This example demonstrates integration between RadGrid, RadToolTip and RadAjaxLoadingPanel. The example shows how to insert several new records in the grid with a single button click using Ajax requests.

The control, containing the fields for the new records is added to the content of the RadToolTip when the AjaxUpdate event of the RadToolTipManager fires. Once the user hits the Add Products button, the new records are inserted into the datatable, the active tooltip is closed and the the appropriate nested table is rebound.
As you cannot use the Ajax of the RadGrid when you are using the RadToolTipManager, you can display a separate RadAjaxLoadingPanel when you are making Ajax requests.

Note that in order to see the new records, you have to expand the corresponding item in the MasterTableView.
