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 RepliesIn my Flex app I am using a repeater to show a report on my database data. On this report the user can "drill-down" on the data to show more detail. In order to make this easier on the eye I have a header label and then a datagrid within the repeater.Whilst this works perfectly, because the dataprovider for the datagrid comes from an array in the repeaters dataprovider, it is causing the following warning:Data binding will not be able to detect assignments to "report"The warning is for this line:
<mx:DataGrid id="dgReport" dataProvider="{rptReport.currentItem.report}" rowCount="{rptReport.currentItem.report.length}">

I have a form that consists of two data grids and a button. Datagrid 1, "myStaticDataGrid", has values I have added for the user to select from. I want the button's click event to send the current selection of myStaticDataGrid to the second datagrid, "myDataGrid". I have been able to accomplish this if I use a text box and a datagrid but I am having trouble finding the right syntax to grab the selection data from myStaticDataGrid.This is my attempt using the two datagrid approach:
<s:Form id="myForm">
//The values from this grid are determined once the button is clicked.
<s:FormItem id="myDataGrid">

I am reading dynamic data from the MySQL using JSP and it's forwarding the details in the form of XML to the Flex. I would like to bind this XML data to the datagrid. Am able to bind the data if the datagrid has only one column but don't know how to bind data which contains 2-3 columns.

View 1 RepliesI am trying to bind a datagrid item to a combox, so that when the user selects the item in the datagrid the form displays the selected data for editing, however one of my items is a combobox using a dataprovider.
I would like the item selected in the datagrid to match the selected item in the combobox, this part is fine however if my datagrid item is null then I cannot get the combox to set the selected index to -1?(the same happens if you use the CRUD wizard in Flex builder 3 for ColdFusion)I am using the following code for my custom combobox:

If user change the value of the TextInput, then click refresh button to retrieve the data model from backend again, the GUI value will not change back. Re-binding not happen, Since the value of data model not changed, no propertyChanged event fired.In this case, I must Programmatically set the model value to the GUI after data refreshing done.I know bi-directional binding can solve this problem(when user change value on GUI, set the new value to data model immediately). But sometimes I cannot use bi-directional binding, for example, the data model is a int, but user input a non-int value, I cannot set the value to data model. So the value in data model do not change, when refresh data, rebinding still not happen.
This will make the data binding useless. How to resolve this?I put pseudo-code here for now, I will put real code later:1. retrieve a data model from server, via blazeds or something else.2. bind the model to a TextInput on GUI.3. user change the TextInput text.4. User click a refresh button, triger retrieve the model value again.5. Now since the model value do not change, no PropertyChanged event fired.6. GUI value still is the user's input, not the value from the model. can clear the model value before set the velue back, make re-binding happen.(but sometimes you do not know how to clean the model value, take int for example, you may do not know the original value and happen set the same value). Or I can manually set the model value to GUI. But both are not good looking.
I've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".

Does there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components. Is it possible to use something like the Spark DataGrid with one item laid out vertically. It would only have to support:

Here is what is happening:
1. I have a datagrid (which I am generating dynamically)
2. If I select a row and edit it (on clicking it opens a pop up and when i save data in that, I just update the data provider of the grid locally).
3. As soon as data provider of datagrid is updated, the datagrid scrolls up in a way so that selected row comes at the top of datagrid.

View 2 RepliesI want to constrain the height of a flex component to the height of the browser viewport.
The component's children are populated from a database table using a repeater, and are basic checkboxes. There are enough of them that the flex app ends up being about twice the height of the screen, which means some of the rest of the layout goes crappy on me. How can I force the component that contains these to limit itself to the size of the viewport?

I have two datagrids 1. OPTION GRID and 2. ELECTION GRID. I have used VBox container as itemRenderer in ELECTION GRID which consists of TextInput in Description Column. The following is the sample SWF.
Whenever the checkbox is selected in the OPTION GRID i have to add a corresponding text input with description value in the 2nd grid (ELECTION GRID) for all the rows. Suppose if two checkboxes are selected, i have to add two textinput in the 2nd grid and so on... This is working fine. But whenever if i edit the textinput and scrolled up or down, the value gets collapsed between the rows or get vanished. I suspect that the itemRenderers will be re-used for the other rows while scrolling. How to retain the edited value in textinput ?
The following is the code.
Main code :
<mx:VBox width="100%" height="100%">
<mx:Label text="OPTION GRID :" fontSize="12" fontStyle="normal" fontThickness="15"/>
<components:CAEventDetailDataGrid width="100%" height="20%" dataProvider="
[Code].....
The Election Event is a customised event which will be triggered and invoke the listener function addTextInput whenever the checkbox is selected/de-selected in OPTION GRID.
private function addTextInput(electionEvent : ElectionEvent) : void
Is their a way to retain the edited value in TextInput ?
How can I make my datagrid have its first column fixed and scroll the reset horizontally and vertically?
View 1 RepliesI'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'm using the SpinnerList component in a flex mobile application, the spinner turn too fast for my need, is it any way to reduces its speed.

Can't seem to bind to data from within a custom component. I've tried BindUtilis and {} but can't seem to fathom it out. Here's what I've got:
I have a class DataModel which has been made bindable
Within Mainn.mxml I have two components: DataGrid (used for testing) & CustomComponent (which extends Canvas)
When the data within DataModel.somelist is updated the DataGrid reflects the changes but the CustomComponent doesn't appear to.
I was expecting to see the trace (CustomComponent.dataProvider) fired whenever this._dataModel.itemList is changed. [code]...
I have a custom component based on mx:ComboBox. Within it I connect to an HTTPService (the url is passed as a paramter) and bind the combobox.

When I tried to run this code Flex throws an error. It says that loadDetails is not defined. I suppose that error is because of scope.
