I'm working on simulating a diagnostic tool and I'm using a dataGrid as part of the sim. I'm populating the dataGrid with an xml file. It loads and runs fine.I need to change the values of the dataGrid cells when the user presses the buttons. For example, if a cell row 0, column 0 has a value of 51, it needs to change to 45-88 when the user presses a button.
View 1 RepliesIn Flex 4 using a pre populated data grid, how can I get or set specific values programatically, IE I wont be using selectedItems etc.
How do I reference the value of a cell in row 4 colum 6 for example.
I have Flex 4 DataGrid, what I would like to do is when an cell has been edited, I would then like to walk through the values of that column and preform math on the values, e.g., I want to total up certain values.
1) How do I reference individual values of a specific column so that I may set them.
2) How do I then set those values or should I create a new column array and pop it in place of that column.
I have an XML file with this data.
<resultSet>
<MerchandiseAssortmentCategory>
<merchandiseAssortmentCategoryId>275</merchandiseAssortmentCategoryId>
<merchandiseAssortmentCategoryName>D21 Plywood</merchandiseAssortmentCategoryName>
<merchandiseSubordinateClass>

When i run this, only the category name is filled. the subordinateclass number is just blank.
I am creating Flex application.When enter data in data grid cell that time i want to check that cell value is less then 20 and if it not then change that cell's back color to red.

View 3 RepliesI have a Flex DataGrid where one individual cell needs to be rendered in a different way from others. Specifically, for one row of the grid, one of its cells should be hidden.
The DataGridColumn is set out like this in my .mxml file:

but that doesn't work - in fact it messes up the display in a rather entertaining fashion (one of the other cells in the row gets an extra checkbox.. I suspect it may be possible by using a custom ItemRenderer class but that seems like a lot of code overhead for a fairly simple case.
I have a datagrid in my Flash app whose data keeps updating quite frequently.On every update, I need to change the cell color of only those cells whose data has changed.That too, if the updated value is less than the older value then the cell color should change to RED else, GREEN.I have tried using labelFunction, cellrenderer, etc. But to no avail.By no means, I am able to access the present data in the cells to compare it with the new data.
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 a datagrid that is editable. I was wondering if it's possible to retreive the cell value after user edits the single cell.

I am using a datagrid in flex and need to render each cell with a different style.What could be the best way to set a style to a perticular cell in datagrid/advanced datagrid (flex)?
I think one possible option can be extend the datagrid and override the drawRowBackgroungd function. Apart from this can i use some custom item renderer or some property similar to label function of a series, there it used to return label here we need a style.
Is it possible to set the color for each individual cell in a datagrid, not whole row or column? How to do it? Which command should I use?
View 5 RepliesI have created a datagrid with 2 columns. The first one is the normal text data and the second column contains buttons for each cell. What I want to do is retrieve the text information when the corresponding button on the same row is clicked. How do I get this information? I am unable to use selectedItem because I do not want to select the correct row before pressing the button.
View 2 RepliesHave tried to figure out how this can be done - use this simple code to populate a datagrid with XML data in this format. What i want is a datagrid that will function as a gantt chart - with 2 different colors - just thought this might be a way to solve it. In the final XML there will be more than the 2 columns!

<item columnA="This1" columnB="1" />
<item columnA="This2" columnB="0" />

I have an editable datagrid with a dataprovider which is basically Numbers. Is it possible to delete a value? When I do it it puts a 0 in that cell but I really need an empty value, like a Null or a NaN whose are going to be cleaned later with a labelFunction. BTW I also need the cells to keep the 0 if needed to.

I have a Flex DataGrid, which has some columns, i had put a item renderer, which makes all the elements in that column hyperlinked, i have a requirement, where i need to see the type of user, based on that i have to either enable or disable the hyper link.
Is there any good way , where i can get the style properties at the cell level...?
I want to select information in a single cell from my DataGrid in Flex 3.
Specifically, I'm displaying three phone numbers per line and the user needs to be able to select one of those numbers, from any row, but not the whole row.
While similar to this, I am displaying the DataGrid to the user. The answer for that question was to manipulate the dataProvider, how can I know what cell I've selected in order to do that?
I have a flex editable datagrid mx:DataGrid and when I press TAB key, it changes to another cell when I am editing a cell.
I don't want it to change to another cell when I press TAB. How can I stop this behavior?
I have an AdvancedDataGrid that loads data from a web service. It only loads the top level stuff and then as you click the arrows it gets that data. All I want to do is to find out if some text is in one of the cells. I originally did this:
public static function assertTextInAdg(params:Object):Boolean{
// Gets the ADG
trace('youre in the assertTextInAdg function');
var grid:* = FPLocator.lookupDisplayObject(params);
trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);
[Code] .....
And then it fails, because it can't get the source, I think. I am completely open to other strategies and I have been stuck on this problem for 10 days now. This seems like it would be relatively easy. I have been going down a slightly different route. I am now trying to iterate through the HierarchicalCollectionView with a cursor. This seems to work. But, when I get the node I can't do anything useful with it... I have been looking for examples but so far they all stop at the point of getting the node.
public static function assertTextInAdg(params:Object):Boolean{
// Gets the ADG
trace('youre in the assertTextInAdg function');
var grid:* = FPLocator.lookupDisplayObject(params);
trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);

I am searching for something like CellClick event on Spark DataGrid, or something alike.
Is there something like this in Flex 4.5, and how to get the data from the clicked cell ?
1) Using the MouseEvent.CLICK listener, I can determine the row (and all of the values in that row) that was clicked, but I can't seem to figure out how to tell what column the clicked cell is in.
2) Is it possible (and if so, how) to assign a textFormat (or style) to just one column in a DataGrid?
I've created many grids and understand how to respond to a clicked cell but what I'd like to do is give the user a cue about which cells are clickable. An ideal solution would be for the cursor to react as it does for a button and turn into a pointing finger.

When I run this I get an error on the first click and any next click on a row will give me the cell data of the previous click (so I'm one step behind).
What should I do to get the data from the cell to show up in my text field?
