Oct

Web 2.0: 

We have been using Crystal Reports for our Travel CRM with good results for a few years now. We use a completely custom ExtJs based experience for Report viewing which includes a custom user interface for entering report parameters (see screenshot below for an example) and a custom toolbar for managing report navigation and exporting etc (I had blogged about the toolbar earlier here).

ExtJs 3 - Normal looking buttons in toolbars

Aug
09

Seems like ages since I last did any serious blogging, feels good to be back. That too with an interesting solution to a common problem with ExtJs.

I have often seen end-users complain about non-intuitiveness of buttons in ExtJs toolbars. They simply look like static labels, not clickable buttons until you hover over them.

Sometime earlier, I wrote a blog post demonstrating a Ticker component for ExtJs to which items can be added dynamically (here). The client for whom I originally wrote that Ticker component changed the specification recently, now requesting the ability for the ticker items to stay on screen for a configurable duration of time.

I yesterday did a very interesting thing, integrating ExtJs with the excellent iScroll 4 script from Matteo Spinelli that would make my ExtJs containers intuitively scrollable on Touch devices (especially iPad) giving them a more native scrolling feel.

ExtJs and Ext.Net - Creating Ext.Net server components for custom ExtJs javascript components

Aug
08

I think all of us would agree that Ext.Net provides too good (and a bit complex) ExtJs and ASP.NET integration.

In addition, it provides own custom components that are useful (e.g. MultiCombo, Linkbutton etc).

And on some inspection, the request seemed to be reasonable.
