Silverlight 4 Canvas.Left binding without canvas per item -

-

i'm getting performance issues code, mousing on canvas area laggy if leave in canvases within data template, no lag if take them out (but canvas.left bindings don't work ellipses in wrong place!) there way position these items without each 1 needing own canvas?

    <canvas>         <itemscontrol itemssource="{binding path=spatialdata.trainevents.arrdepellipseoflines}" name="ctrlcharttraineventsarrdep" >   <itemscontrol.itemtemplate>     <datatemplate>       <canvas>         <ellipse width="{binding eventshape.width}" height="{binding eventshape.height}" stroke="{binding path=stroke}" strokethickness="{binding strokethickness}" fill="{binding path=fill}" canvas.left="{binding canvasplacement.x}" canvas.top="{binding canvasplacement.y}" />       </canvas>     </datatemplate>   </itemscontrol.itemtemplate>  </itemscontrol> </canvas>

thanks much, becky

yes, can remove canvas in ellipse. think you'll find values canvasplacement.x don't increment per ellipse , effect seeing fact each element in itemscontrol placed in stackpanel (the default behaviour , can changed via itemspanel property) laying these out - in horizontal line.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
