jqGrid TreeGrid SubGrid rewrite, code cleanup, keyboard navigation, jQuery 1.5.x tests

February 25th, 2011

Hello All,

After rewriting the Search module we have made the hard decision to rewrite the other two modules TreeGrid and SubGrid.
The reason for this lie in the concept of how these modules currently load the data -i.e after inserting every row we bind the appropriate events. This concept is not effective when the data is relative big. In such cases the TreeGrid throw a exception. Now we want to correct this problem binding the events at once.

Again with this we do some structure changes in the code. Lot of not used modules like grid.postdsata.js and grid.columns.js will be not more supported. They will be included into the download and moved to plugin directory. Also we have created another module named grid.addons.js. This module contain methods that will be no more supported. The full list of the methods will be know after a week. We have done some changes in GitHub, so you have a idea what we do.

Another good news is that we have realised (under development) a keyboard navigation in the Grid and Tree Grid. This will make jqGrid one of the best grids.

From today we begin intensive test with jQuery 1.5.1. If you encounter problems with this jQuery release please post it into the form with code example and data. Only these posts will be answered and eventually fixed.

As usual – any questions, comments, anything – is welcome. We are always listening and trying to improve.

Kind Regards
Yours jqGrid Team.

    The response you give me is not correct.
    I have defined a grid with these 5 fields and with some formatting get the original response string from you.
    Also you tell me you have 5 fields, but in your response there are more than 5 fields.
    Please send at may mail a real test case so that I can see what is, otherwise I can not help

    Regards
    Tony

    Hi,

    You say that keyboard navigation is in development – do you have any more detail?

    When do you think it will be out?

    “we have realised (under development) a keyboard navigation” — I believe you meant “we have started to develop a keyboard navigation module” or something like that.. the verb realise means to become aware of something :) where are you guys from? great plugin for jQuery btw, I’ve been using it for almost 3 years and it’s been a success.
