Hi, thanks for your support.
I am using igGrid with wcf services and data returns in JSON format, data is loading when it is around lessthan 2000 rows if more than that the load is failing and getting The remore request to fetch data has failedg.
does anyone have example load on demand with paging, sorting, fiter or loading all data in grid?, my page count is 25.
appreciate if you provide with example.
Hi,
I suppose error that you get is probably thrown by your server side - you can inspect what the WCF returns(e.g. you can use DEV tools if you are using IE, FireBug in Firefox, etc.)
For huge data you can enable remote paging, filtering, sorting(and what you need). Also from 13.2 we have implemented Load On Demand for flat igGrid. This means you can set how many records to load initially and when you scroll to the bottom of the grid new request is made to the server and new data is loaded http://www.igniteui.com/grid/load-on-demand
You can check this forum post for implementation of remote paging in the igGrid http://ko.infragistics.com/community/forums/t/81433.aspx
Thanks,

thanks Bob for your support, this has been tested already no differ with or without virtualizatin options getting same error when it has more data: The remote request to fetch data has failed: (error) undefined.
maybe check out virtualization in the meantime. It stills loads all the records in the client's memory, but does not render all records to the grid at once.

I'll keep you posted if I get further...

Hi Bob, actually I need remote paging, filter, and sort. tried several ways but no luck. In my database I have 18000 rows. wihout any filter my dataset gets all rows and it fail to load. if there is 2000 rows works as expected.
rather than wasting time try LoadOnDemand for data and check remote filter, etc. but I am not sure this also works 100%, tried simialar way of hierarchal grid but still failed to load data..
Let you know if it works.. also let me know if you can implement it through some other way..
thanks
Vijay.
You're saying "load on demand", but do you mean "remote paging" ? The Hierarchy Grid has load-on-demand for example (http://ko.infragistics.com/products/jquery/sample/hierarchical-grid/hierarchical-grid-load-on-demand), but not the igGrid as far as I understand.
I'm also having some issues trying to figure out the proper way to implement Remote Paging, but I'm not getting any responses for a week now...and no real helpful examples without using the ig wrappers.
