How to mark a cell value as mandatory in excel. I have a sheet which contains 3 headers and I would like to mark the column values of header3 as mandatory from a possible set of values (i.e. even if the user doesn't select a value a default value should be set for the cell)

If You want to do with the help of c# code Try this : -
Worksheet ws;
Range oRng = ws.get_Range(StartCol + StartRow, EndCol + EndRow);
oRng.Validation.Add(XlDVType.xlValidateDecimal, XlDVAlertStyle.xlValidAlertStop, XlFormatConditionOperator.xlBetween, "StartVal", "EndVal");
oRng.Validation.IgnoreBlank = true;
oRng.Validation.InCellDropdown = true;
oRng.Validation.ErrorTitle = "Input Error";
oRng.Validation.ErrorMessage = "Please enter a numeric
value between "StartVal" and "EndVal""; oRng.Validation.ShowError = true;
where ws is the worksheet object, StartVal and EndVal are the range of values for which validation is to be checked

Use Validation on Cells where you want to perform these constraints.
Like : Select Range of Cells where you want to put this constraint.
Now open Data Validation
Dialog and Select List
from Allow
drop down in Setting Tab
. Provide your source
(possible values) in comma separate values
