Hi
Only work around for this is, need to find the maximum len of your field value then using Left(), Mid() functions you need to cut the string and in the report concatente all the strings.
Ex :
@String1 :
left({fieldvalue},254)
@String2 ;
Mid({fieldvalue},255, 509)
.
.
.
.
Finally you create one formula like :
@string1+String2+....
This will display entire field value.
