TypeError: Cannot read properties of null in ListBox when EnableMarkMatches is true

In our application we use ListBox with property EnableMarkMatches set. When we enter a search criteria with the keyboard you see in the selected rows the search criteria Bold. (See attached screenshot)

When u click with the mouse on this bold search criteria you get an error message in the console of the browser:

 

RadListBoxScripts.js:1223 Uncaught TypeError: Cannot read properties of null (reading 'get_enabled')

    at c.RadListBox._onClick (RadListBoxScripts.js:1223:6)

    at HTMLLIElement.<anonymous> (RadListBoxScripts.js:476:4)

    at HTMLDivElement.dispatch (jQuery.js:3:12445)

    at r.handle (jQuery.js:3:9174)

Hi Hans,

I have good news the issue will be fixed in the upcoming R2 2023 SP1 release, scheduled for July 19.

As a small note of gratitude for reporting it, I also updated your Telerik points.
