Retrieves the tag (overlay text) for a cell.

Syntax

C#
Visual Basic
Objective-C
Java
C++

public MedicalViewerTagInformation GetTag( 
   int row,
   MedicalViewerTagAlignment alignment
)

'Declaration
 
Public Function GetTag( _
   ByVal row As Integer, _
   ByVal alignment As MedicalViewerTagAlignment _
) As MedicalViewerTagInformation

'Usage
 
Dim instance As MedicalViewerBaseCell
Dim row As Integer
Dim alignment As MedicalViewerTagAlignment
Dim value As MedicalViewerTagInformation
 
value = instance.GetTag(row, alignment)

public:
MedicalViewerTagInformation^ GetTag( 
   int row,
   MedicalViewerTagAlignment alignment
)

Parameters

row: The line at which the overlay text is placed.
alignment: The overlay text alignment.

Remarks

This method will retrieve the cell tag. The cell tag is a tag that appears on all the cell frames. To retrieve the sub-cell the tag use the MedicalViewerMultiCell.GetTag method.
