RE: [flexcoders] [Flex 1.5] Update ColumnData with new data

[Jonathan Miranda]

Your easiest bet for this is to have a cellRenderer send an event out when you leave the cell and update the dataprovider accordingly in a function which will update the datagrid. If you’re unlucky like me, I had to have selectable=false and it was giving me a headache trying to figure this out (knowing which row I was on) – but I got the final answer after a long list of emails. Things to note first about this: -my cell renderer had to have implements="mx.controls.listclasses.IDropInListItemRenderer" because I need access to listdata -you can’t get to selectedIndices or anything of the like if your selectable=false, so that’s why I had to use the vPosition -the idea is you bubble an event out from the cell you’re editing, find out what row it is (and column in your case) and change the dataprovider. Here’s the code for finding the row: (resultsDG is my datagrid, the stuff inside the brackets is the row position and compare is my column) resultsDG.dataProvider[e.target.parent.listData.owner.vPosition+e.target.parent.listData.rowIndex-1].compare   Try tackling the extension of the cellrenderer to get the listData and if you got questions I can provide more examples. _________________________________________ Jonathan Miranda Flexible Master of the Web "Try not to become a man of success, but a man of value." - Albert Einstein HealthGrades: Guiding America to Better Healthcare™ NASDAQ: HGRD w  (720) 963-3832 c  (707) 761-0868 [EMAIL PROTECTED] _________________________________________ The message contains confidential and/or legally privileged information and is intended for use only by the indicated addressee.  If you are not the named addressee you should not disseminate, distribute, or copy this e-mail.

And then if I say edit the 3rd column with a different value, the succeeding columns should update with the new value.   What would be the most efficient way to achieve this?   Maybe I should try to generically find the "newValue" of a cell and then assign it by rowIndex-columnIndex?   Thanks Sree -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!
