dynamic row template with Grid in MVVM structure

[Wesley]

Hi,

I am trying to work on the grid like below,

 basically i give a checkbox to user, when it is not checked, the grid only display data from URL1,
but if the checkbox is checked, it merge 2 json data and display the comparison of URL1 and URL 2

<label><input type="checkbox" name="compCB" id="compCB">Enable Compare</label>
<div id="grid" style="height: 365px"></div>
<script>
$(document).ready(function () {
  var url1="http://XXXXXXXXX/clients/1";
  var url2="http://XXXXXXXXX/clients/2";
  var J1=null;
  var J2=null;
  var Jdata;
  var toCompare;
  loadData('init');

  function loadData(act){
    toCompare =$('#compCB').is(':checked');
      if(act=='init'||act=='reload'){
        $.getJSON(url1, function(jd) {
          J1=jd;
          meargeData();
        });
      };
      if(toCompare){
        $.getJSON(url2, function(jd) {
          J2=jd;
          mergeData();
        });
      }else if(act='toggle'){
        J2=null;
        mergeData();
      };
    };
    function mergeData(){
      if(J1!=null&&(J2!=null||!toCompare)){
        if(!toCompare){
          Jdata=[{
            clientId: J1.clients[0].clientId,
            name: J1.clients[0].name,
            status: J1.clients[0].status
          }];
        }else{
          Jdata=[{
            clientId: {
              C1: J1.clients[0].clientId,
              C2: J2.clients[0].clientId
            },
            name: {
              N1: J1.clients[0].name,
              N2: J2.clients[0].name
            }, 
            status: {
              S1: J1.clients[0].status,
              S2: J2.clients[0].status
            }
          }];
        };
        genGrid();
      };
    };
    function genGrid(){
      if(!toCompare){
        RT='<tr data-uid="#= uid #"><td>#: clientId #</td><td><strong>#: name #</strong></td><td style="text-transform:lowercase;">#: status #</td></tr>';
        ART='<tr data-uid="#= uid #" style="background-color:rgb(255,200,255)"><td>#: clientId #</td><td><strong>#: name #</strong></td><td style="text-transform:lowercase;">#: status #</td></tr>';
      }else{
        RT='<tr data-uid="#= uid #"><td>#: clientId.C1 #<br/>#: clientId.C2 #</td><td><strong>#: name.N1 #<br/>#: name.N2 #</strong></td><td style="text-transform:lowercase;">#: status.S1 #<br/>#: status.S2 #</td></tr>';
        ART='<tr data-uid="#= uid #" style="background-color:rgb(255,200,255)"><td>#: clientId.C1 #<br/>#: clientId.C2 #<br/></td><td><strong>#: name.N1 #<br/>#: name.N2 #</strong></td><td style="text-transform:lowercase;">#: status.S1 #<br/>#: status.S2 #</td></tr>';
      };
      $("#grid").kendoGrid({
        dataSource: {
          type: "json",
          data: Jdata,
          pageSize: 3,
        },
        groupable: true,
        sortable: true,
        resizable: true,
        columnResizeHandleWidth: 6,
        pageable: {
          refresh: true,
          pageSizes: true,
          buttonCount: 5
        },
        columns: [{
          title: "ID",
          width: 200
        }, {
          title: "Client Name",
          width: 250
        }, {
          title: "Status"
        }],
        rowTemplate: RT,
        altRowTemplate: ART
      });
    };
    $('#compCB').change(function(){
      loadData('toggle');
    });
  });
</script>

Now, I am trying to do it in the MVVM structure, the first problem I face is how do I change the  rowTemplate and altRowTemplate dynamicly?

Hello Wesley,

Please check this forum thread as it discusses how to change Grid's row templates after widget initialization.
Please note that you cannot change the template through MVVM, the approach requires manual change.
