Kendo UI Grid: Get the data of Current Grouping state?

fixed the issue. Will look into that further Use dataSource.group() to get the columns currently being grouped by:
code :
  $('#click').click(function() {
    var groups = [];
    var grid = $("#grid").data("kendoGrid");
    var gridgroups = grid.dataSource.group();
    for (var i=0; i< gridgroups.length; i++){
      groups.push(gridgroups[i].field);             
    }

    alert(groups);       
  })

will be helpful for those in need You need to set the model on radio button click to let the grid know that particular row has been set as dirty therefore fire update event with updated model values
so add this on radio button click..
code :
columns.Bound(x => x.IsActive).Width(46)
.ClientTemplate("<input type='radio' name='isActive' value='#= IsActive #' # if (IsActive) { # checked='checked' # } # onclick='radioBoxClick(this)' />")
    function radioBoxClick(e) {

        grid = $("kendoGrid").data().kendoGrid;
        var dataItem = grid.dataItem($(e).closest('tr'));
        var model = grid.dataSource.get(dataItem.UserId);          
        model.set("isActive", e.checked ? 1 : 0);        

    }

Kendo grid retrieves old data when grouping

wish of those help The resolution is clearing data from the grid itself and not the data source.
Calling the destroy method cleaned out all JQuery data attributes and I was able to repopulate the grid with the odd behavior.
code :
var grid = $('#report').data('kendoGrid');

if (grid) {
    grid.destroy();
}

Hope this helps In the Grid Header Template we have access to the group property that in turns contains all data items for the respective group under its items property.
You can pass them to the custom button click handler and proceed accordingly:
code :
<kendo-grid-column field="Category.CategoryName" title="Category">
            <ng-template kendoGridGroupHeaderTemplate let-group let-field="field" let-value="value">
            <strong>{{field}}</strong>: {{value}} <button class="k-button" (click)="onClick(group)">CLICK</button>
          </ng-template>
        </kendo-grid-column>

this will help It is understandable that this isn't a built-in feature. It is pretty complicated because if you have nested groupings, you would have to remember each collapsed group in the hierarchy that it existed in. Since items will be moving in and out of the DataSource, this would be a pain to track.
