Hi there,

My form has a combo box that is populated from a viewbag in a controller.  The Combobox isn't posting any data when the form is submitted however.  I don't get any errors but the values in the database are always null.  What have I done wrong?

 The Combobox Code

 

@(Html.Kendo().ComboBox()
      .Name("workscopecode")
      .DataTextField("Text")
      .DataValueField("workscopecode")                      
      .Filter(FilterType.Contains)
      .Placeholder("-- Select Duties --")
      .BindTo(ViewBag.duties))

 My Viewbag in my Controller Code

IEnumerable<SelectListItem> duties = mydata.tbl_workscopes
 
    .Select(c => new SelectListItem
    {
        Value = c.idx_index.ToString(),
        Text = c.code
    });
ViewBag.duties = duties;

Hello Allan,

The ComboBox widget has an input element with a name attribute equal to the Name specified in the widget's configuration. Basically, posting the form should include that input element, however it might not be bound on the server in case the Model has no field with matching name. You can check the browser's network tab and verify what is being posted. If that is indeed the case, then I would suggest either set a matching name or use the ComboBoxFor helper instead (without explicitly specifying the name). For example: 
@(Html.Kendo().ComboBoxFor(m=>m.SomeModelField) ... )

Hi Allan,

i dont know if you still got this issue.

keep in mind you'll need to add the deferred option on the combobox - like so:

@(Html.Kendo().ComboBoxFor(m => m.Contract.ContractName)
                                           .Name("ContractSelection")
                                           .HtmlAttributes(new { @class = "form-control", style = "width:100%" })
                                           .DataValueField("Id")
                                           .DataTextField("Text")
                                           .AutoBind(false)
                                           .Deferred()
                                           .DataSource(s =>
                                           {
                                               s.Read(r =>
                                               {
                                                   r.Action(MVC.Contract.ActionNames.LookupList, MVC.Contract.Name);
                                               })
                                               .ServerFiltering(true);
                                           })                                 
                                   )

 

hopte this helps
