Advanced Paging and Filtering in Flex Datagrid
Well there are some blogs and sites where you can find an example about paging on a datagrid or advanced datagrid.
There are also a lot of blogs about filtering on flex datagrids or flex AdvancedDatagrid.
But… there are no examples about paging AND filtering on flex Datagrids or Flex AdvancedDatagrids.
Now there is !
When I was working on a sollution for paging a big amount of information in a flex Project the people I was building it for asked me if it was possible to keep the filtering functionality in.
At first I thought it was not possible. But….. after a good evening at trying, coding and testing at home I had succes and paging and filtering on a Adobe Flex Datagrid (or AdvancedDatagrid) is possible.
There is only one big issue, on a big amount of row’s it can become slow.

this is nice! how can we achieve this if the data is coming from a webservice?
thanks
Here you can find an example: http://blog.flexmaniak.pl/flex_i_php/pagination-d…
Great but where is the filtering ? By the way, 1000 items should not crash the app. I worked with datagrids with over more than 20.000 items. Tru PhP
I didnt mean 1000 of items but thousands like 100 thousands or even more.
Filtering is not implemented yet, Im working on new – better – version (more flexible
).
Im just trying to port extJS DataGrid to Flex
Unfortunately I dont have much time lately :/
It depends on how you want to get the data. I you get all the data in one single call you can use this script. If you want to recall on paging or filering you will have to do some recoding.
Can anyone post a Paging example on a advanced datagrid which has grouped data..Will be of great help..thnx in advance
Please look at http://www.flexicious.com http://www.flexdatagrid.com. Its a component that handles server and client paging in addition to a lot of other features.
How do i change data-provider form for loop become my own xml data file.
Hi,
Fantastic app. I'm struggling with one additional item and wondering if you would have any idea how to:
1) use an external xml file
2) reload that same xml file every 5 minutes
Thanks again,
Todd
Does it read data from the first page only and when you click to go on the second page, it load the query for the second page? im looking an example like this. anyone?
No, that would be only possible if you would do a server side filtering.
Thanks for the great and simple code on pagination compared to others out there, you rock
is there a way to add a button in a column to the datagrid rows which takes an action with the row data? Thanks
Like an itemrenderer ?
Thank you very much for the awesome share. I had spent almost one night to build a paginated advanced datagrid, but it didn't work. After checking your code, I found out my error, and as a bonus got data filtering
Thanks again. keep up the good work
We've added a whole lot of features to our grid – Please look at http://www.flexicious.com Filter, Paging, Footer, CheckBox Selection, Print, Print Preview, PDF Export, Excel/Word/Html Export and preference persistence.
So now that I've put this "advertisement" of flexicious here the second time on my blog, it's about time I get a free version, right ?
Hi
Can't download the code?
please
can you send me by e-mail?
Thanks
Oh I totally misunderstood.
You can find the code here : http://www.iamboredsoiblog.eu/flexfiles/paging-fi…
filterVANm() Where's the function that does the filtering? THAT's where I'm stuck. InitApp(), too.
???????????
The MXML reveals nothing about how to do the filtering.
Or I'm dense, since everyone else is raving about this post.
all the functions are in globalscript.as file.
its nice and good work. ok. i have a problem here to exprot the dataGrid as it into pdf file. plz help me if anyone know about its.
if i wanna look forward from the back of the data,
i think convenient
Pretty much what I was looking for. THanks for sharing it
rs.result.setDeliveryMode(mode String, pagesize Number, prefetchPage Number)
setDeliveryMode is a very very simple method to do client data paging (lazy loading) in Flex 2. I don't know why it is no longer supported in Flex 3. Does anyone know about this?
Really great job. It helps a lot to every one who goes for pagination in Datagrid.
many many thanks
can i hv source for this?
thanks
greattttt
Many thanks. Can we put the code of globalScripts.as in some class? I tried putting it but didn't work. I was getting an error Data binding will not be able to detect assignments to "…" while providing the dataprovider in the linkBar
Actually this solution sucks as it sort only visible page… It's done almost out of the box. Sorting whole collection is a challenge.
Wow, thank you very much for that great response. As you can see this Article created like more than 2 years ago. I think there are much more and better sollutions for this.
However, You\’re not giving us one. You just bash on it.
Great pagination system. I had one that no matter how much data you had it will still say 10 pages of data. I replaced it with your system and it works.. still have a few bugs to work out but it's still works for the most part. I created my own filters functions because I have so many different ways that the users need to filter. I used returned data from HTTPSERVICE using PHP Json Arrays. I know this is quite old but it still a useful article
Thanks a lot ….
Really great work.hats off to u.i have been trying this more than a day.thanks yaar.
