many thanks for your answer. I have a grid with some dropdown list and some rules coded on client js. The grid is in the mode where you have a different color empty row below  with some default values. The ddl's on the virtual new row work. if I go and fill some cells and then go to a different row in the grid, the row get's added becoming part of the "white rows",  What i was asked to do if to reproduce the same behavior when we while  located in the new row press enter. No much luck so far.... here an example of what i was trying.

function UltraWebGrid1_EditKeyDownHandler(gridName, cellId, key)
{
    //if the key is different than enter i'll exit
    if (key != 13)
        return;
    //If the cellId is not in the format gridnamer_somenumber i'm not in
    // the new empty row, so i'll exit the function
    var parts = cellId.split("_");
    if (parts.length!=2)
        return
    
    // up until here it works what should i do next?
    // I want the current row to became a "normal" row, and
    // a new row with a different color should appear in the
    // exact way it happens if i hit the arrow up....
    // i've tried  two things so far
    
    //igtbl_addNew(gridName,0,true,true);
    // the above will add a new not inizialized row
    //(there are many defaults values missing)  below and
    // everything will freeze up
    
    // i also tried to emulate the arrow up behavior by doing
    //var nRows=grid.Rows.length-1;
    //oldCell=grid.Rows.getRow(nRows).getCell(1);
    //grid.setActiveCell(oldCell);
    
    // it actually works but the focus is in the wrong row, and the
    // other scripts and ddl don't work, the values get updated in the

//wrong places.

it is nothing like newrow.addtogrid or grid.rows.add(currentrow) ??

thank you
