I am using the Microsoft.Maps.MapControl.WPF dll in c# WPF.
Here is my issue in the picture below:
I use a custom template for the pushpin because I need to display some simple information for it. There is no infobox in the WPF version to my knowledge.
Clustering the pushpins together in one is not an option for me, because the pushpins represent a delivery location which needs to be displayed on the map. Zooming out is not an option for me because there could be a delivery on the other side of town which all need to be displayed by a bounding box including all pushpins.
Here is the code for my custom pushpin template:
<ControlTemplate x:Key="RedPushPinTemplate" TargetType="m:Pushpin">
<Grid >
<TextBlock Name="textBlock1" Text="{TemplateBinding Content}" Canvas.ZIndex="2" Height="75" Width="65" TextWrapping="Wrap" Grid.Column="0" Grid.Row="0" Foreground="Black"></TextBlock>
<Rectangle Width="35" Height="50" Margin="0 35 0 0" Canvas.ZIndex="1">
<Rectangle.Fill >
<ImageBrush ImageSource="pack://application:,,,/Images/redpin.jpg"/>
</Rectangle.Fill>
</Rectangle>
</Grid>
</ControlTemplate>
My question is, is there anyway to write code for the template that detects an overlap and do something nice to display the information for both pins. Better yet, is there an infobox control that someone is aware of that has this functionality built in?
Thank you very much for your time.
Sorry for the late answer.
How many Pushpins do you have? One Possiblity is to compare the List of Items (X&Y Coordinates + Radius) to find out which Pushpins Intersect eachother. Then you can adjust the X value and interate again.
You can also do this on the control level itself attaching a behavior which is constantly looking for pushpins and then see if they intersect.

I have an Image control in my view bound to BitmapSource prop in my View Model. This property is updated with images from a camera in my Model class. To get started with drawing shapes on images (so 1 control ON another),after
reading a similar post, I tried the following with a simple Rectangle
shape with Zindex=2 so it should act as an overlay over the image. But the
below doesn't work & all I see is the image from the camera
<Canvas>
<DockPanel Width="400" Height="250">
<Label DockPanel.Dock="Top" HorizontalAlignment="Center"
Content="IMAGE FROM CAMERA" Width="Auto"/>
<Image x:Name="CamImageDisplay"
DockPanel.Dock="Left"
Source="{Binding CurrentImage, Mode=OneWay}"
Stretch="None" Width="Auto"/>
<Rectangle Width="10" Height="5"
Fill="CadetBlue"
Panel.ZIndex="2" />
</DockPanel>
</Canvas>
I come from an MFC background where drawing shapes on bitmaps was as
easy as calling Draw3dRect(...). Having said that, my goal is to draw
a collection of shapes (just rectangles & circles) that will have
different co ordinates with each new image.
Could some one please
explain in simple terms or point to some reference that will show how
I can achieve this. Yes, there are other similar questions, but they
are really not quite aligned with my objectives. Thank you & please ask for clarifications if I am unclear in how I have asked my question.
I want to do something similar to Microsoft Powerpoint: I want to capture the current screen (or one grid from the current window), and then to set it as the content of the button (like powerpoint where there is a preview of the slides at the side bar).
What is the best way to do that? My current idea is to save it to PNG and then reload it as an image at the content of the button, but I'm sure there is a better way.
Thank you!
Try this:
<Grid>
<Viewbox
x:Name="Viewer"
Stretch="Uniform"
DataContext="{Binding ElementName=Thumbnail1, Path=Data}">
<Grid Width="224" Height="168" SnapsToDevicePixels="True" Margin="4,0,4,0">
<Grid.Background>
<VisualBrush Stretch="Uniform" TileMode="None" Visual="{Binding}" AlignmentY="Center"/>
</Grid.Background>
</Grid>
</Viewbox>
</Grid>
I was using saving as PNG approach in the beginning. Then I have found out the way as above. DataContext of the ViewBox is a canvas. I could create live previews of my screens this way however my screens were canvas objects.
