   ByVal key As String _
) As ITBarButton

C#

public ITBarButton FromKeyIButton( 
   string key
)

Parameters

key

Remarks

The comparison of the keys are performed in a case-sensitive manner.

When an item of the given key is found, a check is performed of whether it is of a type implementing ITBarButton. If the matching item is not of an expected type, null is returned.

It is the application developer's responsibility not to add buttons with the same Key value to the collection of toolbar items. For optimal performance and robustness, the avoidance of duplicate key use within the same UltraWebToolbar is strongly recommended.

If the web application places subclassed TBarButton instances into the UltraWebToolbar element, then it should uniformly use this indexer to access those items.
