this header template:

    <script id="best-in-klas-products-header-template" type="text/x-kendo-template">     # if ( klas.bestinklasproductsviewmodel.checkforbestinklas(value) ) { #     <div class="list-view-group-header">         <div class="group-header-table-container">             <div><img src="images/best-in-klas.svg" class="best-in-class-logo" /></div>             <div>                 <div class="market-segment-title">#: klas.marketsegmentname #</div>                 <div class="award-title">best in klas</div>             </div>         </div>     </div>     # } else { #     <div class="list-view-group-header">         <div class="group-header-table-container">             <div><img src="images/category-leader.svg" class="best-in-class-logo" /></div>             <div>                 <div class="market-segment-title">#: klas.marketsegmentname #</div>                 <div class="award-title">category leaders</div>             </div>         </div>     </div>     # } # </script>

is there way show additional data in group header? appreciated.

instead of defining template groupheader, can define function call. inside function can whatever need , return whatever want header say.

headertemplate: headertemplatefunction,

with function like

function headertemplatefunction(e) {   var matcheddata = $("#listview").data("kendomobilelistview").datasource.data().tojson().filter(function(item) {     return item.continent === e.value;   });    return e.value + " has total of : " + matcheddata.length; }
