Use of WrapPanel - windows-phone-7

I have to wrap a content in text block which is in the stack panel. The following XAML code is
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Width="300">
<Image Height="160" HorizontalAlignment="Left" Margin="0,0,-400,0" VerticalAlignment="Top" Width="175" Source="{Binding thumb}"/>
<!--ContentControl Width="150" Height="110" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="0,0,-400,0" Content="{Binding Image}"/>-->
<TextBlock TextWrapping="Wrap" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="190,-167,-200,0" Text="{Binding title}"/>
<TextBlock TextWrapping="Wrap" VerticalAlignment="Top" HorizontalAlignment="Left" Margin="190,-135,-200,0" Text="{Binding page}"/>
<TextBlock FontSize="15" TextWrapping="Wrap" Height="Auto" Margin="190,-95,-200,0" Text="{Binding Name}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate
When i specify the width of the text block the text wrap works in the vertical and horizontal orientation.
I want the text to wrap in the vertical view only and in the horizontal view the text should not wrap without mention the textblock width.
for example in vertical view the list box width is small so the text should be:
match is between India and
pakistan
in horizontal view..I need it in single line
match is between India and pakistan.
Thanks in Advance!

Adaptive List View Help (Windows Universal App)

Below is my xaml code which defines ListView. The output is series of products. But the problem is the product aligns one after another.
I Want an output align vertically one after another.
<ListView x:Name="list" Margin="0,0,0,0" SelectionChanged="list_SelectionChanged" VerticalAlignment="Top">
<ListView.Resources>
<DataTemplate x:Key="myCell">
<Border BorderBrush="Gray" BorderThickness="0,0,0,0" >
<Grid Margin="0" x:Name="tryadpative" >
<Grid.RowDefinitions>
<RowDefinition Height="8*" />
<RowDefinition Height="1*" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<Image x:Name="prodimg" Width="auto" Source="{Binding prodimg}" Grid.Row="0"></Image>
<TextBlock x:Name="productcode" TextWrapping="Wrap" Text="{Binding productcode}" HorizontalAlignment="Center" Width="auto" FontSize="12" Grid.Row="1" Foreground="Gray"/>
<TextBlock x:Name="productname" FontSize="14" HorizontalAlignment="Center" VerticalAlignment="Bottom" Foreground="Gray" Grid.Row="0" Text="{Binding productname}" />
<TextBlock x:Name="productmindec" TextWrapping="Wrap" HorizontalAlignment="Center" Text="{Binding productmindec}" Width="auto" FontSize="14" Grid.Row="2" Foreground="Gray"/>
<!--<Image x:Name="prodimg" Width="auto" Source="{Binding prodimg}" Grid.Row="0"></Image>
<TextBlock x:Name="productcode" TextWrapping="Wrap" Text="{Binding productcode}" Width="auto" FontSize="12" Foreground="Gray"/>
<TextBlock x:Name="productname" FontSize="14" Foreground="Gray" Text="{Binding productname}" />
<TextBlock x:Name="productmindec" TextWrapping="Wrap" Text="{Binding productmindec}" Width="auto" FontSize="14" Foreground="Gray"/>-->
</Grid>
</Border>
</DataTemplate>
</ListView.Resources>
<!--<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>-->
<ListView.ItemTemplate>
<StaticResource ResourceKey="myCell"/>
</ListView.ItemTemplate>
</ListView>
ItemsStackPanel can be used only as the ItemsPanel of an ItemsControl that displays more than one item at a time. It can't be used with an ItemsControl that displays only one item at a time, such as a ComboBox or FlipView. ItemsStackPanel is the default ItemsPanel for ListView.
By default, the ItemsStackPanel stacks items vertically from top to bottom. You can set the Orientation property to Horizontal to stack items from left to right.
For more info, see ItemsStackPanel.
We should be able to set the Horizontal to the Orientation of the ItemsStackPanel.
For example:
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsStackPanel Orientation="Horizontal" >
</ItemsStackPanel>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
By the way, if you want scroll the ListView in horizontal, you should be able to set the Visible to ScrollViewer.HorizontalScrollBarVisibility and Enabled to the ScrollViewer.HorizontalScrollMode in ListView.
For example:
<ListView x:Name="list"
Margin="0,0,0,0"
SelectionChanged="list_SelectionChanged"
VerticalAlignment="Top"
SelectionMode="Single"
ScrollViewer.HorizontalScrollBarVisibility="Visible"
ScrollViewer.HorizontalScrollMode="Enabled">
</ListView>

