How to make only a part of gridview item clickable in uwp application?

I'm using a grid view control in my uwp application and each grid view item contains a grid and a stackpanel. I want to make only grid to be clickable instead on the complete grid view item.
Here is my grid view code
<GridView
Grid.Row="1"
ItemsSource="{x:Bind ViewData}"
ScrollViewer.VerticalScrollBarVisibility="Hidden"
Margin="130,40,130,40">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:ViewArr">
<StackPanel Margin="50,25,50,25" >
<Grid Height="120" Width="120">
<Image
Source="assets/images/icons/check_my_blue.png"
Height="40"
Width="40"
Canvas.ZIndex="99"
Margin="80,0,0,80">
</Image>
<Canvas>
<Ellipse
Height="120"
Width="120"
Fill ="{x:Bind profile_color , FallbackValue='#00000'}"
StrokeThickness="3"
Stroke="Black" >
</Ellipse>
</Canvas>
<TextBlock
Text="{x:Bind profile_name}"
VerticalAlignment="Center"
HorizontalAlignment="Center"
FontSize="28"
Foreground="White">
</TextBlock>
</Grid>
<StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="0,10,0,0">
<TextBlock Text="{x:Bind first_name}" FontSize="16" FontWeight="Bold" ></TextBlock>
<TextBlock Text="{x:Bind last_name}" FontSize="16" FontWeight="Bold"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="0,10,0,0">
<TextBlock Text="Today - " FontSize="14" FontWeight="Bold" Foreground="Gray" Margin="0,0,5,0"></TextBlock>
<TextBlock Text="0" FontSize="14" Foreground="Gray"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="0,10,0,0">
<TextBlock Text="Previous Tasks - " FontSize="14" FontWeight="Bold" Foreground="Gray" Margin="0,0,5,0"></TextBlock>
<TextBlock Text="0" FontSize="14" Foreground="Gray"></TextBlock>
</StackPanel>
</StackPanel>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
And it creates something like this.

I want to make only circles to be clickable not the text below that.
Is there any way to achieve that? Please guide me. Thanks in advance.

How to make only a part of gridview item clickable in uwp application?
For your requirement, you could set GridView IsItemClickEnabled property as false then listen Grid Tapped event like following.
<GridView IsItemClickEnabled="False" >
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Grid Tapped="Grid_Tapped"
Width="30"
Height="30"
VerticalAlignment="Center"
Background="Red"
CornerRadius="15"
/>
<StackPanel VerticalAlignment="Center" Orientation="Vertical">
<TextBlock VerticalAlignment="Center" Text="NicoName" />
</StackPanel>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
private void Grid_Tapped(object sender, TappedRoutedEventArgs e)
{
}

Try this.
<GridView
Grid.Row="1"
Margin="130,40,130,40"
IsItemClickEnabled="False"
ScrollViewer.VerticalScrollBarVisibility="Hidden">
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Margin="50,25,50,25">
<Button
BorderBrush="Transparent"
BorderThickness="0"
Command="{Binding MyCommandName}"
Foreground="Transparent">
<Grid Width="120" Height="120">
<Image
Width="40"
Height="40"
Margin="80,0,0,80"
Canvas.ZIndex="99"

<Canvas>
<Ellipse
Width="120"
Height="120"
Fill="{x:Bind profile_color, FallbackValue='#00000'}"
Stroke="Black"
StrokeThickness="3" />
</Canvas>
<TextBlock
HorizontalAlignment="Center"
VerticalAlignment="Center"
FontSize="28"
Foreground="White"
Text="{x:Bind profile_name}" />
</Grid>
</Button>
<StackPanel>
<StackPanel

<TextBlock

Text="{x:Bind last_name}" />
</StackPanel>
<StackPanel
Margin="0,10,0,0"
HorizontalAlignment="Center"
Orientation="Horizontal">
<TextBlock
Margin="0,0,5,0"
FontSize="14"
FontWeight="Bold"
Foreground="Gray"
Text="Today - " />
<TextBlock

How to horizontally align controls?

