I'm trying to update a combobox/datagrid sorter that came from flex3 to a flex4 version but I keep getting an error that my newbie brain is not processing. The error is "1067: Implicit coercion of a value of type Array to an unrelated type mx.collections:IList."

I'am trying to create a Flex Application where users can select courses from a combo box based on the department that offers the course. The combo box has an XML variable as its data provider and has the different departments listed. When a user selects the department from the combo box the courses offered for that department should automatically update (show up) in the data grid under their respective columns. What it needs to do is retrieve the XML for the selected department and then set the data provider for the srcgrid accordingly. I am having a lot of trouble with things displaying correctly in the data grid. The course should be under Course ID, course name under Name, etc...

well, I have a combobox which I have bind his selectedItem property to a value object object, like this
<fx:Binding source="styles_cb.selectedItem.toString()" destination="_uniform.style"/>
<fx:Declarations>
<fx:XML id="config_xml" xmlns="" source="config.xml" />
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:ComboBox x="66.15" y="63.85" editable="false" id="styles_cb" dataProvider="{config_xml.styles.style}" />
the value object is a custom class with some setters and getters, and I want to set a property based of the value of the selectedItem of the combo, so inside the value object I have something like this
[Bindable]
public function set style(value:String):void
{
_style = value;
trace(value);
}
my problem is that each time I change the combobox selection which in fact change the style property of the value object it does it 3 times, if I trace the value of the setter it actually do the trace 3 times, why?? how can I avoid this? I'm doing something wrong? or there is a better way to do it,

I have a data grid that has ComboBoxes in two of its columns.
What I need to do is get the values of those bombo boxes when a user highlights the row of the grid NOT when the user uses the comboBox. I understand how to pull the values out once the change handler is invoked on the comboBox, but I'm not seeing a way to get at the comboBoxes that belong to the currently highlighted gridRow.
I'm sure it's really straight forward, but I'm just not able to find any reference on how it's done.
I have a DataGrid with a ComboBox as an ItemRenderer for one of my columns. When the user selects a row, I want to get the ComboBox's selected value for the selected row.
EDIT: I should have mentioned that the dataField2_Array property in myData is actually an Array is the dataProvider for the ComboBox. Each object in myData could have completely different values in that Array so the ComboBox in each row of the DataGrid could have completely different options to pick from.Some sample code:
<mx:DataGrid id="myGrid"
dataProvider="{myData}">
<mx:columns>[code].....
I have datagrid binded with data acquired from web service which, as you may suspectretrieves data from some db. Datagrid has some editable columns and I want to update db through appropriate web service call without adding button "Update" as a last column in datagrid.
View 1 RepliesI have a custom <mx:DataGrid /> that is updated with data from a ColdFusion server every 60 seconds. I've noticed that every time the DataGrid updates and redraws the scroll position is reset to the top.
Is there a way I can preserve the scroll position for my DataGrid?
How can I filter a datagrid based on the value in the combo box? Can anyone show me some good examples on it?
In my application, I already filter a datagrid based on the text entered by the user. I check if the entered string matches the column entry of the datagrid and if a match is found,the filterFunction on the dataprovider is called.
This is that code:
<mx:FormItem direction="horizontal">
<mx:ComboBox id="searchCriteria1" dataProvider="{criteriaDP1}" change="searchFunction()"/>
<mx:TextInput id="search" change="searchFunction()"/>
[Code]....
searchCriteria is the comboBox,where I have the items, "ALL","HIGH"...I have two rows with value "high" and I get the Alert "yes" for two times only.. But in the data grid all the four rows are displayed.
In my Flex Project using Cairngorm, I have a model that stores a bindable ArrayCollection displayed by a DataGrid. My problem occurs when the model is updated by the responder (from a Java service, after an "update" event), because the focus located in a cell of the DataGrid is lost (the scroll position il also lost). So, I retrieve the position before the update, with DataGridEvent.ITEM_FOCUS_IN event :
myModel.focusedCell.rowIndex = e.rowIndex;
myModel.focusedCell.columnIndex = e.columnIndex;
But, from where restore these parameters ? How to trigger this update only when the model is updated ?
It might sound like a trivial question but how can I show progress bars, when datagrids and other components that "talk" to web services, update their data providers
View 1 RepliesI have a Datagrid that is being populated by an ArrayCollection (rows) of Arrays (columns).I need to update the headerText of each column based on a List that will correspond with the total number of items within each array in the arraycollection.

