Rendering Forms

There are three options available for rendering a form.

Rendering Using a View Component

To display a form in your view, you can make a call to a view component:

@await Component.InvokeAsync("RenderForm", new { formId = Guid.Parse("<form guid>"), theme = "default", includeScripts = false })

Four parameters can be provided:

• formId is the GUID of a form.

• theme is the name of a theme. If not provided, the default theme is used (see Themes).

• includeScripts indicates whether scripts should be rendered with the form (see Rendering Scripts.

• recordId is an optional existing record GUID, used if editing records via the website is enabled in configuration

Usually, rather than hard-coding the form's GUID, you'll use a form and/or theme picker property on your page:

@await Component.InvokeAsync("RenderForm", new { formId = @Model.Form, theme = @Model.Theme, includeScripts = false })

Rendering Using a Tag Helper

If you prefer a tag helper syntax, you can use one that ships with Umbraco Forms.

Firstly, in your _ViewImports.cshtml file, add a reference to the Umbraco Forms tag helpers with:

@addTagHelper *, Umbraco.Forms.Web

Then in your view you can use:

@if (Model.Form.HasValue)
{
    <umb-forms-render form-id="@Model.FormId.Value" theme="@Model.FormTheme" exclude-scripts="true" />
}

Rendering Using a Macro

With a grid or Rich Text Editor, you need to use a macro. This is also available as an option to display a form in your view, where you provide three parameters:

@await Umbraco.RenderMacroAsync("renderUmbracoForm", new { FormGuid = "<form guid>", FormTheme = "default", ExcludeScripts = "1" })

• FormGuid is the GUID of a form.

• FormTheme is the name of a theme. If not provided, the default theme is used.

• ExcludeScripts takes a value of 0 or 1, indicating whether scripts should be excluded from rendering.

Similarly, you can reference a form picker property on your page:

@if (Model.FormId is Guid formId)
{
    @await Umbraco.RenderMacroAsync("renderUmbracoForm", new { FormGuid = formId, FormTheme = Model.FormTheme, ExcludeScripts = "1" })
}
