Childwindow WPF extended toolkit not opening - c#

This is my code to open childwindow:
ImageLocation location = new ImageLocation();
location.WindowStartupLocation = Xceed.Wpf.Toolkit.WindowStartupLocation.Center;
location.Show();
But the childwindow doesn't show at all.
This is my xaml for childwindow:
<xctk:ChildWindow x:Class="CXLocalSearch.Dialogs.ImageLocation"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Caption="Image Path"
xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
Height="64" Width="400">
<Grid x:Name="LayoutRoot">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" MinWidth="63.95"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Margin="2" TextWrapping="Wrap" Text="Image Path" VerticalAlignment="Center" HorizontalAlignment="Left"/>
<StackPanel Grid.Column="1" HorizontalAlignment="Left" Margin="3,2,0,2" Orientation="Horizontal" >
<TextBox x:Name="txtPath" Margin="0,2" TextWrapping="Wrap" VerticalAlignment="Center" Width="250"/>
<Button x:Name="btnSave" Content="Save" Click="btnSave_Click" Width="60" Margin="3,0,0,0"/>
</StackPanel>
</Grid>
</xctk:ChildWindow>
Could anybody please clarify what the issue is?

From the looks of it, you've separated your ChildWindow into a separate control. That's fine, but it needs to be hosted inside a primary window in order to ever become visible. Start with the simplest thing possible:
<Window>
<Grid>
<Button Click="...">Click to Show</Button>
<xctk:ChildWindow x:Name="childWindow">
<TextBlock>Hello!</TextBlock>
</xctk:ChildWindow>
</Grid>
</Window>
I think you'll find this works fine (assumes event hookup), so take it from there.

Access Popup-Dialog inside a data template

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"
Margin="36,62,34,68"
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"
Margin="0,0,5,0"
HorizontalAlignment="Left"
RelativePanel.AlignLeftWithPanel="True"
Symbol="Globe" />
<TextBlock HorizontalAlignment="Right"
VerticalAlignment="Top"
RelativePanel.RightOf="symbol"
Style="{ThemeResource BaseTextBlockStyle}"
Text="Category" />
</RelativePanel>
</StackPanel>
<StackPanel Grid.Column="1" HorizontalAlignment="Center">
<RelativePanel>
<SymbolIcon x:Name="symboll"
Margin="0,0,5,0"
HorizontalAlignment="Left"
RelativePanel.AlignLeftWithPanel="True"
Symbol="People" />
<TextBlock HorizontalAlignment="Right"
VerticalAlignment="Top"
RelativePanel.RightOf="symboll"
Style="{ThemeResource BaseTextBlockStyle}"
Text="SubCategory" />
</RelativePanel>
</StackPanel>
<StackPanel Grid.Column="2" HorizontalAlignment="Right">
<RelativePanel>
<SymbolIcon x:Name="symbllol"
Margin="0,0,5,0"
HorizontalAlignment="Left"
RelativePanel.AlignLeftWithPanel="True"
Symbol="Bullets" />
<TextBlock HorizontalAlignment="Right"
VerticalAlignment="Top"
RelativePanel.RightOf="symbllol"
Style="{ThemeResource BaseTextBlockStyle}"
Text="Rupee" />
</RelativePanel>
</StackPanel>
</Grid>
<TextBlock Grid.Row="2"
HorizontalAlignment="Center"
Style="{ThemeResource ScenarioDescriptionTextStyle}"
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.

WPF app - not clickable anymore

I am new to WPF and suddendly my Window is not clickable anymore.
I cannot click one button and I cannot edit a text box.
I am using Visual Studio 2015 (new to it as well).
What could be the reason?
here some code:
<Window x:Class="Mxx.MainWindow"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Mxx"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="26*"/>
</Grid.RowDefinitions>
<Menu>
<MenuItem Header="Log out" Click="MenuItem_Click1"/>
<MenuItem Header="Option 2">
<MenuItem Header="Load new control" Click="MenuItem_Click2a"/>
<MenuItem Header="Open new window" Click="MenuItem_Click2b"/>
</MenuItem>
</Menu>
<Border x:Name="Stage" Grid.Row="1"/>
<Grid x:Name="LoginLayer" Background="#FFFFFFFF" Grid.RowSpan="2">
<Grid HorizontalAlignment="Center" VerticalAlignment="Center" Background="LightBlue">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<TextBlock Text="Mxx" Grid.ColumnSpan="2" FontWeight="Bold" HorizontalAlignment="Center" Margin="5" FontSize="20"/>
<TextBlock Text="Name" Grid.Row="1" Margin="3"/>
<TextBox x:Name="txtName" Grid.Row="1" Grid.Column="1" Margin="3" MinWidth="100" HorizontalAlignment="Left"/>
<TextBox x:Name="txtName1" Background="Azure" Grid.Row="4" Grid.Column="1" Margin="3" MinWidth="100" HorizontalAlignment="Left"/>
<TextBlock Text="Password" Grid.Row="2" Margin="3"/>
<PasswordBox x:Name="txtPassword" Grid.Column="1" Grid.Row="2" Margin="3" MinWidth="100" HorizontalAlignment="Left"/>
<Button Click="Login_Click" Content="Log in" Grid.Row="3" Grid.Column="1" Margin="3"/>
</Grid>
<TextBlock x:Name="lat1" Text="lat" Grid.Row="4" Margin="3" />
</Grid>
</Grid>
and here my main window
public MainWindow()
{
InitializeComponent();
_geoLocator = new Geolocator();
Utils.getNetworkAdapterId();
Debug.WriteLine("imei: " + Properties.Settings.Default.imei);
Properties.Settings.Default.imei = "imei1";
Properties.Settings.Default.Save(); // Saves settings in application setting
}
my debugger hits the last line
Your problem is with the last declared TextBlock
<TextBlock x:Name="lat1" Text="lat" Grid.Row="4" Margin="3" />
That is outside of the grid that has row and column definitions, and so it is defaulting to taking up all the space in the page as an overlay. You are unable to give focus to the controls beneath it.
You can see this in the XAML editor window. In the code view, click on that element, and in the designer you will see that the textblock is the full size of your window. Because it is declared last in the XAML, it take the uppermost position (z-index) and therefore "hides" the controls behind it.
You have a TextBlock covering the other controls. I think you want to move lat1 into the /Grid tag directly above it.