AUTOCOMPLETE SUGGESTIONS APPEARS ON TOP OF TEXT BOX -WINDOWS PHONE

I am using auto complete textbox from windows phone toolkit.I need the list of suggestions below my textbox but it shows up above the text box .How do I make the suggestions appear below the text box..Here is my XAML.
<Grid Margin="0,336,0,189" x:Name="editrow" Visibility="Visible">
<Grid.RowDefinitions>
<RowDefinition Height="auto"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="220" ></ColumnDefinition>
<ColumnDefinition Width="100"></ColumnDefinition>
<ColumnDefinition Width="100"></ColumnDefinition>
</Grid.ColumnDefinitions>
<toolkit:AutoCompleteBox x:Name="newname" FilterMode="StartsWith" IsTextCompletionEnabled="True" Foreground="White" Background="#53000000" BorderThickness="0" Grid.Column="0" Grid.Row="0" Margin="10,0,0,0" IsDropDownOpen="True" RenderTransformOrigin="0,0">
<toolkit:AutoCompleteBox.ItemTemplate>
<DataTemplate>
<StackPanel Background="Gray" Orientation="Horizontal">
<TextBlock Text="{Binding }"/>
</StackPanel>
</DataTemplate>
</toolkit:AutoCompleteBox.ItemTemplate>
</toolkit:AutoCompleteBox>
<TextBox x:Name="rowquantity" Foreground="White" Background="#53000000" BorderThickness="0" Grid.Column="1" Grid.Row="0" InputScope="Number"></TextBox>
<toolkit:ListPicker Grid.Row="0" x:Name="units" Foreground="White" BorderThickness="0" Background="#53000000" Grid.Column="2" ExpansionMode="FullScreenOnly" Margin="12,5,0,14" >
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0 0 0 0">
<TextBlock Text="{Binding}"
FontSize="32" LineHeight="1"/>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>
<Button Content="Add" BorderBrush="#53000000" Foreground="#53000000" Grid.Column="1" Grid.ColumnSpan="2" Grid.Row="1" HorizontalAlignment="Right" VerticalAlignment="Top" Height="74" Click="Button_Click" Margin="0,0,3,0" Width="158"/>
</Grid>
The location of the popup is determined based on the available size. If there's more space above the AutoCompleteTextBox, it will pop up. You can see this in the popuphelper.cs source file where the code arranges the popup.
There really isn't an option to override the behavior.

Error when using <Scrollviewer> xaml

I am trying to use a but am getting the error:
The property 'Content' is set more than once.
It dissappears if I remove any one of the two lines of code in between the tags.
So neither of them seems wrong individually, but both together cause the problem.
<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<!--TitlePanel contains the name of the application and page title-->
<StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
<TextBlock x:Name="ApplicationTitle" Text="New Trip" Style="{StaticResource PhoneTextNormalStyle}" Height="40" />
<Button Content="Back" Height="71" Name="button1" Width="103" HorizontalContentAlignment="Stretch" VerticalAlignment="Top" HorizontalAlignment="Right" Click="button1_Click" />
</StackPanel>
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ScrollViewer>
<TextBlock Height="60" HorizontalAlignment="Left" Margin="65,12,0,0" Name="textBlock1" Text="Username" VerticalAlignment="Top" Width="169" />
<TextBox Height="78" HorizontalAlignment="Left" Margin="60,60,0,0" Name="textBoxUsername" VerticalAlignment="Top" Width="274" />
</ScrollViewer>
</Grid>
</Grid>
ScrollViewer can only have 1 content, so wrap the controls inside the ScrollViewer in a container like Grid, DockPanel, StackPanel
<ScrollViewer>
<StackPanel>
<TextBlock Height="60" HorizontalAlignment="Left" Margin="65,12,0,0" Name="textBlock1" Text="Username" VerticalAlignment="Top" Width="169" />
<TextBox Height="78" HorizontalAlignment="Left" Margin="60,60,0,0" Name="textBoxUsername" VerticalAlignment="Top" Width="274" />
</StackPanel>
</ScrollViewer>
Put your <TextBlock> and <TextBox> within another container, such as a StackPanel.

