I am using autocompletebox toolkit from windowsphone7.5 version. It works well in wp7.1 toolkit.
If I use autocompletion with inner control margin it's not worked properly, it shows the result on the top,
Here I attached the autocompletion error screenshot.
This is the code :
<Grid Grid.Row="1" Height="76" VerticalAlignment="Top">
<toolkit:AutoCompleteBox VerticalAlignment="Bottom" Width="400" ValueMemberBinding="{Binding Title}" HorizontalAlignment="Left" Grid.Row="0" x:Name="acBox" Margin="10,0,10,0" ItemsSource="{Binding CategoryListitems}">
<toolkit:AutoCompleteBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Title}"/>
</DataTemplate>
</toolkit:AutoCompleteBox.ItemTemplate>
</toolkit:AutoCompleteBox>
</Grid>

In my mobile application, there's declared a list with images:
<ListView ItemsSource="{Binding PhotosCollection}"
SelectionMode="Single"
VerticalOptions="FillAndExpand"
SelectedItem="{Binding SelectedPhotoDocument}">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Margin="4">
<Grid.RowDefinitions>
<RowDefinition Height="64" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Grid.RowSpan="2"
Grid.Column="0"
Source="{Binding ThumbnailImageSource}"
HorizontalOptions="Start"
VerticalOptions="Center"
Aspect="AspectFit" />
<Label Grid.Column="1"
Grid.RowSpan="2"
Text="{Binding Description}"
FontAttributes="Bold"
HorizontalOptions="Start"
VerticalOptions="Center"
HorizontalTextAlignment="Start"
VerticalTextAlignment="Center" />
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
This list works perfectly on Android platform and displays images along with descriptions. But on iOS platform thumbnails are not being displayed. Only descriptions are shown.
How can I overcome this issue?
To fix this issue to get mobile app working as well as on iOS and on Android, I used ImageCell instead of Image and Label tags in the ListView data template declaration.
<ListView
ItemsSource="{Binding PhotosCollection}"
SelectionMode="Single"
VerticalOptions="FillAndExpand"
SelectedItem="{Binding SelectedPhotoDocument}">
<ListView.ItemTemplate>
<DataTemplate>
<ImageCell
ImageSource="{Binding ThumbnailImageSource}"
Text="{Binding Description}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
I have a basic Microsoft.UI.Xaml.Controls.Grid with a text field and a button in it.
XAML:
<Grid Margin="16"
CornerRadius="12"
Background="{StaticResource Color08Brush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBox Grid.Column="0"
PlaceholderText="Write a message…"
Margin="12,12,4,12"
MaxHeight="92"
TextWrapping="Wrap"
Text="{Binding [Input], Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Style="{StaticResource ChatTextBoxStyle}" />
<Button Grid.Column="1"
Command="{Binding [SendMessage]}"
Style="{StaticResource EllipseButtonStyle}"
Background="{StaticResource Color11Brush}"
Width="44"
Height="44"
Margin="0,0,12,0"
IsTabStop="False">
<u:PathControl Style="{StaticResource ForwardArrowPathStyle}"
Width="8" />
</Button>
</Grid>
Everything works in Android. Having issues in iOS. When in the TextBox, the iOS keyboard opens as expected. You type some text and hit the Button to send the message. However, this merely dismisses the iOS keyboard and doesn't fire SendMessage
Tried using ios:VisualElement.CanBecomeFirstResponder="True" but same result on button click with keyboard open in iOS.
Thanks for any help!
I'm new with xamarin and I'm trying to use a searchbar with a result listview (which is hidden) on top of a main listview (ie: mobile facebook friend search)
On iOS I'm not being able to tap on the main listview because the result listview is always on top of the other one even if it's not visible.
Here is the code:
<AbsoluteLayout>
<StackLayout Orientation="Vertical" Padding="0,50,0,0">
<StackLayout Padding="20,0,0,10">
<Label Text="{Binding SelectedAddressString, StringFormat='BCLs near {0}'}" />
</StackLayout>
<ListView x:Name="iOSlstBCLs" ItemsSource="{Binding BCLList}" IsPullToRefreshEnabled="true" RefreshCommand="{Binding RefreshCommand}" IsRefreshing="{Binding IsRefreshing, Mode=OneWay}">
<ListView.ItemTemplate>
<DataTemplate>
<TextCell Text="{Binding Name}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
<StackLayout Orientation="Vertical" HorizontalOptions="StartAndExpand" VerticalOptions="Fill" AbsoluteLayout.LayoutFlags="WidthProportional" AbsoluteLayout.LayoutBounds="0,0,1,1">
<SearchBar Text="{Binding SearchText, Mode=TwoWay}" Placeholder="Search" AbsoluteLayout.LayoutFlags="WidthProportional" AbsoluteLayout.LayoutBounds="0,0,1,1" />
<ListView IsVisible="{Binding IsSuggestionListVisible, Mode=OneWay}" ItemsSource="{Binding SuggestionList}" SelectedItem="{Binding SelectedAddress}" VerticalOptions="Fill" AbsoluteLayout.LayoutFlags="WidthProportional" AbsoluteLayout.LayoutBounds="0,0,AutoSize,AutoSize" BackgroundColor="White">
<ListView.ItemTemplate>
<DataTemplate>
<TextCell Text="{Binding formatted_address}" />
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</AbsoluteLayout>
Any ideas?
