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.

    Will this error be solved in Infragistics 13.1?

    I still get the error sometimes. For example:

    I delete a row in my grid -> Working great, all fine

    I add a row in the grid -> Still fine, row is added etc.

    I add another row to the grid -> The row is added succesfully, but then the error above occurs.

    It's no problem if I add a few rows without deleting one first. I can't imagine I am doing something wrong...
