I want to use a usercontrol I found on the web in my WPF application. The thing is that I don't want to have to put it in a user control library and build it and then reference that. I just want to be able to import the files into my project and use it from there.
So what I have done is dragged the files into the solution explorer, and it added them okay. I then changed the namespaces to match my own and then attempted to add it to the main forms xaml(This is where my issue is.)
It says the type "local:Pie" is not found. Verify that you are not missing an assembly reference...and you know the rest.
Here is how I am calling it on my main for xaml:
<Grid>
<local:Pie Value="0" x:Name="pieChart" HorizontalAlignment="Center" Width="400" VerticalAlignment="Center" Margin="10"/>
<StackPanel HorizontalAlignment="Left" Margin="30,0,50,0" VerticalAlignment="Center">
<Slider Orientation="Vertical" Minimum="0" Maximum="1" TickFrequency="0.01" Height="272" ValueChanged="Slider_ValueChanged_1" Value="0" Name="slider"/>
</StackPanel>
</Grid>
Here is the controls XAML with my application namespace added:
<UserControl x:Class="MyApplicationNAmespace.Pie"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300" Loaded="UserControl_Loaded_1" SizeChanged="UserControl_SizeChanged_1">
<Grid>
<Ellipse Name="bgCircle"/>
<Path Name="path" StrokeThickness="1.5" Margin="0"/>
<Ellipse Name="hole" RenderTransformOrigin="0.5,0.5">
<Ellipse.RenderTransform>
<ScaleTransform ScaleX="0.45" ScaleY="0.45"/>
</Ellipse.RenderTransform>
</Ellipse>
<Label Content="Value" HorizontalAlignment="Center" VerticalAlignment="Center"
FontFamily="Segoe UI Light" FontSize="38" Name="lblValue"
VerticalContentAlignment="Center" HorizontalContentAlignment="Center"/>
</Grid>
</UserControl>
For the codebehind of the control all I have changed was the namespace to match my projects namespace.
Can anyone tell me what I am doing wrong? Thank you.

I'm working on a UWP application and need some help with Flyout. I have a Flyout in my XAML with a few TextBlock elements but don't seem to be able to call those elements in the Code Behind. Everytime I try that, I get an Exception "The name TB does not exist in the current context."
I already searched for possible solutions and tried the following things: Made a clean build, Restarted VS 2017, Cleared the bin folder manually and then tried to rebuild
But nothing seems to work and I'm on a point where I don't know what to do.

