Description

How can I render icons for a Boolean column in the Telerik UI for ASP.NET MVC Grid?

Solution

To achieve the desired scenario:

  1. Specify a column template for the Boolean column by using the ClientTemplate() configuration method and provide a function handler.
  2. Within the handler, replace the default true and false values by using the conventional Kendo UI Web Font Icons.
    @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
        .Name("Grid")
        .Columns(columns => {
            columns.Bound(p => p.ProductName);
            columns.Bound(p => p.UnitPrice).Width(140);
            columns.Bound(p => p.UnitsInStock).Width(140);
            columns.Bound(p => p.Discontinued).ClientTemplate("#=discTemplate(data)#").Width(100); // Use the template syntax to invoke the function whilst passing the data object of the current model.
            columns.Command(command => command.Destroy()).Width(150);
        })
        .ToolBar(toolbar => {
            toolbar.Create();
            toolbar.Save();
        })
        .Editable(editable => editable.Mode(GridEditMode.InCell))
        .Pageable()
        .Navigatable()
        .Sortable()
        .Scrollable()
        .DataSource(dataSource => dataSource
            .Ajax()
            .Batch(true)
            .PageSize(20)
            .ServerOperation(false)
            .Model(model => model.Id(p => p.ProductID))
            .Create("Editing_Create", "Grid")
            .Read("Editing_Read", "Grid")
            .Update("Editing_Update", "Grid")
            .Destroy("Editing_Destroy", "Grid")
        )
    )
    <script type="text/javascript">
       function discTemplate(data) { // Render an icon based on a ternary operator evaluation.
             return data.Discontinued ? "<span class='k-icon k-i-check'></span>" : "<span class='k-icon k-i-x'></span>"
       }
    </script>
