DxToolbar.AdaptivityMinRootItemCount Property

Specifies the minimum number of root items shown in the Toolbar when the browser window’s width changes.

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v23.2.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(0)]
[Parameter]
public int AdaptivityMinRootItemCount { get; set; }

Property Value

Type	Default	Description
Int32	0	An integer value that specifies the minimum number of items.

Remarks

The Toolbar component supports adaptive mode. The following properties specify how the toolbar responds when the container’s width changes:

• AdaptivityAutoCollapseItemsToIcons - If true, the text of all items that contain icons is hidden.
• AdaptivityAutoHideRootItems - If true, the toolbar moves root items one by one to the root submenu until the root level reaches the minimum allowed number of items (specified by the AdaptivityMinRootItemCount property). You can also use the AdaptivePriority and AdaptiveText properties to hide an individual item before other items and specify alternative item text for adaptive mode.
