Because of some scenarios the "#" chars are restriced. So I want to use other char instead of. May be we can set the openTag and closeTag instead of "#". For example, <% and %>, [% and %] etc. May be this is flexible.
This is not supported due to internal logic restrictions and unexpected side effects/issues if allowed. Still if you have template with hash tag values inside it, you can escape the inner has tags as explained here: http://docs.kendoui.com/getting-started/framework/templates/overview
