ExpansionProvider.IsValidType Method
Determines whether or not a given type is valid for expansion purposes. This method should be overridden if you want to specify where in the source document the expansion can take place.

Parameters
- buffer
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLines
The IVsTextLines buffer.
- ts
Type: array<Microsoft.VisualStudio.TextManager.Interop.TextSpan[]
An array of TextSpan objects.
- rgTypes
Type: array<System.String[]
An array of expansion types.
- iCountTypes
Type: System.Int32
The number of expansion types in the rgTypes array.
- fIsValid
Type: System.Int32%
[out] Returns true if the type is valid, otherwise false.
Return Value
Type: System.Int32
When overridden in derived classes, S_OK if the method succeeds, otherwise an error code.
Implements
IVsExpansionClient.IsValidType(IVsTextLines, array<TextSpan[], array<String[], Int32, Int32%)
Remarks
This method by default checks only that buffer is the same as the IVsTextLines of Source; it will throw an ArgumentException if not. Implementers must override this method if they wish to specify where in a document a given expansion can be performed.
