WPF DecimalUpDown


First Adding Reference to WPF Toolkit Extended Assembly


When using the DecimalUpDown 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


<wpfx:DecimalUpDown Value="1564.6749586" />

Floating Point:

<wpfx:DecimalUpDown FormatString="F3" Value="1564.6749586" Increment=".001"  Maximum="200000.599" />


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

Supported Format Strings

Format Specifier Name
C Currency
F Fixed Point
G General

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

<wpfx:DecimalUpDown Watermark="Enter Decimal" />
