Usage

When using the SingleUpDown 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. Use IsReadOnly to determine whether the control is read only. If you would like to get the actual formatted string representation of the value, you can use the Text property.

Applying Format Strings

Default:

     <xctk:SingleUpDown Value="1564.674" />

Floating Point:

     <xctk:SingleUpDown FormatString="F3" Value="1564.674" Increment=".001"  Maximum="200000.599" />

Currency:

     <xctk:SingleUpDown FormatString="C2" Value="1564.674" Increment=".5" Maximum="5000.50" Minimum="50.01" />

Supported Format Strings

Format Specifier	Name
C	Currency
F	Fixed Point
G	General
N	Number
P	Percent

Watermark

You can provide a Watermark to show text in place of a NULL Value.

     <xctk:SingleUpDown Watermark="Enter value" />