WPF XAML Using Mouse Action Event

I am learning the WPF 4.5 Unleashed book. When I tried to incorporate Mouse Action Event such as MouseEnter or MouseDoubleClick for the Button by typing the code manually, the compiler told me it could not find the reference for the Mouse Action Event. However, when I use the double Tab shortcut, everything works well. What could possibly be the issue? I have bold the trouble code below.
<Window x:Class="WpfApplicationLearning0001.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="513.265" Width="748.469">
<DockPanel>
<Menu DockPanel.Dock="Top">
</Menu>
<StackPanel Name="ButtonBar" Orientation="Horizontal" DockPanel.Dock="Right">
<StackPanel.LayoutTransform>
<RotateTransform Angle="90">
</RotateTransform>
</StackPanel.LayoutTransform>
**<Button Name="Panel1Button" MouseEnter="Panel1Button_MouseEnter">
Toolbox
</Button>**
</StackPanel>
<Grid Background="White" Margin="0,0,2,3">
<Grid.RowDefinitions>
<RowDefinition Height="auto"/>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto" />
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Label Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" Background="Black" Foreground="White" HorizontalContentAlignment="Center" Content= "Start Page"/>
<GroupBox Grid.Row="1" Grid.Column="0" Background="White" Foreground="Black" Header="Start" />
<GroupBox Grid.Row="2" Grid.Column="0" Background="White" Foreground="Black" Header="Recent" />
<GroupBox Grid.Row="3" Grid.Column="0" Background="White" Foreground="Black" Header="Option" />
<GroupBox Grid.Row="1" Grid.Column="1" Grid.RowSpan="3" Background="White" Foreground="Black" Header="Get Start">
<ListBox>
<ListBoxItem>Article number1</ListBoxItem>
<ListBoxItem>Article number2</ListBoxItem>
<ListBoxItem>Article number3</ListBoxItem>
<ListBoxItem>Article number4</ListBoxItem>
</ListBox>
</GroupBox>
</Grid>
</DockPanel>
The double click not only puts it in the XAML code, put it also creates the code behind in the .cs file of:
private void Panel1Button_MouseEnter(object sender, MouseEventArgs e)
{
}
Until you add the code behind yourself, if you are doing it manually, then the error is correct. In addition, when manually coding be sure to include (object sender, MouseEventArgs e) in the function call or it may not recognize it as a valid function call to the MouseEvent.

WPF - Canvas Background Not Displaying

I am a complete newbie to WPF. I've been working on a personal project for about 2 weeks. It's been coming along, and suddenly hit a roadblock. Everything was working perfect until I shifted some things around.
It's basically a satellite map as the canvas background, so that I can overlay geometry on it. The image is 10000x10000, and has not changed. It's added as a resource and... funny enough, shows up in the Visual Basic xaml designer.
The local:ZoomBorder class zooms/pans the viewbox/canvas. I did not post the code because it has not been touched since it last worked.
Geometry is being added to the canvas correctly.
I moved around some dimensions, as far as the grid goes. Like adding margins and such, but can't get it back to displaying the imagebrush background, no matter what I do.

SizeToContent Fills Screen with RichTextBox and FlowDocumentScrollViewer

I'm trying to show a FlowDocument in a WPF form and have tried both RichTextBox and FlowDocumentScrollViewer. I also require that the window resizes to be able to show all text.
Unfortunately, when I set SizeToContent="WidthAndHeight" for the Window itself, no matter what content I put in the FlowDocument, the window expands to the full width of all my displays! The height seems to resize fine, however.
Anyone know how to get it to resize properly? Looked all over and cannot figure out how to get this going...
XAML below:
<Window x:Class="CustomControls.SecureConfirmationDialog"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="SecureConfirmationDialog"
MinHeight="120" MinWidth="200"
Height="120" Width="300"
ResizeMode="NoResize"
SizeToContent="WidthAndHeight"
WindowStyle="ToolWindow"
Loaded="Window_Loaded">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<FlowDocumentScrollViewer Name="flowMsg" Grid.Row="0" Grid.ColumnSpan="3" Margin="3" IsToolBarVisible="False" ScrollViewer.VerticalScrollBarVisibility="Hidden" />
<TextBox Name="txtConfirm" Grid.Row="1" Grid.Column="0" Text="Testing" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Margin="3" />
<Button Name="btnOK" Grid.Row="1" Grid.Column="1" Content="OK" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="3" Width="50" Click="btnOK_Click" />
<Button Name="btnCancel" Grid.Row="1" Grid.Column="2" Content="Cancel" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="3" Width="50" Click="btnCancel_Click" />
</Grid>
</Window>
SizeToContent only "works" if the content is actually bounded, in this case however the Grid, which is the content of Window, has no size restrictions so it will try to get all the space it can get, the window responds by giving it as much space as fits the screen.
If you want to prevent this you would need to make the container for your document to size to their content which might be impossible if the document does not have any bounds itself and also behaves in a give-me-all-you-have manner.
