    my requirement is to have a custom button on each data row.

    When a user clicks the button the detail row expands for that specific row only.

    I am able to expand and collapse using the button, but its doing it for the entire grid. 

    What do i need to do to keep it to the current(selected) row.

    command.Custom("View Classes").Click("showClasses");

    function showClasses(e)


        var grid = $("#Grid").data("kendoGrid");

          if ("tr.k-state-selected")

                   var $link = grid.tbody.find("td.k-hierarchy-cell .k-icon");

    Hi Michael,

    Your current selector gets all of the expand/collapse icons and simulates click to all of them. Instead, you will need to call this only for the corresponding row element:
    function showClasses(args) {
        var row = $(args.target).parents("tr").first();
        var icon = row.find(".k-hierarchy-cell>a.k-icon");

    If you will remove the built-in button column, you can also achieve this requirement using the expandRow and collapseRow methods accordingly:

    I hope this will prove helpful.
