hi
thanks for the response Anton,
i have got the solution from this forum. This is the code for updating
modified grid data.
Record[] records = gridPanel.getStore().getModifiedRecords();
String[] fields = gridPanel.getStore().getFields();
ArrayList<Map<String, String>> modifiedRecords = new
ArrayList<Map<String,String>>();
for(int i = 0; i < records.length; i++) {
Map<String, String> parameters = new HashMap<String,
String>();
for(int j = 0; j < fields.length; j++){
parameters.put(fields[j],
records[i].getAsString(fields[j]));
}
modifiedRecords.add(parameters);
}
if we pass the ArrayList<Map<String, String>> object modifiedRecords,
there we got the modified records in server side. there we can update
in database..
Thanks and Regards,
K. Venkat Kumar
