Hello @Alexandre
I can not share my working sample because of confidential data.
But far away in my investigations I found the root cause of the bug:
Find is a method of RangeApi. So it Should works inside the given range. It does not ! In fact it run inside a range of the current sheet.
my work around : a call to oRange.GetWorksheet().SetActive() and then the oRange.Find(…) call is well working !
var oWorksheet = Api.GetActiveSheet();
oWorksheet.GetRange(“B1”).SetValue(2014);
oWorksheet.GetRange(“C1”).SetValue(2015);
oWorksheet.GetRange(“D1”).SetValue(2016);
oWorksheet.GetRange(“A2”).SetValue(“Projected Revenue”);
oWorksheet.GetRange(“A3”).SetValue(“Estimated Costs”);
oWorksheet.GetRange(“A4”).SetValue(“Cost price”);
oWorksheet.GetRange(“B2”).SetValue(200);
oWorksheet.GetRange(“B3”).SetValue(250);
oWorksheet.GetRange(“B4”).SetValue(50);
oWorksheet.GetRange(“C2”).SetValue(200);
oWorksheet.GetRange(“C3”).SetValue(260);
oWorksheet.GetRange(“C4”).SetValue(120);
oWorksheet.GetRange(“D2”).SetValue(200);
oWorksheet.GetRange(“D3”).SetValue(200);
oWorksheet.GetRange(“D4”).SetValue(160);
var oRange = oWorksheet.GetRange(“A2:D4”);
var oSearchRange = oRange.Find(“200”, “C3”, “xlValues”, “xlWhole”, “xlByColumns”, “xlNext”, true);
oSearchRange.SetFillColor(Api.CreateColorFromRGB(255, 213, 191));
you can try the code
Thank you, we are checking the situation.
