I imagine you're showing the Datagrid in the Panel for the UnitTest. Keep in
mind that it uses a VirtualizingStackPanel, so if there's no visible area, I
would expect that no rows will be created (althoug I would at least expect
to have a DataGridRowsPresenter) so I'm not sure if that could be the
I got it working in the end, and it did seem to be an absence of data
causing the prob which makes sense. no data, no rows. :)
I then had to figure out how to invoke the click event of a togglebutton. I
endedup Toggling the togglebutton and changed the event from click event to
Checked/Unchecked.
Strange, Not getting a DataGridRowsPresenter or any children from the
datagrid in the unit test. I think I need to look at what data is in it, and
somehow mock it (so it's still a unit test and not an integration test). The
viewmodel data object its binding to is pretty complicated. I just want
eno
With the class that I send you you can use the Extension method GetChildren
(for UIElements), use the recursive overload to find a ToggleButton, it
should look something like
datagrid.GetChildren(true);
This will return an IEnumerable of all the ToggleButtons in the DataGrid.
This might include t
Something useful is to do Linq Queries.
from b in element.GetChildren
where b.Name == 'someName' && b.Tag = myExpectedValue
select b
You could even restrict it a bit, to discard other buttons in other places
(like toggle buttons in the header).
from r in dg.GetChildren()
from c in r.GetChildren
Check in SilverlightSpy. Use Cotrol+Shift+Mouse Over to find it and look at
the Visualtree, then use one of the GetChildren overloads in this class to
find it
public
static class VisualTreeExtensions
{
public static IEnumerable GetChildren(this
DependencyObject depObject)
{
int count = depObj
