Comments on: Adding colspan to a datagrid

Out of the box, you can’t replace the whole row with a vbox. You can set the datagrid to editable=”true” and it will allow the user to click or tab into each cell and make edits, but not the whole row.

Okay, I’m presently in need of help desperately. I need a user to double-clcik a datagrid row and the row is repalced with a vbox with the detail data of the row. e.g. if the row had first name, last name, age, sex, and so on. When the user clicks that row, the row is replaced with a vbox which is supposed to be the detail view. Anyone with any clue as to how to progress on this?

Should just be (using my example) htmlText=”{ parentDocument.text }”, as long as the value is bindable.

Seems it can not show tag…

ArrayCollection #
[0] = Object name=”1″ location=”loc1″ exp=”333″ text=”123″
[1] = Object name=”2″ location=”loc2″ exp=”333″ text=”456″

Hey KR,
Not sure I understand about the “vertical scroll bar effect”. A scroll bar will appear in certain rows if you do not make the row “tall” enough for the content within it (I just encountered this recently while testing). However, if you know roughly the height of the content, it will not have the scroll bar if you set the height with enough room. If you do a percentage height, I’ve found that it sets the height correctly on initial load, but has trouble maintaining that full 100% and will occasionally show the scroll bars when scrolling up and down the datagrid. I think this is a refresh issue with the way Flex calculates the height, so setting the value explicitly seems to work the best.

And yes, the header remains at the top during the scroll.

Thanks for reading.

Hi, what about vertical scroll bar effect for this All-MixedDataGrid (Though there should be some collective name for your intelligent work)? Would the header remain in top when you scroll down just like the actual data grid?

Thanks for sharing your ideas…

@bruce,
Glad to be of assistance. Any improvements you have, feel free to send them along. I’m sure there are some things I could change.

This was an awesome jumping off point for me.

I used 1 DataGrid, 1 List, and 1 smart ItemRenderer that has contained areas, 1 for the normal columns which are dynamically generated from the first Header DataGrid. Makes it easy for resize and moving of the columns.

Geez! Cause me more grief, why dontcha

1. You are correct. This is something I’ll need to fix. Shouldn’t be too bad though…just need to match up the column order “on column move”.

2. Expanding a single row should work OK. Right now they are all tied to the external data value, but as they’re all itemRenderers internally, it should just be expanding based upon something internal (like a button click, etc.)

Thanks for thinking of some other possibilities that need to be thought through.
