I have this DataTemplate in my ListBox:
<local:SearchTemplateSelector.VideoTemplate>
<DataTemplate>
<Grid>
<Rectangle Height="1" HorizontalAlignment="Stretch" VerticalAlignment="Top" Fill="Black" Opacity="0.3" />
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Margin="0" HorizontalAlignment="Left" Source="{Binding Path=ImgUrl}" Width="100" Height="100" />
<Grid Grid.Column="1" Margin="10,0,8,0">
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Text="{Binding Name}" FontSize="20" Foreground="Black" TextWrapping="Wrap" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" />
<StackPanel Orientation="Horizontal" Margin="0,-5,0,0" Grid.Row="1">
<TextBlock Text="Views: " FontSize="20" Foreground="Black"/>
<TextBlock Text="{Binding ViewCount}" FontSize="20" Foreground="Black"/>
</StackPanel>
<TextBlock Text="{Binding TimeStr}" FontSize="20" Foreground="Black" Grid.Row="2" Margin="0,0,0,0" />
</Grid>
</Grid>
</Grid>
</DataTemplate>
</local:SearchTemplateSelector.VideoTemplate>
Now i have Image that i binding from ImgUrl of my object.And i want to know if there is possibility to make something like this:
If the image is in the device take it from the device,if not download it and save it on the device for next time, every image have a unique id so i can just save it with id.png
If I understand you correct, you have to add logic to ImgUrl property. You have to add some method in Set{}, which will try load image from isolatedStorage, and catch exception, in which it will use method to load and save image to isolatedStorage.

I'm new to WPF app developing and there is no such thing as RelativeLayout(Where I can arrange views relative to another view...like in Android).
My listview row Template looks like this.
Can someone help me with the code to design such template in XAML
EDIT : This is the code I've tried so far(Only for the first row i.e for name, time and date)...It doesn't seem to work.
<ListView x:Name="listView" Grid.ColumnSpan="2" HorizontalAlignment="Left" Height="752" Margin="20,282,0,0" VerticalAlignment="Top" Width="486" >
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="5*"/>
<ColumnDefinition Width="5*"/>
<!--<ColumnDefinition Width="120"/>-->
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="{Binding Name}" FontWeight="Bold" />
<TextBlock Grid.Row="0" Grid.Column="1" FlowDirection="RightToLeft" Text="{Binding Time}" FontWeight="Bold" />
<!--<TextBlock Grid.Column="1" Background="Gainsboro" FlowDirection="LeftToRight" Text="{Binding Date}" TextDecorations="Underline" Foreground="Blue" Cursor="Hand" />-->
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The Time and Date appear beside each other. I thought using flow direction should help.
Try this :
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="{Binding Name}" FontWeight="Bold" />
<TextBlock Grid.Row="0" Grid.Column="1" Text="{Binding Time}" FontWeight="Bold" HorizontalAlignment="Right"/>
<TextBlock Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Text="{Binding Header}" FontWeight="Bold" />
<TextBlock Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2" Text="{Binding Details}" FontWeight="Bold" />
</Grid>
</DataTemplate>
NOTE: Avoid some syntax error because I developed in notepad. It is not having any scrollbar as shown in image in your question. You can comment if any issue. You can apply text formatting and margin as per need.
I have just started learning windows app development. Like what do we call it (A dialog box, Contentdialogbox, Message Dialog)? Thanks in advance.
Okay I tried this since I have my data in a datatemplate inside a contentpresenter(Making a master detail view) now when user clicks on a icon the popup should open and also display the data related to that event selected inside that list.How do I achieve this since the popup dialog control is defined inside a datatemplate so in my cs file it does not recognize the control so I am not able to open the popup dialog.
Xaml Code:
<DataTemplate x:Key="DetailContentTemplate" x:DataType="data:Event">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="200" />
<RowDefinition Height="50" />
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid x:Name="Section2" Grid.Row="0">
<Grid.Background>
<ImageBrush ImageSource="ms-appx:///Assets/8.JPG" Stretch="Fill" />
</Grid.Background>
<TextBlock MaxWidth="250"