I've recently started doing some stuff in WPF and I came up with an idea to integrate maps into my application. I tried some stuff with Google Maps, but the capabilities aren't that great, so after a while I gave up on Google Maps in WPF.
A little while later I bumped into Bing Maps. This looked way more promising than Google Maps to use with WPF. I've started playing around with Bing's Maps and the capabilities are great!
However, when I tried to put a pushpin on the map it wasn't immediately clear to me how to add a infobox to the pushpin, when hovering over it. I have found some examples how to do so, but it required procedural code linked to the xaml. I was actually looking for a method without using procedural code.
Is it possible to add a infobox to a pushpin with just xaml? Or does anyone have a good alternative method on how to do so?
There is a tooltip property available though, but I wasn't actually looking for that. I was actually looking for Google Maps' pushpin kind of style (if it is available).
Assuming I understand correctly what you want, I believe the short answer is: Sorry, but it's not possible to add a Google-Maps-style info box to a pushpin with just XAML. However, I'll try to help if I can.
Disclaimer: I've been playing with the Bing Maps control for Silverlight, so hopefully this will be applicable to the WPF version of the control as well.
I imagine that you don't want to use the built-in ToolTip either because you want it to look different (i.e. not just a yellow box with text) or because you want it to not disappear when the user moves the mouse away.
If you just want it to look different, I can offer the following. When I specified a template for my Pushpins, I went ahead and used a re-templated ToolTip and allowed the user to click the pushpin to get more information.
Here's the ToolTip template, defined as a StaticResource, which of course could contain anything you want:
<Style x:Key="MyToolTipStyle" TargetType="ToolTip">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border CornerRadius="5" BorderBrush="Black" BorderThickness="2" Background="#5c87b2">
<ContentPresenter Margin="5">
<ContentPresenter.Content>
<StackPanel Margin="5" MaxWidth="400">
<TextBlock Text="{Binding Name}" FontWeight="Bold" FontSize="16" Foreground="White" TextWrapping="Wrap"/>
<TextBlock Text="{Binding Description}" Foreground="White" TextWrapping="Wrap"/>
</StackPanel>
</ContentPresenter.Content>
</ContentPresenter>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
And here's where I used it:
<maps:Map>
<maps:MapItemsControl ItemsSource="{Binding SearchResultsManager.Items}">
<maps:MapItemsControl.ItemTemplate>
<DataTemplate>
<maps:Pushpin Location="{Binding Location}" Cursor="Hand" MouseLeftButtonUp="Pushpin_MouseLeftButtonUp">
<ToolTipService.ToolTip>
<ToolTip Style="{StaticResource MyToolTipStyle}" />
</ToolTipService.ToolTip>
</maps:Pushpin>
</DataTemplate>
</maps:MapItemsControl.ItemTemplate>
</maps:MapItemsControl>
</maps:Map>
Then I'd handle when the user clicked on the pushpin to take them to a details area.
private void Pushpin_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
// Get a reference to the object that was clicked.
var clickedSearchResult = (sender as FrameworkElement).DataContext as SearchResultViewModel;
// Do something with it.
}
However, I imagine you want to keep the ToolTip from disappearing, so that the user can click on controls inside it. Unfortunately, I'm not sure there's a simple way to do that. You might have to define your own custom control, which of course would require some C#/VB code.
Perhaps this new control could derive from Pushpin, and it could show the info box content on mouse-over and/or click. You could use the VisualStateManager to keep most of the code in XAML. The C#/VB would just have to provide a dependency property for the content and some overrides to transition between the visual states at the correct times.
I hope that's at least a little bit helpful!
I have a Canvas element, contained within a ScrollViewer, which I'm zooming using ScaleTransform. However, I want to be able to keep the scroll position of the viewer focused on the same part of the canvas after the zoom operation has finished. Currently when I zoom the canvas the scroll position of the viewer stays where it was and the place the user was viewing is lost.
I'm still learning WPF, and I've been going backwards and forwards a bit on this, but I can't figure out a nice XAML based way to accomplish what I want. Any help in this matter would be greatly appreciated and would aid me in my learning process.
