I have a main datagrid, and want to launch a window with another datagrid in it, bringing in a different dataprovider. However, when I do this it acts funnny, brings in some default datagrid information and then gives me an error when I try to set the dataprovider:"multiple initializers for property dataprovider. (note: 'dataprovider' is the default property of mx.controls.datagrid)"
View 1 RepliesI've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);
View 1 RepliesI have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.

My Flex datagrid automatically scrolls to the top when I update the dataProvider (ArrayCollection). I do not want this to happen, but I still want all of the objects to update. I am developing a semi-real time dashboard for a customer's management system, that will update often. If it scrolls to the top every time it updates, it will be very difficult and frustrating to use.I've attempted to use the following techniques to prevent this, none have worked.
dataProvider = updatedDataProvider;
dataProvider.updateItem(dataProvider);
dataProvider.source = updatedDataProvider.source;
dataProvider.updateItem(dataProvider);
I've attempted to dispatch a mouse event to hold the vertical scrollbar in place, I've attempted to lock the vertical scrollbar position value in place (saving and reassigning)..
I need to display DropDownLists in a column of a DataGrid in my Flex application. Here is what I am doing:
First, I have a item renderer function that creates a custom item renderer, and passes it a property that is an IList that will be used as the dataProvider of the dropDownList:
private function rendererFunction(item:Object):ClassFactory {
var itemRenderer:ClassFactory = new ClassFactory(AudActionDropDownIR);
itemRenderer.properties = {AudActionData: AudActionData};
[Code]....
First, how can I call the init function when the renderer is created? Second, when I set the column's itemRendererFunction="rendererFunction", the app will not launch, a white screen comes up. But when I set itemRenderer="components.AudActionDropDownIR", the app will launch, but of course there is no data in the dropdown list.
The flex DataGrid colums are arranged alphabetically by default. I need to order the DataGrid colums as per the order in its dataProvider. The dataprovider is the result of the HTTPService . And the number of columns is not known to us . The number of columns depends on the HTTPService result.
View 1 RepliesI have a flex datagrid. it is bound to an array collection. if the user sorts on column X it works fine. then, if the user causes the array collection to change, the datagrid forgets that it was sorted on column X.what do I need to do to preserve this sort preference so that the new array data will appear sorted by column X?
View 4 RepliesI am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.

View 1 RepliesWe are using as3Crypto library in my project. We have downloaded the code, modified a bit and started using it. Initially we have included the complete code as the part of the project. Now we are trying to compile it as Separate Library file(.swc). When we compile the code, we didn't get any errors, but we got one warning saying

When we check the code, we traced it to a code file AESKey.as, especially from a Static initializers code block. I can't simply ignore the warning as it is the critical part of my applications security.
I have a flex application in which I have a TabNavigator with multiple tabs and a datagrid in each of those tabs. I have bound s single array of data to each grid.
What I want to do is to bind each grid with a particular set of data in that array i.e. to distribute array contents among grids based on data type. For example items starting with letter A could be displayed in first grid, B in second, starting with C in third and so on. Hence you can say alphabetically distribute the data on different grids. The problem is that the data will be added randomly by the user.
To make one data array for each grid is not an option (due to design restrictions).
I have this error. I am very very new to the Flex world. I have this function which returns an ArrayList.
public function createDataProvider():ArrayList {
....
return new ArrayList(imgArray);
}
Later, I use it here:
<s:List id="pubmapList" dragEnabled="false" dropEnabled="false" dragMoveEnabled="false" dataProvider="{createDataProvider}">
Here, I got an error saying: implicit coercion of a value of type to an unrelated type mx.collections.ilist. I thought the IList implementation includes ArrayList.
what I need to do is combine 5 arrays with 5 individual strings (which have come from a JSON webservice) into one single list item in FlashBuilder Burrito. [code]I've pulled these out successfully and each one traces in the debugger, although as I need them all in the same list I'm struggling to establish them as a dataprovider together.If I push the strings and arrays together it is impossible to read properly, as the main Titles are at a different level to any descriptors for the products which are in the arrays.
View 1 Repliesrecently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)
View 1 RepliesI have a Datagrid with an ArrayCollection as DataProvider, the arrayCollection is partially generated by a remoteObject call, the dataprovider seems to works at least until I try to edit the field...By the RemoteObject I only receive an ArrayCollection with the field ip, but the datagrid looks for the fields ip, check and save...If I add/edit this new field it works, but only under particular condition
The DataGrid:
<s:DataGrid id="datagrid" left="10" right="10" top="136"
dataProvider="{listaIPCheck}" bottom="10" requestedRowCount="4">
<s:columns>[code].....
This code always work in the 3 points, so at the end of the call the ArrayCollection is always filled with the new values, but the datagrid refresh the items only in point #1 and #2.
What should I be using to pull information from either DataGrid or DataProvider Cells. I guess itemToLabel(), or getEditingData() doesnt work any more.

In a DataGrid, how can I force data() of all itemRenderers on visible rows to be called when I've made an update to the dataProvider.I'n the following the Grid isn't updated after pressing doSomething. If I have a large list the update is done when scrolling down and then back up again, or in the case of the TreeGrid i open/close a node.

View 1 RepliesI actually wanted to create an itemrenderer which will contain below code :
<mx:HBox xmlns:mx="[URL]" width="0" height="0" >
<mx:Label text="{data.xval}" />
<mx:Spacer width="100%" />
<mx:Image source="edit.gif" width="16" toolTip="Edit" />
</mx:HBox>
Now when I click on the image datgrid column should be editable, for that I am using a textinput as an itemeditor. Now I also want to highlight all those cell for this datagrid column which are having data more than 8 characters. I am able to do this separately using 2 different itemrenderers. But I want to get this all together. Can we have multiple itemrenderer for any datagrid column?
I'm trying to create a Flex DataGrid where the firstname and lastname are shown under each other, but in the DataGridColumn
Ideally I would want to do something like
<mx:columns>
<mx:DataGridColumn headerText="Column 2" dataField="time"/>
<mx:DataGridColumn headerText="Column 2" dataField="firstname,lastname" itemRenderer="renderers.FirstNameLastName"/>
so that both values get passed to the itemrenderer, is this possible?
I have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.
