I want to add a ComboBox to a DataGrid. So far, the only way I've found to do it is like this:
<mx:DataGridColumn headerText="Header" dataField="src" >
<mx:itemRenderer>
<mx:Component>[code]..........
The problem is the initial value of the ComboBox isn't set correctly. If I hard code the choices, then the initial value is set correctly. I can't hard code the choices.
A combo box as an item renderer for a data cell in a Flex Datagrid has been demostrated at various blogs. What if that combo box has to have an external dataprovider that has to be set at the time of converting the renderer class to a ClassFactory.
View 1 RepliesCan some one please direct me to a example where a combo box has been inserted in a datagrid using as3 in CS4. I have a idea that it can be done using the cellrenderer, but i am not able to figure out how to achieve it. i tried searching on net but could not find any working example.I am working on a project where there are mutiple rows in the datagrid, and the values of the datagrid item can be changed using the combo box inside it.I have just started on actionscript so not much experience on that part. I have been searching on net for quite few thing and working them out.
View 1 Replies It might be something simple I'm doing wrong.I have an array populated by XML in a function by doing the following inside the function:
first_special.addItem({label: xmlMenuFile.item.headers[i],data:
xmlMenuFile.item.descriptions[i],data2: xmlMenuFile.item.hints[i]});
The problem I'm having is trying to figure out a way so that the "data2" will fill the text field "hint_txt" on ROLL_OVER of that items name in the list.I've tried to placing an event listener into the function that populates the combo box .this populates the combo box label and data with the Loaded XML File. This works
function changeHandler(ev:Event):void
{
menuText_mc.heading1_txt.text = ev.currentTarget.selectedItem.label;[code]......
I have two combo boxes. The first combo box's data is added through an XMLConnector object, the second combo box, I would like to populate through an on (change) event in the first combo box. The items in the second combo box would relate to the selection made in the first combo box.
I have attempted the following within the Actions for the first combo box:
on(change) {
switch(this.value) {
case "value1":
comboBox2.addItem({Label:"Label",Data:"Data"});
break;
} // end switch
} // end event
which is not working.
should an event be dispatched by comboBox1 and a listener be attached to comboBox2? I can't find any examples of this on the internet.. but i might be using the wrong search terms.
I've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);
View 1 RepliesI am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

How to turn Flex MXML DataGrid into something like Horisontal DataGrid? (may be some how with Flash builder 4?)
Keeping all stuff DataGrid has like eating data from data provider sortind dragging - droping items etc
I have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.
[Code]..
For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

i use combo box to display a list of items. The box'x length is smaller whereas the items length is large. So if i mouse over it i need to display the whole item as a data tip

Combo Box:

I did the following code. I know it's horribly written, but it's only a box with two combo boxes and a textinput bellow being added to a VBox, whose id is "garage". The problem, is that, however I do it, when I open the combo box the program slows down so much it's unbearable to use it any longer. I'd like to know if you have any idea on what's behind the ComboBox and the possible causes for this "slowing down" when I open the ComboBox..

How can I give value to combo box entries. For example, in combo box, I have Array Collection and inside it, I am adding strings like mx:String. I want to give it different value than the text.
View 2 RepliesCombo boxes in Flex are really awkward to use if you have objects in them addressed by properties, in my experience. In Flex 3.5 we had a working extension to the combo box that would populate a selectedValue property (and allow changing the selectedIndex by same).
Here's a quick example of what using one of these looks like:
<c:ValueComboBox valueField="country_code">
<mx:Script>
<![CDATA[
public function get selectedCountry(): String {
[code]...
However, this has stopped working in Flex 4. What's happening is that our existing component drove its changes by overriding the set selectedIndex() function, which is no longer called when the combo box's selected index changes (wtf?).Is there a working value-aware combobox implementation for Flex 4?

Background: I am doing some UI work where I allow the user to programatically add and resize controls on a canvas. Problem: When resizing a combo box through AS the dropdown stays at the same width as the first time it drops down. So user places combo box on the page, clicks the down arrow, sees the options, selects an option or clicks down arrow again to close, resizes the width of the drop down, clicks the down arrow. Now drop down is the same width as original. Have tried simple things like setting the width of the dropdown specifically and invalidating display list but it still doesn't work.

I'm now trying to do the same thing in a ComboBox. I know it's possible with either a classFactory or extending the ComboBox but I really can't work out how - there is so little information on things like the classFactory around.
I have a combo box in my application. I also have a variable called "Status". I want the combo box to be enabled only when the value of the Status variable is 5 or 6. Otherwise, I should not be able to change the value in the combo box. It should have the previous value only.. I had written a click event to disable the combo box. But even though the combo box is disabled, I get the drop down list of the combo box, and If I select some othe value in the drop down,it changes..Only after that it gets disabled.

The below code show the labels from previously selected list?
Steps to reproduce:
Click on List AB Open the list but don't select / click any item Now click on List CD Open the list again and you see A, B as labels instead of C,D but if you click on any item then everything comes properly

I'm starting a Flex app on a pretty big reporting engine and want to know how best to connect to a Postgres Database. I'd like to create a REST API architecture so I can use the service for more than just the Flex app(mobile possibly).These are my options I've found:
Datatype: either XML, JSON or AMF
Flex Service: HTTPService or WebService
Server(using PHP): ZendAMF, custom json_encode implementation, Zend_Rest_Server
I've got my views all mapped out, and the api functions designed. Basically what I need is advice on which Flex / back-end service combo to provide.
I am attempting to style the headers in a flex datagrid and I keep getting the warning:

What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:

Environment: Flex/As3/Cairgorm/composite component.I have two comboboxes and two datagrids such that the selection of combobox 1, inserts data into combobox two and the fist datagrid.The selection of combobox 2 inserts data into datagrid 2.I have setup the change event so that the user selection on each of the combo boxes do the right thing. The problem is that on the initial load of the comboboxes, the change event does not fire and subsequent synchronization data loading does not happen.Is there an event for getting the itemselected (1st item) after the combobox is initialized?

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.
