Continuing with exploring the new multi-file upload tag functionality in ColdFusion 9, this post will build on the previous post and add event handlers. We are able to work with 3 event handlers:
Back in beta, I had made a post on this new tag in ColdFusion 9. It creates a Flash interface allowing the user to upload multiple files to the server. A pretty easy way to achieve something powerful. Back in beta, there was also a bug with the funtionality. It was that ColdFusion was not automatically passing back Success, Failure messages. With the release now, that has been taken care of, so we can revise the beta code.
Have a look at the Demo
Lets take a look at how simple the code is
I hadn't looked at the Ext JS library in a while, but this weekend, I took a look at it with the idea of eventually building out a full CRUD grid using Ext JS and ColdFusion. It took some time, particularly trying to figure out the phantom records implementation, but its done now.
And as always, time to look at the code.
It has been a while since I made my last blog post as work has kept me very busy. Over the weekend I saw that a new jqGrid version had been released and that it contained in-built advanced searching (called multiple search). I also thought it was a good time to revisit my earlier blog post on a full CRUD grid and update it to 3.6 specifications.
This implementation uses the following jqGrid features:
View the Demo : this is all realtime, any updates made will be reflected in the grid.
Now, lets look at the code
I downloaded the jQuery UI library a few weeks back (should have done it earlier too). I started playing around with it, but work has been so busy did not get much time to look at it. Finally, found some time to do a basic tabs, accordians, sliders, progress bar demo. Its very basic, good start to learing how some of the things work.
The progress bar demo is probably the most complex one, so code for it follows.jqGrid 3.5 was released yesterday. It includes lots of good features, including a new rendering engine for faster loading. It also now supports jQuery UI ThemeRoller themes, so to start off itself you have access to variety of styles and can create your own easily too.
So I went ahead and created a demo that shows the grid in all these themes.

How I did this style selection switch, follows
Previously I blogged on getting a normal cfgrid running with ColdFusion. This post will look at expanding that to a full CRUD grid using ORM.
In addition to ColdFusion, I am also using jQuery and jqModalspecifically to display the modal boxes. Main reason being that I was itching to do some jQuery stuff.
Code follows.Over the weekend, I have been working with jQuery and specifically jqModal for a full fledged CRUD Grid using ORM. For some of the alerts/forms I was using jqModal to show them. Everything worked fine on Firefox, but IE8 had issues. After an hour or so of searching, I realized that I had faced a similar issue when working with jqModal on IE before.
The problem is that since I do not wirte a lot of HTML in my day to day coding, I generally omit the DOCTYPE sepcification from my pages. This causes interesting issues on IE. So, the solution was to specify the DOCTYPE and everything was working smoothly in IE too. My DOCTYPE specification that solved these issues was:
See the difference:
DOCTYPE NOT Present
DOCTYPE Present
Just a quick post about how to go about adding custom buttons to the cfgrid's paging toolbar. I believe this has changed from Ext 1.1 (which ColdFusion 8 implements) to Ext 3.0 (which ColdFusion 9 implements).
You can see the normal cfgrid here. It comes with no buttons, and it as such with a grid implementation it would suit us if we could show add/edit/delete buttons.
So, you can get your pretty icons and add some nice buttons to the grid allowing users to perform operations. I have one up with an add button.
Code follows
One of the exciting new feature in ColdFusion 9 is its ORM implementation. ORM in simplest terms allows us to access the database using objects, or in in even more simpler terms you don't have to write any queries for simple CRUD functions. To learn more about ColdFusion 9 ORM visit Adobe's ColdFusion 9 ORM Docs and Introducing ORM in ColdFusion 9 Beta.
This post will look at implementing a cfgrid using ORM. This will be first in a series starting from just implementing the grid to read data ending with a full fledged CRUD cfgrid with ORM.
