PreLoad the Window Sprites?

[sitefinitysteve]

Is there a built-in way to preload the image sprites so they don't "pop" in when an alert or something comes up?

Hi Steve,

You can try showing a RadWindow when the page is loaded with Top or Left property set to a high, negative value (Top="-10000"). This way the customers will not see the opened window but the resources will be loaded.

I would then have to re-position it when it opens though right?

Or perhaps store current, load it Top left, hide it, and put it back where it was?

Hello Steve,

I'm assuming he is saying to create add a second RadWindow to your RadWIndowManager, which you won't use, a have it appear where the user will not see it. If you do it that way, you don't have to worry about repositioning the RadWindow you are actually going to use.

I hope that helps.

I really don't want to use any resources I don't have to, so a second window is out of the question :)

Since it's a custom skin, if I just load the image sprite into a div way out of the viewable range that should work too, no?

Any update on this by any chance?

The RadMenu now as a EnableImagePreloading property to fix this issue

Hello Steve,

Yes, using a DIV with a custom skin to load the image sprite should work as well. As for such property for RadWindow, we will consider the pros and cons of such approach for the control, but for now I cannot tell if or when we will implement it.
