c# - Different Kendo grid Datasource when grouping applied -


i have kendo grid, following decleration:

 @(html.kendo().grid<agencyautomation.domainlayer.viewmodels.invoicedetailviewmodel>()               .name("invoicedetailgrid")              .bindto((ienumerable<agencyautomation.domainlayer.viewmodels.invoicedetailviewmodel>)@viewbag.invoicedetails)               .columns(columns =>               {                   //                   columns.bound(p => p.accountid).hidden();                   columns.bound(p => p.stakeholderid).hidden();                   columns.bound(p => p.commissiontypeid).hidden();                   columns.bound(p => p.billdescription).hidden();                   columns.bound(p => p.groupno).hidden().clientgroupheadertemplate("<span  style='float:right'><button id='btngroupedit' onclick='showgroupedit(#=value#)'  class='btn btn-primary round_blue'><i class='fa fa-edit'></i>&nbsp;edit</button></span>");                   columns.bound(p => p.stakeholderdesc).filterable(true).sortable(true).title("stakeholder").groupable(true);                   columns.bound(p => p.stakeholdername).filterable(true).sortable(true).title("stakeholder name");                   columns.bound(p => p.amounttype).filterable(true).sortable(true).title("amount type");                   columns.bound(p => p.commissiontypedescription).filterable(true).sortable(true).title("commission type");                   columns.bound(p => p.commissionvalue).filterable(true).sortable(true).title("commission value").clienttemplate("#if (commissionvalue > 0){#<div>#=commissionvalue#</div>#} else {#<div></div>#}#");                   columns.bound(p => p.plancode).filterable(true).sortable(true).title("plan code");                   columns.bound(p => p.amount).filterable(true).sortable(true).title("amount").format("{0:c2}").clientfootertemplate("").clientgroupfootertemplate("<div> $#=sum#</div>").format("{0:c2}");                   columns.bound(p => p.groupno).hidden();                   // columns.bound(p => p.invoicedetailid).clienttemplate(gridrowicons).title("").filterable(false).width(90);                })              .pageable(pageable => pageable.buttoncount(5).pagesizes(true))               .filterable()                .selectable(selectable => selectable               .mode(gridselectionmode.single))               .navigatable()               .groupable(p => p.enabled(false))               .datasource(datasource => datasource                 .ajax()               .aggregates(aggregates =>             {                 aggregates.add(p => p.amount).sum();             })                      .group(groups => groups.add(p => p.groupno))                   .model(model =>                   {                       model.id(p => p.invoicedetailid);                   }))               .sortable()               .filterable()         )

based on grouping, based on 'groupno', want modify particular section on popup, remove existing rows group , replace new lineitems. without grouping applied, can access datasource ease , manipulate data. when access grid grouping applied, datasource length returns number of groups available member property containing field on grouping applied.

i tried removing grouping following command: grid.datasource.group([]) or grid.datasource.group("") not change datasource.

any advice? i'm little oblivious dealing grouping on kendo grid , apparently seems hard nut crack

i ran same problem , figured out solution works me. hope helps someone. ended enumerating groups , pushing items array ends looking ungrouped data. 

var grid = $("#gridadminconfig").data("kendogrid"); var groupeddata = grid.datasource.data(); var data = [];  //enumerate groups , grab actual items (var = 0; < groupeddata.length; i++) {  (var j = 0; j < groupeddata[i].items.length; j++) {     data.push(groupeddata[i].items[j]);  } }
