TdxSpreadSheetCell Class
A logical cell designed to store, arrange, and process data within a Table View worksheet.
Declaration
TdxSpreadSheetCell = class(
TdxDynamicListItem,
IdxSpreadSheetCellData,
IdxSpreadSheetCellStyleOwner
)Remarks
The cell object concept was designed to reduce the control’s memory consumption. A newly created blank Table View worksheet has no cell objects. A TdxSpreadSheetCell object is created on demand and stores both the cell data (whether it is a value, formula expression, or an error code) and accompanying custom cell appearance and behavior settings.
The TdxSpreadSheetCell class extends its ancestor with the following members that allow you to:
Assign the value of a specific type to the cell object or convert its current value to the required type (AsBoolean, AsCurrency, AsDateTime, AsFloat, AsFormula, AsInteger, AsString, and AsVariant);
Replace the current cell value with a formatted RTF string (SetAsRTF);
Retrieve formatted text from the cell object (GetAsRTF);
Identify whether the cell object has a value (HasValue);
Identify the type of data currently stored within the cell object (DataType);
Customize appearance and behavior of the cell object (Style);
Move the cell object to the specified location within the Table View worksheet (Column, ColumnIndex, Row, and RowIndex);
Obtain a reference to the cell object for the use in formula expressions and defined names (GetReference);
Remove the stored value from the cell object (IsEmpty and Clear);
Obtain the Table View worksheet to which the cell object belongs (View).
Spreadsheet controls create a TdxSpreadSheetCell object when:
A user assigns a new value via an in-place cell editor or an associated formula bar;
Customizes an empty cell’s appearance.
To create a cell object, you can:
Call a worksheet’s CreateCell function;
Call the CreateCell function that both columns and rows provide.
The TdxSpreadSheetTableView.Cells and TdxSpreadSheetTableItem.Cells properties reference a TdxSpreadSheetCell object.
