Custom Widget user templating

[Matjaz]

My code is:

var MatjazChooser = kendo.ui.Widget.extend({

        init: function(element, options) {
            var that = this;

            kendo.ui.Widget.fn.init.call(that, element, options);

            that.wrapper = that.element;
            element = that.element;
            element.addClass('k-chooser');

            var template = that.options.template;
            if (template == "")
            {
                template = '<span class="k-button" data-group="# if (data.group != undefined) { ##=data.group##} else {#default#}#" data-uid="#= data.uid #">';
                template += '# if (data.imageUrl != undefined) { #';
                template += '<img src="#= data.imageUrl #"><br>';
                template += '#}#';
                template += '#= text #';
                template += '</span>';
            }
            that.template = kendo.template(template);

            that._dataSource();
        },

The important line is: data-uid="#= data.uid #
If the user (programmer) defines template without uid, the Widget will not work as expected.

How can I check if user define template with data-uid, or not? How can I added it, if not exists?

Hi Matjaz,

you can check how the same problem is resolved in the source code of the listview widgets (both mobile and desktop version).

Went through several times.
Any hint where to look?

Hi Matjaz,

The following method is how the mobile listview builds its template.
