Item close event is triggering twice for Advanced Data Grid

HI, I'm using AdvancedDataGrid for my project. My issue is when click on item close, the item close event is triggering twice. Why it is triggering twice? Thank you...

Hi,
Would you mind reposting your question over on the Flex forums? You'll most likely have better luck over there.
Thanks,
Chris

Ah! the delights of advanced data grid!

I have a xml hierarchical advanced data grid.
Is there a way to disable the folderIcons for the advanceddatagrid?
Or is there a way to integrate the folderIcon actions to selected row actions?
Right now, I have a listener for itemOpen. When one folder opens, then another one will close. However, when the user clicks on the folderIcon....it does not do this. I do not know how to access the expandeditem of the advanceddatagrid.
Thank you for your help!
Emma
* Also, the fonts are being embedded by css...when you click on the folder...the fonts jump while they are being propagated. suggestions?

That is a great idea...except I am using the selectRow to use these same events.
It seems what I need is access to the same selectedItem.
When I click on the row, I pass through _selectedItem from the event function.
However, it is a little bit more complicated for the drop down buttons.
I try to get the same format with this:
selectedItem=IHierarchicalCollectionView(adg.dataProvider).openNodes;
but I get an [object][object]
I found this bit of code on a site:
import mx.collections.HierarchicalCollectionView;
myOpenNodes:Array = new Array();
var HierColView:HierarchicalCollectionView = HierarchicalCollectionView(myADG.dataProvider);
for each ( var item:Object in HierColView.openNodes ) {
myOpenNodes.push(item);
myADG.dataProvider.openNodes = myOpenNodes;

Advanced Data Grid datasource Arraycollection addItem extremly slow

Hello everyone,
i want to add 2000 items to my existing arraycollection, which is the datasource for the Advanced Data Grid i made.
here is the code:
for(var i:int;i<res.length;i++) {
var swap:myDataGridObject = incomingdataarray[i];
datasourcearray.addItemAt(swap,i);
it takes about 2 minutes .... thats very slow, thinking of one is waiting 2 minutes every time he expanded a node in the tree.
as a solution i tryied to do it like this:
datasourcearray = new ArrayCollection( ObjectUtil.copy( incomingdataarray.source ) as Array );
the result is that it is actually working, but i can not expand my treenodes any longer. there seemed to be no items in there.
adatagrid.valdiatednow() also has no effect.
perhaps anybody came across the same thing an can help me out
thanks
steff

Hi,
first, thank u for your fast answer. I try to add Items to a ArrayCollection which is the dataprovider from my ADG.
i did this in this way:
for(var i:int;i<incomingDataArray.length;i++) {
var swap:myObject = incomingDataArray[i];
datasourceAC.addItemAt(swap,i);
i get the data from another method in form of a array collection, which contains many of the myObjects Elements.
The datasourceAC is the provider as mentioned above. the only way it works for me to add the items to the dataSourceAC and the ADG beeing updated in the
correct way is this one. but its very slow....
now i tried your hint like this:
var sourceArray:Array = datasourceAC.source;
for(var i:int;i<incomingDataArray.length;i++) {
var swap:myObject = incomingDataArray[i];
sourceArray.push(swap);
datasourceAC.refresh();
the result is that the nodes are loaded an displayed but i can not expand them any longer. they seemed to be empty.
as i traced that problem a little closer i realized that my groupingfunction isnt called either.... i dont know wh y;(
hope that explains everything
thanks for help

Advanced data grid and grouping

This is probably a basic questions, so hopefully someone will
know the answer. I have an advanced data grid that works find a
follows:
<mx:AdvancedDataGrid id="adgReportList"
horizontalCenter="0"
y="28" width="485" height="500" dataProvider="{reports}">
<mx:columns>
<mx:AdvancedDataGridColumn headerText="Proposal Number"
dataField="PROPOSAL_NUMBER"/>
<mx:AdvancedDataGridColumn headerText="Report Title"
dataField="REPORT_TITLE"/>
<mx:AdvancedDataGridColumn headerText="Report Start Date"
dataField="PERIOD_BEGINING"/>
</mx:columns>
</mx:AdvancedDataGrid>
So the data coming back seems to be fine. But when I try to
group the data as follows, nothing shows:
<mx:AdvancedDataGrid id="adgReportList"
horizontalCenter="0"
y="28" width="485" height="500"
initialize="gc.refresh();">
<mx:dataProvider>
<mx:GroupingCollection id="gc" source="{reports}">
<mx:grouping>
<mx:Grouping>
<mx:GroupingField name="PROPOSAL_NUMBER" />
</mx:Grouping>
</mx:grouping>
</mx:GroupingCollection>
</mx:dataProvider>
<mx:columns>
<mx:AdvancedDataGridColumn headerText="Proposal Number"
dataField="PROPOSAL_NUMBER"/>
<mx:AdvancedDataGridColumn headerText="Report Title"
dataField="REPORT_TITLE"/>
<mx:AdvancedDataGridColumn headerText="Report Start Date"
dataField="PERIOD_BEGINING"/>
</mx:columns>
</mx:AdvancedDataGrid>
Thanks for any help.

