Why does setting a color to a cell not work (Aspose Cells)? - excel

Question

I have this code to try to set the background color of a cell (among other things):
private static readonly Color CONTRACT_ITEM_COLOR = Color.FromArgb(255, 255, 204);
. . .
cell = pivotTableSheet.Cells[4, 0];
cell.PutValue(AnnualContractProductsLabel);
style = cell.GetStyle();
style.HorizontalAlignment = TextAlignmentType.Center;
style.VerticalAlignment = TextAlignmentType.Center;
style.Font.IsBold = true;
pivotTableSheet.Cells.SetRowHeight(4, 25);
style.BackgroundColor = CONTRACT_ITEM_COLOR;
pivotTableSheet.Cells[4, 0].SetStyle(style);
The setting of horizontal and vertical alignment works, as does bold and height - everything but color:
What is yet needed? I have even tried setting ForegroundColor as well as Background colors, to :
style.ForegroundColor = Color.Red;
style.BackgroundColor = Color.Blue;
...but neither does anything - the cell still looks exactly the same as the screenshot above.

Answer 1

Please change your code segment to (see the highlighted lines):
e.g
Sample code:
. . .
cell = pivotTableSheet.Cells[4, 0];
cell.PutValue(AnnualContractProductsLabel);
style = cell.GetStyle();
style.HorizontalAlignment = TextAlignmentType.Center;
style.VerticalAlignment = TextAlignmentType.Center;
style.Font.IsBold = true;
pivotTableSheet.Cells.SetRowHeight(4, 25);
**style.ForegroundColor = CONTRACT_ITEM_COLOR;
style.Pattern = BackgroundType.Solid;**
pivotTableSheet.Cells[4, 0].SetStyle(style);
..........
it should work fine.

Sometimes setting background works, sometimes it doesn't. Aspose is full of bugs -- ClosedXML is much more reliable but harder to use. Wish I would not have spent the money on a product that was developed by third party in third world county.
var cells = worksheet.Cells; //get cells collection from active worksheet <br>
var srcCells = workbook.Worksheets[1].Cells;<br>
for (int i = 0; i<rowCount; i++)<br>
{<br>
var srcStyle = srcCells[i, 0].GetStyle();<br>
var destStyle = cells[i, 0].GetStyle();<br>
destStyle.Pattern = BackgroundType.Solid;<br>
destStyle.ForegroundColor = Color.FromArgb(srcStyle.ForegroundArgbColor);<br>
cells[i, 0].SetStyle(destStyle);<br>
}<br>
Above Code does not work. srcStyle Foreground color argb is 170,215,255.
Debugging code destStyle ForegroundColor is set to 170,215,255 but when saved as xlsx all the cell backgrounds are white.
In ClosedXML code the following code works perfectly
worksheet.Row(i).Cell(0).Style.BackgroundColor = Color.FromArgb(argb)
Conclusion: Save $$$$$ and use ClosedXML
