public void Load(
The Context Identifier (CID) of the Context Group to be loaded from the internal table. For a list of some possible values, refer to Context Identifier Values. If this parameter is set to a null reference (Nothing in VB), the method loads all the Context Groups that are currently unloaded.
You can add a Context Group to the Context Group Table either by loading it from the internal table maintained by LEADTOOLS or by inserting it directly into the Context Group Table. The Context Groups in the internal table are those defined by the DICOM Content Mapping Resource (DCMR). For a list of possible values, refer to Context Identifier Values. To insert a Context Group, use the Insert method. If the Context Group Table already contains a Context Group with the specified Context ID, the method will just return successfully. If the parameter contextID is set to a null reference (Nothing in VB), the method will load all the Context Groups that are not loaded currently, without affecting any Context Group that is already in the Context Group Table. (Therefore, to load all of the Context Groups in the internal table from the beginning, call the method with the contextID parameter set to null.)
If the method throws a DicomExceptionCode.Parameter exception, then this means that the internal table does not contain a Context Group with the specified Context ID.
For an example, refer to Insert.
