C# WPF LiveCharts toggle chart associated to legend item - c#

Hello Can anyone advice how to make LiveCharts on legend item click toggle charts visibility(on/off), code below:
<lvc:CartesianChart Height="312" Width="389" LegendLocation="Bottom" Pan="None">
<lvc:CartesianChart.ChartLegend>
<lvc:DefaultLegend Tag="1" MouseLeftButtonDown="DefaultLegend_Click">
</lvc:DefaultLegend>
</lvc:CartesianChart.ChartLegend>
<lvc:CartesianChart.DataTooltip>
<lvc:DefaultTooltip SelectionMode="SharedYInSeries" />
</lvc:CartesianChart.DataTooltip>
<lvc:CartesianChart.Series>
<lvc:LineSeries Visibility="Visible" Values="9,5,5,1,0,8" Title="Chart One"/>
<lvc:LineSeries x:Name="FirstChart" Visibility="Visible" Values="19,15,15,11,10,18" Title="Chart Two"/>
</lvc:CartesianChart.Series>
</lvc:CartesianChart>
I tried to use Livecharts examples but assigning mouseleftbutton event works not on legend item, but on whole layer, how can assign event on just item not on whole legend layer?

You'll have to override default template in order to receive MouseLeftButtonDown event on individual legend as default legend is just a collection of series.
<lvc:DefaultLegend.Template>
<ControlTemplate>
<ItemsControl ItemsSource="{Binding Series}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" MouseLeftButtonDown="StackPanel_MouseLeftButtonDown">
<Ellipse Height="16"
Width="16"
Stroke="{Binding Stroke}"
StrokeThickness="{Binding StrokeThickness}" />
<TextBlock Text="{Binding Title}" Padding="5" Margin="5" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</ControlTemplate>
</lvc:DefaultLegend.Template>

i am working on state machine test design tool, but i am facing issue with dragging and drop the added nodes in the design panel. Since these nodes are added in the run-time. i can not implement the drag drop event for each added node , knowing that i am using WPF with caliburn.micro platform and MVVM
XAML code

Image of UI
I found the answer of my question in https://www.codeproject.com/Articles/15354/Dragging-Elements-in-a-Canvas
I integrated class DragCanvas.cs into my project and included following line in the header of the XAML file
xmlns:jas="clr-namespace:WPF.JoshSmith.Controls"
and XAML code became
<!-- Column 2 : Design panel-->
<jas:DragCanvas x:Name="DesignPanelState"
Grid.Column="2" Grid.RowSpan="3"
AllowDragging="{Binding ElementName=Move, Path=IsChecked}"
AllowDragOutOfView="False">
<ItemsControl x:Name="Nodes">
<ItemsControl.ItemsPanel >
<ItemsPanelTemplate >
<Canvas AllowDrop="True"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate >
<DataTemplate>
<Button x:Name="NodeIdx" BorderBrush="Aquamarine" BorderThickness="1" Content="{Binding NodeName}" MinWidth="50" MinHeight="50"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</jas:DragCanvas>

How to display listbox items in column view in WPF c#

Am using listbox control in WPF its display listbox item in row wise but I want to display in column wise ( Something like bootstrap grid)
XMAL
<ListBox x:Name="lb_items">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="10 0 0 0">
<Image Source="{Binding ImageSource}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Am binding Listbox from code behind
lb_items.ItemsSource = modules.ToList();
Try this one.
<ListBox x:Name="lb_items">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Margin="10 0 0 0">
<Image Source="{Binding ImageSource}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
ListBox has property called ItemsPanel, which determines how items are rendered.
Somewhere in application resource create different ItemsPanelTemplate, so you can easily reuse it:
<ItemsPanelTemplate x:Key="WrapPanelTemplate">
<WrapPanel />
</ItemsPanelTemplate>
<ItemsPanelTemplate x:Key="HorizontalStackPanelTemplate">
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
then you can easily use it:
<ListBox ItemsPanel="{StaticResource HorizontalStackPanelTemplate}">...
<ItemControl ItemsPanel="{StaticResource WrapPanelTemplate}">...
always put such assets into application resources in order to make the code for your views clean and readable.
Extra Tip:
Here is animated WrapPanel, that animates items, when you resize window or an item is inserted to the list:
<ItemsPanelTemplate x:Key="FluidWrapPanel">
<WrapPanel>
<i:Interaction.Behaviors>
<ei:FluidMoveBehavior AppliesTo="Children" Duration="0:0:0.5">
<ei:FluidMoveBehavior.EaseY>
<SineEase EasingMode="EaseInOut" />
</ei:FluidMoveBehavior.EaseY>
<ei:FluidMoveBehavior.EaseX>
<CubicEase EasingMode="EaseInOut" />
</ei:FluidMoveBehavior.EaseX>
</ei:FluidMoveBehavior>
</i:Interaction.Behaviors>
</WrapPanel>
</ItemsPanelTemplate>
dont forget to include these xml namespaces:
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions"

Listview in WinRT using C#

I want my ListView to display the items in a group horizontally as displayed in the image below. I could not find anything relating to this online. This screen was taken from the Groove music application. Since I am new to asking questions here it seems I don't have enough reputation to post images therefore I provided a link to the image in question sorry for the inconvenience.

Edit:
I am trying to imitate the groove music player for a school project this link below shows my app. Hopefully this give you a better idea of the problem.

