I am updating the Slideshow PlayInterval with a SliderControl. I have the SlideShow in an UpdatePanel and all is working fine EXCEPT the entire slide show starts over when I change the slider. I would like ONLY the PlayInterval property to update and the SlideShow to continue from the image it is displaying.
Does anybody know if this is possible?? If so, any suggestions....
Thanks,
Jim
Hi Jim,
You may save current image index in a hiddenfield before the PlayInterval is updated, and restore it after that.
For instance:
before:
var index = $find("behaviorIDofSliderShow")._currentIndex;
after:
$find("behaviorIDofSliderShow")._currentIndex = index;
Raymond,
I am thinking this is C# code. I am using VB and the $find isn't working. I am using something like:Index = SlideShowExtender1.BehaviorID.IndexOf() but can't figure out what goes in the brackets because the $find doesn't work...
Wonder if you can help me out in a VB sort of way?
Thanks,
Jim
Jim,
It's javascript, which runs on the client. It should be embedded in the html source directly. Below is an example of using javascript:
