I'm following flex tutorials but i'm not doing exactly as they do, so :hat i want I have an input text, with a button 'search'.I want when this button is clicked that the data returned by the function search are displayed in the datagridWhat i have :
The text input :
<s:TextInput includeIn="DetailServeurs" x="58" y="361" width="209" id="txt_search" text="Default text" focusIn="txt_search_focusInHandler(event)"/>

I have a datagrid with different types of columns, like I have checkboxes, combo boxes and text Inputs as the column types. Now I want one of the column type to a link, with the label "view". All the rows in that column are link with the same label "View" and on clicking it, I want a Pop up window to be opened?
This is my code:
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100%" height="100%">
<mx:Script>
<![CDATA[
[code]....
I didn't know how to bring a link in the datagrid. So used the Text control to display the "View" label. Now If I click this item, "View" in the datagrid, I want the Pop up function, i.e.,defectCommentsPopUp() to be called.
I've got a Gridcolumn in a Datagrid (Spark). The Column's dataprovider is a Number value that gets updated via Binding.Now, without an item renderer the cell displays the correct values.If I set an item renderer, I can't access the values in this renderer.My renderer looks like this, so nothing really do here (for now) but to trace the value, but the value is always NaN.
<?xml version="1.0" encoding="utf-8"?>
<s:GridItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark" width="100%" height="100%" >[code].......
without the renderer, the column displays the correct values, so apparently the DefaultGridItemRenderer works fine.As requested, here is my Datagrid;
<s:DataGrid id="dataGrid" dataProvider="{_listItems}">
<s:columns>
<s:ArrayList>[code]..........
_listItems is an ArrayList with instances of a model class, which has (amongst others) a property called change of type Number.
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).
I have been goggling a lot to find anything with link-based data visualization in Flex 4. something like below screen shoot (made using Ravis). Where user can drag these nodes, without removing the links and on double click of any node we can set some properties for that particular node. I found this Ravis (Birdeye), but not much of examples and support is available for that.
View 1 RepliesHow can you display a multi-line column header using the Flex Spark Data Grid for Flex 4.5?
View 5 RepliesThe data provider (ArrayCollection) for my data grid consists of objects with ByteArray (int) fields. How do I make the data field display as int without transforming my data provider?
View 1 RepliesI have a custom dataGrid that acts more like a 2D list (if that makes sense at all). I am dynamically creating the columns and recreating the dataProvider to suit my needs. While debugging I can see that I am creating the columns and setting them to the dataGrid and creating and setting the dataProvider, but for some reason I am able to see the dataGrid and the columns but not the data.
[Bindable]
private var mockData:ArrayCollection = new ArrayCollection([
{value: "425341*"},
{value: "425341*"},
[Code]....
how can I refresh the displayed data in a Datagrid when the underlying ArrayCollection changes?
<nmoschitz:dataProvider>
<mx:HierarchicalData source="{arrCol_groupedData}"
childrenField="accounts"/>
</nmoschitz:dataProvider>
Calling a simple refresh (like with a simple arraycollection as a dataprovider, or with a refresh on the Grouping Collection) does not work. Also re-assigning the arrayCollection to the Hierarchical Data and then assigning this one again to the Datagrid does not work (even with calling invalidateProperties() or validateNow()).
I have an editable DataGrid in Flex, with data full of numbers. The columns have no special itemRenderer, but a labelFunction, which returns the number as-is if positive, but puts it in parentheses if it is negative, like so
27.3 => "27.3"
-27.3 => "(27.3)"
Now, these cells are editable. When I try to edit a cell with a positive number, nothing is wrong. But if I try to edit a negative number, it starts editing (27.3) instead of editing -27.3. Because of this, when the edit is done, the labelFunction is evaluated with the new value in parentheses(i.e.,labelFunction is called with "(30.5)"), and converting it to a Number results in NaN. So, I want to know if I can make the DataGrid edit the data in the dataProvider instead of the label that it shows.
I have a DataGrid and I set the DataProvider to my data. When my data changes the DataGrid loses the selected row and the scroll bar jumps back to the top. How do I maintain the selection and scroll position?

I'm trying to get the title from the selecteditem from this datagrid (which is filled by a rss-feed) in a label. I've searched for ways, but I can't find how I should get this done.

dgAutoFill.addEventListener(ListEvent.ITEM_CLICK, showDetails);
public function showDetails(event:ListEvent):void {
lblTitle.text = ?;

i've working in flex for some years and it seems to me it's an awesome tool. Some days ago i've had an extrange behavior in my datagrid.
I have a php service which reads a database and sends this data to felx. The service and the info saved in the dataprovider in flex are working without problems, but when datagrid shows the loaded info, it shows many cells with wrong data. The data shown seem to be mixed with other cells. I have two registers: "The lightbulb is red" and "The dog is dangerous". But the datagrid shows e.g. "The lightbulb is Dangerous" or "The dog is red". When i see the dataprovider in a breakpoint all data is correct.
But it's even much strange when I click over a problematic cell, this automaticaly changes its content to correct values.

i have a datagrid which grows in size depending on the result of a call to my db. The call to the database returns an object with 30+ values for each row. When the number of rows returned exceeds about 80-90 the datagrid renders odd. It displays the first 50-60 rows fine but then it displays blank rows and they even continue to display outside the border of the datagrid.what is happening? Im using mxml webservice to retrieve the data.
<mx:DataGrid dataProvider="{resultsData}" rowCount="{resultsData.length}" allowDragSelection="false"
id = "confRoomLookupResults" width="948"

I am trying to refresh the datagrid to reflect the updated data after the user updates the database. I have the following code:

I have two Datagrid in flex. I am binding data from Datagrid1 to Datagrid2 like
(Datagrid2.dataProvider=Datagrid1.dataProvider as ArrayCollection;)

I have a DataGrid component that I would like to update every 5 seconds. As rows are being added to this DataGrid I noticed that every update causes it to reset the scroll bar position to the top. How can I manage to keep the scroll bar at its previous position?
View 4 RepliesPreviously I post a discussion on this matter on Flex Adobe forum and still don't understand what needs to be done. So, I'll try my luck again on stackoverflow.

I have some DataGrid with editable rows, which has also an option to add new row 'dynamically'. I mean, last row has some default data (e.g. "CLICK HERE TO ADD NEW ROW") and when user clicks on it, he can edit that value and new row will be eventually inserted.
However, I also have a column in same DataGrid which doesn't come from DataGrid's DataProvider. That column is used to delete specific row and it should only display clickable image with associated mouse click action (within custom itemRenderer).

I'm currently building an application that is presenting tabular (fetched from a webservice) data and have squirted it into a datagrid - seemed the most obvious way to present it on screen. I've now come across a few limitations in the datagrid and wonder how I might move forward. The data is logically split into groups and I would like to be able to have subheadings in the grid whenever I move to a new group. I would like to be able to highlight individual cells based on their content relative to other values in the row - ie highlight the cell with the highest value in the row. Is this possible with the standard datagrid?

View 1 RepliesThe 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 am trying to implement the following :
1> First column of datagrid has a checkbox.
