Flex :: Imagerender Based On Datagrid Value
May 22, 2011
I have a datagrid with an location and a list of activities Birdwatching, Boating, Camping. The datagrid is populated based on either a simple yes or no if the activity is offered at that location. I want to replace the yes / no with a separate image for each activity. I created a imagerender and I'm able to get the image to change but only to the birdwatching image. My question is, how can I get it to loop through that datagrid and display image according to the value?

I have a DataGrid in Flex, with one column a checkbox and another a numeric value. When the checkbox is clicked, the numeric value should change, either to 0 if the checkbox is unselected, or to a pre-defined minimum value if the checkbox is selected. Here is the code I have:
<mx:DataGrid x="0" y="45" width="272" height="525" dataProvider="{dp}" variableRowHeight="true" editable="true" id="equipmentDG" verticalAlign="middle">
<mx:columns>
<mx:DataGridColumn headerText="" headerStyleName="gridheader" width="20" dataField="included" editorDataField="selected" rendererIsEditor="true">
[Code]...
The value updates in the data (I can see it when I close and open the dialog this is in), but it doesn't update instantly in the data grid. How can I make the value visibly change as soon as the checkbox is clicked?

I've search all over today trying to find how to do this, and not being familiar with actionscript is starting to catch up to me. What I would like to accomplish is: I have a list of messages in a Datagrid coming from a dataprovider in another class, which in turn gets them from our Oracle DB. I need to all the user to set a visible state on the message, and then filter that out of the datagrid with the click of a button. I have the check box for hide, and it sets that value into the database. I can't figure out how to get the filterFunction to work with an array collection when the filter parameter is within the row data.Here is the code
public function filterResults():void {
modelLocator.notification.messageList.filterFunction = filterRows;
modelLocator.notification.messageList.refresh();

when I select an item from my combobox, the selected value in shown in the textInput on the same row in the datagrid. Basically I need some some in the change handler of the combobox I suppose.
HTML Code:
<mx:DataGrid id="myDG" rowHeight="25" dataProvider="{my_arrayColl}" width="100%" height="205" chromeColor="#D0CCAF" headerHeight="0" showHeaders="false">
<mx:columns>

how use a button (or movieclip) to filter information out of a datagrid based on an external XML document. For example, say, the data were types of fruit along with their corresponding prices, but the user was only interested in the price of apples. To see only those records or rows with apples and the corresponding apple prices, the user would press the "Apples" button.
Creating the datagrid seems pretty straight forward, it's just the second part that's stumped me. Whatever the answer is would seem to go at the end where the "trace" is now. There seems to be many, many Web sites that sort of touch on this subject.I typed of the following from memory (I'm at work now), but I think this is pretty much what I have so far.
import fl.controls.dataGridClasses.DataGridColumn;import fl.data.DataProvider;
var food:XML;var urlLoader:URLLoader;var urlRequest:URLRequest = new URLRequest("food_list.xml");urlLoader = new URLLoader();urlLoader.load(urlRequest);[code].............

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);

I 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?

import mx.containers.HBox;
import mx.controls.CheckBox;

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.

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 am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
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:
<mx:Style>

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.

I'm trying to setup a DataGrid that contains a column of combo boxes. The values of the combo boxes are defined by data specific to that row. I cannot get this to work though, I'm asking for a solution to this, either fixing what I have below or a recommendation on a different way.One of the columns of my DataGrid has an object derived from a ComboBox for an ItemEditor. The itemEditor is set like this:
<mx:DataGridColumn editorDataField="selectedItem" dataField="type" editable="true" >
<mx:itemEditor>
<mx:Component>

Does anyone know an Actionscript equivalent of the javascript getElementsByClassName.
What I would like to do is add a custom 'stylename' to various components which I can then use to get a collection of these objects and therefore process their visibility property.
The idea is I want to hide various components based on what roles a logged in user has - I just want to make this flexible by adding an array of rolenames to a custom property or use the stylename property on a Canvas or Panel etc.

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

here is the code for the set data function (itemRenderer is extending HBox):
override public function set data(value:Object):void {
_data = value;

I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.

I have a datagrid which is editable and I need to send that back to the database via a CFC for insertion into the database after all the editing is complete. Dumping the array collection to cfdump tells me that I have an array with items and a structure but i cannot understand how to "loop" through each and insert into the DB.There seems to be very little written which actually works! My MXML and CFC are below but give me the error of "You have attempted to dereference a scalar variable of type class coldfusion.runtime.Array as a structure with members." -which is nice

{LocationName:'Service A', Contact: 'Bob Jones' },

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.

I am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)
Company Model Year No
GM Chevy 2010 10
GM Chevy 2009 5
GM Pontiac 2010 12
Honda Civic 2009 12
and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).
I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?

Flex 4.5+ is I guess everyone is working on nowadays so I asked this question since I haven't yet find working both spark datagrid and the mx printdatagrid components together.
What I'm trying to achieve is to print all the data inside my spark datagrid. So when I do my research, we use the PrintJob or the FlexPrintJob classes.It works fine but when I need to print multiple pages since the data on my spark datagrid is quite long, I can't somehow find a way how to do it.The print output is only upto where the height of my spark datagrid.So in my research, they somehow managed it to use the mx:PrintDataGrid component.But sad to say, they did it with an mx:DataGrid also.how to use the mx:PrintDataGrid along with s:DataGrid.
var printJob:PrintJob = new PrintJob();
if (printJob.start())
{[code]....
If converting a spark datagrid columns to the mx datagrid columns is not possible, is there a way that I can print all the data on the spark datagrid using multiple pages?
