Sitecore Forms - Possibility of reading MVC FORM Rendering parameter in Custom Submit Action

Question

I have one Sitecore Form to be used across multiple sites for which I want to configure respective thankyou pages (route might be different for individual site) at rendering parameter. So Is there a possibility of reading Mvc Form Rendering parameter value in Custom Submit Action method or any alternative to achieve ?

Because in Custom Submit Action while reading rendering parameter is always Null. RenderingContext.Current.Rendering.Parameters["RedirectUrl"]

Thankyou.

The possible case can be creating a custom field. You can create a custom field that will be a copy of a hidden field and here you can get the rendering parameters and assign it to the hidden field.

So your view will be something like this.

@using System.Web.Mvc.Html
@model Site.Feature.Forms.Forms.Controls.HiddenField.HiddenFieldModel

{
  var parms = renderingContext.Rendering.Parameters;
  var renderingParamValue = parms["name of the field here"];
}

<input type="hidden" id="@Html.IdFor(m => Model.Value)" name="@Html.NameFor(m => Model.Value)" value="@renderingParamValue" />

In this way you can assign the rendering parameter value to the hidden field and you will get it to your custom submit action.

Hope this helps.
