Not able to find element on dynamic created item in Silverlight

[Rocky Fan]

I got one issue on using WebAii 2.0 for testing Silverlight.

Environment: WIn7 x86 + VS 2010 RC. Silverlgiht 3.0 was build in VS2010 too.

Test case do :
  Launch browser
  Find the Silverlgiht in page and find its combobox inside, then select the combobox item.
  After combobox item was select, the product Silverlgith will grab new items to a listbox and filled the listbox.

All above steps work fine. And after the listbox items were filled, I can get find list box control, but from listbox control, I cannot find the listboxitem which were dynamic created!

 

 

 

ListBox listbox = app.FindName<ListBox>("lboxMetaDimensions");

 

IList

 

 

<ListBoxItem> listBoxItems = listbox.Find.AllByType<ListBoxItem>();

The listBoxItems == null.

I try to look into the all children items in all deepth levels recursively, and the result shows it does not contain listboxitem at all. Actually, when I use other Silverlight tool to inspect the v-tree, I can see the listboxitem.

Is any step I need to do after combox selection done and new item were filled in order to get new listboxitem?

Thanks.

Hello Rocky Fan,

The framework may have an old copy of the Visual Tree if you say they are visible in the tree on another tool. Pleast try either:

app.VisualTree.Refresh();
ListBox listbox = app.FindName<ListBox>("lboxMetaDimensions");
IList <ListBoxItem> listBoxItems = listbox.Find.AllByType<ListBoxItem>();

or

ListBox listbox = app.FindName<ListBox>("lboxMetaDimensions");
listbox.Refresh();
IList <ListBoxItem> listBoxItems = listbox.Find.AllByType<ListBoxItem>();