From my experience, you should never use an Absolute Layout if at all possible. It seems like it would be better to use a Stack and place both of your other stacks within that. Then set the visibility as needed. I am not positive, but I am guessing that the Absolute Layout is messing you up.
Does Windows Phone 7 have anything like iPhone's UITableView?
[Basically, I'm porting an iOS app where the table views worked really well.]
you can create something similar to Table view using the below XAML Code.
<ListBox >
<ListBoxItem>
<StackPanel Orientation="Horizontal" >
<Border BorderThickness="3" BorderBrush="#A5FFFFFF" Width="80" Margin="0,20,0,20" Height="60">
<Image Source="{Binding ImageUrl, Mode=OneWay}" VerticalAlignment="Stretch" Margin="0,0,0,0" Width="80" Height="60" Stretch="Fill" />
</Border>
<TextBlock TextWrapping="Wrap" Text="Foobar" FontSize="40" FontWeight="Normal" VerticalAlignment="Center" Margin="30,0,0,0" />
</StackPanel>
</ListBoxItem>
<ListBoxItem>
<StackPanel Orientation="Horizontal" >
<Border BorderThickness="3" BorderBrush="#A5FFFFFF" Width="80" Margin="0,20,0,20" Height="60">
<Image Source="{Binding ImageUrl, Mode=OneWay}" VerticalAlignment="Stretch" Margin="0,0,0,0" Width="80" Height="60" Stretch="Fill" />
</Border>
<TextBlock TextWrapping="Wrap" Text="Foobar" FontSize="40" FontWeight="Normal" VerticalAlignment="Center" Margin="30,0,0,0" />
</StackPanel>
</ListBoxItem>
</ListBox>
The above example will create a table view with two elements .If you want you can Add Border to seperate between each table.
Hope it helps.
I imagine that the closest match is the Grid control, which enables you to define rows and columns and add content to grid cells. You might find the MSDN page How to: Create a Grid Element helpful.
I am trying to get the Items in a ListBox to span the entire width of the ListBox. I have found several posts dealing with HorizontalContentAlignment="Stretch" but I have not been able to get it to work in my WP7 app. Here is my ListBox:
<ListBox Margin="8" HorizontalContentAlignment="Stretch" ItemsSource="{Binding Collection}" >
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" CornerRadius="3" Background="#FFE88D34"
BorderThickness="1" HorizontalAlignment="Stretch" >
<Grid Background="Transparent" HorizontalAlignment="Stretch" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock
Grid.Column="0" HorizontalAlignment="Stretch"
Margin="2"
FontSize="10"
Text="{Binding Property1}"/>
</Grid>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
I am trying to get the orange Border to span the entire width of the listbox so that all the list items are the same size and not just the size of the text in the TextBlock.
Use the following static resource as ItemContainerStyle of Listbox:
ItemContainerStyle="{StaticResource ListboxStretchStyle}"
<Application.Resources>
<Style TargetType="ListBoxItem" x:Key="ListboxStretchStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<ContentPresenter HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Application.Resources>
This is what I do use for that:
<ListBox Height="430" Margin="50,70,50,110" Name="myListBox" >
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<ContentPresenter
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
<ListBox.ItemTemplate>
<DataTemplate>
<Border Background="{StaticResource PhoneAccentBrush}" >
<TextBlock
Text="{Binding Text}"
FontSize="30"
Foreground="{StaticResource PhoneForegroundBrush}" />
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

I believe this is a bug in the beta release, because HorizontalContentAlignment should be it.
as a workaround you might have to use a fixed width value.
Looks like John Gardner is on point with this being a bit of a defect in the Beta. It works fine in "plain old" Silverlight, but yields oddly-centered areas in the Phone. It is easy enough to work past, however.
Get rid of / comment out the ListBox.ItemContainerStyle entry in your listbox, above.
In Blend, select your ListBox in the Objects and Timeline panel, right click, and select Edit Additional Templates / Edit Generated Item Container (ItemContainerStyle) / Edit a Copy... Choose a name/key and location for the new style resource.
Locate the ContentContainer control, and set its Horizontal Content Alignment to Bind to the Horizontal Content Alignment set in the item consuming this template, (HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" ) as follows:
<ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
Once you've told the ContentControl how it should align its (ahem) content, the results should be what you expected.
