Bug:
If you use a MultiSelectFor in an EditorTemplate, the grid's "save" event will only fire once for that cell.  The second time you update the same cell (by picking an additional item or removing an item from the MultiSelect list), the grid's save event is not called.

columns.Bound(c => c.HTMLAttributes)
  .Title("HTML Attr").Sortable(false).Filterable(false)
  .EditorTemplateName("HtmlAttributes");

EditorTemplate (AppCache.HtmlAttributes is a server array of a custom object)
@model object
 
@(Html.Kendo().MultiSelectFor(m => m)
    .Name("HtmlAttrList")
    .Animation(false)
    .DataValueField("ID")
    .DataTextField("Text")
    .BindTo(AppCache.HtmlAttributes)
 )

@(Html.Kendo().Grid<Field>()
                    .Name("fieldGrid")
                    .Columns(columns => ....)
                     
                    .Scrollable(scrollable => scrollable.Virtual(true))
                    .Sortable()
                    .Filterable()
                    .Editable(e => e.Mode(GridEditMode.InCell))       
                    .AutoBind(false)
                     
                    .Events(e => e
                        .Edit("myEdit")
                        .Save("mySave")
                    )
                    
                    .DataSource(ds => ds
                        .Ajax()
                        .ServerOperation(false)
                        .Model(model =>
                        {
                            model.Id(c => c.Name);
                            model.Field(c => c.Name).Editable(false);
                        })

Hello Curt,

The Grid widget does not support and it is not intended to edit nested arrays out-of-the-box. You can use the work-around from this code library project to enable such support:

I don't understand what using a MultiSelect as a column editor has to do with "nested arrays".  Does the grid support using the Kendo MultiSelect as a column editor?  If so, then shouldn't the grid "save" event always be called when updating the column value by using the MultiSelect?

OK, I now understand what you are saying.  The MultiSelect produces an array and that's not supported as a column editor when editing inline or inCell.

Is there a document that tells me what Kendo widgets are or are not supported in the grid?  Please don't leave it up to your customers to guess.

Hello Curt,

MultiSelect is the only widget which value is actually an array. DatePicker, DropDownLists , ComboBoxes, inputs, color pickers are all single values. For the specific case with the MultiSelect we have created the code library article.

How do you get the Editor to come up with the selected items already highlighted?

Hello Neil,

If the multi select inputs in the edit template are named as the properties in the model, the multi select will bound automatically to the values in the properties.

Please refer to the attached sample (custom-editor.zip) which illustrates how multi selects bind to the property with the same name.
