My text is getting cutoff in my Panorama View, I am wondering is there away to wrap the text or make it smaller so it won't get cutoff?
Thanks
Have you tried changing the TitleTemplate?
<phone:Panorama Title="my application">
<phone:Panorama.TitleTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" FontSize="50" Margin="0,50,0,0"/>
</DataTemplate>
</phone:Panorama.TitleTemplate>
</phone:Panorama>

I have a UserControl that needs to contain a bunch of controls on top and a LongListSelector below them. Total height of the whole UserControl may (and almost always will) exceed the screen height and in that case a whole UserControl must be scrollable.
My current setup is as follows:
<staff:UserContentControl
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:controls="clr-namespace:MyApp.Controls"
xmlns:staff="clr-namespace:MyApp.Helpers"
x:Class="MyApp.Controls.RemoteHomePage"
DataContext="{Binding RelativeSource={RelativeSource Self}}"
FontFamily="{StaticResource PhoneFontFamilyNormal}"
FontSize="{StaticResource PhoneFontSizeNormal}">
<ScrollViewer>
<ScrollViewer.Content>
<StackPanel>
<TextBlock Txt="Text1" Sign="#" />
<TextBlock Txt="Text2" Sign="#" />
<controls:Divider />
<TextBlock Txt="Text3" Sign="~" />
<TextBlock Txt="Text4" Sign="~" />
<controls:TextDivider Text="Divider text" />
<phone:LongListSelector ItemsSource="{Binding Items}">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}" />
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
</StackPanel>
</ScrollViewer.Content>
</ScrollViewer>
</staff:UserContentControl>
This solution satisfies my needs but also there's a big problem: currently LongListSelector takes really a lot of time to load when amount of items it contains is reasonably large. It takes 8 seconds to process 300 items and during that time the whole UI is blocked. If I remove everything but LongListSelector, like so:
<staff:UserContentControl
...>
<phone:LongListSelector ItemsSource="{Binding Items}">
<phone:LongListSelector.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}" />
</DataTemplate>
</phone:LongListSelector.ItemTemplate>
</phone:LongListSelector>
</staff:UserContentControl>
then LongListSelector loads almost immediately even with significantly larger amount of items. But obviously I need those other controls above it so the question is what can I do solve this issue?
(Also related question: I was worried that LongListSelector inside ScrollViewer could cause double scrolling or something like that but eventually everything turned out just fine in this regard. I'm not sure if LongListSelector somehow knows that it is inside other scrollable control or if something else happens that I'm not aware of. Some explainantion why it works fine, although very slow, would be much appreciated.)
Don't use scroll viewer since it will make the longlistselector think it has an infinitely tall screen available and render all its items.
Instead to solve your usecase use the Header and Footer properties to add data above or below your list items.
You can't force ScrollViewer to virtualize LongListSelector items.
So you need to mimic it behaviour by LongListSelector only.
Make the first item contains all you required elements form StackPanel (1'st itemtemplate). And other elements will be basic LongListSelector elements (2'nd itemtemplate).
Here is explanation how to set different templates to the items: Styling a selected ListViewItem in Windows 8 CP
I've got a page design as follows:
The layout is as follows:
<ScrollViewer Margin="0" HorizontalAlignment="Left" Height="360" VerticalAlignment="Bottom">
<StackPanel x:Name="spQueuedWeapons" HorizontalAlignment="Left" VerticalAlignment="Bottom">
<ItemsControl ItemsSource="{Binding QueuedCombinations}" HorizontalAlignment="Left">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Image Source="{Binding ImageName}">
<i:Interaction.Behaviors>
<ex:MouseDragElementBehavior ConstrainToParentBounds="False" />
</i:Interaction.Behaviors>
</Image>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</StackPanel>
</ScrollViewer>
The problem I'm seeing is that the MouseDragElementBehavior seems to be visually constrained to the bounds of the ScrollViewer.
I want to be able to drag the green boxes to the blue drop target.
The only options I've thought of so far have been to remove the containing ScrollViewer or to simulate the StackPanel layout programmatically.
