DxMaskedInput<T>.Mask Property

Specifies a mask pattern.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v22.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public string Mask { get; set; }

Property Value

Type	Description
String	A mask pattern string.

Remarks

Use the Mask property to set up a Masked Input‘s mask pattern in code.

Mask Types

The Masked Input component supports four mask types:

• Date-time
• Numeric
• Text
• Regular Expression

Apply a Mask

To set up a mask, assign a desired mask pattern to the Mask property.

<DxMaskedInput @bind-Value="Value"
               Mask="[phone]" >
</DxMaskedInput>

@code{
    String Value { get; set; }
}

You should also set the MaskMode property to MaskMode.RegEx to enable a Regular Expression mask.

<DxMaskedInput @bind-Value="Value"
               Mask="[A-Z]*"
               MaskMode="@MaskMode.RegEx" />

@code{
    String Value { get; set; }
}

Configure Mask Properties

If required, configure mask settings (the current culture, placeholder characters, and so on). For this purpose, add the component that corresponds to the mask type (DxDateTimeMaskProperties, DxNumericMaskProperties, DxTextMaskProperties, and DxRegExMaskProperties) to the Masked Input markup and specify the component’s properties.

The code below enables the French culture and changes the default mask placeholder (_) to the custom character (#).

@using System.Globalization

<DxMaskedInput @bind-Value="Value"
               Mask="[A-Z]{3}-[0-9]{2}"
               MaskMode="@MaskMode.RegEx">
    <DxRegExMaskProperties Culture="Culture" Placeholder="Placeholder" />
</DxMaskedInput>

@code{
    String Value { get; set; }
    char Placeholder = '#';
    CultureInfo Culture = CultureInfo.GetCultureInfo("fr-FR");
}
