Adjust alternating row colors after delete

I would rather not refresh as it takes times and changes the position of the grid (even if you set focus).

How do you get the current background color setting of a particular row. If I can test against that I can get it, but my attempts to find that answer have proved fruitless.

found the solution

for (var i=line_number_deleted; i<rowcount i++){
obj.getRowTemplate(i).refresh();
}

yes, you could also try refreshClasses() method instead of refresh(). Also if you are using large grid with virtual scrolling than it make sense to stop at the last rendered row - test for obj.getRowTemplate(i).element(). You should also use row index instead of display position - those two might be different after sorting.

var obj = new AW.UI.Grid;
obj.setCellData(function(col, row){return col + "." + row});
obj.setHeaderText("header");

obj.setColumnCount(10);
obj.setRowCount(1000);

document.write(obj);


// delete row on double click
obj.onRowDoubleClicked = function(event, rowIndex){

    var rowPosition = this.getRowPosition(rowIndex);

    this.deleteRow(rowIndex);

    var rowCount = this.getRowCount();
    var rowIndices = this.getRowIndices();
    var i, index;

    for (i=rowPosition; i<rowCount; i++){
        index = rowIndices ? rowIndices[i] : i;
        this.getRowTemplate(index).refreshClasses();

        if (!this.getRowTemplate(index).element()){
            break;
        }
    }
}

Thanks refreshclasses is much faster and looks cleaner.
