  • Could you paste the xaml for your template and buttons?

  • Sorry, for some reason the alerts system flaked out for a few days in there, and I missed update notifications.  I'll take a look.

  • It looks like when you drag it to certain positions, mainly near the center point vertically or horizontally, Blend sets both margins (left/right or top/bottom) and sets the height/width to auto, and sets it to stretch.  Because your button template uses template binding for height/width, it picks up the auto value, and picks 0 as a size for the height or width.  There are several solutions, such as being sure your buttons have a height/width set.  Another more complicated solution would be to change your ellipses to not bind their height/width with template binding, but set them to auto and set them to stretch to fill with appropriate margins if needed.


    When I run your project the text "ListBoxItem" appears to be anti-aliased when magnified.  But I am running with it with the SL4 runtime, and I believe many changed have been made in the font rendering.  Could you post screenshots of what you are seeing?  (Zoomed in if possible)

  • It appears that you have a drop shadow on the box containing the text, when you apply an effect, SL can no longer do cleartype rendering, and has to fall back to non clear-type, which is probably what you are seeing.  You might be able to work around that by structuring it as 2 separate components in a grid:



    <rect with fill/rounded corners/shadow/>

    <TextBlock with text, transparent />
