wpf - Bind width on UI element to Width of another UI Element -

-

i wanted bind width of column header width of header defined. code doesn't work. if specify width explicitly (width="100"), works fine. can shed light , tell me wrong code below?

<datagrid:datagridtemplatecolumn x:name="pdpcol" width="100">         <datagrid:datagridtemplatecolumn.header>             <grid horizontalalignment="stretch">                 <textblock text="pdp" verticalalignment="center" horizontalalignment="center"                      textwrapping="wrap" width="{binding elementname=pdpcol,path=actualwidth }" textalignment="center" />             </grid>         </datagrid:datagridtemplatecolumn.header> </datagrid:datagridtemplatecolumn>

remove horizontalalignment="center" textblock or set property stretch. textblock consume available width automatically. furthermore, if don't show else textblock, remove grid , use textblock. need set headertemplate rather header directly.

<datagrid:datagridtemplatecolumn x:name="pdpcol" width="100" header="pdp">     <datagrid:datagridtemplatecolumn.headertemplate>         <datatemplate>             <textblock text="{binding}" textalign="center" />         </datatemplate>     </datagrid:datagridtemplatecolumn.headertemplate> </datagrid:datagridtemplatecolumn>

best regards,

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (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...

(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."
