grid - Devexpress Double conditional FormatString -

i'd conditionally change formatstring property of grid's column.

the input double.

what want following :

if (cellvalue % 1 == 0)     acolumn.displayformat.formatstring = "n0"; else     acolumn.displayformat.formatstring = "n2"; 

is there way @ runtime without having check each value of column ?

any appreciated, !

you can use approach witn handling columnview.customcolumndisplaytext event demonstrated @kenrogers.

or can use custom formatting feature column:

acolumn.displayformat.formattype = devexpress.utils.formattype.custom; acolumn.displayformat.format = new customdoubleformatter();  public class customdoubleformatter : iformatprovider, icustomformatter {     public object getformat(type format) {         return this;     }     public string format(string format, object arg, iformatprovider provider) {         bool hasfractionalpart = ((double)arg % 1.0 > double.epsilon);         return string.format(hasfractionalpart ? "{0:n2}" : "{0:n0}", arg);     } } 

p.s. more detail formatting cell values refer formatting cell values article.