My Xaml Code:
<ListView
x:Name="itemGridView"
Grid.Row="1"
ItemsSource="{Binding Source={StaticResource artistsItemsViewSource}}"
SelectionMode="None"
IsSwipeEnabled="false"
IsItemClickEnabled="True"
RequestedTheme="Light">
<ListView.ItemTemplate>
<DataTemplate>
<StackPanel MaxWidth="200">
<Ellipse Height="150" Width="150">
<Ellipse.Fill>
<ImageBrush Stretch="Fill" ImageSource="Assets/Artist.png"/>
</Ellipse.Fill>
</Ellipse>
<TextBlock Text="{Binding ArtistName}" FontSize="18" HorizontalAlignment="Center" Margin="0,5,0,0" TextWrapping="Wrap"/>
<TextBlock Text="{Binding AlbumCount}" FontSize="15" HorizontalAlignment="Center" Margin="0"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsStackPanel Width="200" HorizontalAlignment="Left" Margin="30,0,0,0"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.GroupStyle>
<GroupStyle>
<GroupStyle.HeaderTemplate>
<DataTemplate>
<Grid Margin="0,0,0,2">
<TextBlock Text="{Binding AlphaLetter}" FontSize="20" Foreground="{StaticResource SideButtonBlue}" />
</Grid>
</DataTemplate>
</GroupStyle.HeaderTemplate>
</GroupStyle>
</ListView.GroupStyle>
</ListView>
I think you can change the view in the listview settings to LargeIcon and then you can set Icons for each value in your listview.
But you could maybe use the ObjectListView its better than the plain ListView and you have more functions. check this out: click
I found something similar on the site of the objectlistview: here
for horizontal placement of the elements in ListView do this:
<ItemsStackPanel
Orientation="Horizontal" />
also, remove Width="200"
also you can use GridView instead of ListView

Changing border color when a control is selected with c# on windows 8 app store

I have a gridview control with images and text with this xaml:
<Grid Grid.Column="1" Margin="0,40,30,0" >
<GridView x:Name="celebGridView" Margin="0,0,0,0" Padding="0,0,0,0">
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" MaximumRowsOrColumns="3"/>
</ItemsPanelTemplate>
</GridView.ItemsPanel>
<GridView.Header>
<StackPanel Width="480" Margin="0,4,14,0">
<StackPanel Orientation="Horizontal" Margin="0,0,0,10">
<TextBlock Text="Most Viewed Celebs" Foreground="black" FontSize="25"/>
<Image Source="/images/Navigation-Right.png" Margin="10,0,0,0"/>
</StackPanel>
</StackPanel>
</GridView.Header>
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel>
<Image Source="{Binding ImageBitmap}" />
<TextBlock HorizontalAlignment="Center" Text="{Binding Name_}" Foreground="Black"/>
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
and i get this purple border around the selected items in the gridview below
How can i override this behaviour, i need to change the color to a custom color (#fdeb01).
You could edit the ItemContainerStyle for the GridView. The easiest way is to use Blend and find the SelectedBorder element and change stroke brush to color you want.
Aside from using Expression Blend, note that Metro ListView selection color modification in XAML is also valid for GridViewItems so changing the following:
<SolidColorBrush x:Key="ListViewItemSelectedBackgroundThemeBrush" Color="#fdeb01"> </SolidColorBrush>
<SolidColorBrush x:Key="ListViewItemPointerOverBackgroundThemeBrush" Color="#ffffff"></SolidColorBrush>
<SolidColorBrush x:Key="ListViewItemSelectedPointerOverBackgroundThemeBrush" Color="#fdeb01"></SolidColorBrush>
<SolidColorBrush x:Key="ListViewItemSelectedPointerOverBorderThemeBrush" Color="#fdeb01"></SolidColorBrush>
will also affect the gridview.

Different Object-Types in Grid- or ListView

I'm currently trying to figure out how to show different types of objects in a GridView, look at this Pic for example:
the last element on the right side is different than the other elements, so if i bind an observablecollection to the GridView, how can i say that the last element is shown up in anohter layout.
currently I'm using this XAML-Code
<GridView x:Name="startView" ItemsSource="{Binding}" Grid.Column="1" Grid.Row="2" SelectionMode="None" Width="Auto">
<GridView.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock x:Name="DetailTitle" Height="74" Text="{Binding Title}" />
<Image x:Name="Image" Height="Auto" Width="Auto" Margin="0" Stretch="None" Source="{Binding LocalCoverUrl}" Visibility="Collapsed" />
</StackPanel>
</DataTemplate>
</GridView.ItemTemplate>
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid Orientation="Horizontal" MaximumRowsOrColumns="2" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
</GridView>
and this Code in the Back:
ObservableCollection<Movie> recentlyStarted = await Api.RecentlyStarted(3);
startView.DataContext = recentlyStarted;
but I have currently no clue how to let the last element show up in a different style
The easy way would be to have the two types of object as different classes (e.g. MoviePicStyle + MoviePlainStyle. Then move your DataTemplate out of the GridView, so that each object is picked up by type,
e.g.
<Window.Resources>
<DataTemplate DataType="{x:Type ViewModel:MoviePicStyle}">
<StackPanel>
<TextBlock x:Name="DetailTitle" Height="74" Text="{Binding Title}" />
<Image x:Name="Image" Height="Auto" Width="Auto" Margin="0" Stretch="None" Source="{Binding LocalCoverUrl}" Visibility="Collapsed" />
</StackPanel>
<DataTemplate DataType="{x:Type ViewModel:MoviePlainStyle}">
...Different View...
</DataTemplate>
</Window.Resources>
<GridView...
Use template selector property of gridview and depending upon the type of object select the template. I did the same in my project. you need to write your own DataTemplateSelector.
