>> when i moving from screen to screen, the columns in ADG are resizing.
I don't understand what you mean with this.
Could you explain a little bit more? Maybe with some screen shots?

 

by: vmaradaPosted on 2009-07-01 at 23:04:43ID: 24760766

I mean, when i navigate from any screen to Datagrid screen, i observed that the width of the columns are changed.

 

by: zzynxPosted on 2009-07-02 at 00:19:25ID: 24761048

First of all, as far as I know that isn't standard behaviour at all.

In the Flex help file I read (for the width property of AdvancedDataGridColumn):
The width of the column, in pixels. If the AdvancedDataGrid's horizontalScrollPolicy property is false, all visible columns must fit in the displayable area, and the AdvancedDataGrid will not always honor the width of the columns if the total width of the columns is too small or too large for the displayable area.

Is the horizontalScrollPolicy property of your AdvancedDataGrid set to true? Otherwise the above indicates the width settings won't always be honored.

If that doesn't help, the only thing I can think of are the renderers. You could do a test and remove all renderers and see if the problem persists.

horizontalScrollPolicy wasn't set. however, i dont want to show the horizontal scroll bar.
even i remove all the renderers also, the columns are resizing in the datagrid.

>> even i remove all the renderers also, the columns are resizing in the datagrid.
Seriously?
There must be something else in your program causing this. I've never heard of such behaviour be default.

 

by: vmaradaPosted on 2009-07-02 at 10:10:47ID: 24765415

There is no manipulation of widths anywhere in my program. i need the renderers also. how to overcome this?

 

by: zzynxPosted on 2009-07-02 at 23:37:29ID: 24770395

>> There is no manipulation of widths anywhere in my program
Then it must be possible to write a small application - just containing two windows; one empty and one having a DataGrid - that demonstrates this behaviour.

 

by: vmaradaPosted on 2009-07-06 at 07:46:02ID: 24785693

Example is working fine. but i don't know why it is behaving like that in my application.

 

by: zzynxPosted on 2009-07-07 at 04:25:12ID: 24793172

>> Example is working fine.
That's what I suspected

>> but i don't know why it is behaving like that in my application.
For me there's only one possibility to detect that: I need to see all your code. But I don't know if that is acceptable/feasable for you.

 

by: vmaradaPosted on 2009-11-04 at 03:53:39ID: 31598379

ok

 

by: zzynxPosted on 2009-11-04 at 04:00:28ID: 25738426

Thanx 4 axxepting
So you found why it behaved like that?
