I have an UltraWebGrid with one of the columns structured with DataType="System.DateTime" and Format="MM/dd/yyyy". I am attempting to insert a new row into this grid on the client side and have all of the other cells correctly working except this one. The code I am using for inserting a new row is as follows:

var gridID = '<%= grd1.ClientID %>';

var grid = igtbl_getGridById(gridID);

igtbl_addNew(gridID, 0);

//Get the newly inserted row

var rows = igtbl_getGridById(gridID).Rows;

var newRow = rows.rows[rows.length - 1]; 

To set a value for each cell in the grid I use the following line, obviously changing the cell index for each cell:

 newRow.cells[0].setValue(val);

When I try to insert a value into the DateTime row, the cell remains blank. I have tried the following and both don't work:

newRow.cells[2].setValue(Date.parse(new Date())); //Pass date object

newRow.cells[2].setValue(new Date());  //Pass seconds since epoch

What is the correct way to pass a value into DateTime cells?
