CalculatorUpDown

Derives from Xceed.Wpf.Toolkit.DecimalUpDown

The CalculatorUpDown provides a TextBox with button spinners that allow incrementing and decrementing numeric values by using the spinner buttons, keyboard up/down arrows, or mouse wheel. It also provides a Calculator dropdown which allows you to perform mathematical calculations.

• Supported Format Strings

• Properties/Events

When using the CalculatorUpDown in data binding scenarios, bind your object's value to the Value property. You can specify how much to increment the value by setting the Increment property. You can control the minimum and maximum allowed values by setting the Minimum and the Maximum properties. You can also specify if the user can directly edit the values in the text box by setting the IsEditable property. If you would like to get the actual fromatted string representation of the value, you can use the Text property.

Applying FormatStrings

Default:

<xctk:CalculatorUpDown Value="1564.6749586" />

Floating Point:

<xctk:CalculatorUpDown FormatString="F3" Value="1564.6749586" Increment=".001"  Maximum="200000.599" />

Currency:
