ActionScript 3.0 :: ComboBox As CellRenderer For DataGrid?
Mar 23, 2009
The following code is the cell renderer for for a ComboBox in a DataGridColumn. It works fine when setting the comboBox's data in the constructor. There's a problem using the red code below. If the DataGrid row is not already selected the dropdown list appears but is empty.Any ideas? If the row is not already selected, the selectedItem is being set causing a STATE invalidation after the list a created. I'm not sure how to prevent this.
Code:
package
{

I need to put a combobox in a column of a datagrid. The user just need to select a value from the existing combox items.I know I need to use a custom cellrenderer. Please see my current attempt below.This attempt successfully inserts a combobox into the datagrid, BUT without any data in the combobox. In fact, when I click on the combobox in the datagrid, it is the same as a normal combobox on the stage without a dataProvider. In other words, it doesn't even open.Thus, I need to know how to modify my cellrenderer to correctly add the data to the combo and accept changes made by the user when selecting a value from the combobox.[code]

which I can't seem to solve. I'm using a cellRenderer to display icons in a dataGrid. All works fine until I type in the command myDg.hScrollPolicy = "auto". Once I issue that command, the icons stop displaying. If I remove that line, all works well once more.

I have a datagrid whose data keeps updating quite frequently.On every update, I need to change the cell color of only those cells whose data has changed.That too, if the updated value is less than the older value then the cell color should change to RED else, GREEN.
I have tried using labelFunction, cellrenderer, etc. But to no avail.By no means, I am able to access the present data in the cells to compare it with the new data.I have added the sample classes in the attachment. To get them to work, just create an fla with a DataGrid & a Button components in its library & mention 'del' as its document class.Just run the fla & click on the two buttons on stage to see the values in the price column changing.

I am attempting to combine two AS files that are acting as cellRenderers individually but not simultaneously for cells in a datagrid in a Flash document I have created. The first styles the cells to have alternating row colors and the second allows for non-text content to be rendered. The issue is whenever I attempt to combine them the document reports errors with "super" and "override" among others.

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 am trying to put a combobox inside a datagrid. I managed to get it this far:
[URL]
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:
Code:
package
{
import fl.controls.listClasses.ICellRenderer;

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.

I am trying to populate a datagrid based on a value selected from a combobox. The data comes from a xml file, which looks something like this,[code]The user can list data in the datagrid based on either "media" and "region." For example, the user should be able to choose "Europe" from the combobox and list "only" media having "Europe" in the region tags. In this case, if the user chooses "Europe" from the Combobox only one listing (rammstein) will be seen in the Datagrid.However, it doesn't work. I get a blank datagrid. Loading data into the datagrid is not the problem, because if I just use a straight For loop with no conditions I fill the datagrid no problem. The problem comes up when I try to control what data get listed in the datagrid based on selected value in the combobox.[code]

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 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.

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...

I have a data grid with an Combobox itemRenderer in it. What I have is a grid with a person id and person name (more stuff in grid but I am struggling with this). In the person name column I have an combobox with all the people on then system's names and id's. What I want to do is when I select a person in the combobox I want the combobox to populate the person name fields (which it does) but I also want to pull out the person id from the combobox and populate the person id column in the data grid as well.

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.

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)

I'm used to item renderers in Flex but inexperienced with Flash AS3 components.I want to create a List that renderers items like this:
1) a slider
2) a couple of text fields that my designer can place and style as he likes
It's a survey form. I expect to grab the _listData.owner and dispatch the user inputs and bubble them up to the form.
1) drag a list onto the stage
2) create a symbol in the library with the base class of com.blah.skins.renderers.SurveyItemRenderer
3) Export this class as SurveyItemRenderer
4) set the list's cellRenderer style to SurveyItem renderer
5) give the list data to show
I tried using CellRenderer, but the class seems to reject being associated with a symbol (and I could not find any examples of CellRenderer being used that way), so SurveyItemRenderer implements ICellRenderer.When I run it, other library symbols and graphics shows up in the renderer--WITH THE EXCEPTION of the slider. Other Flash components that I put on the stage do not show up either, until you roll over (Button), or if they have text in the them (Label). Slider never shows up.
Components will show up on the stage, just not in the SurveyItemRenderer. WHY NOT? I feel like I'm missing something basic. Here is the class, minimal because I'm still testing:
Code:
public class SurveyItemRenderer extends MovieClip implements ICellRenderer
{
protected var _listData:ListData;
protected var _data:Object;
protected var _selected:Boolean;

The following test code adds an asterisk in front of the node labels of a Tree component.It works in a trivial Flash document but displays blank labels in a much more complex one. In both cases the library contains a Movie Clip with name, linkage identifier and AS 2.0 class all set to "MyTreeCell".
Scene:Layer:Frame:
createClassObject(mx.controls.Tree, "myTree", 1);
myTree.dataProvider = '<node label="Mail"><node label="In"/><node label="Out"/></node>';
myTree.cellRenderer = "MyTreeCell";
