Question

How can I write this in javascript instead of using the MVC Wrapper?

@(Html.Kendo().Grid(Model.List)
      .Name("grid")
    .Columns(c => { 
        c.Bound(e => e.ID); 
        c.Bound(e => e.Nom).HeaderHtmlAttributes(new { colspan = 2 }); 
        c.Bound(e => e.Nb).HeaderHtmlAttributes(new { style= "display:none;" }); 
    })
)

I started with the following code to experiment, I know it is not an exact
match to the attributes mentioned above, but how can I set
HeaderHtmlAttributes and Headertemplate for columns with javascript for the Kendo grid?

$("div#kendogrid").kendoGrid({
        dataSource: dataSource,
        columns: [
             {
                 field: "ID",
                 title: "Nr Id",
                 headerTemplate: "sample template text col 1",
                 width: 100
             },
             {
                 field: "Nom",
                 headerAttributes: {
                     "class": "myHeader",
                     style: "text-align: right"
                 },
                 width: 200
             }
        ]
    });

You are correct, HeaderHtmlAttributes is specified using columns.headerAttributes and the equivalent to your HeaderTemplate is columns.headerTemplate. See the links for documentation:

• http://docs.kendoui.com/api/web/grid#columnsheaderattributes-object
• http://docs.kendoui.com/api/web/grid#columnsheadertemplate-string

The translation of your original code would be:

$("#kendogrid").kendoGrid({
    dataSource: dataSource,
    columns   : [
        {
            field: "ID"
        },
        {
            field           : "Nom",
            headerAttributes: {
                colspan: 2
            }
        },
        {
            field           : "Nb",
            headerAttributes: {
                style: "display:none"
            }
        }
    ]
});
