How to programmatically change the Icon value and type on a conditionnal formatting

Hello,

In an Excel file, I want to add, on specific cells, a conditionnal formatting, displaying a green arrow when the value is strictly positive, yellow arrow for 0, and red for negative values.
Thus, I’ve used the following (simplified) code:

Workbook book = new Workbook();
Worksheet sheet = book.getWorksheets().get(0);
// Add some data for the example…
sheet.getCells().get(“B2”).setValue(-0.1);
sheet.getCells().get(“C2”).setValue(0);
sheet.getCells().get(“D2”).setValue(0);
sheet.getCells().get(“E2”).setValue(1);
// Set conditional formatting info…
ConditionalFormattingCollection cfc = sheet.getConditionalFormattings();
int index = cfc.add();
FormatConditionCollection fcc = cfc.get(index);
CellArea area = new CellArea();
area.StartRow = 1;
area.EndRow = 1;
area.StartColumn = 1;
area.EndColumn = 4;
// Use Icon Set
index = fcc.addCondition(FormatConditionType.ICON_SET);
fcc.addArea(area);
FormatCondition fc = fcc.get(index);
fc.getIconSet().setType(IconSetType.ARROWS_3);
fc.getIconSet().setShowValue(false);
// There is something missing here…

// Save
book.save(“foo.xlsx”);

However, with this code, the conditions are based on % values (green for >= 66%, yellow for 33%, red otherwise) - cf. “what I have.jpg” screenshot.

So I want to change that configuration programmatically (cf. “what I want.jpg” screenshot). How do I do that?

What I’ve tried is to use the fc.getIconSet().getCfvos() method, but without success, for example doing that changed nothing in my Excel file :

ConditionalFormattingValueCollection cfvc = fc.getIconSet().getCfvos();
index = cfvc.add(FormatConditionValueType.NUMBER, “0”);
ConditionalFormattingValue cfv = cfvc.get(index);
cfv.setGTE(false);

Thanks.

Romain.

ps: We are using Java 1.6, Aspose Cells 7.0.3.

Hi,

Please download and try the latest version:

Aspose.Cells for Java 7.1.2


If the problem still occurs, then please provide us your actual output xls/xlsx file and your expected output xls/xlsx file.

You can create both of them manually using Ms-Excel 2010 and post here.

It will help us to figure out a solution for your problem and we will provide you a sample code or a workaround.

Hi,

Because for the iconset ARROWS_3, there are only the first three value objects take effect and they have been initialized when you set the iconset type, so please change your code as following:

Java




ConditionalFormattingValueCollection cfvc = fc.getIconSet().getCfvos();

ConditionalFormattingValue cfv = cfvc.get(1);

cfv.setType(FormatConditionValueType.NUMBER);

cfv.setValue(0);

cfv = cfvc.get(2);

cfv.setType(FormatConditionValueType.NUMBER);

cfv.setValue(0);


Hello,

Thanks for your answer, I succeed to solve my issue. The exact code is:

int index = fcc.addCondition(FormatConditionType.ICON_SET);
fcc.addArea(area);
FormatCondition fc = fcc.get(index);
fc.getIconSet().setType(IconSetType.ARROWS_3);
fc.getIconSet().setShowValue(false);
// Set conditions
ConditionalFormattingValueCollection cfvc = fc.getIconSet().getCfvos();
ConditionalFormattingValue cfv = cfvc.get(1);
cfv.setType(FormatConditionValueType.NUMBER);
cfv.setValue(0);
cfv.setGTE(true);
cfv = cfvc.get(2);
cfv.setType(FormatConditionValueType.NUMBER);
cfv.setValue(0);
cfv.setGTE(false);

Hi,

Thanks for sharing the code example.
