Html Text Under A Wmode:transparent Swf Not Selectable?
Jan 9, 2008I searched and searched.Anyway, I have a swf sitting in a layer above html text. It's set to wmode transparent, and looks fine. it stays small until rolled over, then the buttons slid out as expected. However, when the swf buttons are still hiding, the html text in the area that the swf buttons will eventually occupy is not selectable when directly clicked.

View 1 RepliesFlex :: RadioButton In Custom DataGridColumn ItemRenderer In AS3
Apr 30, 2010I have a datagrid that I want to add a column of radio button using AS3 (instead of mxml). I was able to do this with a custom itemRenderer.
var dgc:DataGridColumn = new DataGridColumn();
dgc.itemRenderer = new ClassFactory(com.mypackage.RadioBtnColumnItemRenderer);
In my RadioBtnColumnItemRenderer.mxml, I have a box with a radioButton... like so:
<?xml version="1.0" encoding="utf-8"?>
<mx:Box xmlns:mx="[URL]" horizontalAlign="center" verticalAlign="middle">
<mx:RadioButton id="btnRadio" groupName="btnRadioSelect"/>
</mx:Box>
When I run the application, the radio button shows up in the column as it should. However, I cannot select just ONE of the radio buttons. I am able to select all of them, but I don't want this... I want the ability to select one and then if I select another one, then the first one is unselected and the current one becomes selected (just like you would expect radio buttons to work).

Actionscript 3 :: Eliminate Borders On A DataGridColumn In Flex?
Jul 26, 2011I can't see a way to get rid of certain borders within a DataGrid. I'd like to eliminate a side border on 2 of my columns so that they appear to look like a single column.I'm trying to implement a "clear value" button on each of my DataGrid rows. I was able to have a button show on a custom ItemRenderer from a separate ActionScript file, but I was unsure how to have the button click event propagate to the mxml file where the DataGrid is located. It would be much easier for me to have an extra unresizable column with a 'clear' button.
So, to reiterate: Is there any way to change the border style or eliminate certain borders of a DataGridColumn?
Flex :: Sorting DatagridColumn According To FileType Extensions?
Oct 28, 2011I have a DatagridColumn in flex with two names, TYPE and NAME. Now, when I am sorting a datagridcolumn, TYPE, it sorts the type using sortcomparefunction and gives the result which contains grouped and sorted order of elements. Ex. if I sort for type I get elements in pdf, doc, ppt in grouped order, but they are internally not sorted, ex: for the pdf part, I have elements such as:
TYPE NAME
pdf A1.pdf
pdf X2.pdf
pdf B1.pdf
Here the filetypes are sorted, but for a particular filetype, the elements are not, please notice that B1 occurs after X2, which should be sorted. Is there a way I can sort the second datagridcolumn after sorting the first one according to filetype extensions? I am using sortcomparefunction for sorting the elements according to type , which works fine. The signature is:
private function sortTheTypeColumn(itemA:Object, itemB:Object):int

View 3 RepliesFlex :: DataGridColumn Display Multiline String Data?
Aug 18, 2009Is it possible to display a multiline string in a Flex DataGridColumn?i.e. Display:
Text line one.
Text line two.
I've tried putting "
","
"," " when storing the string but nothing seems to work.Currently only "Text line one." is displayed and the rest is hidden in the cell. I would prefer not to use "wordWrap=true" to emulate this behaviour in the cell, but instead be able to manually put in newline breaks (although I could turn on wordWrap to avoid long text from hiding due to cell dimensions).
Flex :: Extending DataGridColumn For Custom Sorting Function
Aug 25, 2009I extended the DataGridColumn because I wanted to include a custom itemToLabel function (to be able to show nested data in the DataGrid. See this question.
Anyways, it also needs a custom sorting function. So I have written the sorting function like so:
private function mySortCompareFunction(obj1:Object, obj2:Object):int{
var currentData1:Object = obj1;
var currentData2:Object = obj2;
[Code].....
Whenever I try to sort the column, I get the error "Error: Find criteria must contain at least one sort field value."
When I debug and step through each step, I see that the first few times, the function is being called correctly, but towards the end, this error occurs.
Flex :: Accessing DataGridColumn Item Renderer Variable?

Flex :: Select / Set Style To DataGridColumn After Passing DataProvider
Feb 16, 2010I have a Datagrid thats being populated by different Arrays... (headers/columns change for the same DataGrid)... I would like to Select a Column of the Datagrid after it was generated by the Dataprovider and Bold it, and place it as the 'last column"
This is what I have.... and throwing an error:
private function populateGrid(evt:Object):void {
dg.dataProvider = evt as Array;
if (dg.columns.length > 0) {
for (var i:int = 0; i < dg.columns.length; i++) {
if (dg.columns[i].dataField == '_user_total') {
DataGridColumn((dg.columns[i].dataField)).setStyle('fontWeight', 'bold');
}}}}
This way I would like to have One Datagrid (for different Arrays) )without having the Columns fixed and declared (like in MXML), but dynamic, and would like a 'specific' column to be Bolded, and placed as the last column, in this example, the column with dataField _user_total.
Flex :: DataGridColumn With Array Of Objects As Data Provider
Mar 12, 2010I have a datagrid that uses an array of objects as the data provider. The objects are essentially key/value pairs:
{ foo:"something"}
{ bar:"hello"}
{ caca:"lorem"}
The datagrid has 2 columns. The first column is the key and the second column is the value. Right now my grid looks like:
My dataFormatter function makes sure that depending on the column (i.e. the dataField value) the correct key or value gets printed out. This works fine for displaying. However, as soon as I try and edit the value field it essentially adds a new value into the object with a key of '1'. For example, if I edit the {caca:"lorem"} object it will then contain the value {caca:"lorem",1:"new value"}.
Is there any possible way I can set the DataGridColumn so that when I edit a value it will update the value associated with the key rather than inserting a new value? I've tried using a custom item editor but it still does the insert. It seems like I need to be able to update the 'dataField' with the actual key value but I'm not sure how to do that.
