Creating AdvancedDataGrid in AS

ok I'll try to make this clear as possible.
I've decided to create my AdvancedDataGrid in Actionscript becuase the users want to be able to create columns dynamically.
My service returns a ListCollectionView of object proxies.
Which I then cast into an ArrayCollection of Objects.
private var myADG:AdvancedDataGrid = new AdvancedDataGrid;
private function generateGrid():void{
var clms:Array;
myADG.dataProvider=gridData;
myADG.percentWidth=100;
myADG.percentHeight=100;
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;
clms = myADG.columns;
//loop to add columns
var adgc:AdvancedDataGridColumn = new AdvancedDataGridColumn();
adgc.headerText=
"Sales Order"adgc.dataField=myADG.dataProvider.pdNO; <-----I have no idea what should be, pdNO is a variable from the list of objects that are returned.
adgc.width=72
adgc.visible=
true;
clms.push(adgc);
//end loop
myADG.columns=clms;
pan1.addChild(myADG);
I'm a little unclear how to capture the columns from the existing data set (I am just trying to build the grid as is, none of the dynamic stuff yet).
I had this all in MXML before and it was fairly easy to bind the dataField based on each Object property. But how do I do that now, yes i know it needs to be a loop through an array, but I was just trying to add one column for now to see if I can get it to work.
Thanks in advance, I hope that's clear.

Nevermind, I'm an idiot. I forgot to actually call the method to generate the grid. Sorry folks.
It's working like it should.

Hi,
I see that this question is unanswerd for a while, and I came across it when I encountered the same problem.
If you want to acheive the tootip for each CELL in the datagrid then you can use the ItemOver listener
setup the listener:
dg.addEventListener(ListEvent.ITEM_ROLL_OVER , itemOver);
define itemOver:
public function itemOver(event:ListEvent):void
                var toolTipText:String                = (AdvancedDataGridItemRenderer)(event.itemRenderer).text; //only if you want to show the text in the cell itself as the tooltip
                (AdvancedDataGridItemRenderer)(event.itemRenderer).toolTip    = toolTipText;
and thats all you have to do.

How to create summaryRow for HeirarchicalData in AdvancedDataGrid?

Hi,
Am working with AdvancedDatagrid..
Following arraycollection i used as Heirarchical Data for
Dataprovider of ADG.
[AS]private static var dpHierarchy:ArrayCollection = new
ArrayCollection([
{Region:"Demand",
children: [
{Region:"Forecast",
children: [
{Region:"Gross Forecast",
children: [{Region:"Open Forecast"}]},
{Region:"Net Forecast", value:"20"}]},
{Region:"Actual",
children: [
{Region:"Sales Order",
children: [
{Region:"Collaboration",
children: [
{Region:"Negotiation", value:"100"},
{Region:"Authorization", value:"200"},
{Region:"Published", value:"300"},
{Region:"Open", value:"400"}]
}]);[/AS]
output looks like this...
>Demand
>Forecast
>Gross Forecast
-Net Forecast 20
>Actual
>Sales Order
>Collaboration
-Negotiation 100
-Authorization 200
-Published 300
Open 400
Now what am looking for is need to get the summaryRow at
parent level...Each and every parent level should have SUM of its
child.
i need something like this...
>Demand
1020
>Forecast
1020
>Gross Forecast
1020
-Net Forecast 20
>Actual
1000
>Sales Order
1000
>Collaboration
600
-Negotiation 100
-Authorization 200
-Published 300
Open 400
I created ADG using actionscript. I didnt used MXML tags.
Now i need to create SummaryRow using Action script only.
Any idea how to do this??
Thanks in Advance

AdvancedDataGrid - create Array (cfquery) with children for hierarchical data set

I'm trying to create an AdvancedDataGrid with a hierarchical
data set as shown below. The problem that I am having is how to
call the data from a ColdFusion remote call and not an
ArrayCollection inside of the Flex app (as below). I'm guessing
that the problem is with the CFC that I've created which builds an
array with children. I assume that the structure of the children is
the issue. Any thoughts?
Flex App without Remoting:

