  • Grid grouping missing rows #102961

    a2m developer

    I have a list of 7 rows.

    Case 1
    I group by a common value (all rows)
    Group only has 6 rows, but has count of 7 in group header.

    Only 6 rows shown in group of 7

    Case 2
    I group by unique value (all groups should have 1 row)
    Can see all the groups when closed
    Expand any group and rows disappear

    Groups closed

    Rows and Groups missing

    It seems that the height of the visible area on the grid is not updating to accommodate the change in grouping.

    My Environment
    Angular 5.2.5
    Jqwidgets 5.5.0

    My Source

    this.source = new jqx.dataAdapter(
            root: "data.data",
            record: "content",
            id: this.id,
            type: 'GET',
            url: url,
            unboundmode: true,
            mapChar: ',',
            datatype: 'json',
            datafields: this.dataFields,
            ref: this, //reference to list.component
            autoBind: false,
            processData: this.processApiLink.bind(this),
            beforeLoadComplete: this.beforeLoadComplete.bind(this),
            loadError: function (jqXHR, status, error) {
            loadComplete: function (data) {
              this.totalrecords = data.count;

    My Grid Componenet

          columns: this.columns,
          source: this.createSource(),
          virtualmode: true,
          width: this.options.width,
          height: this.options.height,
          selectionmode: this.options.selectionmode,
          groupable: this.options.groupable,
          groups: (this.groups ? this.currentGroups : []),
          //groupsexpandedbydefault: this.options.groupsexpandedbydefault,
          groupsexpandedbydefault: false,
          autoshowfiltericon: this.options.autoshowfiltericon,
          altrows: true,
          //autorowheight: (this.groups ? false : true),
          autorowheight: false,
          rowsheight: 30,
          autoheight: false,
          filterable: this.options.filterable,
          sortable: this.options.sortable,
          pageable: true,
          pagesize: (this.widgetData['PAGINATION'] ? this.widgetData['PAGINATION'] : 50),
          pagesizeoptions: [25, 50, 100, 500, 1000],
          pagermode: 'default',
          columnsreorder: this.options.columnsreorder,
          columnsautoresize: true,
          columnsresize: this.options.columnsresize,
          enableellipsis: false,
          theme: this.theme,
          scrollmode: 'logical',
          horizontalscrollbarstep: (this.columns.length > 10 ? 200 : 10),
          horizontalscrollbarlargestep: (this.columns.length > 10 ? 1000 : 50),
          showaggregates: (Object.keys(this.aggregates).length > 0 ? true : false),
          showgroupaggregates: this.options.showgroupaggregates,
          showstatusbar: (Object.keys(this.aggregates).length > 0 ? true : false),
          rendergridrows: function (a) {
            return a.data;

    Please Help… You’re my only hope. 😉

    Grid grouping missing rows #102963

    a2m developer

    I was able to hack it to see all the rows. On Group Changed and Group Expanded events I added:
    this.source.totalrecords = this.source.totalrecords + (this.grid.getrootgroupscount() * 2);

    Yep.. hack didn’t work completely. Now I can’t select multiple rows, unless I remove the group and add it back in. Strange. Help please!

    Hello a2m developer,

    I saw that you try to use grouping in combination with virtualmode.
    Unfortunately, such a combination is not possible.
    Please, take a look at this topic.

    I found a way. Seems to be working, but I am not using the editing feature as is the topic you referenced.

    hi a2m developer,

    do you mind share your solution? I also have the same issue with you and cannot remove the virtualmode for some reason.
