The POC continues. As you may have noticed the solution I wrote about yesterday only worked sever side, no client side validation e.g.
This can be fixed as well. First I added another method to my util class, to get the fake ControllerContext and refactored it, so you won’t need the Dummy controller. I just use the FormContainerController: You will need that later.
public static ControllerContext GetFormControllerContext()
{
try
{
HttpContextBase httpContextBase = new HttpContextWrapper(HttpContext.Current);
RouteData routeData = new RouteData();
routeData.Values.Add("controller", "FormContainerBlock");
routeData.Values.Add("action", "Index");
return new ControllerContext(new RequestContext(httpContextBase, routeData), new FormContainerBlockController());
}
catch (ArgumentNullException argumentNullException)
{
Log.Critical("Cannot create controllercontext for the FormContainerBlock: \r\n {0}", argumentNullException);
}
return null;
}
Next I added the method from the controller to register the resources to my UserControl, the complete code is in Gist:
public partial class FormContainerBlockControl : BlockControlBase<FormContainerBlock>
{
protected ContentArea FakeArea { get; private set; }
protected ControllerContext FakeContext { get; private set; }
protected void Page_Load(object sender, EventArgs e)
{
this.FakeContext = MvcUtility.GetFormControllerContext();
this.SetResources(this.FakeContext);
// this.Page.Form.ID = this.CurrentBlock.Form.FormGuid.ToString();
if (!PageEditing.PageIsInEditMode)
{
GhostForm form = this.Page.Form as GhostForm;
if (form != null)
{
form.RenderFormTag = false;
}
}
ContentArea contentArea = new ContentArea();
contentArea.Items.Add(new ContentAreaItem { ContentLink = this.CurrentBlock.Content.ContentLink });
this.FakeArea = contentArea;
this.DataBind();
}
protected void Page_PreRender(object sender, EventArgs e)
{
this.SetVisitorIdentifierIfNeeded(this.FakeContext.HttpContext);
}
}
Still no luck though. Because you are using WebForms you have two forms, which confuses the module. So I somethingto hide the WebForms form when there is an EPiServer form on the page. I hope the Forms team will add an option to disable rendering the form tag. That way you can just set some attributes, instead of hiding it. So a custom control. You will need to replace the form control on your page with this custom one, thanks Jeremy
public class GhostForm : HtmlForm
{
protected bool render;
public bool RenderFormTag
{
get { return this.render; }
set { this.render = value; }
}
public GhostForm()
{
//By default, show the form tag
this.render = true;
}
protected override void RenderBeginTag(HtmlTextWriter writer)
{
//Only render the tag when render is set to true
if (this.render)
{
base.RenderBeginTag(writer);
}
}
protected override void RenderEndTag(HtmlTextWriter writer)
{
//Only render the tag when render is set to true
if (this.render)
{
base.RenderEndTag(writer);
}
}
}
You see in the UserControl that I hide the WebForm when the control is on a page.
After this hack clientside validation was working, the default css was there. Yay. And the forms were submitted and the data could be retrieved.
This feels more hackish than what I did yesterday. So I’ll ask the forms team if they would be willing to make the rendering of the EPiServer Forms tag optional/disable it with a setting. That way you could do something like this in your masterpage:
<form runat="server" enctype="multipart/form-data" class="EPiServerForms " data-epiforms-type="form" ClientIDMode="Static">
And in the UserControl
this.Page.Form.ID = this.CurrentBlock.Form.FormGuid.ToString();
I will also ask them to make the setting of the resources that is done in the controller a separate method we can use.
So another step further and more testing to do.
All updated code en new code is on gist.
I have put all code on GitHub, you can also download a zip with the compiled dll and the views.
The POC continues in pt3

Hi, does this saves file upload submissions?

When I created it, it did. But remember… It is a “hack”, there are no guarantees it will keep working
