Visual Studio 2019, Kendo 2020.1.219, Net Core 3.1
I am trying to use a tag template to display the number of items selected rather that displaying the selected items. The multiselect gets the data correctly but when I select an item in the list I get an error saying 'values' is undefined. If I remove values it says maxTotal is undefined. Any idea what I am doing wrong or missing?
@(Html.Kendo().MultiSelect()
.Name("SBN")
.DataTextField("Text")
.DataValueField("Value")
.Placeholder("Select SBN...")
.TagTemplateId("SBNTagTemplate")
.TagMode(MultiSelectTagMode.Multiple)
.AutoClose(false)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("SBNMultiSelect_Read", "Report");
})
.ServerFiltering(true);
})
)
<script id="SBNTagTemplate" type="text/x-kendo-template">
#:values.length# out of #:maxTotal#
</script>

Hello Richard,
Thank you for the shared code snippets.
I was able to render the template correctly by switching the tagMode to single. Attached you will find a small project for reference.
Let me know if that would resolve the issue.
