I'm having awesome luck on here so I'll try another question. Thanks again for all of the help!
I'd like to hook up the Page Up and Page Down keys in a scroller with a repeater.
I have this markup in my scroll control UI, and not on the MCML page that's calling it (if that makes a difference). The arrow keys work but the page up and page down keys do not. Any ideas?
Code: Select all
<Locals>
<ScrollingHandler Name="ScrollingHandler" HandleDirectionalKeys="true" HandlePageKeys="true" HandlePageCommands="true"/>
<ScrollingData Name="ScrollingData"/>
<KeyHandler Name="PageUpHandler" Key="PageUp" />
<KeyHandler Name="PageDownHandler" Key="PageDown" />
</Locals>
Code: Select all
<Rules>
<Changed Source="[PageUpHandler.Invoked]">
<Actions>
<Invoke Target="[ScrollingData.PageUp]"/>
</Actions>
</Changed>
<Changed Source="[PageDownHandler.Invoked]">
<Actions>
<Invoke Target="[ScrollingData.PageDown]"/>
</Actions>
</Changed>
</Rules>

Did you give the repeater to the scrolling data and the scrolling data to the scrolling handler? In your rules section?
eg:
Code: Select all
<!-- Give ScrollingData to ScrollingHandler. -->
<Default Target="[ScrollingHandler.ScrollingData]"
Value="[ScrollingData]"/>
<!-- Give Repeater to ScrollingData. -->
<Default Target="[ScrollingData.Repeater]"
Value="[FavoritesRepeater]"/>

Also, if you haven't already I suggest you add this animation to your scroller for smoother scrolling
Code: Select all
<Scroller Orientation ="Vertical"
MaximumSize="0,400"
FadeSize="-30"
ScrollingData="[ScrollingData]">
<Animations>
<Animation Type="Move">
<Keyframes>
<PositionKeyframe Value="1,1,1" RelativeTo="Current" Time="0"/>
<PositionKeyframe Value="1,1,1" RelativeTo="Final" Time="0.5"/>
</Keyframes>
</Animation>
</Animations>
</Scroller>

Yep. Everything seems to be working except for the page up and page down keys. Could it be a focus issue? Is there a way I can ensure that the scroller gets the keys?

How about starting by making sure the keys are recognized in general. Add another action to the key press event to show a dialog to make sure the are firing.

Good idea. I'll give that a shot tonight. Thanks!

Thanks again for the help! I got it going on a vertical scroller by using ShortcutHandler instead of KeyHandler. However, when I put the exact same code in a horizontal scroller, it doesn't work. I changed the page down to pop a dialog box and that works. Are there different keys I should handle for a horizontal scroller? PageUp and PageDown don't really seem intuitive for a something that goes horizontal.
A little more information. I have a horizontal scroller that I'd like to page left and page right. Does the PageUp and PageDown methods of the ScrollingData element move a horizontal scroller left and right?

I've never tried to access the ScrollingData directly. I think when I've used the PageUp and PageDown handlers, I have them call a NavigateIntoIndex to get it to switch the focus to a particular item, then let the scroller move automatically.
