i've started WP7 development about a week ago (and programming in general) and I've been working on a little app, but i faced a problem with getting ScrollViewer to function properly.
Application creates a new pivot item when certain conditions are met, and i'm trying to add a scrollable textblock in it, which shows randomly chosen strings of text from a list every time user taps the screen, from which some are long enough to require vertical scrolling.
// A bit cleaned version of my code,
// had to translate stuff a bit for them to make sense
// Sets the PivotItem header depending on user choice
// and creates ScrollViewer and TextBlock
PivotItem newPivotItem = new PivotItem { Header = choice, Name = "newPivot"};
ScrollViewer newScrollviewer = new ScrollViewer();
TextBlock newTextBlock = new TextBlock { Text = "tap the screen", Name = choice};
newScrollviewer.Content = newTextBlock;
newPivotItem.Content = newScrollviewer;
mainPivot.Items.Add(newPivotItem);
Text is added in Tap event, which just replaces the Text property with new string. Text updates just fine and as intended, but ScrollViever stops working after update.
newString = list[rand];
PivotItem selectedPivot = mainPivot.SelectedItem as PivotItem;
TextBlock selectedText = selectedPivot.FindName(choice) as TextBlock;
selectedText.Text = newString;
selectedText.Height = selectedText.ActualHeight;
Similiar ScrollViewer - TextBlock combination in another PivotItem which is declared in xaml works just fine.
