Flex :: CheckBox - DataProvider Variable Never Reflects Change
Jan 25, 2010
I am encountering a bizarre Flex 3.4 issue. I have a class that acts a dataprovider to my entire application named "DataProvider.as":
package {
public class DataProvider {
[Bindable]
public static var email_enable:Boolean = true;
}}
In an mxml form, "Settings.mxml" I have a checkbox control which is bound to the email_enable variable of my dataprovider class:
<mx:CheckBox x="452" y="170" label="{Language.loadLanguageResource('lblEmail')}"
id="chkEmail"
selected="{DataProvider.email_enable}"
change="onChange()"/>
All is well as far as getting the value, if I set the variable in my dataprovider to either true or false, the checkbox reflects this change; however, if I click on the checkbox and change it's value, the dataprovider variable never reflects the change.
I'm trying to change Flex 3 ToggleButtonBar dataprovider on user or admin log in. I'm trying to use 2 viewstack, and I've got a component where the login form is in the component. What should I do to define the dataprovider based on user log in?
I have a component that contains a list that implements a custom renderer. I use this component as a tooltip, keeping one in memory and just altering the databindings as necessary.
Something like this where TTComponent is a class that extends Canvas:
Now, what happens is when data containing many items is set to tt.data, the list resizes itself larger and displays fine. However, after this, if data containing few items is set to tt.data, the component momentarily displays larger than it needs to be, then resizes itself smaller.
What I'd like to do is have the component resize itself before it displays, so I don't see the resize on screen.
Is there a way to apply a renderer to a grid in a way so that it doesn't modify the values in the data provider? I have a datagrid and on one of its columns I have a customer renderer which overrides the set data function and converts the number value in the dataprovider to a word. My problem is that when I sort the grid by that column it sorts by the new value, whereas I want it to sort by the old value that was originally in the dataprovider. Here is my renderer:
My Flex datagrid automatically scrolls to the top when I update the dataProvider (ArrayCollection). I do not want this to happen, but I still want all of the objects to update. I am developing a semi-real time dashboard for a customer's management system, that will update often. If it scrolls to the top every time it updates, it will be very difficult and frustrating to use.I've attempted to use the following techniques to prevent this, none have worked.
I've attempted to dispatch a mouse event to hold the vertical scrollbar in place, I've attempted to lock the vertical scrollbar position value in place (saving and reassigning)..
In flex 4.5, I have an application that has a BorderContainer that loads a spark list (mxml style - _myList and the borderContainer is stored in a library outside of the parent application) that loads an arrayCollection with an itemRenderer (I should note said itemRenderer is not an inline renderer - on selection of an item in the list, the itemRenderer expands, loads a particular control within the item renderer based on data passed from the selected item in the list) and allows the user to perform a search. This works all well and good on startup/load, until I try to change the dataProvider for the list (my app allows users to switch data sources which then creates a new dataProvider with new variables). I have tried:
I have a simple list and a background refresh protocol.When the list is scrolled down, the refresh scrolls it back to the top. I want to stop this.I have tried catching the COLLECTION_CHANGE event and validateNow(); // try to get the component to reset to the new datalist.ensureIndexIsVisible(previousIndex); // actually, I search for the previous data id in the IList, but that's not importantThis fails because the list resets itself after the change).I hate to use a Timer, ENTER_FRAME, or callLater(), but I cannot seem to figure out a way.The only other alternatives I can see is sub-classing the List so it can catch the dataProviderChanged event the DataGroup in the skin is throwing.
I have an array collection as the dataprovider to a datagrid. When I change a value in the arraycollection, a particular row gets updated in the datagrid. I want to get the index of that particular row. How do I get it?
I have a Flex repeater that has a complex item template. When a checkbox is clicked, I need to toggle the visibility of a sibling button contained in the same repeater template. Since I can't add binding expressions to event handlers, I can't pass in the repeater item's index.
How can I access sibling components inside a repeater item?
I need a datagrid, which contains checkbox (4 no's) without multiple selection. And I also need a text area which should contain the selected checkbox's label/data. I tried using arraycollection but I am not getting.
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.
This PHP contact form works well and is very simple. I have one checkbox in the fla file. However, it keeps displaying 'No' in the email message field, whether the checkbox is selected or not. It should display 'Yes' if the checkbox is selected, and 'No' if the checkbox is unselected.Here is the PHP:
Im currently working on a project utilizing MX 2004 Pro and FSP. I use the method "getfilelist_del" to return a variable result that is delimited with ";".Im having the hardest time trying to figure out how to loop thru the result data to extract each value and return it to a dataprovider and/or convert it to an XML doc.[code]

I've created a flash form using components from flash 8 and can capture the values(variable name) from following components: listbox, radio buttons, textbox and textarea, dropdown list but.... I am unable to capture the value of my checkboxes.
i try this var myTf:TextFormat = new TextFormat(); myCb.setSize(150, 22); myTf.size = 16; myTf.color = 0xFF0000; myCb.setStyle("textFormat", myTf);it change checkbox font size and object size, but tick box remain the same, what should i do?
I have got a component within my flash form. I have a button that sends information to PHP (this is working). What I need is checking whether the check box is selected or not, so that if it is my button will go to one place, and if not then it will go to another (which I know will be done with an 'if' statement).
I am trying to assign a few variables to checkboxes that I am adding dynamically to the stage. There are like 40 checkboxes added dynamically and I need to keep track of a few variables for each checkbox.It will only let me assign a "name" to the checkbox. If I try something else like "Group" (see code), then I get a runtime error:[code]
I am using an component, and currently have a dataProvider working that is anArrayCollection (have a separate question about how to make this an XML file... but I digress).Variable declaration looks like this:
[Bindable] private var _dpImageList : ArrayCollection = new ArrayCollection([ {"location" : "path/to/image1.jpg"},
I am using datagrid and added 3 columns to it in flex project. Data is provided to each column by using itemrenderer. Itemrenderer is checkbox for each column. Name of columns are col1,col2,col3. I want to make the checkbox in col1 selected when i selects the checkbox in col2. But i am not able to do this.
The flex DataGrid colums are arranged alphabetically by default. I need to order the DataGrid colums as per the order in its dataProvider. The dataprovider is the result of the HTTPService . And the number of columns is not known to us . The number of columns depends on the HTTPService result.
I have a datagrid with dataProvider property set in MXML as: dataProvider="{pagedResult.lastResult}" How do I set the dataprovider in actionscript? I have: protected function getResult (event:FlexEvent):void { pagedResult.token = mydata.paged(); adg1.dataProvider = pagedResult.lastResult; }
