Hi
If I add a sheet to a workbook and then add in a data validation list, everything works OK.
I need to use conditional formatting so I am trying to open a template sheet (which copntains the conditional formatting) and then add the data validation list, but once saved, the workbook will not open and excel complains that its corrupt. This also happens if I try to add a validation list to a sheet that I have copied.
I assume that this is not expected behaviour so could you look into it, many thanks & well done with the project, its excellent!
Comments: Hi! In my project I add data-validation to an existing excel file. Unfortunately, I faced with this issue. This issue still exists in both EPPlus 3.1.3 and EPPlus 4.0.0beta. I've tried ted_250's solution but it doesn't help. Currently this means that List-DataValidation doesn't work at all. And I have no idea how to fix it. Please help me to fix data validation...
