In the header html of our website we would like to insert a form, but it is not accessible from experience editor or content editor so I would like to insert it directly into the cshtml page for the header. I feel like it should be relatively simple, but have run into the wall.

I tried the below (but I really don't know what I'm doing) and it did not work.

@Html.Sitecore().Rendering("/sitecore/layout/Renderings/Modules/Web Forms for Marketers/Mvc Form", new {"formId","{11223344-5566-7788-9900-AABBCCDDEEFF}"})

I also tried:


And I tried substituting the path for the id of the form.

Instead of passing FormId try to pass Data Source for the MVC form, like:

@Html.Sitecore().Rendering("{F2CCA16D-7524-4E99-8EE0-78FF6394A3B3}", new { DataSource = "{11223344-5566-7788-9900-AABBCCDDEEFF}" })

Where {F2CCA16D-7524-4E99-8EE0-78FF6394A3B3} is the WFFM MVC Form and {11223344-5566-7788-9900-AABBCCDDEEFF} is the WFFM form as a data source.


You will need to pass Unique Id of the form as below:

@Html.Sitecore().Rendering("{F2CCA16D-7524-4E99-8EE0-78FF6394A3B3}", new { Datasource = "<id of the form item>" , UniqueId = "<unique id of the form rendering>"})

reference: https://doc.sitecore.com/developers/90/web-forms-for-marketers/en/insert-a-web-form-directly-on-a-web-page.html

  • That generated a LOT of error messages. The root cause seemed to be this error: ...Message: uniqueId is empty Parameter name: uniqueId Source: Sitecore.Kernel at Sitecore.Diagnostics.Assert.ArgumentCondition(Boolean condition, String argumentName, String message) at Sitecore.Forms.Mvc.Models.FormModel..ctor(Guid uniqueId) at Sitecore.Forms.Mvc.Models.FormModel..ctor(Guid uniqueId, Item item)...
