in win phone when having two Grids one after another and each has it's own listBox the scrolling is not working.
Any ideas ?
<Grid x:Name="LayoutRoot"
Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<!--ContentPanel - place additional content here-->
<Grid x:Name="ContentPanel1" Grid.Row="1" Margin="12,0,12,0">
<ListBox x:Name="lstData1"
ItemsSource="{Binding Source={StaticResource productCollection}, Path=DataCollection}">
<ListBox.ItemTemplate>
<DataTemplate>
.................
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
<Grid x:Name="ContentPanel2" Grid.Row="2" Margin="12,0,12,0">
<ListBox x:Name="lstData2"
ItemsSource="{Binding Source={StaticResource productCollection}, Path=DataCollection}">
<ListBox.ItemTemplate>
<DataTemplate>
..................
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</Grid>
Thank you
Best Regards
Height must be specified for the scroll to work

I was tying to set focus on a TextBox used to build a customized "Numeric Up Down" control.
This is the custom "Numeric Up Down"
<Style x:Key="SpinButton" TargetType="Slider" >
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Slider">
<Border Grid.RowSpan="3" BorderThickness="1,1,1,1" BorderBrush="WhiteSmoke">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height=".5*"/>
<RowDefinition Height=".5*"/>
</Grid.RowDefinitions>
<TextBox Name="textBoxNumericUpDown" Grid.RowSpan="3" Margin="2,0,0,0" Text="{Binding Value,Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" FontSize="20" VerticalAlignment="Center" Background=" {x:Null}" Foreground="White" BorderThickness="0" CaretBrush="White" IsTabStop="True"/>
<RepeatButton Grid.Column="1" Grid.Row="0" Margin="0,0,-5,0" Command="Slider.IncreaseLarge" Style="{StaticResource TimeRepeatButtonStyle}" Content="+" Background="{x:Null}" BorderBrush="White" Foreground="White" FontSize="18" Cursor="Hand" Width="44" Height="44" IsTabStop="False"/>
<RepeatButton Grid.Column="1" Grid.Row="1" Command="Slider.DecreaseLarge" Margin="0,1,-5,0" Style="{StaticResource TimeRepeatButtonStyle}" Content="-" Background="{x:Null}" BorderBrush="White" Foreground="White" FontSize="18" Cursor="Hand" Width="44" Height="44" IsTabStop="False"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Usage
<Slider PreviewTextInput="textBoxTimeMinute_PreviewTextInput" Name="textBoxTimeMinute" Width="100" Style="{StaticResource SpinButton}" Maximum="999" Margin="8" HorizontalAlignment="Left" Minimum="0" IsTabStop="True" TabIndex="0"/>
<Label Grid.Column="1" Content=":" VerticalAlignment="Center" IsTabStop="False"/>
<Slider PreviewTextInput="textBoxTimeSecond_PreviewTextInput" Grid.Column="2" Name="textBoxTimeSecond" Width="100" Style="{StaticResource SpinButton}" Maximum="60" Margin="8" HorizontalAlignment="Left" Minimum="-1" IsTabStop="True" TabIndex="1"/>
Wanted result (Automatic focus on the first textbox if no number inside)
Wanted result (Automatic focus on the first textbox if number inside, number is selected)
I tried different ways to make it select the correct Control, but it always selects the outer layer. In my case The Grid/Border.
Only after I press TAB I can have it select the correct TextBox Control.
Is there any way in WPF I can achieve the focus on textbox without pressing TAB?
Solved:
If you want to focus a TextBox inside a ControlTemplate you have to set up a trigger on the "IsFocused" property.
When it becomes true then you have to set the FocusManager.FocusedElement field to the name of the TextBox (or other control) you want to focus.
Below is the code I used to achieve this:
<ControlTemplate TargetType="Slider">
<TextBox x:Name="TextBoxToFocus"/> //The textbox(or any other element) I want to set focus to. It is very important to have it named, otherwise I won't know which control to focus.
<ControlTemplate.Triggers> //The trigger
<Trigger Property = "IsFocused" Value = "True" /> //The property the trigger is watching
<Setter TargetName="TextBoxToFocus" Property="FocusManager.FocusedElement" Value="{Binding ElementName=NumericUpDown}"/> //Setter when the trigger executes
</Trigger>
</ControlTelmplate.Triggers>
I have a LongListSelector and I want to add a Flick gesture to it. I want to mimic iOS swipe to delete action.
I only managed to add the Flick event to the whole LongListSelector, but I couldn't get the item the event happend on.
