[LOHAMANOJ SIVAKUMAR]

Hi Imran,

I have attached my part of the code.




var treeConfig = [{
        nodeType: "gx_baselayercontainer",
 expanded: true
}, {
        nodeType: "gx_overlaylayercontainer",
        expanded: true,
        loader: {
            baseAttrs: {
                radioGroup: "foo",
                uiProvider: "layernodeui"
            }
        }
    }];

    treeConfig = new OpenLayers.Format.JSON().write(treeConfig, true);
    tree = new Ext.tree.TreePanel({
        border: true,
        region: "west",
        title: "Layers",
        width: 200,
        split: true,
        collapsible: true,
        collapseMode: "mini",
        autoScroll: true,
        plugins: [
            new GeoExt.plugins.TreeNodeRadioButton({
                listeners: {
                    "radiochange": function(node) {
 info = new OpenLayers.Control.WMSGetFeatureInfo({
            url: 'http://90.0.0.129:8090/geoserver/wms',
            title: 'Identify features by clicking',
     layers: [node.text],
     queryVisible: true,
     eventListeners: {
                getfeatureinfo: function(event) {
                    mapPanel.map.addPopup(new OpenLayers.Popup.FramedCloud(
                        "Info.,",
                        mapPanel.map.getLonLatFromPixel(event.xy),
 null,
                        event.text,
                        null,
                        true
                    ));
                }
            },
        });
                    }
                }
            })
        ],
        loader: new Ext.tree.TreeLoader({
            applyLoader: false,
            uiProviders: {
                "layernodeui": LayerNodeUI
            }
        }),
        root: {
            nodeType: "async",
            children: Ext.decode(treeConfig)
        },
        rootVisible: false,
        lines: false
    });
