GridPanel - JS summaryrenderer accessing record data

[Markp11]

Hello,

I am wanting to combine the value from several fields to make up one of the columns in the Group sumnary of a gridpanel.

I have created a JS function but I am not sure on how I extract the values from the data parameter:

e.g.

var TollGateRenderer = function (v, params, data) {
         var l = 'Tollgate ' + <fieldvalue1> + 'some text' + <fieldvalue2>;
         return l;

     };

<fieldvalue1> and <fieldvalue2> are where I would like to extract a field value from the 'data' parameter, but I have not been able to work out the correct way to do these.

I am calling the function using <SummaryRenderer fn="TollGateRenderer" /> as part of the GroupingSummaryColumn.

any help would be appreciated.

thanks

Please mark this as solved, finally cracked it:

I need to use data.data.<fieldname> as in data.data.Tollgate_ID
