IDataValidation ListOfValues returns ArgumentOutOfRange exception

[Megan Clark]

Hi,

I am attempting to update a column within an existing excel workbook with list validation values retrieved from a database (listArray variable in code below).  A snippit of the code is:

//create column drop-down

IDataValidation validation = sheet.Columns[1].DataValidation;

validation.DataRange = sheet.Columns[1];

validation.ListOfValues = listArray;

validation.PromptBoxText = "List";

validation.IsPromptBoxVisible = true;

validation.ShowPromptBox = true;

An ArgumentOutOfRange exception is thrown on the validation.ListOfValues line because the combined string length is greater than 256 characters.  How do I get past this exception?