Advanced Data Grid Sorting / Grouping Collection

Ok, basically here's the issue..
I have an advanced data grid with a tree view. It goes two
levels deep
so:
Report Type
|-------------------- Company
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
|-------------------- Company 2
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
Report Type 2
|-------------------- Company
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
|-------------------- Company 2
|--------------------------------------- Report 1
|--------------------------------------- Report 2
|--------------------------------------- Report 3
etc..
Report and Company are Nodes (folders) and are being sorted
alphabetically by default.
The individual reports (Report 1,2,3, etc..) are not being
sorted in any way that I can figure out. I need to sort them by
date, but no matter what I've tried I can't get it to work.
I tried a SortCompareFunction on the advancedDataGridColumn
that displays each report, and it works *IF* I click the header...
but if I dispatch the header_release event via AS3, nothing
happens.
I even set up a test:
dg.addEventListener(AdvancedDataGridEvent.HEADER_RELEASE,heard);
dg.dispatchEvent(
new AdvancedDataGridEvent
AdvancedDataGridEvent.HEADER_RELEASE,
false,
true,
0, // The zero-based index of the column to sort in the
DataGrid object's columns array.
null,
0,
null,
null,
0
function heard(e:Event) {
trace("I HEAR IT!");
trace(e.type);
I set that up on a button so I can dispatch the event with a
click. Every time I click the button, the header release event
listener goes off, but the actual advanceddatagrid remains
unchanged until I actually click on it's header..
Any help would be *GREATLY* appreciated... I've been stuck on
this problem for two days now :(

Advanced Data Grid in Action Script

ok so I am now generating an AdvancedDataGrid in Action script as I will have dynamically created columns based on specific user
My grid code looks like this
private function generateGrid():void
var clms:Array;
myADG.dataProvider=gridData;
myADG.width=
this.parentApplication.adgPanel.width-20;myADG.height=
this.parentApplication.adgPanel.height-39;myADG.visible=
true;myADG.x=0;
myADG.y=0;
myADG.designViewDataType=
"flat";myADG.horizontalScrollPolicy=
"on";myADG.verticalScrollPolicy=
"on";myADG.lockedColumnCount=6;
myADG.sortExpertMode=
true;myADG.headerWordWrap=
true;
My question is this, in my MXML Grid that preceded this I hand this line
click="{populateChildren(adg.selectedIndex)}"
How do I add this functionality to my new AS Advanced Data Grid??
populateChildren is a function that allows me to set the specific row as an object and share amongst other other modules based on the grid selection.
        private function populateChildren(loc:int):void
          selected = Object(gridData.getItemAt(loc));
          this.parentApplication.populateChart(selected);
Thanks in advance for any help.

The complete sample code contains 5 WebService calls that populate List collections views.
Given these services are not exposed externally, I can't see how that would be more helpful it would actually cause more errors.
But as usual with being new to Flex and AS I have found the root of the problem....ME    it's always something so silly and easily overlooked.
myADG.addEventListener(MouseEvent.CLICK,populateChildren());
should read:
myADG.addEventListener(MouseEvent.CLICK,populateChildren);
and for completeness my function needed to look like this
private function populateChildren(e:Event): void
selected = Object(gridData.getItemAt(myADG.selectedIndex));
this.parentApplication.populateChart(selected);
completely back to operational again.
Thanks for taking the time to look into this a bit, sorry for the trouble, but at least I will recognize that error, I had never seen it up till now.
Thanks again.

Advanced data grid and SummaryRow

Hello,
I've gotten the SummaryRow to work in AdvancedDataGrids in the past for performing certain functions like sum or average... but for this specific instance I want to do a summary row on non-numeric values (approved or rejected).
For instance... lets say I have a GroupingCollection in the advanced data grid and I want to group by department (this is a 1 to many with dept having 1 or more employees). At that grouped level I want to show either "approved" or "rejected"... how can i show this next to the grouped department (not as another group below the department)? See my screenshot below of my output and how I could achieve this.

