AdvancedDataGrid columns resizing is buggy

[tata668@gmail.com]

Resizing columns in an AdvancedDataGrid seems really buggy. Sometimes
all columns shrink except one that becomes way too big. Sometimes you try to
enlarge a column but when you release the mouse buton it shrink instead.

Am I the only one with those column resizing problem in AdvancedDataGrid? We
even had to add a "resizable = false;" to all columns because of this.

We have not seen this issue. It would help if you can post sample code which shows this behavior.

I'll try to make a shot sample but I don't have lots of time today. But here's a video from our QA team: [url]http://d352384.u25.nozonenet.com/open/ColumnResize.avi[/url]

Finally it's really easy to reproduce. The ADG doesn't even need to be binded
to a dataProvider for the bug to trigger:

To trigger an example of the buggy behavior, you just have to click (no drag)
at the right of the "field2" columns. Please, look at the image to know where
to click:

Any news if this is an official bug?

I'm not able to reproduce this issue.
I just copied the code you have given in a new mxml application. Do I need to do anything else to reproduce this issue.

Note: I'm using Flex 3 Released.

[tata668@gmail.com]

Hi,

Thanks for the reply.

Here, everyone is able to reproduce the bug using the provided code.

Flex Builder 3 pro, release version. Version: 3.0.194161

Also ran into this bug using FB3. Using standard DataGrid here.

Seems when you set the width of a column its ignored.

PreferedWidth and explicitWidth are correct but Width is as was originally.

My issue is I Show/Hide the grid an someitmes I Hide/Show the last column,
even setting widths explicitly they are still ignored.

Bump, thank you.

Any news about this? Thank you.

if I am not wrong then you are pointing out the error that by increasing the
width of one column why all other columns get shrinked?
This is infact a problem with ADG horizontal scroll bar. When horzitonal
scroll policy set to "auto" or "off' this problem occurs. But if you set scroll
policy equal to "on" then this problem of resizing will not occur

[Mirza Asim]

Theoratically, when scroll policy set to "auto", scroll bar should be appeared and columns on the right should go out the scroll window instead of shrinking.

Thanks a lot for the reply Mirza Asim!

I'm gonna try to set the scrollbar to "on".. I'm busy on other things today
but I'm gonna post my results here when done.

[tata668@gmail.com]

Setting the adg.horizontalScrollPolicy to "on" doesn't work.

The bug still occurs.

Any news on this?

Thank you

I was in the same situation until I commented headerSeparatorSkin: in my .css file. Without style, everything works fine.

I hope this help,
