RE: [flexcoders] Re: Sort: Datagrid sorting numbers and strings

[Alex Harui]

You'll get errors if objects in the collection are missing properties mentioned 
in the sortFields, I think the first element is tested.

Your compare function will have to determine if the string is a number and if 
both are numbers, convert them to number and compare.  For IP addresses you 
have to break them into their four parts convert to numbers and compare

Subject: [flexcoders] Re: Sort: Datagrid sorting numbers and strings





Ok, so I am closer.

If I have this:

192.168.168.12
192.168.168.129
192.168.168.24
hellokitty
bigsmelly

When sorting I get this (with the normal flex sorting):

192.168.168.129
192.168.168.12
192.168.168.24
bigsmelly
hellokitty

And if I use my own sort function and perform several sorts quickly I get an 
Error:

"Find criteria must contain at least one sort field value "

My sort function:

private function testCompareFunc(itemA:Object, itemB:Object):int {
var valueA:String = itemA;
var valueB:String = itemB;
return ObjectUtil.stringCompare(valueA, valueB);
}

Any suggestions? Not sure how to do a string and number comparison.

TIA

[flexcoders] Re: ambiguous reference error

[Tim Hoff]

Are you by any chance using a getter/setter for the isValid var?  If so, you 
may need to change the setter to public.

Re: [flexcoders] ambiguous reference error

[[p e r c e p t i c o n]]

Hi Tracy,that was a mistake, actually i called it 'isValid' like this




is valid is a boolean that i declared in my code-behind

also

i noticed that when i put defaultButton in the root node of my mxml
component it does the same thing...

very confused

RE: [flexcoders] Flex 4 Profiling Question - GC Root?

Somewhere you can adjust the cut off of how many paths to root are filtered 
out.  I don't have the UI handy right now

I'm curious about this part about filtering out chains with very long
paths. I've come across quite a few instances of loitering objects in
the FB 4 profiler that don't show any back references. When you expand
the reference it just lists itself and it says that it is a GC root
node. But then doing some really aggressive stuff to try to free up
all possible references does indded get those items collected (meaning
that I don't think it can be blamed on the GC simply not running when
I took my snapshot, etc).

Could this be because there are filtered out chains that I'm not
seeing? Is there any way to selectively turn any kind of filtering
like this off?

I think I understand why. The dataprovider in the example is the actual XML 
List. I was wrapping the XML List in an XML List Collection so it wasn't 
updating the underlying dataprovider.

[flexcoders] Re: Dispatch Event Issue on BreadCrumb Trail Click

Looks like you may be thinking about a little backwards.  First add this
method to the script in contentpane:

import mx.events.ItemClickEvent;

public function handleBreadCrumbItemClick( event:ItemClickEvent ):void
{
  // do something
}

Then Main.mxml would have:

different manner. I believe I was using the following:

private function endEdit(event:DataGridEvent):void {

trace('event.itemRenderer.data - ' + 
event.itemRenderer.data)

}
I will try your method and am guessing that it will work. 

Thanks for the assistance.

[flexcoders] Re: Sort: Datagrid sorting numbers and strings

[flexaustin]

Ok, so I am closer.

If I have this: 

192.168.168.12
192.168.168.129
192.168.168.24
hellokitty
bigsmelly

When sorting I get this (with the normal flex sorting):

192.168.168.129
192.168.168.12
192.168.168.24
bigsmelly
hellokitty


And if I use my own sort function and perform several sorts quickly I get an 
Error:

"Find criteria must contain at least one sort field value "

My sort function:
 
private function testCompareFunc(itemA:Object, itemB:Object):int {
var valueA:String = itemA;
var valueB:String = itemB;
return ObjectUtil.stringCompare(valueA, valueB);
}

Any suggestions? Not sure how to do a string and number comparison.

TIA

[flexcoders] Re: ArrayCollection and Datagrid Binding and DataProvider Question

I didn't know this.

When I tried it, it didn't update the dataprovider. Is there anything special 
that needs to happen.

