SubCellFrozen Method






Leadtools.MedicalViewer Namespace > MedicalViewerMultiCell Class : SubCellFrozen Method
The zero-based index of the sub-cell being checked.
Retrieves a value that indicates whether the sub-cell has been frozen.
Syntax
public bool SubCellFrozen(    int subCellIndex )
'Declaration   Public Function SubCellFrozen( _    ByVal subCellIndex As Integer _ ) As Boolean
'Usage   Dim instance As MedicalViewerMultiCell Dim subCellIndex As Integer Dim value As Boolean   value = instance.SubCellFrozen(subCellIndex)
public: bool SubCellFrozen(    int subCellIndex )

Parameters

subCellIndex
The zero-based index of the sub-cell being checked.

Return Value

true if the sub-cell is frozen; otherwise, false.
Remarks
This method retrieves the status for a sub-cell only. To check the frozen status for an entire cell use the MedicalViewerBaseCell.Frozen property.
