I need to conditionally colorize ranges in a PivotTable. I tried to do it this way:
private void ColorizeContractItemBlocks(List contractItemDescs)
{
int FIRST_DESCRIPTION_ROW = 7;
int DESCRIPTION_COL = 1;
int ROWS_BETWEEN_DESCRIPTIONS = 4;
int rowsUsed = pivotTableSheet.Cells.Rows.Count;
int currentRowBeingExamined = FIRST_DESCRIPTION_ROW;
// Loop through PivotTable data, colorizing contract items
while (currentRowBeingExamined < rowsUsed)
{
Cell descriptionCell = pivotTableSheet.Cells[currentRowBeingExamined, DESCRIPTION_COL];
String desc = descriptionCell.Value.ToString();
if (contractItemDescs.Contains(desc))
{
// args are firstRow, firstColumn, totalRows, totalColumns
Range rangeToColorize = pivotTableSheet.Cells.CreateRange(
currentRowBeingExamined, 0,
ROWS_BETWEEN_DESCRIPTIONS, _grandTotalsColumnPivotTable + 1);
Style style = workBook.Styles[workBook.Styles.Add()];
style.BackgroundColor = CONTRACT_ITEM_COLOR;
StyleFlag styleFlag = new StyleFlag();
styleFlag.All = true;
rangeToColorize.ApplyStyle(style, styleFlag);
}
currentRowBeingExamined = currentRowBeingExamined + ROWS_BETWEEN_DESCRIPTIONS;
}
}
...but it doesn't work, because rowsUsed does not take into consideration the rows on the PivotTable on the pivotTableSheet, and so my while loop is never entered.
How can I determine how many rows the PivotTable takes up on the sheet, so that I can loop through the PivotTable?
Or, am I approaching this the wrong way? Is there a different standard way of manipulating the styles/formatting of a PivotTable after it has been generated?
