Is 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 have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.
I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).
public class EncounterDGItemRenderer extends Label
I found that my tooltips (datatips) stopped working once I started using this custom renderer. I also found that I can set the tooltip on the label in the
override protected function updateDisplayList
by setting:
toolTip=data['addedDate'];
This works find, however the problem is I need to choose a different data field based on the column. I was hoping for something similar to how a DataGridColumn labelFunction works - where I have access to "column.headerText" or "column.dataField". However I only have access to the underlying data object, not the name of what is being displayed (unless I am missing something).
Is there a way in a data grid item renderer to know what the column header text is, or do you have a different approach?
I 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.
This is the edit to my question. There is quite a bit of code here, but the problem area is below the second set of three line comments. I stuck the rest in just in case I'm completely wrong about where the problem is. With the "if" statement I can display fine in a run, but not in debug. If I get rid of the conditional it runs fine in debug, but not in a regular run. These errors only occur on the first run of the quiz. In either mode it runs fine fi I take a second quiz.

Ok, here's my requirement in short-I have a datagrid that is updated every time data update is received. Now, all I want to do is check if the present value in every cell in a specific datagridcolumn is less than the new value then color that particular cell green, if the present value is greater than the new value then color it red, else leave previous color as it is. Simple?Now, the coloring part is important but comes later. As of now, I need to know how to get present cell data in the labelfunction of the datagridcolumn.
// column is a datagridcolumn column.labelFunction = function(oData:Object) {
I want to separate the data from the PHP call to Different CollectionArrays So that I can use the data for a bar-graph;
I created a static version of the bar-graph and separated the Collection array manually I don't want this done manually I need to do it dynamically. So what I am trying to understand is where to put the event-listener how to add to a collectionArray then once the collection array(s) are built. use that information to build the bar graphs...
i have a text area, set to multiline. For some reason, when my text imported from xml shows up in the box, it starts several lines down into the box. So for example, my Text box is positioned with the top at the midpoint of my stage, but the text starts about 3/4 down the page, about half way down the text box. Can someone please tell me why this is happening and what I can do to fix it?
I noticed that when I put my cursor in the box and move it up and down, the rest of the text 'scrolls' into the frame, but otherwise it's cut off.
I'm building an application using flex 4. Using <mx:DataGrid> to display a table. I would like to add a <s:GlowFilter> to a DataGridColumn. How can I do so?
Is it possible to put an itemrenderer on the DataGrid itself rather than a datagridcolumn? I could only find examples for datagridcolumn. I want a generic itemrenderer on all the items in a datagrid...
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?
super.data gives me the whole XML item, super.parentDocument gives me the whole DataGrid
I have a DataGrid with 3 DataGridColumns. All 3 of them have separate dataFields.I need to get the datafields into an ArrayCollection and pass it to a funciton. I dont want to hard code the ArrayCollection.
I 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).
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 have an itemrenderer used by multiple datagridcolumns and I need to have some condition in the itemrenderer based on the headertext of the datagrid column. Can I access the headertext property from within the itemrenderer?
My itemrenderer extends the LinkButton control and implements the IDropInListItemRenderer interface.
I'm trying to reach the dataField of a DataGridColumn in the itemRenderer. Below is the dataGrid:
<mx:Script> <![CDATA[ [Bindable] public var weeksOfMoth:ArrayCollection = new ArrayCollection([
[code].....
In the set data function of the itemRenderer, I receive an entire week (which is ok), but the itemRenderer doesn't know which day to use because the dataField is unknown. Does anyone know how to reach this dataField in the itemRenderer?
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
Basically I'm trying to output the contents of an XML document into a dynamic text field (as loaded - not just its node values and content - the entire thing - into a variable called _root.log). The text field is set to show the variable value of _root.log.This is the actionscript...
PHP Code: var newProfileXML:XML= new XML("<contacts result='true'><contact name='John Doe'/><contact name='Jane Doe'/></contacts>");
In my application, I am using a BarChart to display data. However, the text in the category axis can be too long to display on the chart, so flex adjusts the font size automatically to the point that the data is either unreadable, or the text is partially visible.The length of the text varies every time new data comes in, so I can't set the gutterLeft attribute to a static value at runtime.Two things that come to my mind are:Change the gutter dynamically according to new data/Have a scroll bar on the categoryaxis so that if any text won't fit in the space, the user can scroll to see it.[code]
The question seems to be simple, however it create problems for me. I have a dataGrid with two dataFields: peerID, name. The information in a grid updated dynamically when new user joined the group (I'm creating a chat). I need that information about user deleted from a grid after it's disconnect. So, on "NetGroup.Neighbor.Disconnect": event i want to compare "event.info.peerID" value with all peerID values in a grid and delete info about disconnected user.
I'm trying to use next construction:
for (var i:uint, len:uint = txtDataArray.length; i < len; i++) { if (txtDataArray.source[i] == event.info.peerID) {
[code]....
But it doesn't work at all!
I'v noticed that construction txtDataArray.source[i] (or txtDataArray.getItemAt(i) ) returned [object GridColumn] insead of value. So, I have two questions:
1) How to get the value of exact cell?
2) How to organized info delete after user disconnect?
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> <![CDATA[ // Cannot access arrFiles from here.
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.
