ExtensionElement.CanMerge Method
Returns a value indicating whether the source element represented by the specified root ProtoElement can be added to this element.
Namespace: Microsoft.VisualStudio.Modeling
Assembly: Microsoft.VisualStudio.Modeling.Sdk.10.0 (in Microsoft.VisualStudio.Modeling.Sdk.10.0.dll)
Syntax
'Declaration

protected override function CanMerge(

) : boolean
Parameters
- rootElement
Type: Microsoft.VisualStudio.Modeling.ProtoElementBase
The root ProtoElement representing a source element. This can be null, in which case the ElementGroupPrototype does not contain an ProtoElements and the code should inspect the ElementGroupPrototype context information.
- elementGroupPrototype
Type: Microsoft.VisualStudio.Modeling.ElementGroupPrototype
The ElementGroupPrototype that contains the root ProtoElement.
Return Value
Type: System.Boolean
true if the source element represented by the ProtoElement can be added to this target element.
Remarks
Override because we must ask the extended MEL whether it will accept the merge of ExtensionElements. This is necessary to allow us to refuse merges of MEXs that would create ambiguous roles or properties.
