JSON and jqGrid. What is “userdata”?

It is very easy to explain. The server produce a data which will be used to fill the grid. The data can be paged.

So in the URL send to the server we can find rows=10&page=2 which means "give me the second page of data, when the page size is 10 rows". These additional parameters will be added to the main url "server. Php?

Q=2" defined as one of jqGrid parameters. The server give back 10 or less rows. In case of http://www.trirand.com/blog/jqgrid/server.php?q=2&rows=10&page=2 url the server gives back only 3 last rows (from the total 10).

That seems to be the sum of the columns 'Amount' 'Tax' and 'Total' on the second paginated page assuming that the grid is ordered by the 'Inv No' low to high.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
