How can I validate the cells in a DataGridColumn individually? (ActionScript 3.5) The validation is configured per-cell, based on fields in the given row. For example
FIELD VALUE TYPE
age 13 Integer
height 13x3 Integer

I am attempting to combine two AS files that are acting as cellRenderers individually but not simultaneously for cells in a datagrid in a Flash document I have created. The first styles the cells to have alternating row colors and the second allows for non-text content to be rendered. The issue is whenever I attempt to combine them the document reports errors with "super" and "override" among others.

I have datagrid in which some cells (not entire columns) are editable and others are not(all is predefined).what we want to achieve is that to differentiate editable and uneditable cells applying differnet colors.
View 1 RepliesIs there any way to merge cells (vertically and/or horizontally) in a datagrid? At least, for example, is there a way to show that certain datagridcolumns belong to one group. For example, I'll take three columns: column1, column2, column3. All these three should be grouped to the Category cell with a rowspan of 3 -- a "super header" if you will.

View 2 RepliesI 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).

I 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?
I 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
I have the following datagrid:
<mx:DataGrid id="question" x="9" y="289" width="100%" height="54" visible="{false}" >

I need to access the data pointed by the dataField, and bind it to a label, but i don't known how to get it.
<s:Label id="debug" x="575" y="106" width="56" height="35" text="{data_from_coloumn_grid_ans1}" />

I am using the flex datagrid to allow the user to edit some data. My update process relies on a CollectionEvent of type update. Basically I catch this event package the values and update the database. However, if the user edits a cell then moves to edit a cell in the same row the value is updated but a collection event is not fired. Only when clicking out of the row the event is fired. Has anyone had experience with this. I have heard the datagrid is a little quirky is this one of those quirks or am I doing this all wrong?
View 1 RepliesIs 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).
I 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.
Within a DataGrid, I have a DataGridColumn that uses a custom component as the item renderer. Within the component, I have an ArrayCollection that stores a set of value objects. My problem is that I cannot access the ArrayCollection values from outside of the item renderer component. Does anyone know how it would be possible to do this? I have posted a code snippet below.
<mx:Script>

I 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.
