You can also specify custom date formats. For a complete list of format characters and more information on creating custom date formats, see Date and Time Format Strings in the Microsoft .NET Framework Developers Guide.

The following example creates a date-time cell with a message to display for invalid data and a custom date format. The date format displays the weekday, a comma, and then the month and day for the specified date. The column width is set to display all the text.

C#

FarPoint.Web.Spread.DateTimeCellTypedatecell=new FarPoint.Web.Spread.DateTimeCellType();
datecell.ErrorMessage="Needadate!!!";
datecell.FormatString="d";
FpSpread1.Sheets[0].Cells[0,0].CellType=datecell;
FpSpread1.Sheets[0].Cells[0,0].Value=System.DateTime.Now.ToOADate();
FpSpread1.Sheets[0].Columns[0].Width=175;

Visual Basic

Dim datecell As New FarPoint.Web.Spread.DateTimeCellType()
datecell.ErrorMessage="Needadate!!!"
datecell.FormatString="d"
FpSpread1.Sheets(0).Cells(0,0).CellType=datecell
FpSpread1.Sheets(0).Cells(0,0).Value=System.DateTime.Now.ToOADate()
FpSpread1.Sheets(0).Columns(0).Width=175
