I have a bunch of dynamic validators that I create in my application.I have an mxml which contains a s:DataGroup.The DataGroup contains an itemRenderer. In this itemRenderer, I have a combobox which I want to validate.I perform the validation like this ont the creationComplete of the itemRenderer:[code]Of course, when I do this, the itemrenderer is recycling, and the validator appears in places in which i do not want it to.
View 1 Repliesi have an editable DataGrid, something like:
<mx:Datagrid editable="true" dataProvider="{arrayListPreferences}" id="preferencesGrid">

I have DataGrid with Dynamic Columns. The columns will contain ItemRendrer. I'm not familiar with dynamically adding ItemRenderer.
My code is:
var column:DataGridColumn = new DataGridColumn();
column.headerText = item;
column.width=150;[code].........
But when I add this I got an Error 1067: Implicit coercion of a value of type Class to an unrelated type mx.core:IFactory.
In my AdvancedDataGrid, I am adding dynamic values to cells by dragging a cell value to other cells. While copying, I am setting the value to listData and setting the Red color to the value in ItemRenderer. Everything is working fine, but when I scroll down/up, the values remains in the cells where thay are supposed to be(as I am setting to listData) but the coloring behaves wierd(as I am trying to set the color in ItemRenderer).
I don't want to store the color of the value, but I should be able to see the dynamically created values in Red color. Is there a way, I can do this? Do I need to set the color to actual dataprovider object and then check in ItemRenderer?

Recently I have found that most programs claiming to write W3c complaint code DO NOT! I have been incorporating Flash and Javascript which seems to wreak havoc on the W3c validators. I found a site that rewrites the code for you and it passes validation.

View 1 Repliesi 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:

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
View 1 RepliesI have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
I want to create a list of progress bars and update the list accordingly.I have group data in an Array as
<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....
The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as
<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>
Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").
How can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.
Navigation within a View (Easy)
<s:View>
<s:HGroup >
<s:Button label="Questionnaire" click="navigator.pushView(view.QuestionnaireCategory1View)"/>
</s:HGroup>
Navigation within a Item Renderer (Impossible?)

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.
What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.
And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.
Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?
It is ment for dynamic questionnaires.

What is the Difference between ItemRenderer and ItemEditor?And When ItemRenderer is initializing and loading?
View 1 RepliesI've created a custom ItemRenderer extending UIComponent and implementing IListItemRenderer. This renderer contains a Text-Object to display the value.
For editing I'm using the standard ItemEditor (TextInput).
Now, when I want to edit a value, I click on a cell and the editor is created. But instead of displaying the value which was displayed in the renderer, "[object Object]" is displayed.
I am using a custom componenet based off of text as an itemRenderer for a dataGrid that is displaying an XMLList. I want to be able to re-use this itemRenderer for multiple columns, how do I access the dataGridColumn so I know which field to assign to the text value?

I have a custom item renderer which I use for my DataGrid. The DataGrid has specified selectionColor, rollOverColor and themeColor. The Problem is that the custom item renderer, does ignore those colors, and doesn't give any Feedback...
I tried to add the lines:

setStyle("rollOverColor", 0xE1F5DE);
setStyle("themeColor", 0x3569B0);
But with no effect...
I have a advanceddatagrid that has around 15 columns. Some are string, some are numbers. I have shown 4 columns below. The number columns have formatting done for zero precision and 2 digits precision. The itemRenderer is just to show Blue Color if the number is +ve and Red Color if the number is -ve. It looks something like below
<mx:columns>
<mx:AdvancedDataGridColumn dataField="Name" textAlign"left"/>
<mx:AdvancedDataGridColumn dataField="Time" textAlign="right"/>
<mx:AdvancedDataGridColumn dataField="Score" textAlign="right" formatter="{zeroPrecisionFormatter}" sortable="true" itemRenderer="ColorRenderer" />

I have a list with a itemrenderer. When I put a button in the itemrenderer I can not interact with it. If I rollover the button the list item rollover is triggered but not the button's rollover. I can't click on the button either. You can see below I have a click event set in the itemrenderer and it is not called on click when I run app. Must I override rollover and click methods of itemrender? Why is it such a pain to put a button in an itemrenderer?[code]...
View 1 RepliesI have a flex combobox as a datagrid itemEditor. However, after selecting an item in the combobox, its necessary to click out of the combo (i.e. into another cell or elsewhere in the app) for the value to be committed to the combo. Prior to this, the combo sits 'proud' of the datagrid and the value hasnt actually been committed.
Is there a way to force the value to be immediately committed after an item has been selected and for the combo to 'lose focus'?

I have a Flex list and a custom ItemRenderer. I'd like to be able to have some items in the list use a different ItemRenderer (say, depending on the class of the item). Is this possible?
E.g.: <s:List dataProvider="{_systems}" itemRenderer="myItemRenderer"/>
Most items in _systems use myItemRenderer. But if element 3 of _systems is "specialSystem" the renderer would be "specialItemRenderer".
I have created a custom ComboCheck which extends the spark DropDownList that is a DropDownList of checkboxes. Inside of my itemRenderer I have the code:

This will also not cause the dropdownlist to reset to scrollPosition 0
