# Culture and Formatting in WPF Currency TextBox

Value of `CurrencyTextBox` can be formatted in following ways:

* Culture
* NumberFormatInfo
* Dedicated properties (CurrencyGroupSeparator, CurrencyGroupSizes, CurrencyDecimalDigits, CurrencyDecimalSeparator)

## Culture based formatting

The [CurrencyTextBox](https://www.syncfusion.com/wpf-controls/currency-textbox) provides support for globalization by using the [Culture](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.EditorBase.html#Syncfusion_Windows_Shared_EditorBase_Culture) property. The `Culture` property is used to format the decimal separator and group separator of the `CurrencyTextBox` value based on the respective culture.

{% tabs %}
{% highlight xaml %}

<syncfusion:CurrencyTextBox x:Name="currencyTextBox" Height="25" Width="150" Culture="fr-FR" Value="1234567"/>

{% endhighlight %}

{% highlight C# %}

CurrencyTextBox currencyTextBox = new CurrencyTextBox();
currencyTextBox.Width = 100;
currencyTextBox.Height = 25;
currencyTextBox.Value = 1234567;
currencyTextBox.Culture = new CultureInfo("fr-FR");

{% endhighlight %}
{% endtabs %}

By default the US culture uses “,” as the `CurrencyGroupSeparator` "$" as `CurrencySymbol` and "." as the `CurrencyDecimalSeparator` where as the France culture uses “Space” as the `CurrencyGroupSeparator`, "€" as `CurrencySymbol` and "," as the `CurrencyDecimalSeparator`.

## NumberFormatInfo based formatting

The number formatting of `CurrencyTextBox` can be customized by setting [NumberFormat](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.EditorBase.html#Syncfusion_Windows_Shared_EditorBase_NumberFormat) property.

{% tabs %}
{% highlight xaml %}

<syncfusion:CurrencyTextBox x:Name="currencyTextBox" Height="25" Width="150"  Value="1234567">
    <syncfusion:CurrencyTextBox.NumberFormat >
        <numberformat:NumberFormatInfo CurrencyGroupSeparator="/" 
                                       CurrencyDecimalDigits="4" 
                                       CurrencyDecimalSeparator="*" 
                                       CurrencySymbol="$"/>
    </syncfusion:CurrencyTextBox.NumberFormat>
</syncfusion:CurrencyTextBox>

{% endhighlight %}

{% highlight C# %}

CurrencyTextBox currencyTextBox = new CurrencyTextBox();
currencyTextBox.Width = 150;
currencyTextBox.Height = 25;
currencyTextBox.Value = 1234567;
currencyTextBox.NumberFormat = new NumberFormatInfo()
{
    CurrencyGroupSeparator = "/", 
    CurrencyDecimalDigits = 4,     
    CurrencyDecimalSeparator = "*", 
    CurrencySymbol = "$"
};

{% endhighlight %}
{% endtabs %}

The following code illustrate how to set currency group size by using the `NumberFormat` property.

{% tabs %}
{% highlight C# %}

CurrencyTextBox currencyTextBox = new CurrencyTextBox();
currencyTextBox.Width = 150;
currencyTextBox.Height = 25;
currencyTextBox.Value = 123456789;
currencyTextBox.NumberFormat = new NumberFormatInfo()
{
    CurrencySymbol = "&",
    CurrencyDecimalDigits = 4,
    CurrencyGroupSeparator = "/",
    CurrencyDecimalSeparator = "*",

    // Adding the currency group size via NumberFormat property.
    CurrencyGroupSizes = new int[] { 2, 3, 4 }
};

{% endhighlight %}
{% endtabs %}

## Formatting with dedicated properties

The number formatting of `CurrencyTextBox` can also be customized by setting the [CurrencyGroupSeparator](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyGroupSeparator), [CurrencyGroupSizes](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyGroupSizes), [CurrencyDecimalDigits](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyDecimalDigits) and [CurrencyDecimalSeparator](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyDecimalSeparator), [CurrencySymbol](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencySymbol), [CurrencyNegativePattern](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyNegativePattern), and [CurrencyPositivePattern](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyPositivePattern) properties of CurrencyTextBox. You can show the group separator by enable the [GroupSeperatorEnabled](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_GroupSeperatorEnabled) property to `true`. 

The following code illustrate how to format using the `CurrencyDecimalSeparator`, `CurrencyDecimalDigits`, `CurrencyGroupSeparator`, `CurrencyGroupSizes` property of the `CurrencyTextBox`.

{% tabs %}
{% highlight C# %}

CurrencyTextBox currencyTextBox = new CurrencyTextBox();
currencyTextBox.Width = 150;
currencyTextBox.Height = 25;
currencyTextBox.Value = 123456789;
currencyTextBox.CurrencySymbol = "#";
currencyTextBox.CurrencyDecimalDigits = 4;
currencyTextBox.GroupSeperatorEnabled = true;
currencyTextBox.CurrencyGroupSeparator = "/";
currencyTextBox.CurrencyDecimalSeparator = "*";

// Adding the currency group size via CurrencyGroupSizes property.
currencyTextBox.CurrencyGroupSizes = new Int32Collection() { 4, 3, 2 };

{% endhighlight %}
{% endtabs %}

N> When you use both the `NumberFormat` and the dedicated properties (`CurrencyGroupSeparator`, `CurrencySymbol`, `CurrencyDecimalDigits`, `CurrencyDecimalSeparator` and `CurrencyGroupSizes`) to format the value of `CurrencyTextBox`, the `CurrencyGroupSeparator`and `CurrencyGroupSizes` properties have higher priority.

N> When you use both `NumberFormat` and  `Culture`, the `NumberFormat` will have a higher priority.

### Positive Value Pattern

You can use the [CurrencyPositivePattern](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyPositivePattern) property to customize the location of the currency symbol and the positive currency values. In the table below,"$" denotes the symbol of the currency, and "n" denotes the number.

###  Negative Value Pattern

You can use the [CurrencyNegativePattern](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Shared.CurrencyTextBox.html#Syncfusion_Windows_Shared_CurrencyTextBox_CurrencyNegativePattern) property to customize the location of the currency symbol and the negative currency values. In the table below,"$" denotes the symbol of the currency, and "n" denotes the number.
