EditorTemplate:

<
div class="k-widget">
    @Html.HiddenFor(model => model.Id)
    <div class="edit-buttons">
        <a class="k-button k-button-icontext k-update-button" href="\\#"><span class="k-icon k-update"></span></a>
        <a class="k-button k-button-icontext k-cancel-button" href="\\#"><span class="k-icon k-cancel"></span></a>
    </div>
    <dl>
        <dt>
            @Html.LabelFor(model => model.SharedWith)
        </dt>
        <dd>
            @(Html.Kendo().MultiSelectFor(model => model.SharedWith)
                .DataValueField("Id")
                .DataTextField("Name")
                .Placeholder("Type user's name...")
                .DataSource(source =>
                {
                    source.Read(read =>
                    {
                        read.Action("Users", "User");
                    });
                })
                .TagTemplate("<div class=""tag-image""><img src=""#: Picture #"" height=""32"" /></div>")
                .ItemTemplate("<div class=""item-image""><img src=""#: Picture #"" height=""32"" /></div>"))
        </dd>
    </dl>
</div>
The list view display mode works fine, but as soon as I click edit, and it switches to the EditorTemplate, I get an error saying that Picture is undefined, even though the model that is being passed into the ListView constructor definitely has a fully populated SharedWith model.

Hello Matt,

The template seems to be specified for the MultiSelect widget in the editor. Does the result from the Users action method contain a field name "Picture"?

Yes, it does.

The EditorTemplate works fine when it's called from a view, but when it's triggered by clicking edit from the ListView, javascript gives an error saying that Picture is not defined.

Hello again Matt,

Thank you for confirming. It seems that the problem occurs because the expression is used in a nested template and is not evaluated in the correct context. Please try to escape the "#" characters in the multiselect template and let me know if you still experience this problem:

.TagTemplate("<div class=""tag-image""><img src=""\\#: Picture \\#"" height=""32"" /></div>")
.ItemTemplate("<div class=""item-image""><img src=""\\#: Picture \\#"" height=""32"" /></div>"))
