FreezeSubCell Method

Example 





The zero-based index of the sub-cell that is having its frozen status changed.
true to freeze the sub-cell, false to unfreeze the sub-cell.
Freezes the sub-cell.
Syntax
public void FreezeSubCell( 
   int subCellIndex,
   bool frozen
)
'Declaration
 
Public Sub FreezeSubCell( _
   ByVal subCellIndex As Integer, _
   ByVal frozen As Boolean _
) 
'Usage
 
Dim instance As MedicalViewerMultiCell
Dim subCellIndex As Integer
Dim frozen As Boolean
 
instance.FreezeSubCell(subCellIndex, frozen)
public void FreezeSubCell( 
   int subCellIndex,
   bool frozen
)
 function Leadtools.MedicalViewer.MedicalViewerMultiCell.FreezeSubCell( 
   subCellIndex ,
   frozen 
)
public:
void FreezeSubCell( 
   int subCellIndex,
   bool frozen
) 

Parameters

subCellIndex
The zero-based index of the sub-cell that is having its frozen status changed.
frozen
true to freeze the sub-cell, false to unfreeze the sub-cell.
Remarks
This method freezes only a sub-cell. To freeze or unfreeze the entire cell, use the MedicalViewerBaseCell.Frozen property.