You may need to use a custom DataDescriptor.

In my application i am using the tree control and the data for tree is

level dtos represents the leaf nodes of that branch node.

I am not able to combine as data provider for the tree control.The list here
i am talking is ArrayCollection.

Please can any body suggest, how to make this list as the data provider.

RE: [flexcoders] Re: ArrayCollection and Datagrid Binding and DataProvider Question

Data  binding in general is not two-way, but an editable datagrid is a
special case.  It will update the dataProvider items automatically.

DataProvider Question

 






Basically, no. The datagrid is like a window into your dataprovider.

If you need to modify your dataprovider you need to listem for the
itemEditEnd event, grab the data that was modified and update the underlying
dataprovider.

The data binding will note that the dataprovider has changed and will update
the datagrid on the next redraw.

What data binding does is add an event dispatcher to the variable you have
defined as bindable. When the variable changes an event is generated to let
any component that is bound to that variable know that the variable has
changed and update itself with the new data.

Now, As I understand it (And I could be wrong) Flex 4 (Gumbo) does do full
two way data binding. I have not read up on what or how it does this but it
sounds interesting.

Sorry, I meant to follow up on this yesterday.  Thanks for your reply but I

Can you try removing some of those series to isolate the problem?
Also, can we see the console output from the trace statements in

Maybe the values are out of bounds? Some sample data would be useful

[flexcoders] Re: Datagrid - Using and Editing Data From XMLListCollection

[azona26]

Thanks for the help. I did try using an itemEditEnd eventlistener. The issue I 
was having was that the data value wasn't being changed it was still the 
original value.

[flexcoders] Re: ArrayCollection and Datagrid Binding and DataProvider Question

[valdhor]

Basically, no. The datagrid is like a window into your dataprovider.

If you need to modify your dataprovider you need to listem for the itemEditEnd 
event, grab the data that was modified and update the underlying dataprovider.

The data binding will note that the dataprovider has changed and will update 
the datagrid on the next redraw.

What data binding does is add an event dispatcher to the variable you have 
defined as bindable. When the variable changes an event is generated to let any 
component that is bound to that variable know that the variable has changed and 
update itself with the new data.

Now, As I understand it (And I could be wrong) Flex 4 (Gumbo) does do full two 
way data binding. I have not read up on what or how it does this but it sounds 
interesting.

[flexcoders] Re: Datagrid - Using and Editing Data From XMLListCollection

[valdhor]

You would need to add an event listener for the itemeditend event. Then grab 
the data that was edited and modify the dataprovider.

Re: [flexcoders] Re: Label a Button just like Flex Builder helps

[Harish Sivaramakrishnan]

While you add the child (TextInput) , make a dictionary to track the
childIndex or even better the instance itself and bump it off once you
complete the editing

[flexcoders] Re: Label a Button just like Flex Builder helps

[chandruflex]

Ok, I can use removeChildAt() for the question that I have asked. Actually I 
had to think about the next step. In my application, I will have a lot of other 
components (both statically and dynamically created). One or many of those 
dynamically created components may be Button components.

[flexcoders] Re: Dispatch Event Issue on BreadCrumb Trail Click

[n_manjunatha]

Hi Tim
Thanks for your time and reply. Yes you are right, I am not using MVC 
Framework. 

I tried this
my main.mxml is like this...of course not with exact format of flex...
script
{
 breadcrumclicked(event:Event) which comes canvas below
}





I guess i cant send the public method breadcrumclicked(event) in
my contentpane bcoz i cant give something like this


i tried this it doesnt work..it says cant resolve attribute breadcrumclicked 
for contentpane.

Thanks

Re: [flexcoders] Read Items / Loop Through Datagrid Rows

[Harish Sivaramakrishnan]

use the itemEditEnd event on the DataGrid to get the value you entered in
the TextInputs. (It is fired when you tab out or change focus from rows.)

That's a lot ! You could probably serve your users better by having a small