ScrollViewer scrolls back on WP7

I have created a page where there's alot of input from the user. So the User should be able to scroll down to be able to press a Upload button. To scroll down on the page I have used a ScrollViewer outside a grid. I am able to scroll but the page keeps scrolling back after scrolling down.
Here is my code:
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanelButtom" Grid.Row="1" >
<ScrollViewer >
<Grid x:Name="ContentPanel" Background="black">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="154" />
<ColumnDefinition Width="326" />
</Grid.ColumnDefinitions>
<Image Height="109" HorizontalAlignment="Left" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="167" Margin="23,19,0,0" Source="{Binding Path=ImageSoruce, Mode=TwoWay}" Grid.ColumnSpan="2" />
<TextBox Height="71" HorizontalAlignment="Left" Margin="12,161,0,0" Name="nameInput" Text="{Binding Path=Name, Mode=TwoWay}" VerticalAlignment="Top" Width="430" Grid.ColumnSpan="2" />
<TextBlock Height="56" HorizontalAlignment="Left" Margin="23,134,0,0" Name="nameLabel" Text="Name" VerticalAlignment="Top" Width="130" FontSize="25" />
<TextBlock FontSize="25" Height="60" HorizontalAlignment="Left" Margin="23,238,0,0" Name="descriptionLabel" Text="Description" VerticalAlignment="Top" Width="130" />
<TextBox Height="72" HorizontalAlignment="Left" Margin="12,265,0,0" Name="descriptionInput" Text="{Binding Path=Description, Mode=TwoWay}" VerticalAlignment="Top" Width="430" IsEnabled="True" Grid.ColumnSpan="2" />
<TextBlock FontSize="25" Height="60" HorizontalAlignment="Left" Margin="23,343,0,0" Name="locationLabel" Text="Location" VerticalAlignment="Top" Width="130" />
<TextBlock Height="46" HorizontalAlignment="Left" Margin="24,384,0,0" Name="locationInput" Text="{Binding Path=Location, Mode=TwoWay}" VerticalAlignment="Top" Width="401" Loaded="locationInput_Loaded" Grid.ColumnSpan="2" />
<toolkit:ListPicker SelectionMode="Multiple" FullModeHeader="CATEFORIES" x:Name="ListPickerCategories" CacheMode="BitmapCache" HorizontalAlignment="Left" Margin="25,492,0,0" VerticalAlignment="Top" Width="401" Grid.ColumnSpan="2" ItemsSource="{Binding Categories}" Height="78"></toolkit:ListPicker>
<TextBlock FontSize="25" Height="60" HorizontalAlignment="Left" Margin="24,436,0,0" Name="textBlock1" Text="Categories" VerticalAlignment="Top" Width="130" />
<Button Content="Upload" Height="86" HorizontalAlignment="Left" Margin="26,604,0,0" Name="UploadButton" VerticalAlignment="Top" Width="411" Click="UploadButton_Click" Grid.ColumnSpan="2" />
</Grid>
</ScrollViewer>
</Grid>
What can be the cause of this problem and how do I solve it?
Use StackPanels to put elements one below the other. Remove all your margins, height, width and other absolute positioning stuff
<Grid x:Name="ContentPanelButtom" Grid.Row="1" >
<ScrollViewer>
<StackPanel>
<!-- elements here -->
</StackPanel>
</ScrollViewer>
</Grid>
I had the same issue. but at last i solved it, i just used the Height property to do this. Please do the following steps
First create a ScrollViewer
Indide the ScrollViewer create a container(eg: Grid/StackPanel/Border etc...) and put every controlls inside it.
Set fixed Height for ScrollViewer and the Container (Note: Height of container should be greater than ScrollViewer's Height)
See the below Code
<ScrollViewer Height="500">
<Grid Name="Container" Height="700">
<TextBox/>
<TextBox/>
<TextBox/>
</Grid>
</ScrollViewer>
Now you can scroll the container Grid Even the KeyBoard shown or even focus on a TextBox.

WP7 ListBox Scrolling Not Working

I have the following XAML markup in a WP7 UserControl. My problem is that when my ListBox has more items than will fit on a page it will not scroll properly. I can scroll the list by panning upwards with my finger but as soon as I remove my finger it jumps back to the top of the list (if the list is very long then the scrolling will not even work to this limited extent).
I have tried numerous different layouts with no success e.g. Wrapping ListBox in ScrollViewer, utilising StackPanel instead of Grid, removing the WrapPanel and replacing it with a grid.
Other similar questions suggested removing StackPanel (which I did but made no difference) or using ScrollViewer (which did not work).
The Page that hosts the UserControl uses a GestureListener - I removed that and it still made no difference.

Specify ListBox.Height - something like Height="200". As it is now, ListBox expands automatically to accomodate all loaded items and it grows out of the screen. As a result you get large page with no scroller.
When you add ListBox.Height, the ListBox area won't grow. Instead ListBox ScrollViewer will be activated and you'll get the effect you need.
I use databinding when the ListBox's Height changed depending on the other controls on the page.
<StackPanel x:Name="ContentPanel" Grid.Row="1">
<ListBox x:Name="LstSample" Height="{Binding ElementName=ContentPanel, Path=ActualHeight}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Image Source="{Binding ImagePath}" Stretch="None"/>
<StackPanel Orientation="Vertical">
<TextBlock Text="{Binding Name}" FontSize="45"/>
<TextBlock Text="{Binding Group}" FontSize="25"/>
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