Advanced Data Grid Refresh Issue

I'm using an advanced data grid which displays data in a tree structure format (parents and child nodes). The advanced data grid is a child component within a VBox and uses customized column renderers. I'm running into an issue where the advanced data grid is rebuilding (calling all the renderers again) whenever I move the mouse (focus) into the Advanced Data Grid component. The ADG component is binded to a data object. I'm expecting the ADG to rebuild when the data object it's binded to gets updated. In this case the bindable data object is not being updated. Why is the data grid rebuilding and is there a way to prevent this from occurring? I'm getting mouse over and mouse move events but they are not causing the ADG to rebuild.
Thanks for your help !!!

Can you give us a quick code sample where we can reproduce
this issue?
Thanks,
Swaroop

Hi,
while preparing internal table to be passed to ALV, you have to implement the logic for these scenarios.

Data grid within advanced data grid (Hiding and showing columns)

Hi,
I have a dta grid within advanced datagrid. When the row of advanced data grid is expanded, the datagrid opens up.
I want to control the columns of datagrid based on the value of a field in advanced data grid. I want to show all the columns of the datagrid if the field value of advanced data grid is "X" else I want to show only few columns of the data grid.
I will set the id for all the columns of the datagrid. Then I think I can write some code in a method to set the visibility of the columns and assign the function to item opening property of the advanced data grid.
Please give me some ideas.
Regards,
Mahee

Column formatting based on grouping data value- advanced data grid

Hello Everyone,
I am using advanced data grid to display hierarchial data nested upto depth 4. I have to color the leaf nodes conditionally based on the grouped column value.
Say for Eg.,
If the data is something like
Company
     Manager
          Jim          $4000
          John        $3000
     Accountant
          Smith     $2000
          Sam       $3000
I have to color Jim and John based on they being a manager. In other words, how do I get Manager and Company information for the leaf rows. The data is serial to start with and I am grouping it before displaying.
Please let me know how this could be done.
Thanks
Arun

Dumping data from an advanced data grid on the browser to microsoft Excel

I am building an app which enables a user to define a sql
query in a flex app on the browser. Once defined and the data
retrieved, the result set is then displayed in an advanced data
grid. The user then needs to be able to dump the data in the grid
to an Excel spreadsheet.
I'm wondering if anybody can point me to some possible
solutions for the Excel data dump part of this problem? Everything
else works.
Flex help does have one solution, but I'm getting an error
message that doesn't want to yield. I'd like to know if there are
other possibilities?
Thanks in advance. Jerry in Juneau, Alaska

What version are you using? If in 9i, you can use external tables. Otherwise, you will need either SQL loader, or to use ODBC. If you send me an example of your data, I can create a sample of each for you.

hi Srinivas,
Acually whenever i roll over the mouse on the column headers
of the Advanced Data Grid it hangs and throw this error.i am
getting a grouped data from data base and using the group
collection as data provider which has source property bound to
ArrayCollection.The problem comes only whenever we take the mouse
over the column headers it throws this error and hangs.
<mx:AdvancedDataGrid id="adg1" width="100%" height="100%"
wordWrap="true" >
<mx:dataProvider>
<mx:GroupingCollection id="gc" source="{this.ABC}"
>
<mx:Grouping>
<mx:GroupingField name="GroupingField"/>
</mx:Grouping>
</mx:GroupingCollection>
</mx:dataProvider>
<mx:columns>
<mx:AdvancedDataGridColumn dataField="Field1"
headerText="Field1" />
<mx:AdvancedDataGridColumn dataField="Field2"
headerText="Field2" sortable="true" />
<mx:AdvancedDataGridColumn dataField="Field3"
headerText="Field3" />
</mx:columns>
</mx:AdvancedDataGrid>
If move the mouse over the column headers the error is thrown
and the application hangs and the same code works fine with the
beta 2.
Thanks....

Advanced Data Grid Grouping per Level

I'm new to flex, i'm using the advanced data grid component and i need to do different grouping for each level in the tree,i want to do right click and select which drill down is relevent for the specific level.
how can i do it? the grouping seems to be for all the tree.

Advanced Data Grid Column Grouping

When using column grouping with the advanced data grid, is it
possible to ONLY show the AdvancedDataGridColumnGroup headerText
and not have the extra row for the AdvancedDataGridColumn
headerText? For instance, if a have a set of 3 columns with a
spanned group headerText of "manage", and the columns have buttons
with the text "edit", "move" and "delete", can I just omit the
secondary headings since the "edit|move|delete" text is there on
the buttons and redundant as a column heading?
