Open Source Datagrid

As promised last week (and reminded by a post on Remote Synthesis) here is the next piece of useful open source code.

CF Datagrid - it converts queries to a nice presentable datagrid which has support for paging, filtering and sorting.

We use it internally and it happily handles querys of around 100,000 records.

It is available under the CPL 1.0 and I hope you find it useful.

If you find any bugs or issues please post a note on this blog.

Show me the code! | Show me what it looks like!

Update: Added new zip file with build 22 of the datagrid. It includes the missing files.

Brian Rinaldi's Gravatar Looks interesting. What would be nice would be if you combined the additional features of your datagrid with the sortable table code of my sortable tables custom tag (http://www.remotesynthesis.com/blog/index.cfm/2006...) - which handles the proper sorting of string, date and numeric data types without page reloads :)

Mark's Gravatar Hi Brian,

It's something that I'd love to be able to do but I haven't found a nice solution to make it work yet. The reason it won't work is that in the interests of performance the datagrid handles paging on the server side. This means that if we put any client side sorting on it then the sort would only be sorting the available items instead of the entire query sort.

As I mentioned in the post one of our internal uses of it involves throwing a 100,000+ record at it and the datagrid handles the paging very quickly.

There could be a nice way to do it with ajax, but I need to spend a bit of time to get it working with a nice clean interface.

Cheers,
Mark

Douglas Knudsen's Gravatar was trying this out. seems something is missing from the zip file
<cfimport prefix="msg" taglib="/net/redbd/customtags/msg/">
fails. FYI

looks nice though!

Lucas Sherwood's Gravatar Looks like we missed those ones.

The cfimport statment loads our simple message handler (to bo open sourced soon) but I am not sure what the utility cfc has it it... Stay tuned for an update

Mark's Gravatar Hi Douglas,

Thanks for that - I did test it on my machine but forgot to remove the mappings so I had all the dependencies.

I've added a new file which should have everything that you need.

Let me know how you go.

Cheers,
Mark

Douglas Knudsen's Gravatar Ok, now we are playing with a full deck! Nice. One thing I will suggest is replacing this
<cfimport prefix="msg" taglib="/customtags/net/redbd/customtags/msg">
with
<cfimport prefix="msg" taglib="../msg">
This will make the code more portable.

Also, the cfimport tag is cool for sure, but in our case our customtags directories are not under the webroot. I switched to using the old-fashioned customtag call of
<cf_datagrid >

Ever see GridMonger?

I prefer a customtag approach you guys are using, but gridmonger has been around for a few years.

Mark's Gravatar Hi Doug,

1st suggestion is a very good one - I'll look at doing that.

For the second one though - our customtags directory are also not under the webroot - we have mappings set up for /net which allows us to map the custom tags in very neatly.

The Readme.txt should describe the easy way (slap it all in the webroot) and the secure "right" way which involves a non webaccessible folder mapped in via a CF mapping.

I haven't seen grid monger - I'll check it out though.

Keep the comments coming.
