the mouse wheel with: - no modifier key pressed or - a modifier key pressed to change the current value with the size configured in *StepSize* or *LargeStepSize* dependency property. The modifier key for changing the value with *LargeStepSize* can be configured in the *MouseWheelAccelaratorKey* dependency property. ## Cursor Keys The user can click into the textbox portion of the control and: - press cursor left or right or - press cursor up and down to change the current value with the size configured in *StepSize* or *LargeStepSize* dependency property. # Demo Applications There is a demo application that shows the usage of the control (Light/Black themes enabled) and documents the features, such as, the ability to configure a minimum and maximum value that can be used to keep the resulting value within a given bound.     ## Theming Load *Light* or *Dark* brush resources in you resource dictionary to take advantage of existing definitions. ```XAML <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/NumericUpDownLib;component/Themes/DarkBrushs.xaml" /> </ResourceDictionary.MergedDictionaries> ``` ```XAML <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/NumericUpDownLib;component/Themes/LightBrushs.xaml" /> </ResourceDictionary.MergedDictionaries> ``` These definitions do not theme all controls used within this library. You should use a standard theming library, such as: - [MahApps.Metro](https://github.com/MahApps/MahApps.Metro), - [MLib](https://github.com/Dirkster99/MLib), or - [MUI](https://github.com/firstfloorsoftware/mui) to also theme standard elements, such as, button and textblock etc. Visit the project's [Wiki](https://github.com/Dirkster99/NumericUpDownLib/wiki) for mode details.
