Multi-Column Headers

The multicolumn headers of the Grid represent a tree-like structure where the user can group one or more columns together by a common header.

For a runnable example, refer to the demo on implementing multi-column headers in the Grid.

That common header in turn can be a child of another upper MultiColumn header which can also span both columns and other headers.

    .Columns(columns =>
        columns.Group(colGroup =>
            colGroup.Title("Ship Information");
            colGroup.Columns(cols =>
                cols.Bound(f => f.OrderID).Width(200);
                cols.Bound(f => f.ShipCountry).Width(200);

The previous example results in the following output.

UI for ASP.NET MVC Grid with a column group

A full Grid with Multi-column headers would look like below

    .Columns(columns =>
        columns.Bound(c => c.CompanyName).Width(420);
        columns.Group(group => group
            .Title("Contact Info")
            .Columns(info => {
                info.Bound(x => x.ContactTitle).Width(200);
                info.Bound(x => x.ContactName).Width(200);
                info.Group(g => g.Title("Location")
                    .Columns(location =>
                        location.Bound(c => c.Country).Width(200);
                        location.Bound(c => c.City).Width(200);
                info.Bound(x => x.Phone);
    .Resizable(resizable => resizable.Columns(true))
    .Reorderable(reorderable => reorderable.Columns(true))
    .HtmlAttributes(new { style = "height: 550px;" })
    .DataSource(dataSource => dataSource
        .Read(read => read.Action("MultiColumn_Customers_Read", "Grid"))
