I have a DataGrid, and what I would like to do, is when a user clicks on a row to select it, check a certain condition, and if it's met prevent the row from getting selected and keep the old selection intact.
View 1 RepliesSo the real problem is the lack of an onReleaseOutside function. I found some examples of how to bypass this during a drag function but it was not applicable for a text input.The problem is that when a user selects some text in textinput and mouses off the application area and then mouses up, I'm getting a problem that the textinput keeps thinking that the mouse down is actively selecting text in the textinput and continually overwrites the characters being entered in the textinput. in the search bar of the live store on the page, type some text, then highlight it all and don't let up on the mouse until you are outside the store.I finally hacked some junk together so I can tell if the mouse goes off the stage using some code like.
var x = stage.mouseX;var y = stage.mouseY;if(x < 0 || y <0 || x >stage.stageWidth || y > stage.stageHeight)I'd like to just make the textinput stop thinking it should be highlighting text so that even if the user scrolls out of the applet and mouses up that the text input still overwrites what is in the search bar and functions as normal.
I have 2 questions: 1. What would be the event to capture the fact a scroll has taken place in a datagrid?
2. Does anyone have any suggestions on how one could disable the scroll of the datagrid when a user clicks a cell then drags out of the datagid?
I have a Tree component that's used as a navigation menu between different 'pages'. When the user clicks a certain option in the menu, I switch the 'page' by switching between State components in my application. The thing is that when the user indeed clicks an option in the menu, I want to perform a validation of some of the information in a certain component. If the validation fails, I show an alert, and I'd like to prevent the navigation to the other page. One part of this is simply not changing the currentState of the document, but the tree component still goes on with the change event, and the result is page A still being shown on the screen, whereas the selected option in the tree is page B (to which the user wanted to navigate, but failed since some of the information wasn't valid).
I tried to figure out how I can cancel the change event on the tree component itself. The thoughts I had didn't quite fit nicely:
I searched for a slightly different event (such as 'changing' or 'startChange') on which I can call the stopPropagation() method (since the regular 'change' event is not cancelable), but none exists for the Tree component.
I also thought about always saving the current option that's selected in the Tree component by myself, and when the validation fails, I will set the Tree's selectedItem to that saved option. That's also ugly because such an action will raise another change event on the Tree, thus another change to the States components, and another population of the page in which I'm already at. That's something I really don't want to do.
I also though about using a different component, such as Menu (and I also found an implementation of a vertical Menu), but that doesn't even seem to help. The same problem will exist there.
There must be a best-practice for preventing a change process to commit!
I have a flash element in a page that load a chart based on some complex queries that can take up to a minute to load. I call the query with this code :

chartData.addEventListener(Event.COMPLETE, onLoaded);
chartData.addEventListener("httpStatus", onHttpStatus);

I have an editable grid and would like to update values based on the edited cell and I am doing this in the itemEditEndHandler such that when they finish editing a cell I update other cells that are dependent on it. the only problem is in the itemEditEndHandler the new value has not registered yet. If I try and get the value of the cell i find that its still giving me the old value and not the new value that I have entered.
View 2 RepliesI receive my parameters as 1's or 0's to fill a datagrid full of checkboxes. The funny bit here is that the checkbox control recognizes them as booleans! But then my checkbox control has a change property in which these numbers are converted to "true" or "false".How can I convert this changes to ones and zeroes again to send them back to database?I believed the ByteArray function "writeAsBoolean" would work, but I forgot the rest of the values inside the datagrid are kept as numbers. So that function will not recognize them and my webservice will ignore them, failing to write the data.

View 1 RepliesMy datagrid is filled with data from an Oracle database. The datagrid refreshes after 1 min. After that, I lose the selected item. I want to avoid that.

View 1 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.

Back again with another Flex question. I have an XML structure like...
[Code]...
Now I got his displaying on my grid by saying dataProvider=XMLListCollection... What I want to do is on selection of a row, check if it has "Address" tag, if it has display the other grid, else hide the grid.
I have a datagrid with 5 columns. The first column has checkboxs and rest four columns have data from the dataProvider.
I have two relating issues: First: I want the row to get selected when I click on a checkbox, or if i click on multiple checkboxes, every row should stay selected in the datagrid for whose checkbox is selected.
Second: If a row or multiple rows are selected, the corresponding checkbox should get selected too.
My code is given below:
<mx:DataGrid id="dg_trashContent" allowMultipleSelection="true"
verticalGridLines="true"
dataProvider="{trashDataProvider}"

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?
View 1 RepliesI have a DataGrid and I set the DataProvider to my data. When my data changes the DataGrid loses the selected row and the scroll bar jumps back to the top. How do I maintain the selection and scroll position?
View 2 RepliesI'm working on my first ever AIR application with flashbuilder - just so you know. I've bound a mx:DataGrid component to a DataProvider which is a mx:HTTPService fetching an xml file with items. To keep the data up to data I'm polling the webservice on a given interval.
My problem is that I loose the currently selected item in my DataGrid when the data is updated. I've tried to save the DataGrid.selectedIndex and set when the data is updated, but I'm not sure when to do it?! The closest I've come is to restore the index when the updateComplete event of DataGrid is fired. This works, but the selection first fades away and then fades in - not updated soon enough. So what is the best way to keep the selection? (only one selected item at a time) And as a side question: is there a convenient way to only update the data when it has actually changed?
I have a datagrid.In this datagrid I have a combobox item editor. This datagrid also has multiple columns where a user inputs numbers in each column. These numbers are then calculated by formula where the sum is posted in the "total" column. In this combobox there are two options for the user to choose from and each option has a different formula for calculating the inputted numbers. What I want is for when a user chooses "option 1" one formula is used to do the calculation, when "option 2" is chosen by the user then formula two is used to the calculation.Here's an example:
Combobox Option 1 (formula 1) is chosen by user = (Column2 - Column1) x column3 = "total" column
Combobox Option 2 (formula 2) is chosen by user = (Column1 - Column2) x column3 ="total" column
I realize you would use a conditional such as "if else" statement, but im just not sure how to do it. I've been trying to implement this for a while with no success.
i have an array list of data which i am showing in spark data grid. once i select an idem and click on a button that i have linked with datagrid it adds a panel on screen. I want to disable this selection i-e to tell that this item panel have already been added. Any ideas how can i do that?
View 2 RepliesI have a custom skin applied to a Flex 4 spark datagrid. One really annoying issue I am having is finding the ability to override or change the selected row border color. I was able to set the selectionColor just fine but the border is still the default light blue color. I need it to be yellow.
Anyone know where I can find this style or override this border that is being set when selection happens within the skin itself.

View 1 RepliesI have a spark datagrid on a mobile application, I set the

How can I add the touch dalay before select the index, so if I scroll the grid the selection won't change, and it change only if I press the item without scrolling?
I have two datagrids:

I tried a lot but couldn't understand it.
If you have a DateChooser control next to a text control and you left click your mouse to select the text then continue holding down the mouse button and letting the mouse button up while over the datechooser control, the selectedDate value changes to the date you are hovering over. I have users that are having issues with this and it happens unintentionally because of the proximity of the two controls. I cannot find a way to stop this effect. Basically I would want the selectedDate to only change if the user actually clicks the calendar control ie. mouseDown or click. Calling functions in those events do not change this behavior. I need a way to disable the control from changing the date on the mouseUpEvent (I think).
