How to set MaxLength of input in child grid (.net core)?

[SK]

Hello, I am looking to limit the length of "Comment" to 1000 characters. Adding custom style via HtmlAttributes does not apply it to the input attributes and I am unsure how. Any insight would be great. 

                                    @(Html.Kendo().Grid<SomeUI.Areas.Models.SomeCommentsModel>()
                                     .Name("SomeCommentsGrid_#=PONum#_#=lineNum#") 
                                      .Columns(columns =>
                                      {
                                          columns.Bound(p => p.comment).Title("Comment").Width(100);
                                          columns.Bound(p => p.updatedBy).Title("Updated By").Width(15).Editable("readOnlyCol");
                                          columns.Bound(p => p.lastUpdated).Title("Last Updated").Width(25).Format("{0:MM/dd/yyyy}").Editable("readOnlyCol");
                                      })
                                      .ToolBar(toolbar => {
                                          toolbar.Create();
                                          
                                      })
                                      .Editable(editable => editable.Mode(GridEditMode.InCell))
                                      .Selectable(selectable => selectable
                                        .Mode(GridSelectionMode.Single))
                                      .Events(ev => ev.Change("onChange"))
                                      .DataSource(dataSource => dataSource
                                        .Ajax()
                                        .Read(read => read.Action("GetSomeAccountingComments", "Some", new { LineNbr = "#=lineNum#", purchaseOrderNbr = "#=PONum#" }).Data("GetFacilityCode"))
                                        .Sort(sort => sort.Add("lastUpdated").Descending())
                                        .PageSize(10)
                                        )
                                        .Sortable()
                                        .Pageable()
                                        .Width(1000)
                                        .ToClientTemplate())

Have you tried setting the [StringLength] annotation on the property in your model? 

        [StringLength(1000)]
        public string Comments { get; set; }

That worked. I had only tried MaxLength but not StringLength. Thanks.
