               icon   : url_servlet+'externals/gxp/src/theme/img/pencil.png', 
            tooltip: 'Редактировать участок',
            handler: function(grid, rowIndex, colIndex) {
            alert("DAMACIA!!!!");
           }

Answer 1

You have all you need in handler params

handler: function(grid, rowIndex, colIndex) {
            var row = grid.getStore().getAt(rowIndex);
            console.log(row);
           }

The code above will give you the row, so you just need to select desired cell.

If you enforce selection before clicking actioncolumn you can also use code below. But be aware by default clicking on actioncolumn doesn't fire selection, so while clicking actioncolumn an entirely different row can be selected or even no column can be selected at all.

grid.getSelectionModel().getSelection()