FontFamily="Baskerville Old Face"
FontSize="30"
Foreground="{ThemeResource ToggleButtonPressedForegroundThemeBrush}"
TextWrapping="WrapWholeWords"
d:LayoutOverrides="Width, LeftPosition, RightPosition, TopPosition, BottomPosition">
<Run Text="Gravitas Premier League" />
</TextBlock>
</Grid>
<Grid x:Name="Content"
Grid.Row="1"
Margin="0,10,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0">
<RelativePanel>
<SymbolIcon x:Name="symbol"

</RelativePanel>
</StackPanel>
<StackPanel Grid.Column="1" HorizontalAlignment="Center">
<RelativePanel>
<SymbolIcon x:Name="symboll"

RelativePanel.AlignLeftWithPanel="True"
Symbol="People" />
<TextBlock HorizontalAlignment="Right"
VerticalAlignment="Top"
RelativePanel.RightOf="symboll"

</RelativePanel>
</StackPanel>
<StackPanel Grid.Column="2" HorizontalAlignment="Right">

</RelativePanel>
</StackPanel>
</Grid>
<TextBlock Grid.Row="2"
HorizontalAlignment="Center"

Text="{x:Bind description}"
TextWrapping="WrapWholeWords" />
<Grid Grid.Row="3">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<SymbolIcon Grid.Column="0"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Symbol="Phone" />
<SymbolIcon Grid.Column="1"
x:Name="People"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Symbol="People"
IsTapEnabled="True"
Tapped="ShowPopupOffsetClicked"
/>
<SymbolIcon Grid.Column="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Symbol="Mail" />
</Grid>
</Grid>
</DataTemplate>
Now how do I open up the popup when the user taps the symbol with the name People and with necessary bindings of data with a observablecollection say EventList.
There are a lot of ways to implement the UI like in your screenshot. As you've added template10 in your question, I suppose you are using Template10 in your project. And in Template10, we can use ModalDialog to implement this. Here I use a Minimal Template 10 project for example.
Firstly, we may need to change ModalBackground to make the background color looks like what in your screenshot. As the ModalDialog we used here is the root frame created by Bootstrapper automatically, so we need override CreateRootElement in App.xaml.cs like:
public override UIElement CreateRootElement(IActivatedEventArgs e)
{
var b = Current;
var frame = new Windows.UI.Xaml.Controls.Frame();
var nav = b.NavigationServiceFactory(BackButton.Attach, ExistingContent.Include, frame);
//change background
var background = new Windows.UI.Xaml.Media.SolidColorBrush(Windows.UI.Colors.Gray);
background.Opacity = 0.2;
return new Template10.Controls.ModalDialog
{
ModalBackground = background,
DisableBackButtonWhenModal = true,
Content = nav.Frame
};
}
Then we can edit Busy.xaml to implement the panel in your screenshot. In Busy.xaml, it's a UserControl used as the ModalContent of ModalDialog. For example,
<UserControl x:Class="T10Minimal.Views.Busy"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="using:T10Minimal.Views"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
d:DesignHeight="300"
d:DesignWidth="400"
mc:Ignorable="d">
<Grid Width="300"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Background="White"
CornerRadius="10">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
...
</Grid.RowDefinitions>
<TextBlock Margin="20,0"
VerticalAlignment="Center"
FontSize="24"
Foreground="Black">
Song Options
</TextBlock>
<Button Margin="12"
HorizontalAlignment="Right"
VerticalAlignment="Top"
Click="CloseClicked"
Foreground="Black"
Style="{StaticResource TextBlockButtonStyle}">
<SymbolIcon Symbol="Clear" />
</Button>
...
</Grid>
</UserControl>
The bindings might like the BusyText in the original control, you can change its type to your binding data's type and also change the SetBusy method. After this, you can call SetBusy method in your ShowPopupOffsetClicked method to open the "popup".
This is just a simple sample, you can refer to it to implement your own. And in the sample, I used the ModalDialog created as the root frame of the application. If you need more than one ModalDialog, you can refer to Search (and Login) Sample on GitHub.
I have a big main grid with several rows and columns. I want to place in one of these cells a vertical stackpanel. In this stackpanel there is a textblock and a scrollviewer. My problem is, that the stackpanel doesn't get limited by the cell, instead the stackpanel gets big enough to fit the whole scrollviewer.
How can I solve this?
EDIT: my xaml code:
<Grid x:Name="Grid1" Margin="120,0,0,0" Width="1244">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="0*"/>
<ColumnDefinition Width="33*"/>
<ColumnDefinition Width="40"/>
<ColumnDefinition Width="50*"/>
<ColumnDefinition Width="40"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="71"/>
<RowDefinition Height="40"/>
<RowDefinition/>
<RowDefinition Height="20"/>
</Grid.RowDefinitions>
<StackPanel Grid.Column="3" Grid.Row="2" Grid.ColumnSpan="2" Margin="0">
<TextBlock TextWrapping="Wrap" FontSize="48" Margin="0" VerticalAlignment="Top" Foreground="#FF0083FF" Text="Top 10:" HorizontalAlignment="Left" FontFamily="Segoe UI Light"/>
<ScrollViewer Margin="0,20,0,0" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Visible">

