Retrieve bound data from the clicked row or cell of a nested grid? Posts

I finally have my version of the nested grid using the demo as an example, but I need interaction when the users clicks a row of in the nested grid.
It seems I only know how to pull the main grids’ data, can you help me get data from the nested grid.

Using the demo as an example, I would pull the main grids’ data like
$(“#jqxgrid”).on(‘rowclick’, function (event) {
var rowindex = event.args.rowindex;
var mgrid_data_record = $(“#jqxgrid”).jqxGrid(‘getrowdata’, rowindex);
var nav_id_clicked = mgrid_data_record.ShipAddress;
};

But how would I pull something like ShipAddress?

Hi Gecko,

At the point you initialize the “nested grid”, bind to its “rowclick” event and in the event handler you will be able to trigger its clicks.

Peter thanks for your time and your reply but could you please expand a bit?
given the code for nested demo:

I assume that you are talking about putting in the var initrowrecords but if you could provide the actual syntax to get the ShipAddress for that row when rowclick on the nested grid that would save me hours of trial and error.

Hi Gecko,

The below code shows how to bind to an event of Nested Grid:

        var initrowdetails = function (index, parentElement, gridElement, record) {
                var id = record.uid.toString();
                var grid = $($(parentElement).children()[0]);
                var filtergroup = new $.jqx.filter();
                var filter_or_operator = 1;
                var filtervalue = id;
                var filtercondition = 'equal';
                var filter = filtergroup.createfilter('stringfilter', filtervalue, filtercondition);
                // fill the orders depending on the id.
                var ordersbyid = [];
                for (var m = 0; m < orders.length; m++) {
                    var result = filter.evaluate(orders[m]["EmployeeID"]);
                    if (result)
                        ordersbyid.push(orders[m]);
                }
                var orderssource = { datafields: [
                    { name: 'EmployeeID', type: 'string' },
                    { name: 'ShipName', type: 'string' },
                    { name: 'ShipAddress', type: 'string' },
                    { name: 'ShipCity', type: 'string' },
                    { name: 'ShipCountry', type: 'string' },
                    { name: 'ShippedDate', type: 'date' }
                ],
                    id: 'OrderID',
                    localdata: ordersbyid
                }
                if (grid != null) {
                    grid.jqxGrid({ source: orderssource, theme: theme, width: 600, height: 200,
                        columns: [
                          { text: 'Ship Name', datafield: 'ShipName', width: 200 },
                          { text: 'Ship Address', datafield: 'ShipAddress', width: 200 },
                          { text: 'Ship City', datafield: 'ShipCity', width: 150 },
                          { text: 'Ship Country', datafield: 'ShipCountry', width: 150 },
                          { text: 'Shipped Date', datafield: 'ShippedDate', width: 200 }
                       ]
                    });
                    // bind to rowclick of nested grid.
                     grid.on('rowclick', function(event)
                     { 
                      }
                }
            }

Thanks Peter, this helps a lot.
It allows me to do rowclicks off the nested grid, but I have rowclicks on the main grid too.
When I click on the nested grid it is still firing the $(“#main_grid”).on(‘rowclick’, function (event) {
Any thoughts on how to keep the nested_grid clicks from firing the main_grid event?