I know that I can set a listener in the List and update the headerText using (matrixDatagrid.columns[i] as DataGridColumn).headerText but I am looking for a cleaner solution.

I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.
In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.
If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?
I can always make another loop and array collection for the Name, but I was wondering if there were a better way.

I know AS3Commons-collection framework is a good one, but it can't use in ComboBox, recently.I try to use LinkedSet data structure to retrieve and store data in ComboBox, any one can help me?
View 1 RepliesI have a datagrid.In this datagrid I have a combobox item editor. This datagrid also has multiple columns where a user inputs numbers in each column. These numbers are then calculated by formula where the sum is posted in the "total" column. In this combobox there are two options for the user to choose from and each option has a different formula for calculating the inputted numbers. What I want is for when a user chooses "option 1" one formula is used to do the calculation, when "option 2" is chosen by the user then formula two is used to the calculation.Here's an example:
Combobox Option 1 (formula 1) is chosen by user = (Column2 - Column1) x column3 = "total" column
Combobox Option 2 (formula 2) is chosen by user = (Column1 - Column2) x column3 ="total" column
I realize you would use a conditional such as "if else" statement, but im just not sure how to do it. I've been trying to implement this for a while with no success.
OK I have an AdvancedDataGrid. The data I feed it is XML that looks like this:

<stat associate="John Doe" date="09-07-08" customer ="Amanda Jones"/>
<stat associate="John Doe" date="09-07-09" customer ="Henry Scott"/>
But I am grouping by associate so it ends up looking like a tree like this:

How can i update multiple cells of the same row changing the value of a single cell of the same row ??
Example: id, height, weight, fat percentage, corporal mass. When i change one of the values in a row (except id of course) the corporal mass cell value must change using a formula like: (height/weight2)*fat percentage*100. Is this posible with Datagrid or AdvancedDatagrid in Flex ??
I tried using custom item renders and inserting actionscript code inside the datagrid with no good result.
Im working with a flex application that pulls data from a java class file using message handler event. The received message string is added to ArrayCollection. The string consists of codeID and other values related to codeID. Had displayed the detail in a datagrid. The codeID is randomly generated and is pushed to flex for every second. Now, the problem is, I needa update the datagrid cell values, for instance, if i have pushed codeID's of (0001,0007,0005,0003) to the front end, that displays the corresponding values of each codeID in the datagrid, second instance of (0001) should update records in the existing row of (0001). I tried to check the existence of codeID in ArrayCollection using search algorithm, but dont know how to proceed further.
View 1 RepliesI have a component A in my flex project where people can vote for their favourite artist. Someone "likes" an artist, it get's updated in my database. There is also a component B that shows a chart of the most liked artists. I call the data from the database on creationcomplete in Flex. The problem is that when a person first votes on an artist, it will not be visible in the datagrid untill the user reloads the main page (?) or reopens the entire application. So i was wondering how i can update the datagrid everytime someone adds a vote to my database. I'm now using an update button, but that's not very user friendly of course.

I have a very strange problem in a Flex 3.4 Datagrid. One of the columns is a ComboBox - I have my own custom renderer for the ComboBox. I use it to select my data and then make a "save" to the db. Upon return the comboBox loses its value. Even stranger is that when I scroll the datagrid area to the left (by moving scrollbar right) - the values in the ComboBox change!! When I scroll the datagrid right (by moving the scrollbar left) - the values in the ComboBox don't change.

I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.
recently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)

Shown in that image is my combobox, populated with data. The problem is that if I set the selectedIndex of the combobox to whatever value is in the corresponding cell, the user can no longer change the value of the combobox. What I mean is, you click on the combobox, a list appears to select from, but you can not select any item in that list.
Here's my code:

I'm creating Datagrid dynamically and giving each row's first column a custom checkbox cellrenderer as noted here: [URL]. I have added an ITEM_CLICK event listener to the datagrid as such:
Code: datagrid.addEventListener(ListEvent.ITEM_CLICK, ToggleCheckBox); However, for the life of me I cannot figure out A) how to target the CheckBox specifically, B) how to toggle its' selected value, and C) how to finally update the datagrid view to reflect the toggled option.
Code:
private function ToggleCheckBox(e:ListEvent) {
// do some magic
}