<cfset aDetails

</cfloop>
<cfreturn aPackages>

I had similar problems attempting to create an Array of
Arrays in a CFC, so I created two differents scripts - one in CF
and one in Flex - to build Hierarchical Data from a query result.
The script in CF builds an Hierarchical XML document which is then
easily accepted as HIerarchical Data in Flex. The script in Flex
loops over the query Object that is returned as an Array
Collection. It took me so long to create the XML script, and I now
regret it, since it is not easy to maintain and keep dynamic.
However, it only took me a short while to build this ActionScript
logic, which I quite like now (though it is not [
yet ] dynamic, and currently only handles two levels of
Hierarchy):
(this is the main part of my WebService result handler)....
// Create a new Array Collection to store the Hierarchical
Data from the WebService Result
var categories:ArrayCollection = new ArrayCollection();
// Create an Object variable to store the parent-level
objects
var category:Object;
// Create an Object variable to store the child-level
objects
var subCategory:Object;
// Loop through each Object in the WebService Result
for each (var object:Object in results)
// Create a new Array Collection as a copy of the Array
Collection of Hierarchical Data
var thisCategory:ArrayCollection = new
ArrayCollection(categories.toArray());
// Create a new instance of the Filter Function Class
var filterFunction:FilterFunction = new FilterFunction();
// Create Filter on the Array Collection to return only
those records with the specified Category Name
thisCategory.filterFunction =
filterFunction.NameValueFilter("NAMETXT", object["CATNAMETXT"]);
// Refresh the Array Collection to apply the Filter
thisCategory.refresh();
// If the Array Collection has records, the Category Name
exists, so use the one Object in the Collection to add Children to
if (thisCategory.length)
category = thisCategory.getItemAt(0);
// If the Array Collection has no records, the Category Name
does not exist, so create a new Object
else
// Create a new parent-level Object
category = new Object();
// Create and set the Name property of the parent-level
Object
category["NAMETXT"] = object["CATNAMETXT"];
// Create a Children property as a new Array
category["children"] = new Array();
// Add the parent-level Object to the Array Collection
categories.addItem(category);
// Create a new child-level Object as a copy of the Object
in the WebService Result
subCategory = object;
// Create and set the Name property of the child-level
Object
subCategory["NAMETXT"] = object["SUBCATNAMETXT"];
// Add the child-level Object to the Array of Children on
the parent-level Object
category["children"].push(subCategory);
// Convert the Array Collection to a Hierarchical Data
Object and use it as the Data Provider for the Advanced Data Grid
advancedDataGrid.dataProvider = new
HierarchicalData(categories);

Solved this issue by using mx:rendererProviders element for my AdvancedGrid. Using the depth parameter gives me the ability to hide the itemRenderer for the Grouped rows.

How to change the order of groups in AdvancedDataGrid

Hello,
I have a dataset similar to the following:
Region   Sales
======   ======
North     10
North     15
South     5
East      20
West      5
West      4
West      3
I'd like to group by Region and sort the groups by the Sales subtotal for each group. I already have the data grouped correctly using GroupingCollection2. How can I sort the groups by the sales subtotal (it sorts by region name by default)? I've seen some posts that talk about creating a custom groupingObjectFunction and applying a group sort. But I'm still confused. Can someone give me some pointers on how to achieve this?
So ideally, the AdvancedDataGrid would end up looking like this with the regions sorted by sales subtotal;
Region    Sales
======    ======
North
          10
          15
subtotal 45
East
          20
subtotal 20
West
          5
          4
          3
subtotal 12
South
          5
subtotal 5

Thanks, I looked at that earlier but it doesn't contain the solution I was hoping to find.
I ended up not using GroupingCollection. I think GroupingCollection is cool, but it isn't really customizable to the extent I need.
I just ended up transforming my data into a hierarchical form that could be used directly by AdvancedDataGrid. At the top level of my hierarchy, I have the detail txn groups, subtotal groups, and grand total groups. To sort the groups, I use custom SortFields. So, for example, if I want to sort by group name, I add a SortField for the groupName attribute. Both the Detail Group and the Subtotal Group share the same group name. Then I add a SortField for a summaryRow attribute. Only the subtotal group has that attribute. This ensures that the Detail Group is always followed by the associated Subtotal Group after sorting. I store my groups in an XMLListCollection and then set the sort attribute, then call refresh().
Not ideal, but it works. If my requirements were more complex, perhaps my approach wouldn't have worked as well. But as it stands it works well and has good performance.
I was hoping that ADG could handle this kind of sorting for me, but after looking at the source code, it seems like this is not possible without implementing my own custom GroupingCollection class and possibly other supporting classes.
One key thing to note is that clicking the column header to sort within groups works fine. However, if you then attempt to sort at the group level, ADG hangs while trying to refresh itself. The trick is to assign the dataProvider.sort attribute to a temporary variable, then set it to null (this sort variable contains the ADG column sorts that the user clicked). Apply your group level sort and then reapply the dataProvider.sort attribute.

