Refresh Grid within a Tab

Is there an easy way to refresh a Grid within a Tab?
I tried the following with no luck:
//This works fine outside a tab
gridTable.request();
grid.refresh();
//This reloads the tab but not the grid data
TabsFrame.element().innerHTML = page[3].join('');

Need more information (your source code) in order to tell exactly what you are doing. Issuing a grid.refresh() should work. Let us see more source code and we might be able to help you.

The actual code would have been very convoluted because I was using dynamically generated code and an XMLHTTPRequest() handle to do the update. So, as I was trying to create a simple case, I realized that it was the XML file that was not getting updated and the gridTable.request() works fine after all.

Glad you found it.
