Is there something I can do to increase the speed that the tooltips popup with? 

It seems like the "ShowDelay" property in the RadToolTipManager would do it, but I have tried many settings and it always seems to take maybe 300 miliseconds. 

I got a sample program from another thread in these forums showing how to make a tooltip pop up when the RadInputManager throws an error.  That is working great and in the sample program the tooltips appear immediately.  I have configured my ToolTipManager exactly the same way, but mine have a delay where I would them to pop up immediately too.

Hello Kevin,

Would you please provide some additional information - do you use animation and also what is the exact slowing you mean - time before showing the popup or time of the process while being shown?

The ShowDelay property determines how many milliseconds after the popup is triggered it will show. As to the showing process itself, when using animation you can control it by using the AnimationDuration property which was recently introduced.

All the best,

I was using the "Fade" animation and it would seem to take a few moments before the fade animation started, regardless of my "ShowDelay" setting.

I do not have the "AnimationDuration" property you mention, but it seemed to me the delay was in starting the animation.

I have since changed the "Animation" property to "None" and I now get the popup to show immediately upon error.  That is the behavior I was looking for and I will simply not have an animation effect. 

If/When we update the product I will try it again and experiment with the additional properties.

Hello Kevin,

Since the animation is not as important for your setup as the fast showing indeed the best solution if you do not intend to upgrade is to disable the animation. Once you upgrade you will be able to use the animation and control its duration as well. In case you face any problems with the upgrade or you have additional questions do not hesitate to contact us again.
