i have such listbox below:
<listbox x:name="listbox" horizontalalignment="left" height="385" margin="21,138,0,0" verticalalignment="top" width="273" itemssource="{binding path=locationlist}"> <listbox.itemtemplate> <datatemplate> <stackpanel orientation="horizontal"> <button name="btndelete" click="btndelete_click" width="15" height="15" horizontalalignment="center" verticalalignment="center" verticalcontentalignment="center" horizontalcontentalignment="center" content="x" /> <checkbox name="checkbox" /> <textblock name="textbox" text="{binding}"/> </stackpanel> </datatemplate> </listbox.itemtemplate> </listbox> and set checkbox specific item listbox.
i trying it:
private void button4_click(object sender, routedeventargs e) { for(int = 0; < listbox.items.count; i++) { listbox.items[i].checkbox = false; } } i know doing error. cast object of item , set item's property (this checkbox) false. may correct me ? thank in advance.
edit:
before trying way:
foreach (var item in listbox.selecteditems) { item. } but possibilities have got standard methods: equals, gethashcode, gettype, tostring... how may refer checkbox ?
moreover supply question insight. find specific item text in line in listbox (item) , change checkbox item (same row in listbox). second logic implemented set rows selected or unselected (this trying now).
thank response.
(int = 0; < listbox.items.count; i++) { var item = listbox.itemcontainergenerator.containerfromitem(listbox.items[i]) listboxitem; var template = item.contenttemplate datatemplate; contentpresenter mycontentpresenter = findvisualchild<contentpresenter>(item); checkbox mycheckbox = (checkbox)template.findname("checkbox", mycontentpresenter); mycheckbox.ischecked = true; } likewise can find textblock (note, named "textbox" not "textblock")
textblock mytextblock = (textblock)template.findname("textbox", mycontentpresenter); findvisualchild can found here findvisualchild reference issue
