FindFirstGraphicAnnSQItem Method
See Also 
Leadtools.Dicom Namespace > DicomDataSet Class : FindFirstGraphicAnnSQItem Method



Retrieves the first item under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module". Supported in Silverlight, Windows Phone 7.

Syntax

Visual Basic (Declaration) 
Public Function FindFirstGraphicAnnSQItem() As DicomElement
Visual Basic (Usage)Copy Code
Dim instance As DicomDataSet
Dim value As DicomElement
 
value = instance.FindFirstGraphicAnnSQItem()
C# 
public DicomElement FindFirstGraphicAnnSQItem()
C++/CLI 
public:
DicomElement^ FindFirstGraphicAnnSQItem();

Return Value

The first item under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module". null if No items were found.

Example

This example will initialize a new DICOM dataset, cerate a graphic annotation sequence and add a graphic object and text object under that sequence.
