c# - Trying to define a 'View' for a control by using a scrollviewer. Different results between Silverlight but not WP7? -

-

i’m trying create simple image rotator control user can click arrow , image slide one. i’m doing stackpanel of images inside of scrollviewer.

n silverlight, following code works expected:

<grid x:name="rootlayout" margin="200" width="480">     <grid.rowdefinitions>         <rowdefinition height="50" />         <rowdefinition height="50" />     </grid.rowdefinitions>     <grid.columndefinitions>         <columndefinition width="50" />         <columndefinition width="50" />     </grid.columndefinitions>      <scrollviewer grid.row="0" grid.column="0" horizontalscrollbarvisibility="hidden" verticalscrollbarvisibility="hidden">         <stackpanel orientation="horizontal">              <stackpanel.rendertransform>                 <translatetransform x:name="tt" />             </stackpanel.rendertransform>              <stackpanel.resources>                 <storyboard x:name="sb">                     <doubleanimation                          storyboard.targetname="tt"                         storyboard.targetproperty="x"                         from="0"                         to="-50"                         duration="0:0:0.25" />                 </storyboard>             </stackpanel.resources>              <rectangle width="50" height="50" fill="blue" />             <rectangle width="50" height="50" fill="green" />         </stackpanel>     </scrollviewer>      <button content="push" click="test" grid.row="1" grid.column="1" /> </grid>

the "push" button begins storyboard.

now, when use same code in wp7 page, runtime error on begin method of storyboard saying targetname not resolved. interestingly enough, if remove scrollviewer wrapped around stackpanel completely, page runs fine. why fail on wp7 when stackpanel contained inside scrollviewer? (note root level of phone page phone:phoneapplicationpage)

thanks!

can't answer why there difference, when have been writing storyboards on wp7 reference transform want this.

storyboard.targetname="mystackpanel" storyboard.targetproperty="(uielement.rendertransform).(translatetransform.x)

perhaps there difference in traveral algorithms.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values?
