Culture and Formatting in WPF Percent TextBox

18 Feb 20256 minutes to read

Value of PercentTextBox can be formatted in following ways:

• Culture
• NumberFormatInfo
• Dedicated properties (PercentGroupSeparator, PercentGroupSizes, PercentDecimalDigits, PercentDecimalSeparator)

Culture based formatting

The PercentTextBox provides support for globalization by using the Culture property. The Culture property is used to format the decimal separator and group separator of the PercentTextBox value based on the respective culture.

XAML

<syncfusion:PercentTextBox x:Name="percentTextBox" Height="25" Width="150" 
                           Culture="bs-Latn" PercentValue="1234567"/>

C#

PercentTextBox percentTextBox = new PercentTextBox();
percentTextBox.Width = 150;
percentTextBox.Height = 25;
percentTextBox.PercentValue = 1234567;

//Setting Latin culture for percent textbox.
percentTextBox.Culture = new CultureInfo("bs-Latn");

By default the US culture uses “,” as the PercentGroupSeparator and “.” as the PercentDecimalSeparator where as the Latin culture uses “.” as the PercentGroupSeparator and “,” as the PercentDecimalSeparator.

Default Culture

Latin Culture

NumberFormatInfo based formatting

The number formatting of PercentTextBox can be customized by setting NumberFormat property.

XAML

<syncfusion:PercentTextBox x:Name="percentTextBox" Height="25" Width="150" PercentValue="1234567">
    <syncfusion:PercentTextBox.NumberFormat >
        <numberformat:NumberFormatInfo PercentGroupSeparator="/"
                                       PercentSymbol="%"
                                       PercentDecimalDigits="4" 
                                       PercentDecimalSeparator="*" />
    </syncfusion:PercentTextBox.NumberFormat>
</syncfusion:PercentTextBox>

C#

PercentTextBox percentTextBox = new PercentTextBox();
percentTextBox.Width = 150;
percentTextBox.Height = 25;
percentTextBox.PercentValue = 1234567;
percentTextBox.NumberFormat = new NumberFormatInfo()
{
    PercentGroupSeparator = "/",
    PercentDecimalDigits = 4,
    PercentDecimalSeparator = "*",
    PercentSymbol = "%"
};

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

C#

PercentTextBox percentTextBox = new PercentTextBox();
percentTextBox.Width = 150;
percentTextBox.Height = 25;
percentTextBox.PercentValue = 123456789;           
percentTextBox.NumberFormat = new NumberFormatInfo()
{
    PercentGroupSeparator = "/",
    PercentDecimalDigits = 4,
    PercentDecimalSeparator = "*",
    PercentSymbol = "%",

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

Formatting with dedicated properties

The number formatting of PercentTextBox can also be customized by setting the PercentGroupSeparator, PercentGroupSizes, PercentDecimalDigits, PercentDecimalSeparator, PercentNegativePattern, PercentPositivePattern, and PercentageSymbol properties of PercentTextBox. You can show the group separator by setting the GroupSeperatorEnabled property to true.

The following code illustrate how to format using the PercentDecimalSeparator, PercentDecimalDigits, PercentGroupSeparator, PercentGroupSizes property of the PercentTextBox.

C#

PercentTextBox percentTextBox = new PercentTextBox();
percentTextBox.Width = 150;
percentTextBox.Height = 25;
percentTextBox.PercentValue = 123456789;
percentTextBox.GroupSeperatorEnabled = true;
percentTextBox.PercentageSymbol = "%";
percentTextBox.PercentDecimalDigits = 4;
percentTextBox.PercentDecimalSeparator = "/";
percentTextBox.PercentGroupSeparator = "*";

// Adding the percent group size via NumberGroupSizes property.
percentTextBox.PercentGroupSizes = new Int32Collection() { 4, 3, 2};

NOTE

When you use both the NumberFormat and the dedicated properties (PercentGroupSeparator, PercentageSymbol, PercentDecimalDigits, PercentDecimalSeparator and PercentGroupSizes) to format the value of PercentTextBox, the PercentGroupSeparatorand PercentGroupSizes properties have higher priority.

NOTE

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

Positive Value Pattern

You can use the PercentPositivePattern property to customize the location of the percent symbol and the positive percent values. In the table below,”%” denotes the symbol of the percent, and “n” denotes the number.

PercentPositivePattern table

Value	Associated Pattern
0	n %
1	n%
2	%n
3	% n

XAML

<syncfusion:PercentTextBox x:Name="percentTextBox" Height="25" Width="150" 
            PercentValue="1234" PercentPositivePattern="3"/>

C#

PercentTextBox percentTextBox = new PercentTextBox();
percentTextBox.Width = 150;
percentTextBox.Height = 25;
percentTextBox.Value = 1234;
percentTextBox.PercentPositivePattern = 3;

Negative Value Pattern

You can use the PercentNegativePattern property to customize the location of the percent symbol and the negative percent values. In the table below,”%” denotes the symbol of the percent, and “n” denotes the number.

PercentNegativePattern table

Value	Associated Pattern
0	-n %
1	-n%
2	-%n
3	%-n
4	%n-
5	n-%
6	n%-
7	-% n
8	n %-
9	% n-
10	% -n
11	n- %

XAML

<syncfusion:PercentTextBox x:Name="percentTextBox" Height="25" Width="150" 
            PercentValue="1234" PercentNegativePattern="7"/>

C#

PercentTextBox percentTextBox = new PercentTextBox();
percentTextBox.Width = 150;
percentTextBox.Height = 25;
percentTextBox.PercentValue = 1234;
percentTextBox.PercentNegativePattern = 7;
