Description

Steps to reproduce:
1. Open AdvancedDataGrid.as
2. Scroll to line 3000 in function "override protected function drawRowBackgrounds():void"
3. implementation is "drawRowBackground(rowBGs, i++, rowInfo[curRow].y, rowInfo[curRow].height, colors[d - 1], curRow);"
4. But the last argument "curRow" is not a dataIndex value;

Actual Results:

Same as in DataGrid.as

var actualRow:int = verticalScrollPosition;
var n:int = contentHolder.listItems.length;

while (curRow < n)

{ drawRowBackground(rowBGs, i++, contentHolder.rowInfo[curRow].y, contentHolder.rowInfo[curRow].height, colors[actualRow % colors.length], actualRow); curRow++; actualRow++; }

Where actualRow start index of verticalScrollPosition.

Expected Results:

If verticalScrollPosition equals to 41 the dataIndex should equals to 41 as well not to ZERO

Workaround (if any):

drawRowBackground(rowBGs, i++, rowInfo[curRow].y, rowInfo[curRow].height, colors[d - 1], actualRow);"
