## More Features



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

    

        

    

```



```XAML

    

        

    

```



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.
