TdxSpreadSheetAlignVerticalCenter Class

An action object that implements the AlignVerticalCenter end-user command in Spreadsheet and Report Designer-based applications.

Declaration

TdxSpreadSheetAlignVerticalCenter = class(
    TdxSpreadSheetCustomAlignVerticalAction
)

Remarks

This class does not introduce any new public members. Its overridden Execute function call centers the content between the top and bottom borders of all cells selected in the active worksheet. As a result, the Style.AlignVert property of all affected cell objects is set to ssavCenter.

If the content is already centered between the top and bottom borders in all selected cells, the AlignVerticalCenter command has no effect.

UI elements linked to a TdxSpreadSheetAlignVerticalCenter action object are enabled only if the following conditions are met:

Spreadsheet document edit operations are allowed (that is, the control’s OptionsBehavior.Editing property is set to True).
An in-place cell editor is inactive (the active worksheet’s IsEditing property returns False).
At least one cell is selected (the command is unavailable if a floating container is selected or the protected worksheet’s OptionsProtection.ActualAllowSelectUnlockedCells property returns False).
Cell formatting is allowed (the active worksheet’s OptionsProtection.ActualAllowFormatCells property returns True).
