DxGrid.PagerAutoHideNavButtons Property

Specifies whether arrow navigation buttons are hidden when all numeric buttons are displayed in the pager.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v24.1.dll

NuGet Package: DevExpress.Blazor

Declaration

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

Property Value

Type	Default	Description
Boolean	true	true to hide navigation buttons when all numeric buttons are displayed; false to display navigation buttons in addition to numeric buttons.

Remarks

In numeric buttons mode, you can use the PagerVisibleNumericButtonCount property to specify the maximum number of buttons displayed in the pager simultaneously. A user should click arrow navigation buttons to display other numeric buttons.

The pager hides arrow navigation buttons if all numeric buttons are displayed (that is, the total page count in the Grid is less than or equal to PagerVisibleNumericButtonCount).

To disable this behavior and display navigation buttons permanently, set the PagerAutoHideNavButtons property to false.
