TdxSpreadSheetCellStyle.BeginUpdate Method

Disables repainting for the cell object.

Declaration

procedure BeginUpdate;

Remarks

Each time the cell object’s style settings are changed, the Spreadsheet or Report Designer control initiates repainting of the respective cell to reflect these changes.

To improve performance of a spreadsheet-based application, enclose the code that performs multiple cell style changes within the BeginUpdate/EndUpdate procedure blocks.

The BeginUpdate procedure postpones updates. To apply the changes made, invoke the EndUpdate procedure. Ensure that every call to BeginUpdate is followed by a call to the EndUpdate procedure, even if an exception occurs.
