Hi, I have a fundamental question about the RadToolTip implementation.
In my application, I programmatically build a NxM matrix and use RadToolTip to provide additionnal information about the meaning of each intersecting cell. To fill the tooltip, I only need the row ID and column ID, the data itself is fetched from a database. The tooltip looks good, but since it generates a MS AJAX postback each time I hover over a cell, it greatly increases the load of the server as Page_Init() and Page_Load() are executed every time even thought very simple html is added to the tooltip.
My initial thoughts about the RadToolTip were that it would not use an MS AJAX UpdatePanel but a WebService to fetch the tooltip HTML. This WebService could be very light weight and thus, the performance would be not be hindered by the page complexity.
Can the tooltip data be fetched from a WebService at this time or is it only through the OnAjaxUpdate event? Wouldn't that be a nice feature to provide?
If impossible, how do you suggest I tackle my performance problem ?
Thanks
Dominic.
