"C0"(currency without decimals)"D""Dx", where x is the number of zero-padded digits (e.g.,"D3")"G""N0""X"(uppercase hexadecimal)"x"(lowercase hexadecimal)
Basic custom numeric formats are also supported, such as:
"0' days'"
Minimum and Maximum Values
Minimum and maximum values may be assigned via the Maximum and Minimum properties.
No values can be committed that lay outside of the inclusive range created by those properties.
Parts and Incrementing/Decrementing
This edit box has a single part.
When the caret is over a part, the part value may be incremented or decremented. Please see the Edit Box Basics topic for information on how to do this.
Small value changes alter the current number component by 1, which is the default for the SmallChange property. Large value changes alter the current number component by 5, which is the default for the LargeChange property.
The DefaultValue property sets the value that will be set when incrementing or decrementing from a null value.
Built-in Picker Kinds
This edit box has multiple built-in picker kinds that can be set via the Int32EditBox.PickerKind property, which is of type Int32EditBoxPickerKind.
The default value in WPF is Calculator.
The Default picker kind renders using a radial slider, while the Calculator picker kind utilizes the Calculator control.
Sample XAML
This control can be placed within any other XAML container control, such as a Page or Panel with this sort of XAML:
