    var centerRegion = Ext.getCmp('centerRegion');
    centerRegion.remove(centerPanel, true);
    centerRegion.add(streamer);
                
                });
    In firebug the error is thrown my js. I have tried a lot but no luck.

    Thanks,
    amist

  2. i think you code looks fine but
    <code> var pos =grid.getSelectionModel().getSelection();</code>
    gets typeError because the "grid" is not a gris its just an event wich is a click event....so u should do

    var pos=panel.getSelectionModel().getSelection();
    console.log(pos);////this will display the selected row as total as an object and you can do what ever u like with it....


    listeners: {
    'afterrender': function(grid) {
    grid.body.on('click', function(event,innner) {
    alert('onclick');
    console.log(grid);


    /**************************************************************/
    var pos = grid.getSelectionModel().getSelection();
    console.log(pos);
    // record = grid.store.getAt(pos.row);
    // colname = panel.getHeaderCt().getHeaderAtIndex(columnIndex).dataIndex;
    // alert(cellvalue);
    /*******************************************************************/

    });
    }
