Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(10)]
[Parameter]
public double PaddingTopBottom { get; set; }

Property Value

Type	Default	Description
Double	10	The padding in pixels.

Remarks

Based on the VerticalAlignment property value, the PaddingTopBottom property moves the constant line label up or down.

The following example uses spin editors to change top/bottom and left/right paddings for the constant line label:

<div ...>
    <label>PaddingLeftRight</label>
    <DxSpinEdit @bind-Value="@PaddingLeftRight" />
    <label>PaddingTopBottom</label>
    <DxSpinEdit @bind-Value="@PaddingTopBottom" />
</div>
