MultiColumnComboBox's selected value not sent to server when in Grid popup editor

[Emily]

I have a Grid with a custom popup editor. Inside the popup editor, I have a MultiColumnComboBox.

 

When I select a value in the MultiColumnComboBox and click Update button in the editor, the Update method does not get fired. When I console out e.model on the save event, dirty flag is false, dirtyFields is empty and contact_id is null.

 

@Html.LabelFor(model => model.contact_id)
@(Html.Kendo().MultiColumnComboBoxFor(model => model.contact_id)
                .AutoBind(false)
                .Placeholder("Select Contact...")
                .DataTextField("contact_number")
                .DataValueField("id")
                .Columns(columns =>
                {
                    columns.Add().Field("contact_number").Title("Id");
                    columns.Add().Field("contact_name").Title("Name");
                })
                .Filter(FilterType.Contains)
                .DataSource(source =>
                    {
                        source.Read(read =>
                            {
                                read.Action("SearchContact", "Manager").Data("getContactData").Type(HttpVerbs.Post);
                            })
                            .ServerFiltering(false);
                    })
                )

Hi Emily,

 

I examined the configuration and the MultiColumnComboBox should work as expected in the Grid. One thing that could cause the behavior is the way values are submitted. Would you set the ValuePrimitive option to true and see how the behavior changes?

Also, make sure that you are using the latest version of the components. The current official version is 2019.2.619.
