Grid Data merging

[blutarsky]

Hi everybody,

Is there a way using a HttpProxy class or similar, to load data from remote server and merging ( not to overwrite as do default ) the xml result into the existing data grid.

example:
first call:
2 rows returned
<items>
<item>
<idInstrument>0001</idInstrument>
<lastPrice>13</lastPrice>
</item>
<item>
<idInstrument>0002</idInstrument>
<lastPrice>20</lastPrice>
</item>
</items>

result grid
idInstrument lastPrice
001 13
002 20

second call:
only one row with already defined id in the first call:

<items>
<item>
<idInstrument>0002</idInstrument>
<lastPrice>30</lastPrice>
</item>
</items>


and so I would view

idInstrument lastPrice
001 13
002 30


thank a lot
best regards
