How can I get the entire colModel for a jqGrid element? I've gone through the source code a bit and also played around with some tests, but nothing seems to return the actual array.

Get the jqGrid colModel
jqGrid highlight the new added row
Is that possible to highlight the new added row in jqGrid. The highlight effect is something like this http://docs.jquery.com/UI/Effects/Highlight

Setting the content-type of requests performed by jQuery jqGrid
I am using the latest version of jqGrid : 3.6.4
This seems like a simple problem (or at least it did before I spent a few hours on it):

Hidden Columns in jqGrid
Is there any way to hide a column in a jqGrid table, but have it show when the row is edited in the form editor modal dialog?

JQGRID: any easy way to implement undo on excel like jqGrid implementation
Just to give little update before putting my question....
I've been able to come up with some additional features on the jqgrid that I'm using (after going through many forums) including: copy-paste back and forth from Excel to jqgrid, edit cell on keypress and dblclick, copy and paste multiple cells from one block to another on the same grid using mouse selection (from here Using Javascript to 'sum selected cells' in IE6 )
Most of the copy paste features works on IE only as of now. I save all the changes together on "Save" button click so all the updates on the cells are on screen only until user hits the "Save" button.
Although, things are still in flux right now, I'd like to have the implementation design on paper now than later. I'm looking for an easy way to UNDO only the LAST change. I've been thinking of using jQuery's "data()" and "removeData()" methods to implement this but if there is anything already existing in jqgrid framework that would help, I would like to know. Any suggestions??

Many Thanks in advance!
Edited on 9/13: This is my first use of JQGrid. I'm using ver 4.1.2. I spent few weeks to put together the excel like grid and the biggest challenge was to find the right information on how to use JQGrid. My current setup has lots of ajax updates and image galleries and use of jqgrid formatter but what I've put here is the main code to be able to use JQgrid with server side paging, excel like copy-paste and demonstration of few other features on jqgrid. This is just my way of giving back for all the help that I got from this community.
For people who just jumped to JQGrid, you will soon find out that there is some challenge to using Textarea in jqgrid. you can find some solutions here .

Multiple jqGrids fires ajax call for every jqGrid on page
I have three grids each has a unique: pager, ID, and wrapper. These grids are hidden by default and show upon selection of a dropdown box. At page load, before anything is selected, jqgrid makes three ajax calls for its data, but after debugging it appears that each grid makes three calls, one for each of the grids on the page.

JqGrid - Simple Searching With Additional Field(s)
i am using jqgrid and have simple searching enabled. i am wondering if there is a way to add an additional item in the select list of fields that does not exist as a column in the grid. i would call it something like 'Any Field' so i could search on any of the fields and then handle that outcome server side.
