I need to binding objects of the lists below in a ItemsControl binded in a ScrollViewer in wpf .
I Provand assigning a path but I still can not binding, maybe I'm wrong ? In the subject of the first level the bind is successful , but when I go down in the lists below of the same object bind will not work.
Xaml Scrollviewer:
<surface:SurfaceScrollViewer Grid.Row="2" VerticalScrollBarVisibility="Hidden" Background="#fff" PanningMode="VerticalOnly">
<ItemsControl x:Name="scrollViewerFolderItemsSource" ItemsSource="{Binding Path=companies}">
<ItemsControl.ItemTemplate>

<StackPanel>
<surface:SurfaceButton Tag="{Binding CPID}" Click="Open_Click" Grid.ColumnSpan="2">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border BorderThickness="0,1,0,0" BorderBrush="Gray" Height="57" Background="White">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="80"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0" Background="#fff"></Grid>
<Image Grid.Row="0" Grid.Column="0" Width="32" VerticalAlignment="Center" HorizontalAlignment="Center" Source="{Binding ImageFolder}"></Image>
<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding CompanyName}" Foreground="#565656" FontFamily="{StaticResource Lato Semibold}" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="10" Margin="10,3,0,0" Style="{DynamicResource Lato-Semibold}"/>

<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding AttachmentFolders.Name}" Foreground="#565656" FontFamily="{StaticResource Lato Semibold}" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="10" Margin="10,3,0,0" Style="{DynamicResource Lato-Semibold}"/>
</Grid>
</Border>
</ControlTemplate>
</Button.Template>
</surface:SurfaceButton>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</surface:SurfaceScrollViewer>
CodeBehind view list binded:
My target is binding Text="{Binding companies.Attachment.Name}"
If i print Text="{Binding Attachment}" my result print on deploy is "(Collection)", why print Attachment.Name ?
Attachments is a Collection, to visualize a collection you should use a ListBox and use this binding ItemsSource="{Binding companies.Attachment}", you also need to define the ItemTemplate for the ListBox.
With the ListBox you are able to visualize all the element, but if you want to show just the first attachment name you can use this binding Text="{Binding companies.Attachment[0].Name}"
or another solution could be to create a new property called AttachmentToShow of type Attachment and use this binding
Text="{Binding AttachmentToShow.Name}"
with this solution updating AttachmentToShow will result on an UI update.

</ListView>
I add data to the ListView viewTicket, but depending of a property I would like to change the ItemSource Binding of the ListView viewTicketIngs. In other words, is there anyway that I can use an if expression on the binding? Something like ItemsSource="{Binding IF(mode == 0) {ingredients} else {plates}}"
Change the Binding by a DataTrigger in a Style:
<ListView ...>
<ListView.Style>
<Style TargetType="ListView">
<Setter Property="ItemsSource" Value="{Binding plates}"/>
<Style.Triggers>
<DataTrigger Binding="{Binding mode}" Value="0">
<Setter Property="ItemsSource" Value="{Binding ingredients}"/>
</DataTrigger>
</Style.Triggers>
</Style>
</ListView.Style>
</ListView>
As I understand it, you sometimes dispaly plates, sometimes ingredients. Now there are triggers conditional display. WPF actually has a pretty wide support.
However what might be better is to have 2 different ViewModel classes and two (how I call them) "type targetting data tempaltes". Say you have these clases:
abstract class ViewModelItem { }
class Plate : ViewModelItem { }
class IngredientsList : ViewModelItem { }
The propety you exposie this in, would be set to ViewModelItem. In realtiy you would assign either a Plate or IngredientsList Instance.
Now you define two DataTemplates. A interesting thing about WPF is that if you do not specify a explicit Template, the Code will go out of it's way to try to find one. And it will do the matching via the DataType property of the Template (TargetType for Styles and similar). It works similar to what CSS does, with somebodies code going out of it's way to find a template to apply.
