angular ng-grid: rowItem.rowIndex not map to index of data array after sorting

Finally, I found the way to get the corresponding index of array even when sorting is applied.

demo here: http://plnkr.co/edit/irVXdjAoCvAKPxQ1uD4P?p=preview

By using rowMap like this,

$scope.gridOptions.ngGrid.rowMap.indexOf(rowItem.rowIndex);

which is not documented, so beware that the future patches/updates may affect this implementation.

Updated: With further studies, I found that selectedItems with multiSelect equals to false may serves the same purpose. However, it won't work exactly the same if you need the grid with multiSelect:true.

thanks for your answer this was very usefull. To move the selection to the next row after deletion you could do it like this (single select)

// Step 01: remember current selected rowindex:

gridOptions.afterSelectionChange: function(row, event) {
$scope.gridOptions.rowIndex = row.rowIndex;}

// Step 02: delete row and move selection

$scope.deleteRecord = function() {
var arrayIndex = $scope.gridOptions.ngGrid.rowMap.indexOf(rowItem.rowIndex);
var rowIndex = $scope.gridOptions.rowIndex; `on sorted grids these to might differ`
var e = $scope.$on('ngGridEventData', function() {
    if (rowIndex >= $scope.gridItems.length) {
                    // last element is deleted, thus move selection up
        rowIndex--;
    }
    if (rowIndex >= 0) {
        $scope.gridOptions.selectRow(rowIndex, true); 
        $scope.focusRow(rowIndex);
        e(); // deregister the listener
        $scope.entity2View();
    }
});
$scope.gridItems.splice(arrayIndex, 1);});
