ASP.NET Core Form Overview

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

The Telerik UI Form for ASP.NET Core allows you to generate and manage forms. Through a variety of configuration options, it makes creating and customizing forms a seamless experience. Achieve the desired form appearance by using default or custom editors, choose layout and orientation, display the editors in groups and columns, and configure validation.

Initializing the Form

The following example demonstrates how to define the Form.

Razor

        @(Html.Kendo().Form<MyApplication.Models.UserViewModel>()
        .Name("form")
        .HtmlAttributes(new { action = "Index", method = "POST" })
        .Validatable(v =>
        {
            v.ValidateOnBlur(true);
            v.ValidationSummary(vs => vs.Enable(true));
        })
        .Items(items =>
        {
            items.AddGroup()
                .Label("Registration Form")
                .Items(i =>
                {
                    i.Add()
                        .Field(f => f.FirstName)
                        .Label(l => l.Text("First Name:"));
                    i.Add()
                        .Field(f => f.LastName)
                        .Label(l => l.Text("Last Name:"));