I am currently developing an application for Windows Embedded Handheld 8.1 and have run into an issue where I have a dynamically expanding grid inside a gridview. My problem is that since this application runs on handheld devices I have a very limited space to use on every row.
What I would like to do is to just show general information on each row and then when a row is tapped or selected in the device, I would like to somehow expand that specific row and show some more detailed information, this seems to be problematic however since as soon as I start messing with a specific rows height, every other row in the ItemTemplate naturally also grows, leaving a lot of blank spaces in the grid.
Normally I would have used a DataGrid and DataGrid.RowDetailsTemplate, but that control does not seem to be implemented in WEH8.1.
So my question is if someone has a solution or possibly a workaround to my problem?

I am having problem styling the full mode of listpicker. I want it should fully cover the page but I see a margin from the left and up in full mode.
<toolkit:ListPicker Header="SELECT TRANSLATION" x:Name="lspTranslationLang"
SelectedItem="{Binding Name, Mode=TwoWay}" SelectionChanged="lspTranslationLang_SelectionChanged">
<toolkit:ListPicker.HeaderTemplate>
<DataTemplate>
<StackPanel>
<TextBlock FontWeight="Bold" Foreground="Black" Text="Select Translation"></TextBlock>
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.HeaderTemplate>
<toolkit:ListPicker.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock FontSize="30" Text="{Binding Language}" />
</StackPanel>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate>
Grid Margin="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Image Grid.Row="0" Margin="10,0,0,0" Width="30" Height="30" Grid.Column="0" Source="{Binding ImagePath}" ></Image>
<TextBlock Grid.Row="0" Padding="10,0,10,0" Grid.Column="1" Text="{Binding Language}" FontSize="30"/>
<TextBlock Grid.Row="1" Padding="10,0,10,0" Grid.Column="1" Text="{Binding Description}" FontSize="30"/>
<Line X1="0" X2="480" Y1="0" Y2="0" Grid.Row="1" Grid.ColumnSpan="2" VerticalAlignment="Bottom" StrokeThickness="1" Stroke="LightGray" />
</Grid>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>
How I can change the style for full mode of listpicker?
Check out this tutorial for customizing list picker from geekchamp.
Customizing list picker
Change the data template of the full mode property. And set the margins using expression blend. It is a good editor in customizing.
You must probably add the following property
ExpansionMode="FullScreenOnly"
I read many tutorials from MSDN about WPF styling and datatemplating and contenttemplating but no success.
I need to make same TabItems in my TabControl and I made manually TabItem which i want to use as host for Style and ContentTemplate for other TabItems in TabControl
<TabItem Header="1.semestar">
<Grid x:Name="GridSemestra">
<Grid.DataContext>
<ViewModel:PredmetVM/>
</Grid.DataContext>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="100"/>
<ColumnDefinition MinWidth="30"/>
</Grid.ColumnDefinitions>
<Grid.Children>
<ListBox x:Name="PredmetiLW" Grid.Row="0" BorderThickness="0" Grid.Column="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Naziv}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListBox x:Name="RadioLW" Grid.Row="0" Grid.Column="1" BorderThickness="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Ocjena}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Label Content="Prosjek Semestra :" HorizontalAlignment="Right" VerticalAlignment="Center" Grid.Row="1" Grid.Column="0" />
<Label x:Name="_prosjekSemestra" Grid.Row="1" Grid.Column="1" ContentStringFormat="F2" Content="{Binding _prosjek, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Label Content="Ostvareni ECTS-ovi :" HorizontalAlignment="right" VerticalAlignment="Center" Grid.Row="2" Grid.Column="0" />
<Label x:Name="_ectsSemestra" Grid.Row="2" Grid.Column="1" Content="{Binding _ectsovi, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid.Children>
</Grid>
</TabItem>
