jqxgrid jsonp and observable array

[jonnoParticipant]

Hi Folks,

I want to show changes to data on the jqxGrid at an arbitrary interval, i.e. every 5 seconds.

The entire dataset is retrieved remotely using ajax jsonp.
This data is to update the jqxgrid and highlight changes.

I checked out observable array but i’m just not sure how to do it.
I’ve checked the examples on this site, the methods don’t seem clear to me.

Any help greatly appreciated

Hi jonno,

jsonp and observable array are different data sources which cannot be combined. If you want to update the Grid per interval use its updatebounddata which will make a new AJAX call to your JSONP data source and will update Grid’s data.

Hi Peter,

I like the idea of detecting changes in the data for the grid to render where required.
What data structures are required to use observable array?
Could i continuously convert the json data into a local array for observable array to use?

Hi jonno,

You can get the changes by binding to Grid events such as cellvaluechanged. It’s better to keep the things simple i.e bind the Grid to JSONP instead of binding something to JSONP, then converting that something to observable array and binding the Grid to observable array and then updating the server in some other format, but that is just an advice.
