How can I see whether a scrollviewer child element is visible, and make it visible if it isn't?



In a scrollviewer I have a textblock with 1000 inlines e.g.


XAML


<Grid>
<ScrollViewer>
<TextBlock Name="textBlock1" TextWrapping="Wrap" />
</ScrollViewer>
</Grid>

C#


public MainWindow()
{
InitializeComponent();
for (int i = 0; i < 1000; i++)
{
textBlock1.Inlines.Add(new Run("Inline number " + i.ToString() + ". "));
}
}

How do I see if a particular inline element (e.g. number 850) is vis

I've already tried all of the existing posts related to this, but they doesn't work as I want it...

jQuery toggle doesn't change child element.style of visible elements when parent and child both toggled?
Programming Languages

In jQuery - I have a visible parent and child element - both have the same class.


If I toggle() using the class as the selector the child's style isn't updated to display: none; - even though it has the selector.


However if I have a hidden element and a hidden child element - both with the same class - both element.styles are updated to display: block; upon toggle(). When toggled a second time the now visible elements act in the same way as the original visible elements and the child's element.style isn't updated to show that it is hidden.

Hibernate. Enitity created in main thread isn't visible from child one
Programming Languages

I found strange hibernate behavior and I cannot explain it.


If I create an object in default thread inside transaction and make manual flush
then I cannot find it in other thread.


If I create an object in one special thread with the same conditions then everything is all right.


Here is the code that I described above:


// transaction template with propagation required
ttNew.execute(new TransactionCallbackWithoutResult() {
@Override
protected void doInTransactionWithoutResult(TransactionStatus status) {

Visible='<%# UserCanEdit %>' – if set to true inside Page_Load, then control isn't visible
Programming Languages

User control defines a property named UserCanEdit:


private bool _userCanEdit=false;
public bool UserCanEdit
{
get { return _userCanEdit; }
set { _userCanEdit = value; }
}



This User Control also contains the following GridView:


<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="C" runat="server" Visible='<%# UserCanEdit %>' Text="Visibility"></asp:Label>

STarting Using External Classes - and added Child isn't visible. Please Help!
 
Ok I am finally making the plunge and trying to create External Classes for everything.
It is working most of the time but then something that should work just doesn't work and turns my brain to jelly.
So in my Main.as
I instantiate (as kidzonemenu_mc) a Class KidZonePg1MC, which is just Movie Clip with a button and some text. I add an event listener to the button so that calls a method which removes kidzonemenu_mc and adds in its place an instance (home menu_mc) of the HomeMenu class.
This works fine - here is the code.