Dynamic Hyperlinks in DataGrid/AdvancedDataGrid

Forgive me, but when the web was build around hyperlinked text, it should be easier to create hyperlinks in a Rich INTERNET Application.
Ok - enough griping. I do have a legit question:
For historical reasons, I have to construct hyperlinks from a number of parameters passed in the URL (aka GET params). Since I write reporting systems, those hyperlinks usually have to appear in a table of some sort: a DataGrid or AdvancedDataGrid.
My typical code looks something like this:
<mx:Application blah=blah>
     <mx:Script>
          <![CDATA[
          ]]>
     </mx:Script>
     <mx:HTTPService id="getStuff" method="get" url="http://www.example.com/getData.php" result="processServerData(event)"/>
     <mx:AdvancedDataGrid blah=blah>
          <mx:columns>
               <mx:AdvancedDataGridColumn blah=blah itemRenderer="ADGcustomItemRenderer"/>
          </mx:columns>
     </mx:AdvancedDataGrid>
</mx:Application>

OK, I didn't mean to post that yet. Why can't I edit my post?
Anyways...
<mx:Application blah=blah>
     <mx:Script>
          <![CDATA[
               import a.bunch.of.stuff
               protected function onInitialize():void {
                    getStuff.send();
          ]]>
     </mx:Script>
     <mx:HTTPService id="getStuff" method="get" url="http://www.example.com/getData.php" result="processServerData(event)"/>
     <mx:AdvancedDataGrid blah=blah>
          <mx:columns>
               <mx:AdvancedDataGridColumn blah=blah dataField="dataFieldName" itemRenderer="ADGcustomItemRenderer"/>
          </mx:columns>
     </mx:AdvancedDataGrid>
</mx:Application>
ADGcustomItemRenderer.mxml
<mx:Canvas blah=blah>
     <mx:Script>
          <![CDATA[
               import mx.controls.dataGridClasses.DataGridColumn;
            [Bindable] protected var myURL :String;
            override public function set data(value:Object):void {
                    myURL = '<a href="http://www.example.com/dosomething.php?dept_num=00000&vendor='+value['dataFieldName']+'" target="_blank">'+value['VendorName']+'</a>';
          ]]>
     </mx:Script>
     <mx:Text htmlText="{myURLl}" height="100%" width="100%" />
</mx:Canvas>
Notice the dept_num? I need to pass that data to the itemRender, since it can change from page to page (though not row by row) in addition to the column-specific data passed via the "value" object. How can I access that data from the custom itemRenderer?
Thanks

Add Custom Right click menu on editable AdvancedDataGrid

Hi,
I have an AdvancedDataGrid whose editable property is set to true and selectionmode is multipleCells.
Is it possible to display custom right click menu when i right click on any cell? Am getting only the
default menu items (Cut, Copy, Paste, Select All). Am using ContextMenu and ContextMenuItem class
for creating the custom right click menu. The same code is working in Flex and not in AIR. Do we have
to use NativeMenu in Adobe AIR? Please help. Attaching sample of my code.
<mx:Script>
<![CDATA[
[Bindable]
private var cMenu:ContextMenu;
public function createContextMenu():void {
          cMenu =
new ContextMenu();     cMenu.hideBuiltInItems();
     cMenu.addEventListener(ContextMenuEvent.MENU_SELECT, contextMenu_menuSelect);
     var cMenuItemCopy:ContextMenuItem = new ContextMenuItem("Copy Data");     cMenuItemCopy.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, contextMenuItemSelect_Copy);
     var cMenuItemPaste:ContextMenuItem = new ContextMenuItem("Paste Data");     cMenuItemPaste.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, contextMenuItemSelect_Paste);
     cMenu.customItems.push(cMenuItemCopy);     cMenu.customItems.push(cMenuItemPaste);
this.contextMenu = cMenu;
private
function contextMenu_menuSelect(event:ContextMenuEvent):void { }
private function contextMenuItemSelect_Copy(event:ContextMenuEvent):void {
     copy(event);
private function contextMenuItemSelect_Paste(event:ContextMenuEvent):void {
     paste(event);
]]>
</mx:Script><mx:AdvancedDataGrid width="100%" height="72%" id="dProvider" creationComplete="init()"
      editable="true" itemEditBeginning="checkIfAllowed(event)" itemEditEnd="onEditEnd(event)"
      selectionMode="multipleCells" itemRenderer="renderer.ColorForDashBoard" contextMenu="{cMenu}"/ >

I have same issue too. Can any one help
Thanks

Display restriction in AdvancedDataGrid

Hi All,
I am using AdvancedDataGrid for displaying information. I set
"variableRowHeight= true", so I cannot set the rowCount property I
guess.
Now my Grid is displaying information beyond the pageheight
ie., its adding number of rows as many as possible. But what I
actually want is that, before displaying each row int he grid, it
should check whether the new row is having enough display area left
in the screen to accommodate, then only it should add the row and
display the information.
so kindly give your suggestion to acheive that.
Thanks
Suren

