how to smart save changed data in Grid back to DB? I means just save changed value without modifing all values in DB? after changed some values in Grid, the function serialize() wrote back all values in Grid, how could i just get the changed ones without getting all?
You can adjust serialize functionality by
grid.setSerializationLevel
for example next command will produce XML serialization which include only rows which has changed cells, and such cells will have “changed” attrubute
grid.setSerializationLevel(false,false,false,true,true);
var z=grid.serialize();
