c# - When using ListBox in WPF, how to get access to the selected value(s) programmatically -

in code i'm using list box display objects class i'm creating. want able click on item in list box , programmatically use selected item. items come dictionary shown below.

private dictionary<int32, myclass> collection;  public window1() {     listbox1.selectionchanged += new selectionchangedeventhandler(clickanitem);     listbox1.itemsource = collection; } 

now, works , listbox displays collection expect, , have event firing should, i'm stuck on how use selected value.

private void clickanitem(object sender, routedeventargs e) {     listbox list = sender listbox;     /** list has int32 , myclass object can't seem       *  them out of there programmatically      */ } 

i've tried casting listbox.selecteditems object of type dictionary no avail.

i didn't run it, here question seems similar. however, stay away editing xaml if possible. more can @ run-time better.

so question is, how access 'int32' , 'myclass' of selected item? i've used c# in past i'm jumping , has been bugging me on hour.

you need value selecteditem property on listbox , cast appropriate type. in case keyvaluepair<int32, myclass> makes dictionary

give try:

private void clickanitem(object sender, routedeventargs e) {    listbox list = sender listbox;     var selecteditem = listbox.selecteditem keyvaluepair<int32, myclass>; }
