    The current findItemByText client-side function looks for items with exact text match. Is it possible to use it (or another function) more like a "StartsWith" function?

    Hello Jc,

    In order to achieve the desired functionality you should develop a custom method implementing it, there is no build in function available.

    You can use JavaScript method  indexOf   to check if a text starts with a given string.
    Using JavaScript you can find the RadListBox control by its ID, after that get the items of the RadListBox  and make a loop over them to check  if the text of an item contains the string given as an argument.

    string.indexOf(searchstring, start) - returns -1 if no match is found.
    *string - the string you search in (in our case item's text).
    *searchstring - the string you are searching for.
    *start - the position from which you want to start the searching (ex. if start=0 the searching starts from the first letter of the string).

    Best wishes,
