Flex :: Programmatically Update Datagrid Columns HeaderText?
Feb 11, 2011
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'm new to Flash and PHP. I'm using the FlashBuilder with PHP product. I have a data grid that is connected to a PHP script that retrieves and updates data via the 'Enable Data Management' function. If I modify data on the grid by using the screen and call .commit(), everything works OK.
However I would like to programmatically change some of the values in the data that underly the grid and have those changes get back to the update function in the PHP script when commit(). is called. But I can't figure out how to change the underlying data.
Here's the code I've tried: (the object that I pass back and forth to the PHP script is call MailPiece. I want to set the WORKORDERNUMBER field on each row of the data)

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 want to save remotely (on a database) the state (visible columns, columns width and order) of a Flex3 DataGrid.For width and visibility I can simply save them by accessing each column attribute.. But for the order? Do I have to create the dataGrid dynamically?

I have a 1 row, many column flex datagrid. I would like to turn the dataGrid on its side, so that the column headers become a single column running down and v.v. Is there a way to do that in the DataGrid? Or am I stuck manipulating the data presented to the grid?
I have an object like:
x=y
b=u
o=p
u=e
w=p
And I'd like a control that is visually similar to that. Currently the datagrid displays the object as:
x b o u w
y u p e p
Which is too horizontal for my case.

1) Using datefield as item renderer in flex.I am dynamically creating datagrid and its columns. like
dataGridColumn=new DataGridColumn();
dataGridColumn.dataField="invoiceDTO.invoiceDate";// I read this value from XML
dataGridColumn.editorDataField="selectedDate";
dataGridColumn.itemRenderer=new ClassFactory(DateFieldRenderer);
dataGridColumn.rendererIsEditor=true;
But when UI is generated i get the error invoiceDTO.invoiceDate not found on the TestDTO
//Test DTO
public class TestDTO
{
public var invoiceDTO:InvoiceDTO;
}
My objective is my dataField should be binded with datafield inside the datagrid.How can i do it in actionscript
2) I need to present combobox as item renderer. (same like case 1). But how can i assign dataprovider in the combobox which is present inside the datagrid.

I am unable to find if the spark DataGrid supports moving / reordering the columns. If not what could be the best solution? Maybe using the mx version?
I want the user to be able to drag the columns and arrange them.

I created a component that is multiple datagrids side by side that share the same columns (each datagrid is the same as the one before but with different data).ProblemThe header text only shows up on the last datagrid. How can I get the text to show up on all the datagrid headers?Here is how I instantiate the component.

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 16 columns in a DataGrid in my Flex app. The first 15 look fine, with the column, simply containing the text, but the last one has a lot of extra space. Essentially, the columns are just big enough to fit the first 15 and all that extra space is tacked onto the 16th column.
How can I evenly distribute the space over each column?
<mx:DataGrid x="127" y="9" id="view"
dataProvider = "{currentBuffer}" width="497" height="480">
<mx:columns>

I have a data grid with an Combobox itemRenderer in it. What I have is a grid with a person id and person name (more stuff in grid but I am struggling with this). In the person name column I have an combobox with all the people on then system's names and id's. What I want to do is when I select a person in the combobox I want the combobox to populate the person name fields (which it does) but I also want to pull out the person id from the combobox and populate the person id column in the data grid as well.

I have a datagrid which displays details for a product. For a particular product i need to display its Id current status(Available/ Not) and which category it belongs to. The category part is a bit different from what it seems to be like. Product A can belong to Category A, B and C while product B belongs A ,c and D and so on. Structure of this table would be something like The category columns are retrieved from database and passed as parameter to construct the columns dynamically in Datagrid. I have defined the following Datastructure on UI to handle this.
Product{
var productId:String;
var productName:String;
var status:String;
var categoryList:ArrayCollection;
}
I am not sure if this will be able to solve my problem. I think I will need to have a Map containing category Names and if it is applicable for that product.

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.

I have a question I came up with 3 days ago about how to do the blue underlining of a datagrid row programmatically. I thought to have found the solution, with just adding the column and row Indexes to the datagrids editedItemPosition Property.It turned out, that this is just practical if you want to be able to edit the grids row right away. But what if I just want to underline it with the blue color?Additionally how to detect that a list based Item got this kind of selection? es there a event to detect that? whats the name of this kind of selection?

I 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 ?

I have a question about the Spark DataGrid and how it works in terms of garbage collection. What I'm finding is that if I dynamically add and remove columns from the DataGrid at runtime, the GridColumns and ItemRenderers never get freed from memory.
For instance, if I have a list with 10 items and I create 10 columns, there will be 100 ItemRenderers and 10 GridColumns. If I remove all of the columns, they are still there.

I am trying to figure out how to manage a Datagrid based on an XML object like this:

I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates.

Is there a way to get the columns to resize to the width of the new Datagrid instead of overflowing and showing the scrollbar? I've tried on the skin, setting all relevant properties and ran out of options. I just want it to behave like the previous Datagrid where the columns would resize to the width of the datagrid.
