I have a panel withing a WindowsFormHost in a WPF app. Eventually i need to be able to click and draw points. I had it working fully in a separate WinForm form... but for some reason the paint event won't fire at all when Invalidate() is called! The click event is definitely firing as the message box comes up on the click. Not a peep out of the paint even though. Can't figure out why for the life of me... here's the code.

private void wfSurface_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Graphics g;
g = wfSurface.CreateGraphics();
epanet epa = epanet.GetInstance();
SolidBrush s = new SolidBrush(System.Drawing.Color.Blue);
g.FillEllipse(s, Convert.ToInt32(epa.xCord), Convert.ToInt32(epa.yCord), 50, 50);
g.FillEllipse(s, 400, 400, 500, 500);
MessageBox.Show("paint event fired");
}
private void wfSurface_MouseClick(object sender, System.Windows.Forms.MouseEventArgs e)
{
epanet epa = epanet.GetInstance();
epa.xCord = e.X;
epa.yCord = e.Y;
MessageBox.Show("xCord is: " + e.X.ToString());
wfSurface.Invalidate();
}
Edit:
And to further check that the paint event is the issue I added the line g.FillEllipse(s,400,400,400,400); into the click event and it successfully drew the ellipse.
Not much of a WPF guy, but my guess would be to add this:
<WindowsFormsHost.Child>
<wf:Panel x:Name="wfSurface" Paint="wfSurface_Paint"
MouseClick="wfSurface_MouseClick"/>
</WindowsFormsHost.Child>

Hello I am currently using library Mahapps but I have some problems. How can I pop out the flyout when clicking the "Menu 1" MenuItem? I tried with the following code but it did not work.
<ListBox.ContextMenu>
<ContextMenu>
<MenuItem x:Name="FlyoutOverview" Header="Menu 1" IsCheckable="True" Click="flyoutOverview">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="GlobeWire"/>
</MenuItem.Icon>
</MenuItem>
<Separator/>
<MenuItem Header="Menu 2"/>
<Separator/>
<MenuItem Header="Menu 3">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="People"/>
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Menu 4">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="UserDelete"/>
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Menu 5">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="ControlResume"/>
</MenuItem.Icon>
</MenuItem>
</ContextMenu>
</ListBox.ContextMenu>
</ListBox>
If you have followed the tutorial links I provided then I suppose you are able to create a simple View and its ViewModel.
The View can be a Window and has its Grid content like this:
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Controls:FlyoutsControl Grid.Column="1">
<Controls:Flyout x:Name="yourMahAppFlyout" Header="Flyout" Background="AliceBlue" Position="Right" Width="350"
IsOpen="{Binding ElementName=FlyoutOverview, Path=IsChecked}">
<TextBlock Text="My Flyout is here" />
</Controls:Flyout>
</Controls:FlyoutsControl>
<ListBox Grid.Row="0" Grid.Column="0" ItemsSource="{Binding NameList}">
<ListBox.ContextMenu>
<ContextMenu>
<MenuItem x:Name="FlyoutOverview" Header="Menu 1" IsCheckable="True"
IsChecked="{Binding IsMenuItem1Checked}">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="GlobeWire"/>
</MenuItem.Icon>
</MenuItem>
<Separator/>
<MenuItem Header="Menu 2"/>
<Separator/>
<MenuItem Header="Menu 3">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="People"/>
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Menu 4">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="UserDelete"/>
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="Menu 5">
<MenuItem.Icon>
<iconPacks:PackIconModern Kind="ControlResume"/>
</MenuItem.Icon>
</MenuItem>
</ContextMenu>
</ListBox.ContextMenu>
</ListBox>
</Grid>
The ViewModel can have these properties:
public MainWindowViewModel()
{
NameList = new ObservableCollection<string>()
{
"John", "Micheal", "Jack"
};
}
public ObservableCollection<string> NameList { get; set; }
public bool IsMenuItem1Checked
{
get { return _isMenuItem1Checked; }
set { SetProperty(ref _isMenuItem1Checked, value); }
}
The first menu item in the listbox binds its "IsChecked" property to "IsMenuItem1Checked" in ViewModel, and FlyOut "IsOpen" property binds to "IsChecked" of that menu item.
I am trying to build application which has some pictures drawn on buttons. Application looks nice on Windows 7 - as expected, although on Windows 10 it looks differently.
Despite Defined width and height size, image is truncated.

Thanks for any advice.
You should check this article before trying anything. It's all about the theme difference between win 7 and win 10.
https://arbel.net/2006/11/03/forcing-wpf-to-use-a-specific-windows-theme/
There is another workaround from Visual Studio.
You click with the mouse on the MenuItem and you look at the Template in the Property Inspector under the Miscellaneous group.
Then you "Convert to New Resource..."
see the image
so you will get the corresponding xaml transformed as
<MenuItem Command="{Binding YourCmd}" Header="Your Header"
Template="{DynamicResource MenuItemControlTemplate1}" >
Then you can build on your Windows 7 machine and deploy to Windows 10 without such issue.
The icons in my menu are showing in the design view but not at runtime.
Why?
I have tried both with and without pack://application :,,,

