Whoops, I missed the DataGridColumn types.. replace them with Object and you should be good to go with ADGs as well

I guess this is a rather late reply, but if someone else is wondering about a generic solution for DataGrids (and AdvancedDataGrids, hence the Object type of the grid input parameter since DataGrid and AdvancedDG don't seem to have a common superclass ). public static function exportGridToTSV( grid:Object, onlySelected:Boolean = true ) : String { var dataSource:ICollectionView = (onlySelected ? new ArrayCollection( grid.selectedItems ) : grid.dataProvider ) as ICollectionView; var headers:String = ""; for each( var col:DataGridColumn in grid.columns ) { if( headers.length > 0 ) headers += "\t"; headers += col.headerText; } headers += "\n"; var cursor:IViewCursor = dataSource.createCursor(); var data:String = ""; var item:Object; var itemData:String; while( cursor.moveNext() ) { item = cursor.current; itemData = ""; for each( var col:DataGridColumn in grid.columns ) { if( itemData.length > 0 ) itemData += "\t"; itemData += col.itemToLabel( item ); } data += itemData + "\n"; } return headers + data; } public static function exportGridToClipboard( grid:Object, onlySelected:Boolean = true ) : void { System.setClipboard( exportGridToTSV( grid, onlySelected ) ); } Cheers

Cool, thanks. I have a big project in the back of my mind that's going to be built in Flex 4 and rely heavily on context menus for the UI, so I'll be checking back! Thanks for the contribution!

Mykola Bilokonsky — Mon, 23 Nov 2009 06:35:11 GMT

Cool, that'll do it. I might consider breaking that into two methods (removePrompt(), addPrompt()) just because in the future if you want to build any additional functionality into that (ie serving up custom prompts for different input fields etc) then it'll be easier to tweak it. Just a thought, though. This is a solid contribution, thank you!

Thanks for the recipe Glen. I hope you don't mind, but I've got some suggestions to improve your post. You can get all image file types by specifying a pipe delimited list in the filter attribute. Check out Dan Vega's recipe: http://cookbooks.adobe.com/post_Multiple_cfdirectory_filters-16226.html If you use recurse with cfdirectory then ColdFusion returns all the images in subfolders as well. This means that cfimage tag won't be able to find the image to resize if it's in a subfolder and will throw an error. You can get round this by calculating the subfolder path. For example: The final thing is that the code will constrain images to always be 100x100. It might be nice to resize them so that they keep the aspect ratio. You could just specify the width or height attribute. Alternatively you could resize the image so that the longest side is 100px. Have a look at these recipes: http://cookbooks.adobe.com/post_Smart_Image_Resize_and_Crop-16359.html http://cookbooks.adobe.com/post_Resize_images_on_the_fly_to_fit_in_a_grid-16428.html

PaulH — Fri, 20 Nov 2009 08:38:18 GMT

aren't java property files (resource bundles) supposed to be escaped unicode while flex uses utf-8 encoded resource bundles???

http://cookbooks.adobe.com/index.cfm?event=showdetails&postId=16331

PaulH — Fri, 20 Nov 2009 08:35:47 GMT

yeah there are a few quirks in some locales w/this approach (for instance, in tr_TR cf probably won't even start and logs & scheduling often break in th_TH). if i have to serve multiple locales i really like leaving the server locale as en_US. and i actually prefer sessions for locales.

Nice component. I tried this and it rocks. It suitable for paging in hibernate orm. But how can generate the the page navigation such that it depends on the number of search result? if i have 100 result and 10/per page it would have 10 buttons and so on. As per my testing, when loading the screen when empty search result, the navigation does not update anymore. thanks. cheers.

Mykola Bilokonsky — Thu, 19 Nov 2009 11:04:11 GMT

looks good! I had thought that there was a way to do this with Array.pop() but I guess you can only ever pop items out in order? Anyway yes, useful tool and does what it is supposed to. This was actually the very first programming problem I had to solve in AS3 for a client. I was so proud of myself. :)

wasimSINGH — Thu, 19 Nov 2009 08:23:54 GMT

I've applied the same filter technique to the more generic ListViewCollection. However, beware of using XMLCollections. If there's no recognizable sequence in the xml data, paging gets thrown off. It may be related to getItemAt(); vut I'm not sure. As soon as I added an "id" field in the xml data (sequential), it worked. Also, if I added sequential numbers to the beginning of an xml node text , it worked. One solution might be creating a Model and use that as the go-between Collection types as needed. (using ArrayCollection for the dataProvider and XMLcollections to perfom xml-centric functions) Sorting by column throws paging off as well whether it's an XMLCollection or an ArrayCollection.

