ExtJS 3.4 - Select row after load store of my gridpanel

My grid panel:

new Ext.grid.GridPanel({
    title: "Utilisateurs",
    layout: 'fit',
    style: marginElement,
    columns: mesColonnesUtil,
    id: 'gridPanelUtil',
    width: '70%',
    colspan: 2,
    collapsible: false,
    layout: 'fit',
    autoWidth: true,
    monitorResize: true,
    height: 200,
    store: storeUtil,
    stripeRows: true,
    selModel: new Ext.grid.RowSelectionModel({
        singleSelect: true
    }),
    listeners: {
        click: function () {
            this.selModel.getSelected();
        }
    }
});

My store:

var storeUtil = new Ext.data.JsonStore({
    proxy: proxyGrUtil,
    baseParams: {
        method: 'storeUtil',
        gr: ''
    },
    autoLoad: true,
    fields: ["Nom", "Prenom", "LDAPUser"],
    root: "rows",
    totalProperty: "total",
    successProperty: "success"
});

My combobox with select event, I load my grid panel with params:

{
    xtype: 'combo',
    store: storeGrUtil,
    id: 'comboGrUtil_GrUtil',
    width: 300,
    valueField: "id",
    displayField: "lib",
    triggerAction: 'all',
    mode: 'local',
    listeners: {
        select: function () {
            Ext.getCmp('gridPanelUtil').store.load({
                params: {
                    gr: Ext.getCmp('comboGrUtil_GrUtil').getValue() // this the value of items selected combobox
                }
            })
        }
    }
}

After this event, I can't select a row in my grid panel, why ? I don't understand.

you need to use the selectionModel of the grid, maybe you can pass a callback when calling load to the store

store.load({
    callback: function(records, operation, success) {
        //operation object contains all of the details of the load operation
        //records contains all the records loaded
        console.log(records);
    }
});

the you can call

grid.getSelectionModel( ).select(object/index);
//you need to pass record instance or index

The problem is the call of the load event of the store. You have to execute the row selection in this event and not after the call. If I remember well, the grid is completely loaded in this event. Take a look of the code tag above.

If it not working, I suggest to take a look at other event. Maybe with rowinserted of the gridView.

    var storeUtil = new Ext.data.JsonStore({    proxy: proxyGrUtil,
        baseParams: { method: 'storeUtil', gr: '' },
        autoLoad: true,
        fields: ["Nom", "Prenom", "LDAPUser"],
        root: "rows",
        totalProperty: "total",
        successProperty: "success",
        listeners: 
            load: function(e, records, options){
                 Ext.getCmp("gridPanelUtil").getSelectionModel().selectRow(maLigneASelectionner);
            }
        }
});
