I have an ArrayCollection nested in another one. I need to sort the child collection by a field.
I tried the following code. It works fine for the parent collection, but does nothing for the child one.
// The Data
public class Data
{
public var value:String;
public var otherValue:String;
public var childrenData:ArrayCollection; // An array collection containing Data objects.
}

Is there a way to use some kind of encryption (md5, hash, etc...) to determine if two arraycollections are the same or not?
View 1 RepliesI've been kinda stuck in trying to organize data and bind them to a Repeater in one my applications.What I did at first, was to save an array of arrays, so that I could've accessed any value very easily. But then I realized that I needed to bind them to a Repeater, so I had to switch to an ArrayCollection of arrays. But the Binding issues weren't solved, since there are still arrays (not bindable) inside the ArrayCollection.Below an example of what I want to do:
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable] public var arr:ArrayCollection = new ArrayCollection(
[code]....
the traces show that the array size changes, but the repeater doesn't update.
How would I go about sorting an array of nested arrays, based on the contents of one of the nested arrays elements?
var nestedArray1:Array = new Array(0,0,1);
var nestedArray2:Array = new Array(0,0,9);
var nestedArray3:Array = new Array(0,0,7);

I am trying to make a class that would convert an arrayCollection to XML. I want to make it useful for all ArrayCollections.
My arraycollection looks like this....
newsDB.addItem( {
title: titleText.label,
clickURL: clickURL.text,
info: itemInfo.text,

I can access the AC with a for loop and arrayCollection.length, but how to I go deeper into the AC while making it work for any ArrayCollection? I could easily do dataSource[i].title but want to make this work for any arrayCollection passed into the class.
I need to create an arrayCollection as a copy of other arrayCollection. Then I need to change some data inside the copy, but when I do that the original arrayCollection changes as well. Is there a way to stop the changes in the original arrayCollection? For example I got: arrColOrig[0].someVar = 1

I have several datagrids with changing columns. For the text fields the datagrid's sort function neems to be making a case sensitive compare. eg. the following list sorted would look like this apples strawberries Autos Autos should be with apples but since the capital A is counted differently all capital letters come after. I've found a lot of information on setting a CASEINSENSITIVE flag, but I can't figure out where to do this. The best solution would be one where I can override the default behavior to be case insensitive for all my datagrids and all my compare functions.
View 3 RepliesHere are the strings this array can contain (in the correct order):
'recipients,' 'columnSelector,' 'headerImageLink,' 'title,' 'mainText,' 'text,' 'bodyImage'
Now, to sort them, I obviously don't want to do something like this:
if( a == 'columnSelector' && b == 'headerImageLink' ) return -1;
else if( a == 'columnSelector' && b == 'title' ) return -1;
else if( a == 'columnSelector' && b == 'mainText' ) return -1;
So that brings up an interesting thing. I know you can optimize the above some using something like this:
if( a == 'columnSelector' || a == 'bodyImage' ) return -1;
This would get the last two, but lately I have just wanted community input on issues I have had in the past. So the question is, what is the best way to write a custom sort, using a relatively random order (not alphabetical, etc)?

Is there any way in Flex where in we can sort an arraycollection based on strings .I have a dataprovider with strings like "Critical" "High" "Medium" "Low" where in I need to sort it in such a way that I need Critical to be displayed on the top and next High , Medium and Low follows.

View 1 RepliesI have a one comboBox that I fill as:
for (var key:String in values) {
conns.addItem(key);
}
After that I sorted my ComboBox as:
private function sortConnection():void {
var dataSortField:SortField = new SortField();
dataSortField.name = "data";
dataSortField.numeric = true;
var numericDataSort:Sort = new Sort();
numericDataSort.fields = [dataSortField];
conns.sort = numericDataSort;
conns.refresh();
}
And on finish I want to select item on my specific value in ComboBox. How can I do that? I try:
for (var ii:Number=0; ii<combo.rowCount; ii++) {
var item:String = combo.getChildAt(ii);
if (item == name) {
index = ii;
}}
But does not work. I do not know where I made mistake, and how I can select on specific item in my combobox.
I have a column with 4 fields named : a> Main, b> Forward c> Back d> Link, if I use pre-defined sorting of datagrid with the column names which will be alphabetically, then the order is c>Back b>Forward d> Link a> Main. But, I do not want to sort based on the alphabets. I prefer to sort by names of the column fields. i.e. somehow give priority to each individual column field names. Like pre-define my own order.
View 2 RepliesIn a Flex webapp, is there an easy way to go about applying a sort to the children of an XML element, based on the children's attributes? Example follows below:
XMLListCollection:
<a anotherProp="ABCDE">
<e prop="AB">1</element>
<e prop="BC">2</element>
</a><a anotherProp="FGEH">
<e prop="HF">3</element>
<e prop="AD">4</element>
<e prop="AC">5</element></a>
I would like to sort the <e> elements, within each <a> element separately, according to their "prop" attribute. My code for generating the array containing the <a> elements is along the lines of:
for each(var node:XML in initialInput:XMLListCollection){
if(node.localName()=="a"){
//I was hoping to be able to sort the <e> children of the node variable here
xmlListCollectionVar.addItem(node);
}}
At the end I would like the <a>'s to remain in their defined order, but their <e> children to be sorted based on the "prop" attribute. So far if I try:
node.children().sort=someSortVar
Where someSortVar has its fields set to:
SortFields("e.@prop",...)
I get an exception about a null value. Any way to convert the children list to XMLListCollection, sort it and integrate it back into the node variable?

