Conditional Formatting by Expression using EPPlus

Question

I\'m trying to format some range by using conditional Formatting feature of EPPlus. I read many document but there is nowhere mentions about Conditional Formatting Expressio

Answer 1

After many moons I found way more flexible and fast approach to do this using LINQ and EPPlus. All you need to do is: add extra property to your list to save Excel Row Numbers, and then retrieve cell addresses using LINQ. In this case it would look like this:

string sRng = string.Join(",", YourModel.Where(f => f.YourField == null)
    .Select(a => "H" + a.iRow + ",L" + a.iRow + ",AA" + a.iRow)); // this address could be many pages and it works

if (sRng.Length > 0) {
    ws.Cells[sRng].Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.Green); 
}
