Updating igGrid with JSON data
posted

Hi,

I am trying to reload the data in my Infragistics grid using a knockout datasource. I have got the following code:

    MYNAMESPACE.gridFunctions.prototype.refresh = function (data) {
        
        if (data == undefined) {
            $(".ajax-loader").css("display", "block");
            MYNAMESPACE.gridFunctions.prototype.read(undefined, MYNAMESPACE.gridFunctions.prototype.refresh)
            return;
        }
        MYNAMESPACE.viewModel.books = ko.mapping.fromJS($.parseJSON(data));
        ko.applyBindings(MYNAMESPACE.viewModel);
        $(".ajax-loader").css("display", "none");
    };

"MYNAMESPACE.gridFunctions.prototype.read" is a REST/AJAX function which gets JSON data from the server.

When testing the functionality it seems to work, but the second refresh I get the following error:

TypeError: g[(w + d.owner._startRowIndex)] is undefined
...ngth-1][d.options.primaryKey])}}else{if(f().length>h.length){k=f()[f().length-1]...

I have no idea what might be wrong.. anyone?

Thanks in advance.
