[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 control how the toolbar responds when the container’s width changes:

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