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.
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
If you look at Ext JS examples for 3.0 release you will notice a lot of (New) stuff. The 3.0 release includes a bunch of new plugins to the normal Ext grid framework. A couple of these plugins deal with rendering a different type of paging bar.
Note: The demos/samples for ColdFusion 9 will be a bit slow to load due to them being hosted on a cheap VPS server (the best I could do).
Out of the box, the normal ColdFusion 9 cfgrid has the standard Ext JS paging bar. A demo of the ColdFusion 9 cfgrid can be viewed here: ColdFusion 9 CFGRID.
We will now replace the standard paging bar with a Sliding Pager and a Progress Bar Pager in this blog post.
With the release of ExtJS 3.0 and the ColdFusion 9 beta I have been digging into the library more. One of the libraries for the grids that ExtJS Core offers is Numbering the grid rows on the current page. ColdFusion doesn't have that option, so I decided to implement it. It was quite simple actually.
Note: This was all done on ColdFusion 9 beta and Ext JS 3.0. ColdFusion 8 ships with ExtJS 1.1 and I am not sure whether the RowNumberer class was present in version 1.1 or not. Also, since we don't have a ColdFusion 9 beta host (or if there is one I haven't found it), you will have to do with screenshots.
So, here is how the grid looks (and this thing looks a lot better than the ColdFusion 8 grid)
With the recent release of ExtJS 3.0, I have been looking at the library again. I decided to do a simple Grid implementation using ExtJS. ExtJS is probably one of the best looking JS libraries out there out of the box and when implemented its extremely quick. The main issue as has been when integrading jQuery with ColdFusion was passing the JSON back in the proper format for the grid.
Have a look at the Demo First Here.
