Apply text alignment in Excel comments using EPPlus
  • First, we need to attach OfficeOpenXml.Drawing.Vml, this namespace is required for text alignment of excel comment.
  • In the Part-4 video, we have seen how to apply text alignment in Excel cell text but in this video I will show you how to apply text alignment in Excel comments. There are two type of alignments 1) VerticalAlignment & 2) HorizontalAlignment.
  • These alignments are the property of Excel comment class and these are assigned by eTextAlignVerticalVml and eTextAlignHorizontalVml enum.


    1. using(ExcelRange Rng = wsSheet1.Cells["B5"]) {
    2. Rng.Value = "Everyday Be Coding";
    3. ExcelComment cmd = Rng.AddComment(LongText, "Rajdip");
    4. cmd.AutoFit = true;
    5. cmd.Visible = true;
    6. //set alignment in excel comment
    7. cmd.VerticalAlignment = eTextAlignVerticalVml.Center;
    8. cmd.HorizontalAlignment = eTextAlignHorizontalVml.Center;
    9. }
  • In this above code VerticalAlignment & HorizontalAlignment properties are assigned by eTextAlignVerticalVml & eTextAlignHorizontalVml enum.