Did you ever find out a way of doing it in the transitions tag? I am looking for exactly this same functionality. I am surprised I have not found more about this on the net. Can it be done with Flex 4?

nightspade — Tue, 17 Nov 2009 13:30:10 GMT

it's a very good solution, but i found a little error on this code : var xml2:XML = XML(dataxlc.getItemAt(dg.selectedIndex)); xml2.selected = event.target.selected; dataxlc.setItemAt(xml2, dg.selectedIndex); displayValue = xml2.displayValue; dataValue = xml2.dataValue; type for xml2 is incorrect, it should be like this : var xml2:Object = dataxlc.getItemAt(dg.selectedIndex); xml2.selected = event.target.selected; dataxlc.setItemAt(xml2, dg.selectedIndex); displayValue = xml2.displayValue; dataValue = xml2.dataValue; just a little mistake. but the rest is ok. nice post!

Very nice! Here are a few useful functions: - Getpagecontext().GetFusionContext().GetStartTime() - what time will begin processing the page; - Getpagecontext().GetFusionContext().GetApplicationName() - show your application name; - Getpagecontext().GetFusionContext().GetApplicationPath() - show folder where Application.cfc / Application.cfm; - Getpagecontext().GetFusionContext().GetPagePath() - full path to page where this function is called; - Getpagecontext().GetFusionContext().GetScriptProtect() - show whether protection is set forms (returns array); - Getpagecontext().GetFusionContext().GetResponse().GetContentType() - return type of data pages, for example text / html; charset = UTF-8; - Getpagecontext().GetFusionContext ().GetResponse().GetCookies() - return an array of cookies; - Getpagecontext().GetFusionContext().GetResponse().GetStatus() - return status of this document - for example, "200"; - Getpagecontext().GetFusionContext().GetRequest().GetParameterMap() - return structure of all parameters in the URL; - Getpagecontext().GetFusionContext().GetRequest ().GetParameterNames().NextElement() - return in loop a list of all the names of all the parameters in the URL; - Getpagecontext().GetFusionContext().GetRequest().GetQueryString() - returns everything after the "?" In the URL; - Getpagecontext().GetFusionContext().GetRequest().GetRequestURL().ToString() - return full URL of the page where the method is invoked; - Getpagecontext().GetCurrentLineNo() - return line number in which the function is called.

William Hannah — Sat, 14 Nov 2009 07:18:22 GMT

You could easily create a serialization method on an object, or create a serialize function that was fairly simple using a for...in loop. As long as your objects aren't too complex, I don't think this would create much overhead. Back in AS2, I created a recursive serialization method that created and XML doc from an object. Since you're just creating a simple string, it should be pretty fast.

RonnieCR7 — Sat, 14 Nov 2009 06:06:43 GMT

To be more precise, Since im accessing the JSP file from EJB class, i.e, sending the data to JSP file to prompt user download, the connection btw Flex component, Button in this case, is lost. When i access the url of the action class, i get the download prompt, but when i click the button on the flex app, it doesnt produce the prompt. How shud i send the retrieved data from EJB class to Flex and then access the JSP file. What changes shud i make to the Struts.xml file. Currently the Struts.xml file maps the button functionality with the action class and the tag is set to the JSP file....

RonnieCR7 — Sat, 14 Nov 2009 05:10:18 GMT

Hi Jim, This post has been of a great help. Thx.. However, my requirement is slightly different. I send the data from Flex to a Java Class(EJB class). After i retrieve required data from the database, i send it back to a jsp file and im trying to prompt a file download which isnt workin. I should have actually sent the data from EJB back to flex and den accessed the JSP file according to your Post. How do i do that? My backend framework is Struts. So how shud i specify in the struts.xml file to return the data to flex and then access the JSP file?

