I am upgrading an app to 9.10 and have an issue updating code that uses ProductFieldTypeProvider. In the previous version, the code looked as follows;

protected override Control Render(string id, bool enabled, string value, bool hasError, List<Dynamicweb.UI.Elements.Actions.FieldAddOn> addOns)

and it would return an HtmlInputHidden (in my case). In the new version it now looks like this:

protected override void Render(TextWriter writer, string id, bool enabled, string value, bool hasError, string text, string title)

It's now void and takes a TextWriter. Should I render my control into the TextWriter? If so, how is that done?

Thanks

Imar

Hi Imar,

Yes, that's how it's done. Just write your control into the textwriter - and consider using a htmlwriter to write to your textwriter:

public void Render(TextWriter writer)
{
    using (var htmlWriter = new HtmlTextWriter(writer))
    {
        control.RenderControl(htmlWriter);
    }
}

Let me know if you have any other questions.

BR

Martin
