Ok, terrific

Thanks

In your Over function, it seems you have access to the cell...(cellID)

use the following to get the row

var cell = igtbl_getCellById(cellID);
var row = cell.getRow();

if you also need the row id...although you've already got a reference to the row object with getRow();

// continuing on from above
var rowId = row.Id;

that should be right for you to access the row when hovering...if you store the rowId, you will be able to tell when the mouse hovers over a new row instead of the cell in the same row, something  like this:

//outside of hover function
var lastHoverRowId;

// in hover function
if (lastHoverRowID !== rowId)  {

      // the mouse has changed to a new row
      doStuff();     

      // store the new rowId
      lastHoverRowId = rowId; // store the value
}

Terrific

While I have your interest, can you tell me how I would capture the 'row id' ?  I will use the approach you directed but i'm wondering how I will be able to capture the row id using these methods.

For instance, I know there is something for cells:

function Over(gridNane, cellID, objectType)
            {
                var cell = igtbl_getCellById(cellID);

...

But how about the rows??

Thanks!
