Quick Start (XAML)

快速入门（XAML）

xaml

<syncfusion:DoubleTextBox x:Name="doubleTextBox" Width="150" Height="25"
                          MinValue="0" MaxValue="100" Value="10"
                          ScrollInterval="1" />

xaml

<syncfusion:DoubleTextBox x:Name="doubleTextBox" Width="150" Height="25"
                          MinValue="0" MaxValue="100" Value="10"
                          ScrollInterval="1" />

Common Patterns

常见模式

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.

将
```
Value
```
绑定到
```
ViewModel
```
属性，并使用
```
UpdateSourceTrigger=PropertyChanged
```
实现即时更新。
使用
```
MinValidation
```
/
```
MaxValidation
```
选择严格按键验证或失去焦点时验证的行为。
对于全球化场景，设置
```
Culture
```
或
```
NumberFormat
```
，当需要精确控制时优先使用
```
NumberFormat
```
。
