I've gotten a checkbox header renderer to work well with flat DPs, but a hierarchical collection view is another story. On click, I want it to select all checkboxes in a given column. Here is my code:
[Code]....
im my flex application i have a datgridas follows
<mx:DataGrid id="grid" >
<mx:columns>
<mx:DataGridColumn headerText="Select" dataField="itemSelInd" editable="false"
[code]....
I have to create a custom header for the AdvancedDataGrid component. The custom header must have two buttons in it. The custom renderer must be applied to more than one column.
How I can fire, dispatch and handle events from the custom headers?
In my project i used one select all button for select all checkbox at click event . But i used datagrid ,iteam renderer within checkbox so no id of checkbox then how to select/unselect all checkbox ?
<mx:DataGrid id=newdatagrid>
<mx:columns>
<mx:DataGridColumn headerText="1" rendererIsEditor="true"
[Code]....
how can i implement select/unselect all button for checkbox?
Getting error while run the checkBox item renderer in advanced datagrid with out data.
Error: Cannot access a property or method of a null object reference.
Code:
public function set listData(value:BaseListData):void {
_listData=value;
_dataGrid=value.owner as AdvancedDataGrid;
_dataField=(value as AdvancedDataGridListData).dataField;
}
Here value is coming null, so I am getting above exception.
I'm trying to remove the tooltip from the checkbox inside an inline itemrenderer in a datagrid but I still get the tooltip box but with nothing in it. I want the tooltip box removed completely.[code]

I'm creating Datagrid dynamically and giving each row's first column a custom checkbox cellrenderer as noted here: [URL]. I have added an ITEM_CLICK event listener to the datagrid as such:
Code: datagrid.addEventListener(ListEvent.ITEM_CLICK, ToggleCheckBox); However, for the life of me I cannot figure out A) how to target the CheckBox specifically, B) how to toggle its' selected value, and C) how to finally update the datagrid view to reflect the toggled option.
Code:
private function ToggleCheckBox(e:ListEvent) {
// do some magic
}

View 2 RepliesThis 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 shows only country details but if I tried matches and isEnable not found in array. How can I found is isEnable and matches details?
ow do you display HTML formatted text in a Spark custom item renderer (Actionscript)?
Sample Code:
The html content in item.post_content displays as plain text in the IconItemRenderer messageFunction snippet below (which is just the default generated code for Icon Item renderer):
<s:itemRenderer>
<fx:Component>
<s:IconItemRenderer iconField="iconField"
iconWidth="64" iconHeight="64" labelField="post_title" messageFunction="getPost">

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.

I have a page (below) that has a datagrid that lists "item"'s returned from an XML file (below) and when it loads it created a page in the viewstack for each item it finds (working) it also renders a page (below) inside each panel but i am having issues passing the data. Each page renders and loads but with the FIRST result of the XML data instead of each page having its own data they all have the same as the first page.

View 1 RepliesI have prepared a simple test case for a PopUpButton opening a TileList with black and red entries and it mostly works, but has 2 annoyances. I've searched a lot, tried several variants (added [Bindable] members in my renderer; added color member to the bids array; created my public override set data() method; ...) and has been getting some answers too, but they are way too general.
1) Scrolling "tl2" right-left doesn't work well: the entries are displayed in a mix of red and black. I know the TileList reuses itemRenderer, but how do I fix the problem?
2) In debug-mode I get numerous warnings: warning: unable to bind to property 'label' on class 'Object' (class is not an IEventDispatcher)

How do I wordwrap in a spark list w/ an itemrenderer? This posting at[URL] works 100% but when I try to set a separate item renderer, I can't get the word wrapping...instead, I get an ugly horizontal scroll bar. HEre is my mxml:

I have an mx:tree with with TreeItemRenderer as below.
Parent1 (Delete | Rename)
Child1
Child2
Parent2 (Delete | Rename)
Child3
Child4
Delete and Rename are link buttons
Now when i click Rename a popUp should be shown like
OldName : Parent1(Text Input showning present Name)
Enter New Name: Parent1NewName(Text Input for entering New name)
OK | CANCEL Buttons
Afetr Entering the new name,click OK,popup should be closed and need to get the value in the treeItemRenderer.
I have the logic to rename the Parent1 in TreeItemRenderer and also I m able to get the Parent1 in the popup OldName TextInput.But after entering the new name i m not able to get that new name in the TreeItemRenderer.
I use a spark List with a custom item renderer and an ArrayCollection for dataProvider.
The ItemRenderer looks something like
<mx:TextInput id="txtValue1" text="{data.myFirstValue}"/>
<mx:TextInput id="txtValue2" text="{data.mySecondValue}"/>
However, even though I change the text in txtValue1 or txtValue2, those are not actually changed in the object inside the ArrayCollection.
myFirstValue and mySecondValue are decorated with the [Bindable] tag.
My understanding is that if the text property is set to be bound a certain property, the changes should be automatically applied.
So the HACK (or so I think) that I use is to listen to the focusOut event of each textbox, and access the parent data provider and set the the values manually.
Is it a bad idea to inject data into an itemrenderer. The reason I ask this is because the state of each item is dependent on different changing data sources. So the original data is used to just display a new item, but there could be two to three other data collections that would be needed to determine the item's behavior. Is there a better way to do this? Should I be creating a custom DataGroup with the other data sources as properties on this custom container and then reference the data sources from the itemrenderer to the parent?

View 1 RepliesI am trying to access html files protected by basic authentication. Below is the code to do that but I still get the authentication dialog. I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog.
Is there a way to add authorization header to the subsequent requests as well?