<StackPanel Orientation="Horizontal">
<StackPanel >
<TextBlock FontSize="32" Text="1" Foreground="#FF0083FF"/>

</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackPanel>
</ScrollViewer>
</StackPanel>
</Grid>
Use another Grid instead of a StackPanel:
<Grid Grid.Column="3" Grid.Row="2" Grid.ColumnSpan="2" Margin="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock FontSize="48" FontFamily="Segoe UI Light"
Foreground="#FF0083FF" HorizontalAlignment="Left"
TextWrapping="Wrap" Text="Top 10:"/>
<ScrollViewer Grid.Row="1" Margin="0,20,0,0"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Visible">
...
</ScrollViewer>
</Grid >
I'm using a ExpanderView to display some data in my app. But I'm having some difficulty trying to find out how to get an ExpanderViewItem's data after it's been selected.
On a ListBox you can call SelectionChanged="yourFunction" in your xaml code.. but for the expanderview I have no idea how to do this?
This is my XAML code for the expander:
<!--Custom header template-->
<DataTemplate x:Key="CustomHeaderTemplate">
<TextBlock Text="" FontSize="28" />
</DataTemplate>
<!--Custom expander template-->
<DataTemplate x:Key="CustomExpanderTemplate">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Rectangle Width="400" Height="60" Fill="#FFF1F1F1" HorizontalAlignment="Stretch" StrokeThickness="0" Grid.Row="0" Grid.Column="0" />
<TextBlock Text="{Binding procedureName}" FontSize="30" Foreground="#FF00457C" FontWeight="Normal" Grid.Row="0" Grid.Column="0" VerticalAlignment="Center" Margin="10,0,0,0" />
</Grid>
</DataTemplate>
<!--Custom expander items template-->

