non editable dyn cell type

how to make dyn cell type non editable ???

You can disable editing for whole grid
    grid.setEditable(false);
for specified row
    grid.lockRow(rowID, true);
for specified cell
    grid.cells(rowId,cellInd).setDisabled(true);

Also more complex schemes can be applied by defining the onEdit event
handler which fires on each edit attempt, and returning false from which,
block edit operation.

mygrid.attachEvent(“onEditCell”,function(stage,id,ind){
    if (ind==INDEX) return false;
    return true;
}
where INDEX - index of column for which edit operation must be blocked

In case of dhtmlxTreeGrid you can disable editing for tree cells only
by using
    grid.enableTreeCellEdit(false);
