I just implemented load on demand on radtooltipManager which I load user controls into the manager in code behind.
Everything works wonderfully, but I have a question. One of my user control displays a dropdown with radtreeview with many nodes.
I can display loading image when the page loads the tooltip containing that user control so it's clear that it's loading, but when user closes the tooltip, it takes so much time before the tooltip is gone. My first impression is that tooltip is slower to close when the content is big in byte size.
What's your solution to solve this?
And do you have a way to cache the tooltip content so the 2nd time the system displays the tooltip, it will load faster?