<Grid Name="grid_Main">
<Menu IsMainMenu="True" x:Name="menu" DockPanel.Dock="Top" HorizontalAlignment="Left" Height="auto" VerticalAlignment="Top" Width="{Binding ElementName=grid_Main,Path=ActualWidth}">
<MenuItem Header="File">
<MenuItem Header="Exit" >
<MenuItem.Icon>
<Image Source="/Aurora4XHelper;component/Resources/Icons/Exit.png" />
</MenuItem.Icon>
</MenuItem>
</MenuItem>
<MenuItem Header="Design">
<MenuItem Header="Missile">
<MenuItem Header="Missile">
<MenuItem.Icon>
<Image Source="pack://application :,,,/Aurora4XHelper;component/Resources/Icons/Missile.png" />
</MenuItem.Icon>
</MenuItem>
<MenuItem Header="MIRV" />
<MenuItem Header="Bouy" />
<MenuItem Header="Mine" />
</MenuItem>
<MenuItem Header="Sensor" />
<MenuItem Header="Ship" />
<MenuItem Header="Terraforming"/>
</MenuItem>
</Menu>
</Grid>
Try to remove the /Aurora4XHelper;component/ part and just put <Image Source="Resources/Icons/Exit.png" /> instead.
Also make sure the BuildAction of the png file is set to Resource.
Ok so I have a grid that holds the menubar then in that grid I have a scrollviewer that holds another grid. If I put lets say a label on the most inner grid (one with scrollviewer) out of view all down vertically the scrollviewer cannot scroll so I can see it for some reason.
I set max heights for the scrollviewer and grid... and also added a button that we cannot scroll to.
<Grid Background="#FF1C1C1C" Margin="0,0,0,-1" Width="1160" ScrollViewer.CanContentScroll="True" MinWidth="1160">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="55*"/>
</Grid.ColumnDefinitions>
<Menu HorizontalAlignment="Left" Height="19" VerticalAlignment="Top" Width="1150">
<Menu.Background>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="#FF343333" Offset="1"/>
</LinearGradientBrush>
</Menu.Background>
<MenuItem Header="FILE" Foreground="White">
<MenuItem Header="Open Accounts.txt" HorizontalAlignment="Left" Background="#FF1C1C1C"/>
<MenuItem Header="Exit" HorizontalAlignment="Left" Width="187" Background="#FF1C1C1C"/>
</MenuItem>
<MenuItem Header="SERVER" Foreground="White">
<MenuItem Header="Start" HorizontalAlignment="Left" Width="145" Background="#FF1C1C1C"/>
<MenuItem Header="Close" HorizontalAlignment="Left" Width="145" Background="#FF1C1C1C"/>
</MenuItem>
<MenuItem Header="VIEW" Foreground="White" Background="#FF1C1C1C">
<MenuItem Header="Client Manager" HorizontalAlignment="Left" Background="#FF1C1C1C"/>
<MenuItem Header="Search Utility" HorizontalAlignment="Left" Width="171" Background="#FF1C1C1C"/>
<MenuItem x:Name="DebugLogButton" Header="Debug Logger" HorizontalAlignment="Left" Width="171" Background="#FF1C1C1C" Click="onDebugLogClick"/>
</MenuItem>
</Menu>
<ScrollViewer Opacity="0.1" VerticalContentAlignment="Stretch" Margin="0,0,10,0" MinWidth="1150" MaxWidth="1150" Width="1150" MinHeight="600" MaxHeight="1500">
<Grid Width="1118" MinWidth="1118" MaxWidth="1118" MaxHeight="1500">
<Button Content="Button" HorizontalAlignment="Left" Margin="542,2479,0,-1890" VerticalAlignment="Top" Width="75"/>
</Grid>
</ScrollViewer>

I have resolved it.
The issue is improper use of Grid I now know that I need to make a row definition for the scroll viewer.
I'm working with a WPF menu and unfortunately whenever I go to set an Icon in Visual Studio designer I receive an exception error.
To work around this I'm trying to set the icon with XAML code, I have the following:
<Menu Height="23" Name="menu1" VerticalAlignment="Top" BorderThickness="0" SnapsToDevicePixels="True" OverridesDefaultStyle="False" Opacity="1">
<MenuItem Header="Help">
<MenuItem Header="About">
<Image Source="Images/Help.png" />
</MenuItem>
</MenuItem>
</Menu>
Unfortunately this creates the following scenario:
I've tried googling the issue but can't see where my XAML has gone wrong. I know this is simple, but I'm stuck!
Is this what you want?
<Menu Height="23" Name="menu1" VerticalAlignment="Top" BorderThickness="0" SnapsToDevicePixels="True" OverridesDefaultStyle="False" Opacity="1">
<MenuItem Header="Help">
<MenuItem Header="About">
<MenuItem.Icon>
<Image Source="Images/Help.png" />
</MenuItem.Icon>
</MenuItem>
</MenuItem>
</Menu>
do you want something like this?
<Menu Height="23" Name="menu1" VerticalAlignment="Top" BorderThickness="0" SnapsToDevicePixels="True" OverridesDefaultStyle="False" Opacity="1">
<MenuItem Header="Help">
<MenuItem>
<MenuItem.Header>
<StackPanel>
<Image Source="Images/Help.png" />
<TextBlock Text="About" />
</StackPanel>
</MenuItem.Header>
</MenuItem>
</MenuItem>
</Menu>
