### Bug report

When setting the NoDataTemplate() option to an empty string, the option is not serialized.

### Reproduction of the problem

1. Define an AutoComplete with NoDataTemplate("")

2. Search for a non-existing option and notice how the popup opens and displays the default "No data found" message. When initializing the AutoComplete with jQuery and the "noDataTemplate" is set to "", the popup does not open.

A REPL sample for reproduction: https://netcorerepl.telerik.com/cfkPEClS50FUVU5z00

### Expected/desired behavior

When the NoDataTemplate("") is set and there are no results, the popup must not open. The NoDataTemplate option must work equally when using either the AutoComplete HtmlHelper or Kendo UI for jQuery AutoComplete.

### Environment

* **Telerik UI for ASP.NET MVC version: 2024.4.1112
* **Browser: [all]

Bug report

Reproducible with suggest: true and serverFiltering: true
Regression introduced in 2019.3.1023.

2. Type in "che".
3. Click the clear button.

Expected/desired behavior

The input is cleared.

Environment

• Kendo UI version: 2019.3.1023
• jQuery version: x.y
• Browser: [all]

In order to fix concerns from #241 (https://github.com/telerik/kendo-ui-core/issues/241) the Autocomplete now shows a full list of items when the text entered has been deleted.  This ignores the MinLength option, and can cause unresponsiveness in the browser (since MinLength is generally there to reduce the amount of results).  From #574 this new functionality is intentional (and as such, the thread was closed as won't fix), but in practical terms, this causes issues for a lot of people.  If you really don't want to enforce MinLength when 0 results are returned, perhaps adding an extraoption like 'AlwaysEnforceMinLength' would solve this problem

I was looking into why the data value of the Autocomplete control was not submitting to my controller via an ajax form and came across this article: https://www.telerik.com/forums/autocomplete-send-selected-dataitem-to-controller#-BRzEKVnbUyebqxFKYWpcA. Would it be possible in a future release to include a dataValueField option so that the value of the data item selected can be used by the controller? What's weird is this is not an issue when using the autocomplete control inside a grid. I was able to get the value and update my model.
