                          MinValue="0" MaxValue="100" Value="10"
                          ScrollInterval="1" />

Common Patterns

Bind

Value

to a

ViewModel

property and use

UpdateSourceTrigger=PropertyChanged

for immediate updates.

Use
```
MinValidation
```
/
```
MaxValidation
```
to choose between strict-on-keypress and permissive-on-lost-focus behaviors.
For globalization, set
```
Culture
```
or
```
NumberFormat
```
and prefer
```
NumberFormat
```
when exact control is required.