I'd rather not add manual button based scrolling or programmatic layout if possible.
Does anyone have any ideas?
Just started with developing for WP7 and came across the following. I have a pivot application with a few pivotitems. On the first pivotitem (see code below) I want to be able to adjust a lot of settings. For this question all items to be set are called 'TextBox' and the choice in the ListPicker is either A,B or C.
Now if I do NOT use the ScrollViewer and I tap any of the listpickers I get to see all three options BUT I can not scroll through all listpickers.
If I DO use the ScrollViewer, I CAN see all listpickers but only the top one (that's visible) will expand and give me the options A,B and C, they others stay collapsed.
How can I get every listpicker to expand and show me the avaiable options AND be able to scroll to every listpicker on the page?
PS In code below copy the stackpanel between start and end about 15 times.
Thanks in advance for any help!
<controls:PivotItem Header="blabla">
<ScrollViewer>
<StackPanel Margin="0,0,36,0" VerticalAlignment="Top" d:LayoutOverrides="Width">
// start
<StackPanel Orientation="Horizontal">
<TextBlock TextWrapping="Wrap" Text="TextBox" Width="80" TextAlignment="Right" Margin="10,22,20,0" HorizontalAlignment="Right" VerticalAlignment="Top" />
<toolkit:ListPicker Margin="0" Width="275">
<toolkit:ListPickerItem Content="A"/>
<toolkit:ListPickerItem Content="B"/>
<toolkit:ListPickerItem Content="C"/>
</toolkit:ListPicker>
</StackPanel>
// end - copy/paste code code between start and end about 15 times right here
</StackPanel>
</ScrollViewer>
</controls:PivotItem>
This is, apparently, a common issue with Listpicker and ScrollViewer. You can find a workaround here
Should anybody stumble upon this, this has been fixed since the november 2011 release of the wP7 silverlight toolkit.
I have this code in my .xaml file
<ListBox Name="Tracks" Margin="0,0,-12,0" ItemsSource="{Binding AllTracks}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,17" Width="432" Height="150">
<TextBlock Text="{Binding Name}" TextWrapping="NoWrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
<TextBlock Text="{Binding Artist}" TextWrapping="NoWrap" Margin="12,-3,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
<TextBlock Text="{Binding Album}" TextWrapping="NoWrap" Margin="12,3,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
<TextBlock Text="{Binding Duration}" TextWrapping="NoWrap" Margin="12,6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I put data in my list like that(MediaLibrary library = new MediaLibrary();
Tracks.ItemsSource = library.Songs;).
I can see data on my list but when i select something, the selection doesn't highlighted,
how i can fix it? Thanks...
The phone applies the Accent colour as Foreground to the selected element's VisualTree. But since you're overriding the style for all the elements, it's likely that the colour won't be applied.
Try with a regular TextBlock without any Style, and you'll see.
Here: Windows Phone 7 - Setting style for specific control within selected ListBoxItem I've written a bit in response to a similar problem. Please read at least the original post/problem and my answer to it. It may look overwhelming at first as there's not a small amount of extra XAML, but in fact it is quite easy to follow and once you look at it as a several different aspects (template, styles, visualstates) - it turns out to be .. quite short, paradoxically. Once you read through it, you will probably notice that your problem is almost exactly the same, with the minor difference that the 'animated' property/target from foreground of textbox to a background of the panel..
This is the code:
<ItemsControl x:Name="ContactsControl" ItemsSource="{Binding Contacts}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Grid>
<TextBlock Text="{Binding ElementName=ContactsControl, Path=DataContext.PageName}" />
</Grid>
</Border>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
On the TextBlock I want to get date from the ItemsControl data context, so I use ElementName and in the 'Path' I use Path=DataContext.PageName.
So, On Blend I can see the data on the TextBlock as it should be, but when I run the emulator I cant see the data...
Why is it?
I'm working with VS2010 and Blend 4.
Thanks.
You are binding an items control to a list of Contacts. Traditionally you will then bind the textblock to a property of the class contained in the list. Why are you binding to another control and then bringing datacontext into the equation? Doesn't seem like something you normally do with a list.
