Attempted upgrade to 2018.1.226

[Allann]

I tried to upgrade this sample to your latest version and replace the html editors with tag helpers, but failed with the first control in the _layout.cshtml page.

                        <kendo-dropdownlist 
                                            name="dimensions" 
                                            bind-to="@{new List<SelectListItem> { new SelectListItem { Text = "Default", Value = "common" }, new SelectListItem { Text = "Bootstrap", Value = "common-bootstrap" } }}" 
                                            datatextfield="Text" 
                                            datavaluefield="Value" 
                                            on-change="javascript:function() { window.kendoThemeChooser.changeCommon(this.value(), true);}">
                        </kendo-dropdownlist>

                        @*@(Html.Kendo().DropDownList()
                        .Name("dimensions")
                        .DataTextField("Text")
                        .DataValueField("Value")
                        .Value("common-bootstrap")
                        .Events(e => e.Change("function() { window.kendoThemeChooser.changeCommon(this.value(), true);}"))
                        .BindTo(new List<SelectListItem>() {
                              new SelectListItem() {
                                  Text = "Default",
                                  Value = "common"
                              },
                              new SelectListItem() {
                                  Text = "Bootstrap",
                                  Value = "common-bootstrap"
                              }
                          })
                        )*@

This will not generate the correct code and also states:

Element 'kendo-dropdownlist' cannot be nested inside element 'label'.
