Hello Diwakar,

I believe you are looking for the remote data loading scenario. If you want to handle clicks on the entire row, you can call the expandRow method via a jQuery event handler on the .k-grid-content tr elements:

$("body").on("click", ".k-grid-content tr", function(e) {
    var row = $(e.target).closest("tr");
    var treelist = row.closest(kendo.roleSelector("treelist")).data("kendoTreeList");
    if (treelist && row.length) {
        treelist.expand(row);
    }
});
