Kendo grid for ASP.NET MVC Examples

In this article we will cover some common business scenarios that we frequently encounter when using Kendo Grid for MVC.

First of all, grab the ASP.NET MVC Kendo trial installer from the link below:

Now once you are done with installation, please go through the following link so we have all setup to try code that we go through in next section and ready to hit F5!

Dynamic columns
Once I had a scenario to dynamically display search query result set based on the result set I received. The result is of type dynamic and could have various columns based on the keyword searched. I come up with following model to satisfy the need of handling dynamic columns.

public class SearchResult {
    public DataTable ResultData { get; set; }
    public Dictionary<string, Type> ColumnsBind { get; set; }

Listing 1.0 SearchResult class

To populate search results, we will use following mock method which adds some sample data and it will return object of class as per Listing 1.0.

public ActionResult SearchResults(string keyWord)
            var result = new SearchResult();
            result.ResultData = this.GetTable();
            var colls = new Dictionary<string, System.Type>();
            foreach (System.Data.DataColumn column in result.ResultData.Columns)
                var t = System.Type.GetType(column.DataType.FullName);
                 colls.Add(column.ColumnName, t);

            result.ColumnsBind = colls;

             return this.View("SearchResults", result);

private DataTable GetTable()
            var table = new DataTable("Result");
            Random rnd = new Random();
            var val = rnd.Next(3, 8);
             for (int i = 0; i < val; i++)
                 table.Columns.Add("Column_" + i, typeof(string));

             for (int i = 0; i < 10; i++)
                var row = table.NewRow();

                 for (int j = 0; j < val; j++)
                      row["Column_" + j] = "field_" + j;


            return table;

Listing 1.1 Action method and methods for mock data

We are going to use Razor view here named SearchResults. The code to use Kendo grid is as following:

    .Name( "SearchResultGrid" )
    .Columns( columns => {
         //Define the columns from
        foreach ( var c in Model. ColumnsBind)
            columns.Bound( c.Value, c.Key );
    } )
    .DataSource( model => model. ResultData)

Listing 1.2 Kendo Grid definition

Now once you run it, it should show you result in nice Kendo grid!

Column title from attribute
Often you need to display different title for your data grid column than the property name. One way of doing so is doing it in JS as following:

columns.Bound(model => model.Identity).Title("User ID");

The other way around is to do it on server side by implementing AssociatedMetadataProvider. This way, you can control column names from server side and saves your effort to maintain them in view/JS for all the occurrences of the column.
Consider the class shown in Listing 1.3 below.

public class Employee
         public string Identity { get; set; }
        public string Address1 { get; set; }
        [Display("Street address")]
        public string Address2 { get; set; }

Listing 1.3 Employee class

In the custom metadata provider that we will develop just now, we want to give custom title for Address related properties when they do not have Display attribute set. So implementation of our custom metadata provider will be something like following as per Listing 1.4

public class AddressMetadataProvider : AssociatedMetadataProvider
        public AddressMetadataProvider()
            : base()

         protected override ModelMetadata CreateMetadata(IEnumerable<Attribute> attributes, Type containerType, Func<object> modelAccessor, Type modelType,
                                                        string propertyName)
            var metaData = new ModelMetadata(this, containerType, modelAccessor, modelType, propertyName);

             if (propertyName == null)
                 return metaData;
             if (propertyName.StartsWith("Address") && attributes == null)
                metaData.DisplayName = "Address line";
                 if (attributes != null)
                    foreach (var a in attributes)
                        var type = a.TypeId as Type;
                         if (type != null && type.Name == "DisplayAttribute")
                            var displayName = (a as DisplayAttribute).Name;
                              if (!string.IsNullOrEmpty(displayName))
                                metaData.DisplayName = displayName;


             return metaData;

Listing 1.4 AddressMetadataProvider class

One more step is required to tell MVC framework to look for metadata using this provider. To do so, register it in global.asax.cs as following:

protected void Application_Start()
ModelMetadataProviders.Current = new AddressMetadataProvider();

Listing 1.5 Register AddressMetadataProvider

Conditional client template
It is quite common to display different value or control altogether based on the property values. For example, based on the user access level, you may want to present him with various command buttons such as Process button. We can use Kendo grid client template with set of conditions to do so. Code listing 1.6 shows that


.Columns(columns =>
  columns.Bound(o => o.AccountManager).Title("Admin").ClientTemplate("# if (IsAdmin) { #" + @Html.ActionLink("Process", "ProcessRequest", "AdminController") + "# }else {#" + "No admin access" + "#} #");  

Listing 1.6 Conditional client template

Radio button list from Enum
For your enum properties, sometimes you need a view where you present user with all the enum values and allow single selection out of it. In such cases, developing up EditorTemplate for the given type is the way to go. Here I will show you code for developing one for Enum.

@model Enum
    // Looks for Display attribute on property
    Func<Enum, string> GetDescription = enumField =>
       Type type = en.GetType();
        System.Reflection.MemberInfo[] memInfo = type.GetMember(en.ToString());

         if (memInfo != null && memInfo.Length > 0)

            object[] attrs = memInfo[0].GetCustomAttributes(typeof(System.ComponentModel.DataAnnotations.DisplayAttribute),

             if (attrs != null && attrs.Length > 0)
                 return ((System.ComponentModel.DataAnnotations.DisplayAttribute)attrs[0]).GetName();

         return enumField.ToString();
    var listItems = Enum.GetValues(Model.GetType()).OfType<Enum>().Select(e =>
    new SelectListItem()
        Text = GetDescription(e),
        Value = e.ToString(),
        Selected = e.Equals(Model)
    string prefix = ViewData.TemplateInfo.HtmlFieldPrefix;
    int index = 0;
    ViewData.TemplateInfo.HtmlFieldPrefix = string.Empty;

    foreach (var li in listItems)
        string fieldName = string.Format(System.Globalization.CultureInfo.InvariantCulture, "{0}_{1}", prefix, li.Value);
            @Html.RadioButton(prefix, li.Value, li.Selected, new { @id = fieldName })
            @Html.Label(fieldName, li.Text)
    ViewData.TemplateInfo.HtmlFieldPrefix = prefix;

Listing 1.7 EnumRadioButtonList EditorTemplate

The usage is quite simple.

@Html.EditorFor(model => model.EmployeeType, "EnumRadioButtonList")