I expect to call TB.Text = "xyz" for example from the Code Behind page, but at the moment I'm not able to call it.
I'm still able to call the other elements outside from the Flyout like "CmbSelectParkhaus" though.
You cannot handle things inside a DataTamplate, datamplates are not actual ui entities, they are Templates.
Assuming you want to achieve the same kind of access across all of your GridView items, you have to attach dependency properties, and either create programmatic binds on the PrepareContainerForItemOverride or the appropriate xaml "{Binding}" expressions.
This just opens whole new rabbit hole, especially if you are unaware of at least a single thing i mentioned so far, but you can just look up the bolded words one by one.
I have this button from Main window.xaml need to call it from another class
i made it just like first answer
How to make a control in XAML public in order to be seen in other classes
<Window x:Class="USD.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="450" Width="525">
<Button ToolTip="Answer Call" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="107,82,0,0" x:Name="answerCall" Click="answerCall_Click" Visibility="Hidden" x:FieldModifier="public">
<StackPanel Orientation="Horizontal" >
<Image Width="35" Height="35" Source="Images/unnamed.png" RenderTransformOrigin="4.075,0.607">
</Image>
</StackPanel>
<Button.Template>
<ControlTemplate TargetType="Button">
<Grid>
<ContentPresenter HorizontalAlignment="Center"
VerticalAlignment="Center"/>
</Grid>
</ControlTemplate>
</Button.Template>
</Button>
but when i checked it from any .cs class just like that
MainWindow.answerCall.Visibility.Visible;
give errors
i fixed it by this in C# code
DispatcherPriority.Background,
new Action(() => ((MainWindow)System.Windows.Application.Current.MainWindow).answerCall.Visibility = Visibility.Visible));
If you use a controller/viewmodel, you shouldn't have any code behind, instead of that, you should work with bindable properties and commands, implementing INotifyPropertyChanged interface, in some base class if you want.
In my application I have a control which renders a number of blocks on a timeline view (like a calendar). One can provide a template for the blocks by giving the timeline an appropriate DataTemplate.
I would like to separate the block DataTemplate from the main timeline view, putting the block into its own XAML. As such, I've created a XAML for the Block (called Block.xaml) and wrapped the DataTemplate inside a ResourceDictionary, inside this XAML.
I've added a code behind to the XAML (called Block.xaml.cs) in which I need to access some of the elements in the block. The issue is that ResourceDictionaries seem to hide the elements from the codebehind such that I can't access them. I can't use a UserControl instead - this seems to not work.
How can I access the elements of the Block DataTemplate from the code behind?
Many thanks in advance for your help.
Block.xaml:
<ResourceDictionary x:Class="Project.Windows.MainInterface.TimelinePanel.Block" 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="clr-namespace:Project.Windows.MainInterface.TimelinePanel" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:converters="clr-namespace:Project.Converters" >
<DataTemplate x:Key="ItemBlockTemplate">
<Grid Name="BlockParent" Width="Auto" Height="Auto" MinHeight="50" ClipToBounds="True" SizeChanged="BlockParent_OnSizeChanged">
<Border Panel.ZIndex="3" BorderBrush="{DynamicResource BackgroundGreyLight}" BorderThickness="1" CornerRadius="1" />
<Grid Margin="1" Background="{DynamicResource BlockBackgroundGradient}" d:LayoutOverrides="Width">
<TextBlock x:Name="blockName" Height="20" Margin="4,0,4,0" Padding="3" VerticalAlignment="Top" Panel.ZIndex="3" FontSize="10" Foreground="{DynamicResource TextLight}" Text="{Binding blockName}" TextTrimming="CharacterEllipsis" Visibility="Visible" />
<TextBlock x:Name="Duration" Margin="0,2,4,2" Padding="0,0,3,0" HorizontalAlignment="Right" VerticalAlignment="Bottom" Panel.ZIndex="5" FontSize="10" Foreground="{DynamicResource TextLight}" Text="{Binding FormattedDuration}" ToolTip="{Binding Duration}" />
<Grid Background="#FF0FA8FF" Opacity="0.7" />
</Grid>
</Grid>
</DataTemplate>
Snippet of the Timeline in the main interface:
...
<timeLineTool:TimeLineControl x:Name="Timeline" Height="50" MinWidth="50" Margin="0,0,12,0" HorizontalAlignment="Left" VerticalAlignment="Top" Items="{Binding Timeline}" SnapsToDevicePixels="True" UnitSize="{Binding UnitSize}" UseLayoutRounding="True">
<timeLineTool:TimeLineControl.ItemTemplate>
<DataTemplate DataType="{x:Type local:BlockItemViewModel}">
<ContentControl>
<ContentPresenter Margin="0" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Content="{Binding}" ContentTemplate="{StaticResource ItemBlockTemplate}" />
</ContentControl>
</DataTemplate>
</timeLineTool:TimeLineControl.ItemTemplate>
</timeLineTool:TimeLineControl>
...
...If I could use a UserControl instead of a ResourceDictionary for my Block, this would solve the problem, as all elements are automatically publicly available in the code behind for usercontrols.
Sample XAML:
<Window.Resources>
<ControlTemplate x:Key="ResourceName" TargetType="{x:Type Label}">
<Label Foreground="White" Content="{iconPacks:PackIconFontAwesome plug,Height=40,Width=40}"/>
</ControlTemplate>
</Window.Resources>
Code behind
ControlTemplate Dictionary:
private Dictionary<string, ControlTemplate> collection
{
get
{
Dictionary<string, ControlTemplate> controlTemplates = new Dictionary<string, ControlTemplate>();
controlTemplates.Add("ResourceName", FindResource("ResourceName") as ControlTemplate);
return controlTemplates;
}
}
Use ControlTemplate:
Label LBDisConnect = new Label();
LBDisConnect.Template = collection["ResourceName"];
LoginInfo.Children.Add(LBDisConnect);
I have been using MahApp.Metro for a few project now, and WinForms charts too, and also combined them.
So nothing new on that front in this project, except :
The placement of the chart.
And this is causing an issue where the Mahapps.Metro Flyout menu i have opens BEHIND the chart. See Screenshot.
Is there any way to solve this? i have searched a bit and found nothing. In CSS it would be a simple z-index setting... but in C# i have no idea.
Any help appreciated.

That's a known issue when mixing WinForms and WPF and is not related to MahApps.Metro. Just search for Airspace here at StackOverflow.
I have a project consisting of two pages. One page is having th XAML of a User control developed by me.
The another page has the logic of cropping the image that is present in the image box on that page. I want to use my control on that page and assign the border background of the user control to the image cropped .

In the user control XAML , we can see that I have set the

Any help would be appreciated
