V25.1
  • DxTimeSpanMaskProperties.AllowNegativeValue Property

    Specifies whether the editor’s value can be negative.

    Namespace: DevExpress.Blazor

    Assembly: DevExpress.Blazor.v25.1.dll

    NuGet Package: DevExpress.Blazor

    Declaration

    [DefaultValue(true)]
    [Parameter]
    public bool AllowNegativeValue { get; set; }

    Property Value

    Type Default Description
    Boolean true

    true if the editor’s value can be negative; otherwise, false.

    Remarks

    Time span masks allow users to enter a negative time interval. Set this property to false to prevent users from entering a negative value:

    <DxMaskedInput @bind-Value="@time" 
                   Mask="@TimeSpanMask.GeneralShortFormat">
        <DxTimeSpanMaskProperties AllowNegativeValue="false" />
    </DxMaskedInput>
    
    @code {
        TimeSpan time { get; set; } = new TimeSpan(5, 16, 30, 15, 7);
    }
    

    Note

    You can assign a negative value to the editor even if this property is set to false. In this case, the editor converts this value to a positive value only after a user modifies it. Until that time, the editor value remains negative.
