Remarks

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. To get the actual formatted string representation of the value, use the Text property.

FormatString supports the following specifiers: C (currency), F (fixed point), G (general), N (number), and P (percent).

Example

The following example shows how to create a floating-point CalculatorUpDown using FormatString.

XAML

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

The following example shows how to create a currency CalculatorUpDown using FormatString.

XAML

<xctk:CalculatorUpDown FormatString="C2" Value="1564.6749586" Increment=".5" Maximum="5000.50" Minimum="50.01" />

The following example shows how to use the Watermark property.
