DxMaskedInputSettings.MaskMode Property

Specifies a mask mode.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(MaskMode.Auto)]
[Parameter]
public MaskMode MaskMode { get; set; }

Property Value

Type	Default	Description
MaskMode	Auto	An enumeration value.

Available values:

Name	Description
Auto	The component activates a mask type based on the Value data type.
Numeric	The component activates the Numeric mask type.
DateTime	The component activates the Date-time mask type.
RegEx	The component activates the Regular Expression mask type.
Text	The component activates the Text mask type.
DateTimeOffset	The component activates the Date-time Offset mask type.
TimeSpan	The component activates the Time Span mask type.
DateOnly	The component activates the DateOnly mask type.
TimeOnly	The component activates the TimeOnly mask type.

Remarks

The masked input editor activates a mask type based on the column data type. For instance, if you bind the column to a DateTime object, the editor activates the date-time mask type.

The component cannot automatically activate the regular expression mask type because no data type corresponds to this mask type. Set the MaskMode property to RegEx to manually activate the regular expression mask type.

Employee.cs

public class Employee {
    public int ID { get; set; }
    public string? FirstName { get; set; }
    public string? LastName { get; set; }
    public DateTime? BirthDate { get; set; }
    public DateTime? HireDate { get; set; }
    public string? Email { get; set; }
}

The masked input can convert strings that store data source objects to compatible data types. For instance, the component can convert the “11/09/2022” string to DateTime and DateTimeOffset objects. Use the MaskMode property to manually activate a mask type and convert the string to the corresponding data type.

Refer to the following section for more information: Apply a Mask.

To change the mask mode at runtime, use the IMaskedInputSettings.MaskMode property instead.
