Jun 6, 2011My 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. Consider that it's quite possible that there is new data after refresh, so the selected index may no longer appear in the datagrid after a refresh.
View 1 RepliesActionscript 3 :: Flex - Selection In Flex Datagrid Does Not Pass The ValueObject To SelectionChangeHandler Function
Aug 11, 2011I 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.

Flex :: Blue Selection Of Datagrid Row Programmatically?
Jan 28, 2010I 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 2 RepliesActionScript :: Flex - Keep Selection When Refreshing Datagrid
Oct 20, 2010I'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?
Flex :: Combobox Selection Inside Datagrid?
Mar 1, 2011I 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.

Flex :: Set The Selection Border Color In Spark Datagrid
Jun 29, 2011I 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.

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 RepliesFlex :: Flash Fullscreen Background Image
Feb 4, 2010I want to load an image into the background of my Flex app. However, I am wondering about a few things, and have a few contraints.I want it to be much like the way it's done with CSS. See this example of fullscreen background images with CSS.It is very important that there is no white-space (background colour) showing behind the image, and that the image is not stretched. This would mean some of the image would be cut off. This is absolutly fine. Actually, the first five points in the bulleted list on the linked page above are all exactly what I am after.I am relitivly new to the Flex framework, but have a strong AS3 background. So I can do this easily with actionscript using a mask, stage.width/height, the stages RESIZE event, and a little bit of Math. But I am wondering what would be the "Flex" way of doing this?I don't want to narrow the answers, but would I create my own component, that extends canvas, that I put behind all my other content? Or to I set some property of the application?

Flex :: Dynamically Change Background Colour Of Datagrid Row?
Mar 7, 2010It 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.
View 2 RepliesFlex :: Transparent Background On Spark DataGrid Headers?
Jul 14, 2011I almost got it, but the part that's giving me trouble is making the header background transparent. I am making a custom MXML skin based on the default Spark DataGrid skin. I tried setting the contentBackgroundAlpha to 0 on the columnHeaderGroup and the headerRenderer, but that didn't work. I tried setting visible to false for either of those, but that made it so that the text didn't show up either, so that didn't work. There is no setting for backgroundAlpha in either of those two, so I'm not sure what else to try.

ActionScript 3.0 :: Peel Button Animation - Hovering Above The Background When The Mouse Is Finally Over The Button?
Jun 22, 2009So I had an interesting request from a client the other day. Basically, he wanted the button (which looks like a sticker) to peel off as the mouse approaches the button. So from the outside of the hover point, it would peel a little. As the mouse gets closer, the peel animation would peel more (or less, depending on the mouse position) until it is 'peeld' off the page and sort of hovering above the background when the mouse is finally over the button.
Does anyone know of some custom classes that might achieve this? It seems like it would be making use of the new 3D in flash10, but I haven't had much time to experiment with 3D in flash.
Flex :: Use Custom Background Skin On Datagrid Header For Currently Sorted Column
Apr 26, 2011I use a flex mx:datagrid. I can set the headerBackgroundSkin to specify a skin or a picture to be displayed in all datagrid column's headers and it works just fine !
The problem is I can't find any way to specify a custom skin for the currently sorted column (doesn't matter if the sort is asc or desc, this is just to show the user which column is currently sorted).
I also tried to create a custom headerRenderer for each column but it is quite complicated and doesn't work very well.
I have been looking for the solution for a while but I can't find a good approach to do it. It sounds like a very basic need for me...incredible it is so complicated to achieve with Flex !!
I noticed someone was looking for the same thing few years ago but without success... [URL]