AdvancedDatagrid Grouping question

Getting the hang of this AdvancedDataGrid control. I think it has a lot of potential but I just cant figure out how to do one thing. As you can see from the picture I am grouping by Section and then SubSection. The problem is when there is no subsection data value the items are grouped into a blank folder. Kind of tacky. I wrote this groupLabelingFunction:
private function groupLabelHandler(data:Object, depth:int):String {
                var grp:IGroupingCollection = diagnosesGrid.dataProvider.source as GroupingCollection;
                var grpLabelProperty:String = grp.grouping.label;
                return (data[grpLabelProperty] == null || data[grpLabelProperty] == "") ? "(No Subsection)" : data[grpLabelProperty];
And that works great. Instead of a blank folder the folder is titled (No Subsection) however, my boss would instead like those items in that folder to appear in the root of the Section folder. Is there a way to pull them out or get it to ignore the subgrouping when the value is blank?
Thanks,
KC

Hi Guys
Thanks for your help
Panda - I think I know what you are meaning but having the lastname in the group header will provide the formatting for the report we require. We really want to show the format as follows
Client Firstname Client Lastname    Hour Total
Jim                     Smith                        8
Steven                Black                        10
Would having the lastname in the group header still allow me to keep the above format?
Travis - I have created the formula you have said however I'm not sure what you mean by "create a group from this formula" can you explain a bit more, sorry I am quite new to crystal reports.
Thanks

How to merge cells in AdvancedDatagrid?

Hi All,
I am using advanced datagrid in my project to show hierarchical data.
we have a requirement to merge related cells so that it will look like below (just like row span in html table)
1
1.1
1.2
1.3
2
2.1
2.2
2.3
For column header it can be done by AdvancedDataGridColumGroup. So there must be some solution to merge cells to create the same effect for row.
Anyone has any idea on how to achieve this?
Thanks!!!

Check out the rendererProviders property on AdvancedDataGrid. It lets you dynamicaly determine what renderer to use at runtime based on the data being rendered. It takes a list of AdvancedDataGridRenderer instances, and those instnces have properties for colSpan and rowSpan.

Can I use AdvancedDatagrid in an opensource project?

I have a student Flex Builder education license. Can I use
AdvancedDatagrid in an opensource project?

I am new to Swing, and I would like to know, if is
possible create a application using Swing as view tier
in a J2EE(EJB) project? Yes, it is entirely possible, they are usually called Rich Clients (as in functionality) and may or may not use RMI/EJB. They typically also include the Controller (from MVC pattern) in the Client. The EJB represent the model, remember that the MVC is a Client Server Pattern, not an J2EE pattern.
Did anybody create one yet?Yes, the idea is not uncommon, you can read a more here:
http://www.google.co.uk/search?hl=en&ie=ISO-8859-1&q=Rich+Swing+Java+Client&btnG=Google+Search&meta=
How many J2EE projects do you know which Swing is used
as view tier? Using Swing is so much more complicate
than a ordinary output in HTML? No, just different. Instead of doing each action in your Swing App, use the normal EJB method.
Is there a open source project uses this approach?Probably, checkout the list of Google links above.

AdvancedDatagrid scroll bar buttons

Can I make a copy of an AdvancedDataGrid Item Renderer?

I have manual drag-and-drop functionality built in to my
AdvancedDataGrid (ADG). Right now, I am building my own custom drag
proxy using a Container instance and grabbing the text to use from
the "selectedItem" property. This creates a suitable image to drag.
However, what I'd really like to do is have the drag proxy look
exactly like the item renderer of the item I'm dragging. I don't
want the whole row, though, only one cell - that's why I can't use
the ADG's "dragImage" property. When I run the code below to
attempt to make a copy of the itemRenderer instance, the
itemRenderer in the ADG for the source item is cleared out - the
label disappears. Is there some way to make just a "copy" of the
itemRenderer instance, so that it doesn't disappear from the
ADG?

The itemRenderer is made by the ADG using the ClassFactory of
the
itemRenderer class.
I think you can search for the appropriate ClassFactory for
that column,
then make a new renderer from that Factory. Set its data
and/or listData to
the same as the existing renderer.
This might look something like this:
var factory:IFactory;
var renderer:IListItemRenderer;
//populate factory with the appropriate renderer factory
//you need to do this part
factory=?;
renderer = factory.getInstance();
renderer.data=selectedItemRenderer.data;
renderer.listData=selectedItemRenderer.listData;
proxyBox.addChild(DisplayObject(renderer));
You also might find that you can shortcut this by using new
(getDefinitionByName(selectedItemRenderer.className)) instead
of the
factory.

How create grouped column in DataGrid ?

Hi all,
I can create grouped column in AdvancedDataGrid. So in DataGrid, how I create grouped column ?
Thanks.

I have a problem that no anyone can help me to now. Sometime, I think that it's bug of ADG.
My goal same as from http://blogs.adobe.com/aharui/BlinkWhenChanged/dg.swf . But if I use ADG and with a scroll ! And when scroll up or down background color change not right.
It's a big problem ! Yep, when I use ADG, I can create group columns but ADG, I can't !
Is there any ways for me?
