Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[Parameter]
public HorizontalAlignment? HorizontalAlignment { get; set; }

Property Value

Type	Default	Description
Nullable<HorizontalAlignment>	null	A HorizontalAlignment enumeration value; null if CSS classes define the horizontal alignment.

Available values:

Name	Description
Center	Center alignment.
Left	Left alignment.
Right	Right alignment.

Remarks

DevExpress CSS classes defined in the dx-blazor.css file determine the default Popup alignment. The Popup is centered both horizontally and vertically on the screen. You can also assign a custom CSS class to the Popup’s CssClass property.

Specify the HorizontalAlignment and VerticalAlignment properties to change the Popup position. These properties take priority over CSS classes.

<div @onclick="@(() => PopupVisible = true)">
    <p>CLICK TO SHOW A POP-UP WINDOW</p>
</div>

<DxPopup @bind-Visible="@PopupVisible"
         HeaderText="Header"
         BodyText="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris sit amet metus vel
             nisi blandit tincidunt vel efficitur purus. Nunc nec turpis tempus, accumsan orci auctor,
             imperdiet mauris. Fusce id purus magna."
         HorizontalAlignment="HorizontalAlignment.Right"
         VerticalAlignment="VerticalAlignment.Bottom" />

@code {
    bool PopupVisible { get; set; } = false;
}

You can also specify PositionX and PositionY properties to position the component at the specified coordinates. These properties have priority over HorizontalAlignment and VerticalAlignment properties.
