The PropertyGrid is part of Telerik UI for ASP.NET Core, a professional grade UI library with 110+ components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.

The Telerik UI PropertyGrid TagHelper and HtmlHelper for ASP.NET Core are server-side wrappers for the Kendo UI PropertyGrid widget.

The PropertyGrid allows you to display and edit properties and attributes of objects. You can bind the component to a Model, edit its nested properties, specify the desired editor and customized template, group, sort, search, or navigate through the data or export it in Excel and PDF.

Initializing the PropertyGrid

The following example demonstrates how to define the PropertyGrid.

    @model PropertyViewModel

    @(Html.Kendo().PropertyGrid<PropertyViewModel>()
        .Name("propertyGrid")
        .Model(Model)
        .Columns(columns => 
        {
            columns.FieldColumn(fieldCol => fieldCol.Width(200));
            columns.ValueColumn(valueCol => valueCol.Width(250));
        })
    )
    @addTagHelper *, Kendo.Mvc
    @model PropertyViewModel

    <kendo-propertygrid name="propertyGrid" model="@Model">
        <columns>
            <field-column width="200" />
            <value-column width="250" />
        </columns>
    </kendo-propertygrid>
    using System.ComponentModel.DataAnnotations;

    public class PropertyViewModel
    {
        [Display(GroupName = "Size", Description = "Control the width of the element.")]
        public int Width { get; set; }

        [Display(GroupName = "Size", Description = "Control the height of the element.")]
        public int Height { get; set; }

        [Display(GroupName = "Alignment", Description = "Add space around the element.")]
        public int Margin { get; set; }

        [Display(GroupName = "Alignment", Description = "Add space around the content of the element.")]
        public int Padding { get; set; }
    }
    public ActionResult Index()
    {
        return View(new PropertyViewModel()
        {
            Width = 500,
            Height = 300,
            Margin = 20,
            Padding = 50
        });
    }

Basic Configuration

The PropertyGrid provides a variety of options for the items configuration, toolbar, context menu, and appearance options like width, height, resizability, and more. The following example demonstrates the basic configuration of the PropertyGrid.

    @model PropertyViewModel

    @(Html.Kendo().PropertyGrid<PropertyViewModel>()
        .Name("propertyGrid")
        .Model(Model)
        .EditMode(true)
        .ContextMenu(true)
        .Columns(columns => 
        {
            columns.FieldColumn(fieldCol => fieldCol.Width(200));
            columns.ValueColumn(valueCol => valueCol.Width(250));
        })
        .Items(items =>
        {

            items.Add().Field(f => f.Width)
                .Editor(editor => editor.NumericTextBox().Step(1).Min(1).Max(1000));
            items.Add().Field(f => f.Height)
                .Editor(editor => editor.NumericTextBox().Step(1).Min(1).Max(1000));
            items.Add().Field(f => f.Icon)
                .Editor(editor => editor
                    .DropDownList()
                    .DataTextField("Text")
                    .DataValueField("Value")
                    .BindTo(new List<SelectListItem>() {
                        new SelectListItem() {
                            Text = "search", Value = "search"
                        },
                        new SelectListItem() {
                            Text = "user", Value = "user"
                        },
                        new SelectListItem() {
                            Text = "folder", Value = "folder"
                        }
                    }));
        })
    )
    @addTagHelper *, Kendo.Mvc
    @model PropertyViewModel

    @{
        var icons = new List<SelectListItem>() {
            new SelectListItem() {
                Text = "search", Value = "search"
            },
            new SelectListItem() {
                Text = "user", Value = "user"
            },
            new SelectListItem() {
                Text = "folder", Value = "folder"
            }
        };
    }

    <kendo-propertygrid name="propertyGrid" model="@Model" edit-mode="true">

    using System.ComponentModel.DataAnnotations;

    public class PropertyViewModel
    {

        return View(new PropertyViewModel()
        {
            Width = 500,
            Height = 300,
