Responsive Panel gets affected by TemplateInfo.HtmlFieldPrefix

[eyupyusein]

To reproduce the issue, open the following REPL sample:
https://netcorerepl.telerik.com/QyFPmlFR39pKo7vQ51

When this setting is present:

@{
    ViewData.TemplateInfo.HtmlFieldPrefix = "message";
}

The responsive panel's id and name attributes are wrongly affected:

The result should be the the same as if the setting was removed:

This unexpected prefix breaks the layout and other custom logic on the page.

The observed behavior is expected. The framework's DefaultHtmlGenerator.cs relies on the GetFullHtmlfieldName to generate the correct full name for a helper. In a similar approach, the Telerik Helpers rely on the use of the same method when generating the correct full name and id for the components, when an HtmlFieldPrefix is available. Such scenarios include using components in editor templates or in partial views, for example.

The particular report concerns the issue that the selector is changed and custom styling cannot be applied. The scenario can be handled using a CSS Wildcart Selector to target elements regardless of their full name. The condition "ends with" can be used for the scenario in question:

[id$="slidebarl"] {
    // apply styling
}
