Yeah, that's what I figured. I didn't want to do that, though, because it seemed like it should be unnecessary.

I feel like I'm writing an entire button class. :-/

That sucks, and the thought had crossed my mind that depending upon the animation, you may or may not want that to happen.

Given that ... the only way I can see to retain the end point is to set it in the Completed function probably after calling stop();

Well, that kinda works! I just added a .stop() call before I set the targetname. Unfortunately, this leads to some choppiness in the animations at times.

I'll try the Completed event later - I just wanted to see if stopping the animation would keep it from breaking all of the time.

Edit: I tried the Completed event. Unfortunately, calling .stop() on the storyboard when it completes causes whatever end result I had planned to go away.

Ah, so really, we need to either just stop the animation first, or we need to check if it's going and then stop it.

Thanks for the tip! I'll check it out tomorrow.

I remembered something from the 'old' WPF/E days... and put together a really simple html/xml pair.

Here's the html:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Single Storyboard Test</title>
<script src="Silverlight.js" type="text/javascript"></script>
</head>

function MoveIt(sender, args)
{
   if (fDone == 1)
   {
      fDone = 0;
      var sWhich = sender.Name.toString();
      sender.findName("MoveIt")["Storyboard.TargetName"]=sWhich;
      sender.findName("MoveIt").Begin();
   }
}

function MoveDone(sender, args)
{
sender.findName("MoveIt").stop();
fDone = 1;
}
</script>

Click on one of the two balls to animate it. When it's complete, click either to repeat.

<br />
<center>
     <div id="Ag1Host" style="background:#FFFFFF">
        <script type="text/javascript">
           var pe1 = document.getElementById("Ag1Host");
        </script>
     </div>
</center>

</body>
</html>

and the xaml:

</Canvas>

Notice that in the Completed script, I 'stop' the animation, even though we all know it is stopped anyway... that's the sleight of hand that makes you be able to set the target again.

I added an additional flag to avoid crashes if you clicked the other ball while the one was still moving.

I'm having the same problem that Russ is having. However, my storyboards don't have a begintime - they only have a duration.

   function cnvInfo_MouseEnter(sender, args)
   {
    var sb = sender.findName("MouseEnter");
    sb["Storyboard.TargetName"] = "elInfo";
    sb.begin();
   }

I haven't extracted out a lot of the stuff, as I'm just trying this out, but the mouseover (err, mouseenter) only works once, and then breaks. If a have a mouseleave set as well, it breaks the first time and throws up two little alerts.

What are we doing wrong?

Russ...

I looked at this earlier this afternoon, and was wondering what the MouseLeave code did...

but just now I looked at it again, and I'm wondering if the issue might be the BeginTime=0?

since you're kicking that off with a message, I'm wondering if that's needed?

Just a thought...

AG_E_RUNTIME_SETVALUE : Storyboard.TargetName

RussD — Fri, 25 May 2007 21:45:35 GMT

I have a MouseOver event that calls this and a bunch of squares that have their color set dynamically. On the first MouseOver it works fine, but on the next one it bombs.
Any help?

//        var startNum = sender.name.lastIndexOf('r');
//        var endNum = sender.name.length;
//        var lbgNum = sender.name.substring(startNum +1, endNum);
//        // Retrieve a reference to the control.
//        var hostControl = sender.getHost();

//        // Retrieve a reference to the specified object.
//        var storyboard = hostControl.content.findName('Rect_Enter');
//        var linearBrush = hostControl.content.findName('lgb'+lbgNum);
//
//        if (storyboard)
//        {
//            if(storyboard["Storyboard.TargetName"] != linearBrush.Name)
//            {
//                storyboard["Storyboard.TargetName"] = linearBrush.Name;
//                storyboard.begin();
//            }
//        }
