I have a Adobe AIR application which has a datagrid. My requirement is to allow the user to make the column headers and the number of columns of that grid, customizable. 1. How can I get the column headerText values from DB? 2. If the user can enter the column names, it has to be saved to the DB and then loaded.

I am creating headerText for a datagrid (dgTop250). How do I get the variable headerStr to evaluate correctly in the last line of the function? With the code below I get the entire string as the column header in the datagrid, not the evaluated expression that I need. Variable colName is evaluating correctly. I tried creating an Object of headerStr and using Object.valueOf() in the last line, but got the same result as before.
public function get250(event:ResultEvent):void {
(var i:int = 0; i <= dgTop250.columnCount; i++) {
var colName:String=dgTop250.columns[i].dataField;[code].......
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 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 currently learning flash (slowly), where everything is taking me a quite while to do! But I'm learning it for my job where eventually I will have to update some templates, and was hoping someone could advise how long this would take an experienced flash person to complete;The animation features a car flying in from left hand side, then three lines of text dropping down on the right hand side, one after another.How long would it take to amend this basic template - animation remains the same but car image is different and text is different.
View 1 RepliesI have a movieclip that contains a second movie clip. This inner movie clip is being animated so that it's transparency gradually fades in. If you go into this inner clip, in addition to all the objects that make it up, there's a layer of text. I want to be able to place multiple instances of the parent clip on the main timeline so that each of them are identical except for the text that exists in the child movie clip, ie. I want to be able to customise this inner text.Is this possible to do? I mean if I place a number of instance on the root timeline and change the text of each of these instances, will they remain unique
View 3 RepliesI have an AdvancedDataGrid where i build the columns dynamically (variable number of columns) in ActionScript, and i want the dataTip to display the column headerText when the user hovers over a cell. Adobe's example dataTipFunction:
private function tipFunc(value:Object):String
{
if (value is AdvancedDataGridColumn)
return "Column Name";
[code]....
But in this case the value is only an AdvancedDataGrid column if the user hovers over a column header? I want the dataTip to always show the headerText for that column. So if i have to use this function, then how do i get the column headerText for a cell? And as i understand the dataTipField i can't really use it to statically equal column.headerText (dataTipField = headerText).
I'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 am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

I 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.

For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values

I am attempting to style the headers in a flex datagrid and I keep getting the warning:
Type DataGrid in CSS selector 'DataGrid' must be qualified with a namespace
What does this mean? I have gone through a bunch of tutorials and none of them have worked. It seems like changing a the colors in a datagrid should be relatively simple.
Here is a code sample:
<mx:Style>
.headerCustomStyle

fontWeight: "bold";

in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.
View 2 RepliesI have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.

View 5 RepliesI have a datagrid which is editable and I need to send that back to the database via a CFC for insertion into the database after all the editing is complete. Dumping the array collection to cfdump tells me that I have an array with items and a structure but i cannot understand how to "loop" through each and insert into the DB.There seems to be very little written which actually works!

I have several datagrids with changing columns. For the text fields the datagrid's sort function neems to be making a case sensitive compare. eg. the following list sorted would look like this apples strawberries Autos Autos should be with apples but since the capital A is counted differently all capital letters come after. I've found a lot of information on setting a CASEINSENSITIVE flag, but I can't figure out where to do this. The best solution would be one where I can override the default behavior to be case insensitive for all my datagrids and all my compare functions.
View 3 RepliesI am in a situation where user gets the cars data from the database based on the selection and displays it in datagrid like below ( for example)

Honda Civic 2009 12
and there will be a link next to datagrid to get Pie chart based on the data displays in the data grid . The pie graph should display grouping by company and the count . I mean for the above example that should give with two pie items , one for GM showing the number of vehicles ( in this case 3 ) and Honda showing the number of vehicles ( in this case 1 ).
I thought of getting it from the database by querying and grouping it .But here the problem is after getting the data above in the datagrid user can able to filter at client end ( By year or model ) and can say get graph . This time that should only display the graph for the data visible in Datagrid .Grouping on database for every operation is becoming expensive. Since we have already data available at client end , is there any way to group it at client ..?
I am loading the data externally from xml and displaying in a datagrid. I have 2 buttons addRow and deleteRow. My datagrid headertext names are "name" "age" "rollno" "image", where image also will be loading externally thru an xml file. now when i am pressing the deleteRow button, whole row is getting deleted but an image icon is still appearing under "image" headertext. It was not an actual image but a blank image icon kind of thing is appearing, how to remove the icon. i want my whole row to be deleted. but its not happening.

What I'm trying to achieve is to print all the data inside my spark datagrid.

var printJob:PrintJob = new PrintJob();

<mx:DataGridColumn headerText="Visible" dataField="visibleInd" width="48"

But in this case my code does align the checkbox in the middle, but does not save data in my dataprovider.
