I am building a Kendo grid. I would like to hide the destroy (delete) mand in the grid on page load. After that, when I click a button on the page, it should be visible.

Kendo grid:

@(Html.Kendo().Grid<Model>() 
    .Name("grid")
    .Columns(columns =>
    {
        columns.Bound(product => product.DESCRIPTION).Title("Description");
        columns.Bound(product => product.CODE).Title("Description");
        columns.Command(mands =>
        {
            mands.Destroy().HtmlAttributes(new { id = "buttondelete" }); 
        }).Title("Operations");
    })
    .ToolBar(toolbar =>
    {
        toolbar.Create().Text("Add Records"); 
        toolbar.Save(); 
    })
                                 
    .Editable(editable => editable.Mode(GridEditMode.InCell)) 
    .Pageable(pager => pager
        .PageSizes(true)
        .Input(true)
        .Refresh(true)
    )
    .DataSource(dataSource => dataSource
        .Ajax()
        .ServerOperation(true)
        .Events(events => events.Error("onError"))
        .Model(model =>
        {
            model.Id(product => product.ID); // Specify the property which is the unique identifier of the model
            model.Field(p => p.DESCRIPTION).Editable(false);
            model.Field(product => product.CODE).Editable(false);
        })
        .Create(create => create.Action("a", "www")) 
        .Read(read => read.Action("b", "www"))  
        .Update(update => update.Action("c", "www"))  
        .Destroy(destroy => destroy.Action("d", "www")) 
    )
)

JS:

<script type="text/javascript">

    $(document).ready(function () {
        //$("#grid").find(".k-grid-delete").hide() // hide delete button
        $("#grid").find(".k-toolbar").hide(); // hide toolbar
        $(".k-grid-delete", "#grid").hide();
    });
    
    $('#EnableEdit').click(function () {
        $("#grid").find(".k-toolbar").show();
        
        // $(".k-grid-delete", "#grid").show();
        var grid = $("#grid").data("kendoGrid");
        grid.dataSource.at(0).fields["CODE"].editable = true;
        grid.dataSource.at(0).fields["DESCRIPTION"].editable = true;
    });

</script>

Edit: changed some parts according to first answer. Now $(".k-grid-delete", "#grid").hide(); cannot hide k.grid-delete class. I guess JavaScript is loaded before the kendo grid is created. When I use it inside the click function of the edit button, it hides the delete buttons.

If you use the same id for each columns you have many elements with the same id which is not legal. Try using the CSS class attribute that identifies a delete button and on creation (page load) hide it and then on click show it.

Code for hiding them

$(".k-grid-delete", "#grid").hide();

Code for showing them back

$('#EnableEdit').click(function () {
    $(".k-grid-delete", "#grid").show();
});

For change kendo-grid setting, you must re-create your grid. You can ment out "for offlide data", if you gird binding to remote data.

setGridReadOnly: function (gridId, isReadOnly) {

    var grid;

    grid = $("#" + gridId).data("kendoGrid");

    var myOpt = grid.options;
    myOpt.editable.create = !isReadOnly;
    myOpt.editable.destroy = !isReadOnly;
    myOpt.editable.update = !isReadOnly;
    if (isReadOnly == true)
        myOpt.editable.mode = "null";
    else
        myOpt.editable.mode = "inline";

    //for offlide data.
    var data = grid._data;
    //

    grid.destroy();

    $("#" + gridId).kendoGrid(myOpt).data("kendoGrid");

    //for offlide data.
    $("#" + gridId).data("kendoGrid").dataSource.data(data);
    //

    if (isReadOnly == true) {
        $("#" + gridId).find(".k-grid-delete").hide();
        $("#" + gridId).find(".k-grid-edit").hide();
        $("#" + gridId).find(".k-grid-add").hide();
    } else {
        $("#" + gridId).find(".k-grid-delete").show();
        $("#" + gridId).find(".k-grid-edit").show();
        $("#" + gridId).find(".k-grid-add").show();
    }

}
