Hi Pat,
Thanks for the reply.
Just pure text. no images.
The Grid is rendering 2000 rows using a pagination grid panel.
it makes an RPC call to the server to retrieve the records and this is
how I am able to render it.
(i dont know how to use the code tag here in the forum, sorry)
<CODE>
if (getStore() != null) {
pagingToolbar.unbind(getStore());
getStore().removeAll();
}
PagingMemoryProxy proxy = new PagingMemoryProxy(data);
ArrayReader reader = new ArrayReader(recordDef);
Store store = new Store(proxy, reader);
pagingToolbar.bind(store);
store.load(0, pagingToolbar.getPageSize());
reconfigure(store, new ColumnModel(columns));
setStore(store);
</CODE>