Here is the kind of code I'm using...
<Grid>
<ScrollViewer Name="TrackScrollViewer" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
<Canvas Width="2560" Height="2560" Name="TrackCanvas">
<Canvas.LayoutTransform>
<ScaleTransform ScaleX="{Binding ElementName=ZoomSlider, Path=Value}"
ScaleY="{Binding ElementName=ZoomSlider, Path=Value}"/>
</Canvas.LayoutTransform>
<!-- Some complex geometry describing a motor racing circuit -->
</Canvas>
</ScrollViewer>
<StackPanel Orientation="Horizontal" Margin="8" VerticalAlignment="Top" HorizontalAlignment="Left">
<Slider Name="ZoomSlider" Width="80" Minimum="0.1" Maximum="10" Value="1"/>
<TextBlock Margin="4,0,0,0" VerticalAlignment="Center" Text="{Binding ElementName=ZoomSlider, Path=Value, StringFormat=F1}"/>
</StackPanel>
</Grid>
This is not a purely XAML way of doing it, but there is a very nice piece of work on Joeyw's blog titled Pan and Zoom (DeepZoom style) in WPF with links to the source. He has taken some inspiration from DeepZoom and it gives you smooth/animated panning and zooming of content. And if you're using WPF 4 you could probably modify it a little to add some easing functions to the animations to give it an even nicer feel.
I have to do a "grid" like this:
Harmonic table
I'm trying to create a ListView with ItemsSource="List<Note>" where every odd note in the list is moved on the bottom...
Is the ListView the right control?
How can I draw an exact hexagon with faces that is near next object?
EDIT: hexagon drawing is solved... this is the xaml:
<Path d:LayoutOverrides="None"
d:LastTangent="0,0" Stroke="Blue" Fill="Red"
HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
Margin="0" Width="100" Height="100" x:Name="Path"
Stretch="Fill"
Data="M8.660254,0 L17.320508,5 17.320508,15 8.660254,20 0,15 0,5 8.660254,0 z"/>
The container for your notes would be an ItemsControl or a ListBox if you need to select items. Then you give your items a template using ListBox.ItemTemplate where you include your hexagon drawing. You have a nice tutorial on Custom ListBox layout.
At this point, your hexagons are displayed one below the other as a ListBox does by default. To get your special layout, you have to change the ListBox.ItemPanel. Here you have two possibilities:
either you use the Canvas panel that supports absolute positioning. In this case your items must have X and Y properties that you will use to position them.
or you create a custom Panel, probably based on Canvas, that is able to convert your custom coordinate system (for example note name + octave number) into X and Y. A bit more difficult but much more reusable. An example of Custom Panel on CodeProject.

The key component of a possible solution is a WPF Panel which can arrange hexagonal elements (Standard Panels operate with rectangular child elements). Take a look my HexGrid project (too large to post here). The cental part of it is a HexGrid (WPF Panel which arranges child elements in a honeycomb pattern). Child elements are represented by HexItems (hexagon-shaped ContentControls). There is also HexList (selector ItemsControl which displays items in HexItem container on a HexGrid panel) which gives hex selection support out-of-box.
example of usage:
<hx:HexList Name="HexColors" Orientation="Vertical"
Grid.Row="1"
Padding="10"
SelectedIndex="0"
Background="{Binding Path=SelectedItem.Background, RelativeSource={RelativeSource Self}}"
RowCount="5" ColumnCount="5">
<hx:HexItem Grid.Row="0" Grid.Column="1" Background="#006699"/>
<hx:HexItem Grid.Row="0" Grid.Column="2" Background="#0033CC"/>
<hx:HexItem Grid.Row="0" Grid.Column="3" Background="#3333FF"/>
<!--...-->
<hx:HexItem Grid.Row="4" Grid.Column="1" Background="#CC9900"/>
<hx:HexItem Grid.Row="4" Grid.Column="2" Background="#FF3300"/>
<hx:HexItem Grid.Row="4" Grid.Column="3" Background="#CC0000"/>
</hx:HexList>