UPDATE
Here's how I managed to do it in case anyone needs it:
<phone:PhoneApplicationPage.Resources>
<DataTemplate x:Key="dataTemplate" >
<Grid x:Name="Main" Margin="0,0,0,5" VerticalAlignment="Center" Tag="{Binding}">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<toolkit:GestureService.GestureListener>
<toolkit:GestureListener Flick="GestureListener_Flick"/>
</toolkit:GestureService.GestureListener>
<StackPanel Orientation="Horizontal" Grid.Column="0" VerticalAlignment="Center" HorizontalAlignment="Stretch">
<StackPanel Orientation="Horizontal" VerticalAlignment="Center" Margin="0,0,0,0">
<StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Center">
<TextBlock Text="{Binding name}" TextTrimming="WordEllipsis" Style="{StaticResource PhoneTextNormalStyle}" FontSize="28" HorizontalAlignment="Stretch"/>
<TextBlock Text="{Binding description}" MaxWidth="420" TextWrapping="Wrap" Margin="12,0" Style="{StaticResource PhoneTextSubtleStyle}" HorizontalAlignment="Stretch"/>
</StackPanel>
</StackPanel>
</StackPanel>
<StackPanel Grid.Column="1" x:Name="LeftPanel" Orientation="Horizontal" HorizontalAlignment="Right">
<Button Name="deleteBtn" Visibility="{Binding showDelete, Converter={StaticResource VisibilityConverter}}" Content="Delete" HorizontalAlignment="Right" VerticalAlignment="Center"/>
</StackPanel>
</Grid>
</DataTemplate>
</phone:PhoneApplicationPage.Resources>
<toolkit:LongListSelector Grid.Row="0" HorizontalAlignment="Stretch" x:Name="data" Background="Transparent"
GroupHeaderTemplate="{StaticResource groupHeader}"
GroupItemTemplate="{StaticResource itemHeader}"
ItemTemplate="{StaticResource meetingItemTemplate}">
</toolkit:LongListSelector>
and in the code you bind your LongListSelector to whatever you want.
I have a listbox with for data templates, and I want to disable the tilt effect on one of the data templates, but it is not working... this is what I've been trying:
<ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled" x:Name="MainListBox" Margin="0,10,0,0" SelectionChanged="MainListBoxSelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<local:Datatemplates Content="{Binding}">
<local:Datatemplates.ThirdItem>
<DataTemplate>
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="0,10" >
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="1" toolkit:TiltEffect.SuppressTilt="True">
<TextBlock Text="{Binding Title}" TextWrapping="NoWrap" FontSize="{StaticResource PhoneFontSizeExtraLarge}" Style="{StaticResource PhoneTextGroupHeaderStyle}" toolkit:TiltEffect.SuppressTilt="True"/>
<TextBlock Text="{Binding SubTitle1}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSmallStyle}" toolkit:TiltEffect.SuppressTilt="True"/>
<TextBlock Text="{Binding SubTitle2}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSmallStyle}" toolkit:TiltEffect.SuppressTilt="True"/>
</StackPanel>
</Grid>
</DataTemplate>
</local:Datatemplates.ThirdItem>
</local:ProfileSetupDatatemplates>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I already tried to put the suppress tilt effect everywhere it wasn't working.
What am I missing
TiltEffect is only applied to button controls (Button, CheckBox, etc.) and ListBoxItems, so trying to suppress it on a Stackpanel won't work.
So:
you should be able to tweak your template like so:
<DataTemplate>
<ListBoxItem toolkit:TiltEffect.SuppressTilt="True" >
...your code
</ListBoxItem>
</DataTemplate>
I have a listbox bound to a view model property called Choices. Each choice has a label and an index. I need to bind the buttons in the list to a command on the same view model. So far Ive figured out this much:
<ListBox Grid.Row="1" ItemsSource="{Binding Choices}" SelectedIndex="{Binding SelectedChoice, Mode=TwoWay}" >
<ListBox.ItemTemplate>
<DataTemplate>
<Grid HorizontalAlignment="Stretch" Margin="1">
<Button Content="{Binding Caption}" Height="24" HorizontalAlignment="Stretch"
Command="{Binding RelativeSource={RelativeSource ???},
Path=SelectChoice}" CommandParameter="{Binding}"/>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
I cant figure out what RelativeSource to use for the command and I'm not sure the CommandParameter is correct.
This seems a really simple thing to do but it's obviously too simple for my poor old brain. Can anyone help please?
Thanks
Sorted:
<ItemsControl Grid.Row="1" ItemsSource="{Binding Choices}" >
<ItemsControl.ItemsPanel >
<ItemsPanelTemplate >
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center">
</StackPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Caption}" Height="24" HorizontalAlignment="Stretch" Margin="0,0,4,0"
Command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ItemsControl}}, Path=DataContext.SelectChoice}"
CommandParameter="{Binding}"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
I have a ListBox so I can use bindings. I'm new to Silverlight so maybe there is another way. I just want to display a list of items in a template. I don't need it to be scollable, because it fits the screen. Here is ma code :
<ListBox Margin="0,0,-12,0" ItemsSource="{Binding NewSearchItems}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="0,0,0,0" Width="440">
<TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextTitle2Style}"/>
<TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Style="{StaticResource PhoneTextAccentStyle}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Thanks,
In XAML:
<ListBox ScrollViewer.VerticalScrollBarVisibility="Disabled" />