I have a Advanced Datagrid with sorting. I think it is string sorting by default. But i need the sorting in number. How can i achieve the number sorting.for example: i have row numbers like 1 to 100 . i need number sorting like 1,10,100.
View 2 RepliesI 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.

I'm trying to provide some default sorting within the OLAPDataGrid component in Flex. There appears to be a dataCompareFunction on OLAPAttribute, but nothing I do seems to actually trigger calls to that method. Any suggestions around using this method or any others to provide sorting of the dimensions on OLAPDataGrid?
View 2 RepliesI have a list which displays votes cast on things in a descending order (=the dataprovider has a sort assigned). The elements have variable height, but there are not so many elements, so i do not need to use a virtual layout
My problem is that this list needs to be updated real-time and i want to make this happen with a nice animation. (e.g. if an item overtakes another by votes, then they swap places.) Anyone knows how to make this animation with Flex 4.5 (spark list)? Do i need to write a custom layout?

I have a DatagridColumn in flex with two names, TYPE and NAME. Now, when I am sorting a datagridcolumn, TYPE, it sorts the type using sortcomparefunction and gives the result which contains grouped and sorted order of elements. Ex. if I sort for type I get elements in pdf, doc, ppt in grouped order, but they are internally not sorted, ex: for the pdf part, I have elements such as:
TYPE NAME
pdf A1.pdf
pdf X2.pdf
pdf B1.pdf
Here the filetypes are sorted, but for a particular filetype, the elements are not, please notice that B1 occurs after X2, which should be sorted. Is there a way I can sort the second datagridcolumn after sorting the first one according to filetype extensions? I am using sortcomparefunction for sorting the elements according to type , which works fine. The signature is:
private function sortTheTypeColumn(itemA:Object, itemB:Object):int
I need to to a programmatic multi column sorting on the AdvancedDataGrid.The issue is, currently I am implementing paging on my grid. So, if I sort the data,only the perticular page is being sorted. So,I need to sort the entire list by the column criteria.I tried HeaderRelease event,but I guess it is of no use as I need to make a round trip call to the server to get the sorted data.Is there any way I can implement that.I also need to show the sort markers in the Column headers' right position, indicating the sort numbers and direction.
View 7 RepliesI extended the DataGridColumn because I wanted to include a custom itemToLabel function (to be able to show nested data in the DataGrid. See this question.
Anyways, it also needs a custom sorting function. So I have written the sorting function like so:
private function mySortCompareFunction(obj1:Object, obj2:Object):int{
var currentData1:Object = obj1;
var currentData2:Object = obj2;
[Code].....
Whenever I try to sort the column, I get the error "Error: Find criteria must contain at least one sort field value."
When I debug and step through each step, I see that the first few times, the function is being called correctly, but towards the end, this error occurs.
I am creating a Datagrid in AS3, and adding a sort function to a column. However, this sort function does never get called. Any ideas?

View 1 RepliesI'm creating a table that displays information from a MySQL database, I'm using foreignkeys all over the place to cross-reference data.
Basically I have a datagrid with a column named 'system.' The system is an int that represents the id of an object in another table. I've used lableFunction to cross-reference the two and rename the column. But now sorting doesn't work, I understand that you have to create a custom sorting function. I have tried cross-referencing the two tables again, but that takes ~30sec to sort 1200 rows. Now I'm just clueless as to what I should try next.
Is there any way to access the columns field label inside the sort function?
