c# - WPF ComamndBinding Help on MenuItem -

-

new wpf...was reading wpf routed command bindings per-tab , close getting working.

the menuitem disabled until ruletab (tabitem) selected rather pop find dialog shows system.windows.input.commandbinding on menu. doing wrong?

xaml:

<menuitem header="_find..." isenabled="{binding elementname=ruletab, path=isselected}" >                     <commandbinding command="find" executed="executefind" canexecute="find_canexecute" ></commandbinding>                 </menuitem>

code-behind:

       private void executefind(object sender, executedroutedeventargs e)     {         // initiate finddialog         finddialog dlg = new finddialog(this.ruletext);          // configure dialog box         dlg.owner = this;         dlg.textfound += new textfoundeventhandler(dlg_textfound);          // open dialog box modally         dlg.show();     }      void dlg_textfound(object sender, eventargs e)     {         // find dialog box raised event         finddialog dlg = (finddialog)sender;          // find results , select found text         this.ruletext.select(dlg.index, dlg.length);         this.ruletext.focus();     }      private void find_canexecute(object sender, canexecuteroutedeventargs e)     {         e.canexecute = ruletab.isselected;     }

any suggestions appreciated!

figured out! responded. had move commandbinding to:

<window.commandbindings> <commandbinding command="find" executed="executefind" canexecute="find_canexecute" ></commandbinding> </window.commandbindings>

then reference command=find in menuitem.

you'll find need add commandbinding tabitem (as per linked sample). bind menuitem should use command property, possibly along commandparameter , commandtarget (pointing @ tabitem expect).

for example, have menuitem in contextmenu , want command fire on context (placement target) of contextmenu:

<menuitem header="view"            tooltip="open member central view member"           command="{x:static local:commands.customerviewed}"            commandparameter="{binding path=placementtarget.datacontext, relativesource={relativesource findancestor, ancestortype={x:type contextmenu}}}"            commandtarget="{binding path=placementtarget, relativesource={relativesource findancestor, ancestortype={x:type contextmenu}}}" />

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
