Does anybody tried Dynamic column grouping using Hirarchical/tree data structure in Flex advanced datagrid ? is it possible to create a column header dynamically and so the datagrid column with using certain datafield using dataprovider dat.

View 1 RepliesI have some kind of UIComponent grouping which may look something like this with the classes "Group" and "Element". Groups can have children and children may be elements or groups again, basically similar to a file system or the str+g group function in several graphics programs. The simplest form of a group is a group with only children which are also the most low level groups in the tree.
The display hierarchy is already existant, i try to persist it to xml.
Group
- element
- Group
- element
- Group
-element
-element
- element
- element
I want to rebuild this structure in an xml-document for persistence. I know how to build an xml document in Flex but not how to (recursively) traverse this n-tree correctly. For getting only the child nodes one could make use of the following algorithm (pseudo code). But somehow I don't understand how to create the xml from this.
walkTree(group) {
children = node.getChildren
if(children != null) {
for(int i=0; i<children.length; i++) {
if(children[i].isGroup()) {
walkTree(group[i]);
} else {
trace(child);
}}}}
In Flex, using AdvancedDataGrid, I'm trying to achieve a drag and drop of one row's column data to another row's column or the same row but different column. Is this even possible? I've been googling for hours and all I can find are drag and drop whole columns just to rearrange their view order.
View 1 RepliesHow ever I want to be able to do this dynamically.
The usage in the project is to be able to represent any data from a database, with any number of possible groupings on the horizontal and vertical axis.
Could someone offer some guidance on the most efficient structure to get an XML return in order to build these kind's of pivots on the fly. All the examples I have seen are statically defined. What I would like to do is be able to have a structure for a return that could give any level of grouping and data return from a web service call.
The tool I'm building is a reporting tool, so users could drag any DB field into column or row potentially so the key thing is the ability to define and build "any structure" a user would want.
In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:
Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?

I noticed that mx:Tree inherits from List anad that treeListData supports a "columnIndex" property, but in my tests columnIndex is always 0. Does that mean I can actually add a column to a Tree? How?
What I'd like to do is have the end-nodes of the tree (the leafs) have "value" property that can be edited, and have that value appear in a fixed column. -- so column 1 is naviagation. column 2 is editing, basically.
I can always do it with an itemRenderer but I figured I'd ask you folks if there was a pre-existing solution already. Is there?
Also, is there a way to turn on horizontal scrolling? My data runs kinda deep in spots.
Is there a way to group context menu items into a tree like structure?Like the Quality in built in menu.You can test it on any flash that has the built in items enabled.Right Click -> Quality -> Low.Can you do the same with custom items?For example:Right Click -> Custom Options -> Option 1
View 5 RepliesI've asked this question before but had no answers... so here I go again I have a structure of objects: Top object A has as children (addChild children that is...) one or more objects B_1 to B_n. The B_n may in turn have one (1) associated object A' (Same type as top object, not displayed to begin with). When I click a B_n two things may happen:
1. If it has as associated object a A', put it on the stage (as child to B_n).
2. Otherwise it is a leaf and it does other things.
If '2' happens I want to collapse the tree, that is remove the top and all children of same type from being displayed. I thought a recursive approach should work:

As ArrayCollection in Flex is limited, I'm looking for a data-structure that something like LinkedHashSet in Java, LinkedHashSet maintains a doubly-linked list running through all of its entries,it defines the iteration ordering, which is the order in which elements were inserted into the set (insertion-order).But there is little information about Flex data-structure

How would I create a Tree component in Flex 3 that uses the groups as nodes, with the appropriate items listed under each node?
I have a requirement to filter the tree similar to that of flex builder-->preferences wizard tree.
My tree dataprovider is arraycollection of industries. Each industry has a list of sub industries and further, say upto depth 5.
So when we type in a string to filter, only the node having this string along with their parent hierarchy should be returned.
How can we implement this using flex?
I have component with Trees and I'm moving elements from one to another. I store data in dataProvider as XMLList with labelFiled="name" and itemRenderer as class, which expends one (thanks to that nodes and elements have checkboxes). I enabled moving mechanism between Trees just by enabling Tree's properties (dragEnabled="true" dragMoveEnabled="true" dropEnabled="true"). Problem occurs when I try to get data from dataProvider, which has only elements. To get data I use command:

group items in a DataGrid by an item property, fer example:Say you have a list of products, and the products belong to categories, like, Summer products, Winter products...is there anyway to group products in a DataGrid under separate headers? IE: Winter (all winter products follow) Summer (all summer products follow). I can already order by category, but instead I want to do this:
Winter Category
1. Winter Product 1
2. Winter Product 2
3. Winter Product 3

Do it need to create a DataGrid for categories and nested DataGrids for products per Category? Or is there some built-in way of grouping within a DataGrid?
I've got a DataGrid in my mobile application (I know, I know but there's currently not other solution for this), that numeric values. Depending on the value of a cell, the text gets colored. My big issue is that this doesn't work very for more than about 5 rows of data. I reckon the issue is that the set text function (in which I format the color) can't keep up with the amount of cell changes and formats the text based on the last updated cell of the row.I thought about a column item renderer so that the renderer only gets the value for that column, and not the whole data of the row.
Just for reference, this is my current item renderer (again, this works fine for few rows, for 5+ of fast changing data, this doesn't work any more, cells get formatted even though their data hasn't changed).[code]I just double-checked and have to revert my previous statement. A single row works fine, the second row already messes up the color formatting though. It seems as if the datagrid somehow throws together the values.
Doing the color formatting in the set data method shows the exact same effect;[code]My assumption about the grid messing up the ItemRenderer's data seems to be correct.A simple trace in the set data method (trace("old: " + _oldVal + "new : " + value[column.dataField]);) revealed that somehow, values of the next grid row (in case there are 2) get used as well as _oldVal gets the old value of the next row.
I have an actionscript-instantiated component in a containment hierarchy; it extends ComboBox, but it's instantiated dynamically--you never know when you're going to need it. Somewhere up in its containment hierarchy, there's a thing which extends NavigatorContent which logically is the right place to put the valid values for said combo box. What's the canonical way for that child component to get a reference to that set of valid values?
View 2 RepliesI'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?