I'm trying to align below controls horizontally by keeping the label and the combobox on the left and both buttons on the right. I've tried different approaches using StackPanel but nothing gives me the desired output. Appreciate if you guys could point out what am I doing wrong here?
Current Layout
XAML source
<StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Center" Orientation="Vertical" Margin="0,0,0,2" >
<StackPanel Orientation="Horizontal" VerticalAlignment="Center">
<StackPanel HorizontalAlignment="Left" Orientation="Horizontal" VerticalAlignment="Center">
<Label Content="Age Bucket" HorizontalAlignment="Left" VerticalAlignment="Center" />
<ComboBox HorizontalAlignment="Left" VerticalAlignment="Center" Margin="10,0,0,0" Width="100"
SelectedValue="{Binding SelectedAgeBucket}"
DisplayMemberPath="DisplayMember" SelectedValuePath="ValueMember"
ItemsSource="{Binding AgeBuckets}" IsSynchronizedWithCurrentItem="True"/>
</StackPanel>
<StackPanel HorizontalAlignment="Right" VerticalAlignment="Center" Orientation="Horizontal" Margin="0,0,0,2">
<Button Click="Button_Click_1" Content="Export" HorizontalAlignment="Right" />
<Button HorizontalAlignment="Right" VerticalAlignment="Center" Click="Button_Click_2" Content="Print" Margin="5,0" />
</StackPanel>
</StackPanel>
<telerik:RadDataPager x:Name="radDataPager" Source="{Binding Items, ElementName=grdDetails}" PageSize="100" />
</StackPanel>

How to get Text in GridView when selected?

I'm working on a project in which I'm setting content using JSON Binding in Grid view but now I want to get Text of item when it is selected. XAML CODE:
<GridView ItemsSource="{Binding}" HorizontalAlignment="Center" Margin="0,10,0,0" x:Name="dataList" VerticalAlignment="Center" SelectionMode="None" SelectionChanged="dataList_Selection">
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel Width="450" Height="300">
<Image Source="{Binding Top}" Margin="0,0,0,0" Stretch="None" />
<TextBlock x:Name="title" Text="{Binding Title}" Foreground="Black" HorizontalAlignment="Center" FontFamily="Assets/Font/MixBrush.ttf#MixBrush" FontWeight="Bold" FontSize="50" Margin="0,10,0,0" />
<Image Source="{Binding Bottom}" Margin="0,0,0,0" Stretch="None" />
<TextBlock Text="{Binding first}" Foreground="Black" HorizontalAlignment="Center" FontFamily="Assets/Font/Comfortaa_Regular.ttf#Comfortaa" FontSize="20" Margin="0,50,0,0" />
<TextBlock Text="{Binding second}" Foreground="Black" HorizontalAlignment="Center" FontFamily="Assets/Font/Comfortaa_Regular.ttf#Comfortaa" FontSize="20" Margin="0,0,0,0" />
<TextBlock Text="{Binding third}" Foreground="Black" HorizontalAlignment="Center" FontFamily="Assets/Font/Comfortaa_Regular.ttf#Comfortaa" FontSize="20" Margin="0,0,0,0" />
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
Here I want to get Text of "title" programmatically. Please share your knowledge with me. :-)
********************** Thank You ************************

On your back code use:
title.Text;

After long hard struggle I found my answer.
var selection = (myClass) dataList.SelectedItem;
await new MessageDialog(selection.Title).ShowAsync();
And I got perfect result.
Thank You.

Listbox No Scrollbar

I have been up and down looking on the internet and many people seem to have this problem but its generally solved by changing the container to a grid, constraining the height etc. etc. I can't to seem to get this to work.
I have an observableCollection thats feeding into a DataTemplate. I can't for th life of me get the scrollbar working. Its there but not enabling. Thanks Scott

