Hi Jeff,

Thank you for the reply and for sharing your solution. Just as a note, the above code can be implemented in the grid's Initialize client-side event in order to iterate through the grid rows only once upon loading the page.

Please do not hesitate to contact me if you need further assistance.

Hi David,

In my function, I was trying to pass in a values using the .add() function.  I've actually come up with something that seems to work - I'll post it in case it is valuable to other memebers looking to do something similar.

var

grid = $find("grid");

var rows = grid.get_rows();

var max_ID = 0;

for (var i = 0; i < rows.get_length(); i++) {

    var  row = rows.get_row(i);

    if (row.get_cell(0).get_value() >= max_ID) {

        max_ID = row.get_cell(0).get_value() + 1

    }

}

This loop insures I generate a unique ID for my grid - and I'm now about to add multiple rows clientside in batch update mode.  Since my grids are only likely to contain 100 or less rows, I'm ok with the performance hit here and I can set default values for the other columns of my grid.

Thanks,

Jeff
