I have datagrid binded with data acquired from web service which, as you may suspectretrieves data from some db. Datagrid has some editable columns and I want to update db through appropriate web service call without adding button "Update" as a last column in datagrid.
View 1 RepliesOK I have an AdvancedDataGrid. The data I feed it is XML that looks like this:

<stat associate="John Doe" date="09-07-08" customer ="Amanda Jones"/>
<stat associate="John Doe" date="09-07-09" customer ="Henry Scott"/>
But I am grouping by associate so it ends up looking like a tree like this:

View 2 RepliesI have a custom <mx:DataGrid /> that is updated with data from a ColdFusion server every 60 seconds. I've noticed that every time the DataGrid updates and redraws the scroll position is reset to the top.
Is there a way I can preserve the scroll position for my DataGrid?

View 0 RepliesIn my Flex Project using Cairngorm, I have a model that stores a bindable ArrayCollection displayed by a DataGrid. My problem occurs when the model is updated by the responder (from a Java service, after an "update" event), because the focus located in a cell of the DataGrid is lost (the scroll position il also lost). So, I retrieve the position before the update, with DataGridEvent.ITEM_FOCUS_IN event :
myModel.focusedCell.rowIndex = e.rowIndex;
myModel.focusedCell.columnIndex = e.columnIndex;
But, from where restore these parameters ? How to trigger this update only when the model is updated ?
I have a Datagrid that is being populated by an ArrayCollection (rows) of Arrays (columns).I need to update the headerText of each column based on a List that will correspond with the total number of items within each array in the arraycollection. What is the best way of doing this? I know that I can set a listener in the List and update the headerText using (matrixDatagrid.columns[i] as DataGridColumn).headerText but I am looking for a cleaner solution.

I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)
[URL]
The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.
If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.
On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG
My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.
How can i update multiple cells of the same row changing the value of a single cell of the same row ??
Example: id, height, weight, fat percentage, corporal mass. When i change one of the values in a row (except id of course) the corporal mass cell value must change using a formula like: (height/weight2)*fat percentage*100. Is this posible with Datagrid or AdvancedDatagrid in Flex ??
I tried using custom item renders and inserting actionscript code inside the datagrid with no good result.
Im working with a flex application that pulls data from a java class file using message handler event. The received message string is added to ArrayCollection. The string consists of codeID and other values related to codeID. Had displayed the detail in a datagrid. The codeID is randomly generated and is pushed to flex for every second. Now, the problem is, I needa update the datagrid cell values, for instance, if i have pushed codeID's of (0001,0007,0005,0003) to the front end, that displays the corresponding values of each codeID in the datagrid, second instance of (0001) should update records in the existing row of (0001). I tried to check the existence of codeID in ArrayCollection using search algorithm, but dont know how to proceed further.
View 1 RepliesI have a component A in my flex project where people can vote for their favourite artist. Someone "likes" an artist, it get's updated in my database. There is also a component B that shows a chart of the most liked artists. I call the data from the database on creationcomplete in Flex. The problem is that when a person first votes on an artist, it will not be visible in the datagrid untill the user reloads the main page (?) or reopens the entire application. So i was wondering how i can update the datagrid everytime someone adds a vote to my database. I'm now using an update button, but that's not very user friendly of course.

I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.
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.
Is it possible to dynamically show row index for DataGrid rows ?
I have a static ArrayCollection which is set to be DataGrid's data provider and I would like to always have row numbering for each populated row (e.g. in a column called "#").
I want show a image onmouse over inside data grid to each row, so if I click on that image, some function should call(as per my requirement).
<mx:DataGrid width="320" height="624" verticalScrollPolicy="on" dataProvider="{blocked_Usernames}" editable="true">
<mx:columns>
<mx:DataGridColumn headerText="Blocked User Name" dataField="blockedUsernames" editorDataField="value"/>
<mx:DataGridColumn width="20" editable="false">
<mx:itemRenderer >
<mx:Component >
<mx:Image source="@Embed('assets/image/Close.png')" width="10" height="10" autoLoad="false"/>
</mx:Component></mx:itemRenderer>
</mx:DataGridColumn></mx:columns></mx:DataGrid>
I want to know how i show the tool tip of each data grid row or show some specific column's data in tool tip.
View 1 RepliesI 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 can successfully add a validator on an item in my datagrid, by passing in the particular element in the dataProvider to the validator, but I can't get the red border to show up around the cell if the validation fails. I have stepped through the validator, and confirmed that it is passing back a failure, but I can't figure out why the red error border doesn't show up. I have a feeling its because I am passing the item in my dataProvider as the validator source, rather than the 'cell' item, but I can't find a way to access the cell.
View 1 RepliesI have made a program in Flex for creating simple schedules, similar to MS Project or Vico Control. I have one problem that I would like to solve. (You can see it here: OnTime Project Scheduling tool made in Flex
The tasks of the schedule are represented as Gantt Chart, for which I created a itemRenderer inside one of the rows in the DataGrid. The tasks are shown as gantt diagrams, but I would also like to show the connectivity between tasks.
take a look at the image below, to see what I am trying to accomplish here: (above is the image of how datagrid looks now, and below is the thing I would like to add)
how I could do this inside DataGrid's item renderer?

View 1 RepliesI have a data grid where users can drag columns and reposition them. But there is a strange requirement that some columns should not be draged to the left of some other column. eg, assume the columns are: name, price , start date, end date, The end date should not be dragged and placed before the start date. i.e. The user can have start date, price , name , end date. name, start date, price , end date. But at no point can end date appear before start date. Is there a way to do this flex? Is there a way to know where the user is trying to drop the column and show error message ?
