  It should be a problem with model binding. Please take a look at the request parameters of the http request header.

  Please share your controller code and parameter model.

  Thanks for responding.

  Since my initial email I've tried to use the standard MVC DropDownList (Multiple) and I'm getting similar problems so the issue isn't Telerik specific.

  Here's the code for the standard MVC dropdown I'm using

  @Html.DropDownList("caseConditions", (MultiSelectList)ViewBag.Categories, new { multiple = "multiple" })
  

  If CaseConditions is a String it just saves only 1 item.

  If CaseConditions is a String[] I get an error. The same shown as before.

  Before sending more code, has anybody had any success using any standard MVC Multi select with ASP Net Zero?

  If so, how did you manage to Post the selected items without errors or only having 1 item saved?

  the model binding fails when you save the data, please share the http request header information of your submitted data and the parameter model corresponding to the method of saving the data.

  What is the model of the CreateOrEdit method? If you can use the ABP template project (<a class="postlink" href="https://aspnetboilerplate.com/Templates">https://aspnetboilerplate.com/Templates</a>) to reproduce this error, please send me a look at the project.

  Many thanks for your offer of help. I've spent about 4 hours stripping my app down to the bare bones so that I can send you a representative example of the problem.

  The email has just been sent to you along with a WeTransfer file as the app is too big to attach to an email.

  @richardghubert if you are using ASP.NET Core & jQuery version, then this is the best option I guess.