I'd really appreciate any help in the right direction! This seems to be a question that is not easily answered around the web.
#Frederik I've implemented what you've done in the code above using the SelectionChanged event of the ListBox - it still works fine for me.
I've been banging my head against the wall for a bit, but finally managed to solve it. First of all for the ItemTemplate I've made sure that the template is placed in a ListBoxItem element as it follows:
<DataTemplate x:Key="ExpanderViewItems" >
<ListBoxItem DataContext="{Binding}" Tap="ListBoxItem_Tap_1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="15" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto" />
<ColumnDefinition Width="auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="{Binding flagIcon}" Grid.Row="0" Grid.RowSpan="3" Grid.Column="0" />
<TextBlock FontSize="26" Text="{Binding N}" Foreground="Black" FontWeight="Normal" Grid.Row="0" Grid.Column="1"/>
<TextBlock FontSize="20" Text="{Binding RNG}" Foreground="Black" FontWeight="Normal" HorizontalAlignment="Right" Grid.Row="0" Grid.Column="2"/>
<TextBlock FontSize="26" Text="{Binding ValueAndUnit}" Foreground="Black" FontWeight="Medium" HorizontalAlignment="Right" Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="2"/>
<TextBlock FontSize="18" Text="{Binding COM}" Foreground="Black" FontWeight="Normal" Grid.Row="2" Grid.Column="1" Grid.ColumnSpan="2" TextWrapping="Wrap" />
<Line StrokeThickness="1" Stroke="#C4C6CC" Stretch="Fill" X1="0" X2="1" Y1="0" Y2="0" VerticalAlignment="Center" Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="3" />
</Grid>
</ListBoxItem>
</DataTemplate>
Once this is in place, go in the code behind and in the Tap event declared for the ListBoxItem use something like this:
ListBoxItem item = sender as ListBoxItem;
ExpanderItemModel model = item.DataContext as ExpanderItemModel;
Of course, ExpanderItemModel will be whatever you're using for your expander items...
This worked fine for me
Hope this helps!
Good luck!
You can use the "tap" event on the listbox:
In your XAML file add a tap event listner:
<!--Listbox Containing ExpanderViews-->
<ListBox Name="testsList" Grid.Row="3" Grid.Column="0" Tap="testsList_Tap" >
<ListBox.ItemTemplate>
<DataTemplate>
<!--ExpanderView-->
<toolkit:ExpanderView Header="{Binding}"
...
In your code behind file, implement the tap handler:
private void testsList_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
someModel selectedItem = (someModel)this.testsList.SelectedItem;
// Do something with your seleted data
...
}
you can get the selected values by listbox selectionchanged or expanderview expanded events.
For listbox :
private void lstExams_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (e.AddedItems.Count > 0)
{
Model.ExamTitles data = (sender as ListBox).SelectedItem as Model.ExamTitles;
}
}
Here ExamTitles is a class which contains collections
For expanderview Expanded
private void ExpanderView_Expanded(object sender, RoutedEventArgs e)
{
ExpanderView expview = (sender as ExpanderView);
Model.ExamTitles data = expview.Header as Model.ExamTitles;
}
Hope this helps!
So I have the following DataTemplate for a ListBox.ItemTemplate:
<DataTemplate x:Key="Tweet">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Image
Grid.Column="0"
Source="{Binding ProfileImageURL}"
Width="50" Height="50"/>
<Grid Grid.Column="1">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock
Grid.Row="0"
FontSize="15"
FontWeight="Bold"
Text="{Binding User}"/>
<TextBlock
Grid.Row="1" TextWrapping="Wrap"
Text="{Binding Status}"/>
<DockPanel
Grid.Row="2">
<TextBlock
DockPanel.Dock="Left"
FontSize="10" TextWrapping="WrapWithOverflow"
Text="{Binding TimeAgo}" TextAlignment="Justify"/>
<TextBlock
DockPanel.Dock="Left"
FontSize="10" TextWrapping="Wrap"
Text="{Binding Source}"/>
</DockPanel>
</Grid>
</Grid>
</DataTemplate>
The problem is that it doesn't auto-size to the ListBox. The text gets clipped:
TwitBy preview
How to fix it?
Here's the listBox XAML definition:
<ListBox
x:Name="tweetsListBox"
Margin="3,0"
Grid.Row="1"
Background="{x:Null}" Grid.IsSharedSizeScope="True"
ItemsSource="{Binding}" ScrollViewer.HorizontalScrollBarVisibility="Disabled"
ItemTemplate="{DynamicResource Tweet}"/>
Any help would be appreciated.
Thanks
Try this:
<DataTemplate x:Key="Tweet">
<Grid Width="{Binding ElementName=tweetsListBox, Path=ActualWidth>">