Must be a bug. I have the following only..
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="ComfortReportEng.Views.EngineerReport.EngineerReport"
Title="Engineer Report" WindowStartupLocation="CenterScreen" Loaded="Window_Loaded" SizeToContent="WidthAndHeight" >
<Window.Resources>
<CollectionViewSource x:Key="cvsReportList"/>
</Window.Resources>
<Grid Margin="0.125,0.412,3.125,0" Height="471">
<ListBox Margin="23,64,3,0" Width="834.14" ItemsSource="{Binding Source={StaticResource cvsReportList}}"
x:Name="lbReportList" SelectionChanged="lbReportList_SelectionChanged" Background="#FFEEEFE4" />
</Grid>
and code is
private void LoadReportList()
{
int number = 0;
List<int> myNumbers = new List<int>();
while (number < 80)
{
myNumbers.Add(number);
number += 1;
}
_cvsReportList = (CollectionViewSource)(this.FindResource("cvsReportList"));
_cvsReportList.Source = myNumbers;
}
This was copied over from another project. Completely confused. Please don't worry. It's not a logical problem. Please take this as a close call with no solution. Cheers again Scott
Just to give this completeness. I am not sure why this happens but here is it.
if (System.Environment.MachineName == "SCOTT-PC")
{
this.txtUserName.Text = "Scott Fisher";
this.txtPassword.Password = "palace";
//LoginOK();
}
else
Keyboard.Focus(this.txtUserName);
If I clear the comments on LoginOK procedure I will get no scrollbar. With it commented and I interact with the login screen then everything is fine. Finally here is the code for the LoginOK.
if (LoginService.CheckLogin(txtUserName.Text, txtPassword.Password.ToString()))
{
Helpers.User.ThisUser = this.txtUserName.Text;
EngineerReport.EngineerReport engReport = new EngineerReport.EngineerReport()
{
Owner = Window.GetWindow(this),
WindowStartupLocation =
System.Windows.WindowStartupLocation.
CenterOwner
};
this.Hide();
engReport.ShowDialog();
}
else
{
this.txtPassword.Password = "";
this.txtPassword.Focus();
}

Can you provide you DataTemplate as I believe I have just managed to mock up what you are trying to achieve and I have scrollbars visible and working form the start.
Here is the xaml that I used for the DataTemplate for the ListBox:
<ListBox DataContext="{StaticResource MusicData}" ItemsSource="{Binding XPath=Album}">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem>
<StackPanel Orientation="Horizontal" >
<TextBlock>No.</TextBlock>
<TextBlock Text="{Binding XPath=No}"></TextBlock>
<TextBlock>Title</TextBlock>
<TextBlock Text="{Binding XPath=Title}"></TextBlock>
</StackPanel>
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Hope this helps.
I also found a piece of code I used a while back and this might help. You can try setting the ItemsPanelTemplate:
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel>
<ScrollViewer VerticalScrollBarVisibility="Visible" />
</StackPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
This will work with any items control as stated in this article:
http://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.itemcontainerstyle.aspx
One final thing I can suggest is to create your own ControlTemplate for the ListBox Like so:
<ListBox.Template>
<ControlTemplate>
<ScrollViewer VerticalScrollBarVisibility="Auto">
<ItemsPresenter />
</ScrollViewer>
</ControlTemplate>
</ListBox.Template>

TextTrimming not working

I have data binding to a listbox, and texttrimming property set to WordEllipsis, but it doesn't seem to work. The textblocks are showing text as if they do without the texttrimming property set. This is my xaml code. Please help.
<Grid>
<Grid.Resources>
<application:ViewModel x:Key="ViewModel"/>
</Grid.Resources>
<TextBlock Height="75" TextWrapping="Wrap" Text="Click on Settings to search for quotes (by author or by query)." VerticalAlignment="Top" TextAlignment="Center" FontSize="26.667"/>
<ListBox Margin="0,166,0,0" Name="lstQuote" DoubleTap="lstQuote_DoubleTap" Hold="lstQuote_Hold">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<es:RegularPolygon Fill="#FFF4F4F5" Height="90" InnerRadius="0.47211" PointCount="5" Stretch="Fill" Stroke="Black" UseLayoutRounding="False" Width="84"/>
<StackPanel Orientation="Vertical" Margin="0,10,0,0">
<TextBlock Text="{Binding Author}" TextWrapping="Wrap" FontSize="24"/>
<TextBlock Text="{Binding Quote}" TextWrapping="NoWrap" FontSize="30" TextTrimming="WordEllipsis" Width="Auto" />
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Button Content="Random Quote" Height="79" Margin="48,83,44,0" VerticalAlignment="Top" x:Name="quotSearch" Click="quotSearch_Click" />
</Grid>

change TextBox Width properties to fixed width
<TextBlock Width="200" Height="75" TextWrapping="Wrap" Text="Click on Settings to search for quotes (by author or by query)." VerticalAlignment="Top" TextAlignment="Center" FontSize="26.667"/>
