Flex :: DataGrid Change Value Based On Another Value?
Oct 4, 2010
I have a DataGrid in Flex, with one column a checkbox and another a numeric value. When the checkbox is clicked, the numeric value should change, either to 0 if the checkbox is unselected, or to a pre-defined minimum value if the checkbox is selected. Here is the code I have:
<mx:DataGrid x="0" y="45" width="272" height="525" dataProvider="{dp}" variableRowHeight="true" editable="true" id="equipmentDG" verticalAlign="middle">
<mx:columns>
<mx:DataGridColumn headerText="" headerStyleName="gridheader" width="20" dataField="included" editorDataField="selected" rendererIsEditor="true">
[Code]...
The value updates in the data (I can see it when I close and open the dialog this is in), but it doesn't update instantly in the data grid. How can I make the value visibly change as soon as the checkbox is clicked?

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.

I have a datagrid with an location and a list of activities Birdwatching, Boating, Camping. The datagrid is populated based on either a simple yes or no if the activity is offered at that location. I want to replace the yes / no with a separate image for each activity. I created a imagerender and I'm able to get the image to change but only to the birdwatching image. My question is, how can I get it to loop through that datagrid and display image according to the value?

I've search all over today trying to find how to do this, and not being familiar with actionscript is starting to catch up to me. What I would like to accomplish is: I have a list of messages in a Datagrid coming from a dataprovider in another class, which in turn gets them from our Oracle DB. I need to all the user to set a visible state on the message, and then filter that out of the datagrid with the click of a button. I have the check box for hide, and it sets that value into the database. I can't figure out how to get the filterFunction to work with an array collection when the filter parameter is within the row data.Here is the code
public function filterResults():void {
modelLocator.notification.messageList.filterFunction = filterRows;
modelLocator.notification.messageList.refresh();

i have a datagrid which contained several items,when i click one row, a panel will show,however, if i have already selected one row and then click some blank place, this panel will also show because there is already a selecteditem,which will be a problem. Then i change this click event to change event, however, there will be another problem, which is if i click the same row, nothing will happend. so is there any better idea when i click a row, a panel shows and when i click the blank place, nothing happened.

Can we change the width of the datagrid column dynamically by clicking on the border of the column in order to display the complete string which is too long to be displayed and needs to be scrolled ? If so, How ?
Also, how can we ensure that the column width changes dynamically based on the number of characters / length of string; since many a times the data is too long to be displayed. Can we set the column width to take the length of data into consideration before displaying onto the datagrid ?

It seems like there are various hacks out there to change the background colour of the row of a datagrid but all of them seem to happen at render time.See: http:[url]....I have a datagrid where I need to change row colours to red then back to normal frequently based on changes to the bound ArrayCollection. So I'm looking for a way to change the row colours dynamically.Obviously as the changes are happening frequently it would be nice if changing the background colour of the row wasn't an expensive process.

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 have a custom component ExpandCollapseMenu that extends SkinnableContainer.This component can have state "normal" or "expanded".Inside this component I have buttons, with different skin based on ExpandCollapseMenu's state.This works fine when defining the buttons inside ExpandCollapsMenu's skin class:
<s:Group id="contentGroup" top="20" left="10" right="10" bottom="10">
<s:layout>
<s:VerticalLayout/>
</s:layout>

I 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:
[Code]...
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 an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).

I am using the flex datagrid to allow the user to edit some data. My update process relies on a CollectionEvent of type update. Basically I catch this event package the values and update the database. However, if the user edits a cell then moves to edit a cell in the same row the value is updated but a collection event is not fired. Only when clicking out of the row the event is fired. Has anyone had experience with this. I have heard the datagrid is a little quirky is this one of those quirks or am I doing this all wrong?

I am using a singleton class (popup, which means it doesn't forget the last used variables) which contains a datagrid. I am making various columns visible/invisible, setting the widths and headers in accordance to data received from a database call. Everything works fine except that when I put the breakpoints before and after the point where I change width of columns, I do not see the change in width of datagrid at all! Instead I see some values totally out of sync as widths of datagrid column! However, since it is a singleton class, the next time I call this popup, I see widths which I did set up in last call.
I must be messing up in calling the setWidth() function (which is my custom function which changes the width of datagrid in action script). What should be the point where I should call this function? I tried in creationComplete, show and in the setter of dataprovider.

how use a button (or movieclip) to filter information out of a datagrid based on an external XML document. For example, say, the data were types of fruit along with their corresponding prices, but the user was only interested in the price of apples. To see only those records or rows with apples and the corresponding apple prices, the user would press the "Apples" button.
Creating the datagrid seems pretty straight forward, it's just the second part that's stumped me. Whatever the answer is would seem to go at the end where the "trace" is now. There seems to be many, many Web sites that sort of touch on this subject.I typed of the following from memory (I'm at work now), but I think this is pretty much what I have so far.
import fl.controls.dataGridClasses.DataGridColumn;import fl.data.DataProvider;
var food:XML;var urlLoader:URLLoader;var urlRequest:URLRequest = new URLRequest("food_list.xml");urlLoader = new URLLoader();urlLoader.load(urlRequest);[code].............

I 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?
package components
{
import mx.containers.HBox;
import mx.controls.CheckBox;
