How to add a css class to the last row in jsGrid - css

Question

I want to add some styling to the last row in my grid. I wont know what the row number is as there could be any number of rows. How can I go about this? I've seen rowClass and rowRenderer but not a working example. Here is the code I have:
var displayData = function (itemViewModelList) {
var fields = [
{
name: 'ConsultantName', type: 'text', width: 100, title: 'Consultant Name'
},
{
name: 'BranchName', type: 'text', width: 100, title: 'Branch Name', css: "red"
},
{ name: 'NumberOfInvestments', type: 'text', title: 'Number Of Investments' },
{
name: 'ValueOfInvestments', type: 'money', width: 150, title: 'Value Of Investments',
itemTemplate: function (value) {
return tisCommon.formatForMoney(value);
}
},
{
name: 'AverageValueOfInvestments', type: 'money', width: 150, title: 'Average Value Of Investments',
itemTemplate: function (value) {
return tisCommon.formatForMoney(value);
}
},
{
name: 'Month', type: 'text', width: 100, title: 'Month',
itemTemplate: function (value) {
return moment(value, 'M').format('MMMM');;
}
},
];
var options = {
inserting: false,
editing: false,
pageSize: 20,
fields: fields,
rowHeaders: false,
colHeaders: false,
data: itemViewModelList,
controller: controller = {
loadData: function () {
},
},
};
$('#investment-grid').tisGrid('', options);
if (itemViewModelList[0].ConsultantName != null) {
$("#investment-grid").jsGrid("fieldOption", "BranchName", "visible", false);
} else {
$("#investment-grid").jsGrid("fieldOption", "ConsultantName", "visible", false);
}
};
My data being passed "itemViewModelList" is an array of objects

Answer 1

I resolved this by using rowClass as follows:
controller: controller =
{
loadData: function () {},
},
rowClass: function (item, itemIndex) //item is the data in a row, index is the row number.
{
if ((item.ConsultantName == "Totals") || (item.BranchName == "Totals"))
{
return "totalItem highlight";
}
}
I have my if statement where I find the item in the last row based on my conditions. When they are met, I add my custom CSS classes to that row.
