c# - Working with elements inside a control that is bound to a collection -

-

i have observablecollection<string> bound itemscontrol template button. content of button 2 textblock. i'm trying use previewmouserightbuttonup event of button toggle visibility of 1 of textblocks, without being able use xaml names elements in template i'm hitting wall. there way of getting button's content elements via sender in preview event, or other way of doing this? related previous question had didn't quite usable answer (probably due explanation, hence simplified example). seems me should happen should make control based off button adds property toggle, thought had in previous question wasn't working. feel property , trigger right way go?

xaml:

<itemscontrol x:name="ic" >     <itemscontrol.itemtemplate>         <datatemplate>             <button previewmouserightbuttonup="button_previewmouserightbuttonup">                 <dockpanel>                     <textblock text="normal" dockpanel.dock="top"/>                     <textblock text="{binding}" dockpanel.dock="top" visibility="collapsed"/>                 </dockpanel>             </button>         </datatemplate>     </itemscontrol.itemtemplate> </itemscontrol>

code behind:

observablecollection<string> x = new observablecollection<string>(); public mainwindow() {     x.add("1");     x.add("2");     initializecomponent();     ic.itemssource = x; }

if name hidden text block "secondtextblock", should work:

private void button_previewmouserightbuttonup(object sender, mousebuttoneventargs e) {     dockpanel dockpanel = (dockpanel)((button)sender).content;     textblock text = (textblock)logicaltreehelper.findlogicalnode(dockpanel, "secondtextblock");     if (text != null)     {         text.visibility = visibility.visible;     } }

regarding comment below: yes, multiple instances of "secondtextblock" created. see snoop screenshot below. these multiple instances ok; not have negative impact.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