Jamie Krug — Fri, 13 Nov 2009 18:36:52 GMT

Thanks for sharing, Paul! Readers might check out the docs for all the other little goodies from cfhttp as well as cfhttpparam (to set HTTP headers, cookies, form fields, etc.).

http://cookbooks.adobe.com/index.cfm?event=showdetails&postId=16511

Jamie Krug — Fri, 13 Nov 2009 18:24:01 GMT

Good stuff, easy, but powerful! You can also clear query cache from the CF Admin, if needed. You can also tweak the maximum number of cached queries that a ColdFusion instance will hold in memory -- this must be fine-tuned to suit your particular application(s). Holding too many can cause performance problems; too few may not be as efficient as it could be. Hopefully readers all know to always use cfqueryparam, but if you don't (do), remember that any variation of the SQL within the cfquery tags at all will cause multiple versions of the same basic query to be cached, instead of one.

Jamie Krug — Fri, 13 Nov 2009 18:19:19 GMT

Thanks, Kevin. A couple random, but related little tips to add for readers... It's worth noting that the initial "big" query (from the database) should be as small as possible -- only what you know you'll need in your query-of-query calls. You might be able to filter out some records with a WHERE clause, and it's always best to list only necessary columns in the SELECT statement (as opposed to SELECT *). Finally, it's also worth noting that using cfoutput with the group attribute can also be handy in this type of scenario. It all depends upon the specific use, of course. Just my 2 cents. Thanks again.

David Welch — Fri, 13 Nov 2009 09:13:21 GMT

This approach only works with VERY lightweight components, not anything requiring a SystemManager, as this is not inherited properly using this solution. The FocusManager is also omitted, which is required on most components. Adding a new one (i.e. viewer.focusManager = new FocusManager(viewer) ) seems to work, although I'm not sure it's a good method. Any ideas how to properly add the component above so that it has all the pieces?

I am very interested to try the above solution which is the answer to my requirement but I am not clear with the using of "FlxBillingDocument " in the for loop. Where do we get this Class. Please answer my question. Thanks in advance. -Lakshmi.

brett hannah — Thu, 12 Nov 2009 07:23:45 GMT

It's a nice idea but seems far to buggy to be of use. It works fine if the mouseTarget is indeed a DataGridItemRenderer but right click on any other part of the dataGrid and the contextMenu is still available but throws casting errors when selected. I'd be interested to know if you have an alternative approach which solves this problem. Is the only viable solution to have the contextMenu on the ItemRenderer itself?

Cool, thanks. Does this only work in AIR? FileReference and direct SQLLite interaction doesn't work in the plug-in player, right? If that's correct, and please tell me if I'm wrong, it's probably worth mentioning it somewhere in the post! :) Also, was this accidentally posted twice? Can I delete this?

Help! I am trying to WRITE data from Flex into SharePoint. Although this article talks about pulling data out of SharePoint, what about inserting or updating SharePoint lists or data from a Flex front-end?

I also have been working to create a solution to bi-directionally communicate between Flex and SharePoint 2007. I need to read/write data from a front-end interface of Flex to the back-end of SharePoint. I do not use BlazeDS as Java is not my language or environment, however, I do use C# and work in a microsoft-based company. Are there any helpful solutions or frameworks which assist connectivity between Flex and SharePoint?

I added the following ActionScript code to filter the ComboBox and display only one entry for each item in the list, in Alpha order. This assumes you have a DataGrid named "MainTable" and an ArrayCollection of data called "FilterData" [CODE] //Create the filterable header(s) [Bindable] protected var header:ArrayCollection = new ArrayCollection(); private var tempHeader:ArrayCollection; private var tempHeaderText:String; private var tempHeaderField:String; private var tempRow:*; private var tempRowText:String; private var filteredRows:ArrayCollection; private var filterSort:Sort = new Sort(); protected function createComboHeaders():void { for(var column:int = 0; column < MainTable.columns.length; column++) {//Step through each column tempHeader = new ArrayCollection(); //Reinitialize the ArrayCollection for each column //Make the Column Label the first item in the list tempHeaderText = MainTable.columns[column].headerText.toString(); tempHeader.addItem(tempHeaderText); tempHeader.addItem({separator:true}); //Create an array of items in the column filteredRows = new ArrayCollection; tempRowText=''; for(var row:int=0; row
