[SOLVED] How do i select a record in a grouped smartgwt listgrid?

How do i select a record in a grouped smartgwt listgrid?

I have site with a listgrid and a openlayers map with points. When i cklick on one of these, the application shall scroll and mark this record. This works with a standard listgrid, but with a grouped listgrid it does not work.

lg = new ListGrid();
lg.setWidth(330);
lg.setDataSource(ds1);
lg.setAutoFetchData(true);
lg.setSortField("KU_NAME");
lg.setGroupStartOpen(GroupStartOpen.ALL);
lg.setGroupByField("KU_NAME");
lg.setShowFilterEditor(true);

kuName = new ListGridField("KU_NAME", "K&uuml;nstler Name",150);

// Standorte
ListGridField stdOrt = new ListGridField("STDORT_NR","Standort Nr.");
ListGridField oid = new ListGridField("OID","OID.");
lg.setFields(stdOrt,kuName,oid);

and the select:

String stdortOID = stdOrtOIDjso.toString();
ListGridRecord[] records = lg.getRecords();
    int i;
    for (i = 0; i < records.length; i++) {
        if (records[i].getAttribute("OID").equalsIgnoreCase(stdortOID)){
            break;
    }
}
lg.deselectAllRecords();
lg.selectRecord(i);
lg.scrollToRow(lg.getRecordIndex(record));

the reason is that in the record is only the value of the group name and the other attributs are unavailable.

Solution

When grouping is enabled, all data are "transformed" into tree and listgrid itself contains data for groups so you have to look for your record in this tree. Replace last 3 lines with (modified) Vittorio Paternostro suggestion:

Tree tree = lg.getGroupTree();
if (tree != null) {
    TreeNode node = tree.find("OID", stdortOID);
    if (node != null) {
        lg.selectSingleRecord(node);
        lg.scrollToRow(getRecordIndex(node));
        lg.markForRedraw();
    }
}

Note: Instead of deselectAllRecords + selectRecord use simplified selectSingleRecord.
