The DevExpress controls are rich and complex and there are a number of ways to do this.

The simplest is probably to set a column's display format as follows:

gridColumn.DisplayFormat.FormatString = "N2";
gridColumn.DisplayFormat.FormatType = DevExpress.Utils.FormatType.Custom;

FormatString can be any of the .NET standard or custom format strings (look in MSDN or google for "Standard numeric format strings", "Custom numeric format strings").

For a devexpress XtraGrid you can use DevExpress.Utils.FormatInfo:

DevExpress.Utils.FormatInfo fi = new DevExpress.Utils.FormatInfo();
fi.FormatType = DevExpress.Utils.FormatType.Numeric;
fi.FormatString = "n2";
myColumn.DisplayFormat.Assign(fi);

If you also want to include the currency sign:

decimal price = 49.99M;
string data = price.ToString("c");

回答4:

Currency formatting depends on system settings, and sometimes it is better to specify precision explicitly:

double price;
string text=price.ToString("N2"); // N3 for 3 digits , etc
