kendo posts

We recently acquired licenses for Kendo UI at Cogneato. We have plans to use some of its widgets, most notably the data grid and window, heavily in the admin interface for the new CMS we will be building. We figured that the time we save from not having to build similar widgets ourselves would be well worth the hefty license costs.

Troubles

We have made use of the window in a few sites so far, and the grid on alpleaders.org. I have found that for both widgets, it has helped to build a sort of wrapper around them. The wrapper helps normalize configuration and handles some things that we want to happen for all instances. Some of this was related to problems we ran into with the widgets or features we wanted that weren’t built in.

For instance, the data grid has the ability to be filtered per column client side. A ‘row’ mode provides an input with autocomplete for the values in that column. If you want to use a different mode, however, there is no built in autocomplete feature. You have to create an autocomplete widget for each column. Attaching the same data source as the grid uses results in the same number of items in the autocomplete as there are rows in the grid, meaning if 30 items have a ‘State’ of ‘Ohio’, the autocomplete will show ‘Ohio’ 30 times. I set up a helper to build columns and automatically create a new data source with a single instance of each value for the items in a given column. I’m not sure why, since they already built their own logic for the ‘row’ mode, they couldn’t make that an option for other modes.
