kendo ui multiselect remove delete action

问题

How can i restrict users from deleting the already saved items in the Multi select widget. Users should not be able to delete existing values but can add or remove the new values.

The solution i tried was on databound remove the delete icon like below. It gets deleted but comes back after the call executes the databound method.

Any ideas?

onDataBound: function (e) {
        e.preventDefault();
        $(e.sender.tagList).find("li span.k-delete").remove();
    }

This is the code in the view which calls the above js function on databound

 @(Html.Kendo().MultiSelectFor(x => x.Documents)
                      .DataTextField("Description")
                      .DataValueField("Code")
                      .Placeholder("Select Attachment...")
                      .AutoBind(false)
                      .DataSource(source => source.Read(read => read.Action("GetCustomerDocuments", "CustomerRequest")).ServerFiltering(true))
                      .HtmlAttributes(new {style = "width:400px;"}) 
                      .Events(e => e.DataBound("onDataBound"))                            
                      )  

回答1:

Have your tried applying the same method on the change event as on the databound event?

Razor:

.Events(e => e.Change("onChange"))

Javascript:

onChange: function (e) {
    e.preventDefault();
    $(e.sender.tagList).find("li span.k-delete").remove();
}
