how set selected row in default when load gridpanel using checkbox selection model?

[ps_arunkumar]

hi,

i am using extjs 4.0.2a.

in gridpanel using Ext.selection.CheckboxModel.

my json data

({"totalCount": 5, "dataRows": [{"checked": true, "name": "User1", "date": "13/06/1982"},{"checked": false, "name": "User2", "date": "13/06/1983"},{"checked": true, "name": "User3", "date": "13/06/1984"},{"checked": false, "name": "User4", "date": "13/06/1985"},{"checked": false, "name": "User5", "date": "13/06/1986"}]} )

when gridpanel render check dataIndex checked is true or not. if true mean checkbox is checked otherwise not checked. is it possible to integrate this logic in Ext.selection.CheckboxModel.

i try this

listeners: {                        afterrender: function() {
                            var current_grid = this;
                            store.on('load', function(){
			    
                                var data = current_grid.getStore().data.dataRows;
				
                                var recs = [];
                                Ext.each(data, function(item, index){
				
                                    if (item.data.checked) {
                                        recs.push(index);
                                    }
                                });
				current_grid.getSelectionModel().selectRows(recs);
                               
                            })
                        }
                    }

Here is some code I used to select checkbox items in a grid:

this.gridB.getSelectionModel().on('select', function(selModel, model) {
    // make call to server to get subfields, data is created from gridB subfields list, not from table
    // table is used to check selected subfields below using ajax call on success
    Ext.Ajax.request({
        method: 'POST',
        url: 'index.php/mapper/get_tag_subfields/',
        scope: this,
        params  : {
            id: this.gridB.getSelectionModel().getSelection()[0].data.id,
        },
        success: function(xhr) {
            var json = Ext.decode(xhr.responseText); // make sure to decode for loadData to work

            // data is formatted, just need to load data
            storeMapperSubfields.loadData(json.data);
            // mark checkboxes
            if (json.data.length){
                for (var i = 0; i < json.data.length; i++){
                    var rec = this.gridC.store.getById(json.data[i].id); // json.data[i].getId()
                    if (rec.data.field_type == 's'){ // select all records have have 's'
                        this.gridC.getSelectionModel().select(rec,true,false);
                    }
                }
            }
        },
        failure: function() {
            Ext.getBody().unmask();
            alert('AJAX FAILURE: Unable to process call');
        }
    });
}, this);
