Hidden Fields
The Telerik ASP.NET ASP.NET Core Form component provides built-in support for hidden fields. You can use this feature to perform a number of actions such as hiding the ID property.
The following example demonstrates how to configure a Form with two visible and one hidden field (UserID).
@(Html.Kendo().Form<Kendo.Mvc.Examples.Models.Form.UserViewModel>()
.Name("formExample")
.HtmlAttributes(new { action = "Index", method = "POST" })
.Validatable(v =>
{
v.ValidateOnBlur(true);
v.ValidationSummary(vs => vs.Enable(false));
})
.Items(items =>
{
items.AddGroup()
.Label("Sign up form")
.Items(i =>
{
i.Add()
.Field(f => f.UserID)
.Editor(editor => editor.Hidden());
i.Add()
.Field(f => f.UserName)
.Label(l => l.Text("Username:"));
i.Add()
.Field(f => f.Password)
.Label(l => l.Text("Password:"))
.EditorTemplateHandler("setPasswordEditor");
i.Add()
.Field(f => f.Email)
.Label(l => l.Text("Email:"));
});
})
)
To add support for the HiddenInput attribute, use the following implementation:
[HiddenInput]
public int UserID
{
get;
set;
}
@(Html.Kendo().Form<Kendo.Mvc.Examples.Models.Form.UserViewModel>()
.Name("formExample")
.HtmlAttributes(new { action = "Index", method = "POST" })
.Items(items =>
{
items.Add()
.Field(model => model.UserID);
})
)
<kendo-form name="formExample" form-data="@Model" action="Index" method="POST">
<form-items>
<form-item field="UserId">
</form-item>
</form-items>
</kendo-form>
To add a method for enabling the injection of the AntiForgeryToken input in:
@(Html.Kendo().Form<Kendo.Mvc.Examples.Models.Form.UserViewModel>()
.Name("formExample")
.HtmlAttributes(new { action = "Index", method = "POST" })
.Items(items =>
{
items.AddAntiForgeryToken(Html.AntiForgeryToken());
})
)
