Javascript error on tab out of a row Posts

May 7, 2014 at 6:09 am Javascript error on tab out of a row #54082

Participant

I have loaded a grid in my local server by taking the code from the “http://www.jqwidgets.com/jquery-widgets-demo/demos/jqxgrid/index.htm#demos/jqxgrid/createremoveupdatedata.htm” and the grid was loaded successfully.

I have added the below additional properties to the grid :

editable: true,
editmode: ‘selectedrow’,

I have reloaded the grid again and when I click the row for a second time the whole row will become editable. I have changed a cell value and clicked some where else ( out of the row ) and I am expecting the ‘updaterow’ method defined in the source should be called, but I am getting the following error.

Uncaught TypeError: undefined is not a function jqxgrid.edit.js:471
a.extend.endcelledit

Please help me in solving this issue.

Thanks

Shankar

Hi Shankar,

Sorry, we cannot replicate this with ver. 3.2.2. Do you use the same?

Here’s my test code:

Hi Peter

I am using 3.2.2 version only, but it seems I have accidentally corrupted the jqxGrid framework js files ( provided by JQ Widgets team ) and the problem is solved after re-copying fresh ones.

Sorry for the trouble.

Thanks a lot for quick response.
