Have shave you tried refreshing the dataProvider to get it to update the displayList on the itemRenderers or invalidating the displayList or properties of the grid?
Thanks for the reply john....
I tried both the ways bt its not working.
The default width of all the datagrid columns is 100 , i have not specified any width for any column.
I think i will have to specify the columns width on click of edit button. But m not sure whether its the only way or best way to do it.

Have you tried specifying a typicalItem?
Once you update the buttons, call the datagrid's validateNow() function. I think that should help.
(listdata.owner as datagrid) .validateNow();
// thats wat i did. but not working.
@John : TypicalItem may work but I am using Flex Builder 3 and i think it does not provide the typicalItem class in it.