This is how you define a style for any TabItem. In the example I created a white border and a black background for the Header content of the TabItem:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Border BorderBrush="White" BorderThickness="5" Margin="2">
<Grid Width="100" Height="100" Background="Black">
<ContentPresenter x:Name="ContentSite"
VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header"
RecognizesAccessKey="True"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
If you want your items to render with same template set the ItemTemplate for your TabControl like below:
<TabControl ItemsSource="{Binding MyTabItems}">
<TabControl.ItemTemplate>
<DataTemplate>
<Grid x:Name="GridSemestra">
<Grid.DataContext>
<ViewModel:PredmetVM/>
</Grid.DataContext>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MinWidth="100"/>
<ColumnDefinition MinWidth="30"/>
</Grid.ColumnDefinitions>
<Grid.Children>
<ListBox x:Name="PredmetiLW" Grid.Row="0" BorderThickness="0" Grid.Column="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Naziv}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListBox x:Name="RadioLW" Grid.Row="0" Grid.Column="1" BorderThickness="0" ItemsSource="{Binding Predmeti}" HorizontalAlignment="Center" VerticalAlignment="Center" >
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Ocjena}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Label Content="Prosjek Semestra :" HorizontalAlignment="Right" VerticalAlignment="Center" Grid.Row="1" Grid.Column="0" />
<Label x:Name="_prosjekSemestra" Grid.Row="1" Grid.Column="1" ContentStringFormat="F2" Content="{Binding _prosjek, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center" />
<Label Content="Ostvareni ECTS-ovi :" HorizontalAlignment="right" VerticalAlignment="Center" Grid.Row="2" Grid.Column="0" />
<Label x:Name="_ectsSemestra" Grid.Row="2" Grid.Column="1" Content="{Binding _ectsovi, Mode=OneWay}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid.Children>
</Grid>
</DataTemplate>
</TabControl.ItemTemplate>
</TabControl>
Doing this, for all the items in property MyTabItems, TabItems will be generated
//this is usercontrol code
<ListBox Name="OvernightAverageListBox" ItemsSource="{Binding Path=OvernightAverageCollections}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Name="items" Background="{Binding BackColor}" Height="200" Width="200">
<TextBlock Height="46" HorizontalAlignment="Left" Margin="26,10,0,0" Name="currentRate" Text="{Binding Current_rate}" VerticalAlignment="Top" FontSize="36" />
<TextBlock Height="22" HorizontalAlignment="Left" Margin="26,20,0,0" Name="rate_difference" Text="{Binding RateChange_Value}" VerticalAlignment="Top" FontSize="20" />
<TextBlock Height="30" HorizontalAlignment="Left" Margin="26,30,0,0" Name="productName" Text="{Binding Product_name}" VerticalAlignment="Top" FontSize="24" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
//this is binding code on view
<controls:PanoramaItem Header="Overnight Average" Tap="RateTile_Tap">
<Grid x:Name="overnightAverage">
<views:OvernightAverageTileControl x:Name="eventsView"> </views:OvernightAverageTileControl>
</Grid>
</controls:PanoramaItem>
</ListBox>
now acoording to my code the tiles are coming vertically means each tile is taking in one row.
but i want them to come both horizontally and vertically means two tiles in each row.
plz share ur suggetion i am new to xaml designing.
first image shows wat i am getting.
second image is wat i want.
thanks :)
You could replace the StackPanel in your DataTemplate by a Grid:
<DataTemplate>
<Grid Name="items" Background="{Binding BackColor}" Height="200" Width="200">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Grid.Row="0" Text="{Binding Current_rate}" ... />
<TextBlock Grid.Column="1" Grid.Row="0" Text="{Binding RateChange_Value}" ... />
<TextBlock Grid.Column="0" Grid.Row="1" Text="{Binding Product_name}" ... />
</Grid>
</DataTemplate>
You may also specify absolute or relative widths of the columns and heights of the rows by setting the ColumnDefinition.Width and the RowDefinition.Height properties.
I have done it successfully using WrapPanel in toolkit oct 2011.
