Description
Returns the name of a custom attribute that can be retrieved using the GetItemAttr method.
Data.Bind.Components.TExpressionsDir.GetAttr inherits from System.Classes.TCollection.GetAttr. All content below this line refers to System.Classes.TCollection.GetAttr.
Returns the name of a custom attribute that can be retrieved using the GetItemAttr method.
TCollection descendants can associate user-defined attributes with the items in the collection. Each attribute has a name and, for each item in the collection, a value that is a string. The GetAttr method returns the name of an attribute.
Index identifies the attribute whose name is requested. This is a value between 0 and n-1, where n is the value returned by GetAttrCount.
As implemented by TCollection, GetAttr always returns an empty string, because TCollection defines no custom attributes.
