Flex :: Can AdvancedDataGrid Automatically Detect AdvancedDataGridColumnGroup

Apr 13, 2011

I was trying the example from this link: Adobe Flex 4 * Creating column groups

The data is

import mx.collections.ArrayCollection;
[Bindable]
private var dpHierarchy:ArrayCollection = new ArrayCollection([
{Region:"Southwest", Territory:"Arizona",

[code]....

Using this code, AdvancedDataGrid automatically detects the column names and the data. But it fails to create nested columns for Revenues. it should create 2 sub-columns for it as Actual and Estimate, but it created only one column and the shows data as [object Object]Is there any way to make AdvancedDataGrid to create the nested columns automatically?

Actionscript 3 :: Automatically Detect When Files On A Directory Are Updated

Jul 27, 2010

I was wondering if it is possible to make and App capable of listening when the user "adds" new files to a directory.

Example:

The User opens up our Application. The user adds new files on the desktop (using the Microsoft Explorer). Our application automatically detects that new files have been added and executes a function or whatever.

Maybe, this could be done using a programming language like Visual Basic and open the executable with the NativeProcess api and listen for an stdOut event.

ActionScript 3.0 :: Automatically Detect Keyframes In Timeline From Runtime

Nov 6, 2010

I want to detect when the playhead hits a keyframe without having to put a function call on the keyframe. If it hits multiple keyframes at the same time (ie keyframes on different layers) I'd want to know that too. I'd happily parse some timeline data and find the keyframes myself, but I haven't been able to find out where this info can be found. Is there a Timeline Class I don't know of? I looked into xfl uncompressed format, and I could read the xml format to find the keyframes and where they're at, but thats a pre or post process, and obviously won't work with our runtime code. I want to know this inside runtime code from within flash player.

Flex :: Represent HTML Table Structure In Flex DataGrid Or AdvancedDataGrid?

Feb 12, 2012

I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.

Flex :: Flex Drag And Drop Between AdvancedDataGrid With Custom ItemRenderer

Feb 26, 2011

Flex :: AdvancedDatagrid MultipleSelection?

Jun 3, 2010

after multiple Selection in a advanced datagrid, I want to check if the clicked row, was already selected. Anyway my idea below (in the nested if clause I want to check if the newly clicked item's processing data is already in the added Array Collection) is not working, but I assume there must be a better way to differiante if an click was made on a already selected row.

model.processingData = out;
if (model.selectedIndices.length > 1){
//check if item already added

Flex :: Add Row Dynamically To AdvancedDataGrid?

Dec 14, 2010

I would like to add new row on the fly (runtime) to my AdvancedDataGrid.I can add it to the data model, but couldn't find a way to make the table render and show the new row.What i am seeking for is to create an effect of expandable item, where clicking on row will show "additional information" (like a drawer) and clicking on row expand button will reveal it's children.I saw examples of this for dataGrid (http:url...), but not for AdavancedDataGrid.Only way I found to do this is to add a new child and use openItem, but this cause the other children to be visible as well.

Flex :: Get Item From AdvancedDataGrid Given Index

Jul 7, 2009

I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is:

var oldSelectedIndex:int = this.selectedIndex;
var mouseOverIndex:int = this.calculateDropIndex(event);
this.selectedItem = mouseOverIndex;
var item:* = this.selectedItem;
this.selectedIndex = oldSelectedIndex;

The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?

Flex - AdvancedDataGrid ItemRenderer Ignored W/HierarchicalData?

Jun 13, 2011

I am using an AdvancedDataGrid with some hierarchical data. In the first column, I want to indicate whether or not the "name" field is editable by graying out the text for the "name" property of my objects. It's very odd, but when I set the AdvancedDataGridColumn's dataField property to "name", and have it in the first column, it seems to completely ignore my inline ItemRenderer. If I change the dataField property to something else, or change the column ordering so the Name column isn't first, everything suddenly works.

Let me know if any more code would help, but here is the simple ItemRenderer I'm trying to use in the first column:

Actionscript 3 :: Sorting In AdvancedDatagrid In Flex 3

Aug 25, 2010

I am using in-built sort functionality provided by AdvancedDatagrid.I have multiple columns and suppose I have 10 rows. All 10 rows have the same data in one column.If I sort on that column, then it sorts and the data in other columns which is different is also being sorted (reshuffled).My requirement is if I am sorting on a column with same data, it should not sort the data in other columns.To understand it better, check the link menioned below URL...In the above link mentioned, if you click on region column, other columns like territory or actual will change the values i.e. the rows gets reshuffled.This should not happen as we are sorting on a column which has same values. Does anybody know how this can be handled in Flex 3 for AdvancedDataGrid.

Jun 10, 2010

I'm using an AdvancedDataGrid without the header row (AdvancedDataGrid.showHeaders="false"), my AdvancedDataGrid has 2 columns, where the first one will show a hierarchical data (tree).The tree may be very long and very deep or may contain a long string in the node label so the user will not be able to see the whole vale of the tree node, I want to be able to resize the column using the vertical separator of the gris (the one displayed/separates between columns) or to be able to define a horizontal scroll bar only for the first column.
