I got a problem with the Kendo UI MVC DropDownList. I want to do server side filtering. When I click on the control, the list gets populated. This works fine if the current selected item is in the populated list.
But what if I have an address book and the current selected name is "Zorro". I have thousands of names before and when I click on the list, only the first 10 names starting with "A" are shown.
How do I include the currently selected item in the DataSource, so it remains selected if I click on the dropdownlist?
Here is my code:
Razor:
@(Html.Kendo().DropDownListFor(m => m.Id) .DataValueField("Id") .DataTextField("DisplayName") .Filter("contains") .DataSource(source => { source.Read(read => { read.Action("PopulateNames", "PhoneBook"); read.Type(HttpVerbs.Post); }) .ServerFiltering(true); }))Controller:
[HttpPost]publicActionResult PopulateNames(stringtext){ var q = TblName.Query(n => n.ClientId.IsEqualTo(Manager.One.ClientId), n => n.DisplayName.Asc()); if(text != null&& text.Length > 2) q.Filter(n => n.c.DisplayName.IsLike(text)); q.Top(10); var rows = q.FetchList<NameLookupViewModel>(); rows.Insert(0, NameLookupViewModel.Default); returnJson(rows);}
