Question regarding asp.net webforms > .ascx

[VincentVanHulstPersonal]

Hello, i was wondering if it would be possible to also minify the content of the html output rendered through .ascx controls? I have some .aspx pages with placeholders that load .ascx files on page init. The output of the .aspx page is minified/compressed but not the contents of the .ascx files.

Hello, Vincent!

Quite non-standard functionality, similar to a CMS. I definitely haven't tested such things.

There are two ways to solve this problem:

1. Use the WebMarkupMin.AspNet4.HttpModules module instead of the WebMarkupMin.AspNet4.WebForms module.
2. Try to reproduce this error in the form of demo project and send me a link to it. Then I'll see how I can fix this problem.

HTML output of the following code is completely minified:

protected void Page_Init(object sender, EventArgs e)
{
    var myControl = this.LoadControl("~/Controls/MyControl.ascx") as MyControl;
    myPlaceholder.Controls.Add(myControl);
}

Thank you for this feedback. I will dive into this again. Only other thing that i can think of is that we have some nested .ascx loading. (index.aspx > main.ascx > overview.ascx).

Furthermore I have index.aspx > Inherits WebMarkupMin.AspNet4.WebForms.MinifiedAndCompressedHtmlPage The .ascx's just inherit > System.Web.UI.UserControl Is that correct?

[Taritsyn]

Yes, this is correct.

Does the .ascx file contain the pre and textarea tags, or ignoring comment tags?

[VincentVanHulstPersonal]

Ok i think for now we can close this issue; i now see some html parsing errors in de logger. Probably that is the issue. Regarding your question: we do have textarea tags.

[VincentVanHulstPersonal]

Yes problem solved; i found invalid markup in some CMS-content. Thank you for your help.

Content of tags listed above is never minified.

I recommend you to write your own logger or use the built-in logger (ThrowExceptionLogger class). If you use ASP.NET Web Forms, then the logger for WebMarkupMin needs to be registered in the App_Start/WebMarkupMinConfig.cs file as follows:

using WebMarkupMin.Core.Loggers;
…
DefaultLogger.Current = new ThrowExceptionLogger();
