Currently, the grid select method operates on the whole page which can easily be an issue if there is more than one HTML table.

Eg: $('#myGrid').data('kendoGrid').select('tr') should only select all rows but actually applies the 'k-state-selected' class to all <tr> elements on the page.

In cases such as $('#myGrid').data('kendoGrid').select('tr:eq(0)') may not select a row in your grid at all since it selects the first row anywhere on the.

Since I've already specified my grid by ID, I would expect the chain of functions to respect that.

Two possible workarounds are:
1. 
$('#myGrid').data('kendoGrid').select('#myGrid tr').
2. 
var grid = $("#myGrid").data("kendoGrid");
var row = grid.tbody.find("tr:eq(0)");
grid.select(row);
