Execution time of tag extensions

Hi,

Just discovered how to write custom tagextensions (with Razor fallback) and was very happy, however I discover that it does not work on custom tags.

Why is that?

Can you provide an example?

Not a concrete example. Imagine that a custom tag exists, say: firstweb:Hello.Price

I want to do some solution related post parsing of say prices, something which should apply to some prices (not all) shown on the website.

Imagine a "pretty" price, like "19995,00" should be shown as "19.995,-" and we build a tag extension "PrettyPrice()".

The custom tag would then be extended the tag extension: firstweb:Hello.Price.PrettyPrice()

The price from that tag will not become a pretty price, but a standard Dynamicweb eCom tag will become a pretty price.

This works for me on Dynamicweb 8.4.1:

using Dynamicweb;
using Dynamicweb.eCommerce.Products;
using Dynamicweb.Rendering;
using Dynamicweb.Extensibility;

namespace TemplateExtenders
{
    public class CustomTemplateExtender : ProductTemplateExtender
    {
        public override void ExtendTemplate(Dynamicweb.Rendering.Template template)
        {
            template.SetTag("custom:tag", 1.23);
        }
    }

    [AddInName("debug")]
    public class TagExtensionMethodTest : TagExtensionMethod
    {
        public override string ExecuteMethod(string value)
        {
            // @TODO Do something with value
            return System.Net.WebUtility.HtmlEncode(Newtonsoft.Json.JsonConvert.SerializeObject(new
            {
                value = value,
                self = this
            }));
        }
    }
}

Use in template:

<pre>@custom:tag: <!--@custom:tag-->
@custom:tag.debug(): <!--@custom:tag.debug()-->
@custom:tag.debug(a, b, c): <!--@custom:tag.debug(a, b, c)-->
</pre>

Best regards,

Hi Mikkel,

Great - thank you. We are on this customer coding on an older DW version (Dynamicweb.dll 8.3.1.11) so I guess it makes sense, so I hope!
