My goal is to attach a new image control while the application is running.
img = new System.Windows.Controls.Image();
img.Margin = new Thickness(200, 10, 0, 0);
img.Width = 32;
img.Height = 32;
img.Source = etc;
I've tried
this.AddChild(img);// says must be a single element
this.AddLogicalChild(img);// does nothing
this.AddVisualChild(img);// does nothing
It was never this difficult to add a element with forms. How can I simply attach this new element to the main window (not another control) so that it will show up.
Solved it, I named the grid main, and from there I was able to access the children attribute and the add function
main.children.add(img);
<Window x:Class="Crysis_Menu.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded" AllowsTransparency="False" Background="White" Foreground="{x:Null}" WindowStyle="SingleBorderWindow">
<Grid Name="main">
<Button Content="Run" Height="23" HorizontalAlignment="Left" Margin="12,12,0,0" Name="btnRun" VerticalAlignment="Top" Width="151" Click="btnRun_Click" />
<TextBox Height="259" HorizontalAlignment="Left" Margin="12,40,0,0" Name="tbStatus" VerticalAlignment="Top" Width="151" />
</Grid>
</Window>
You should have only one root element under window. Adding the image using this.AddChilda adds the image as child of window, but you probably have some other child defined(Grid for example). Give a name to this child (Grid in the example) and then in the code behind add the image to the Grid
Example :
<Window>
<Grid x:Name="RootGrid">
</Grid>
</Window>
Then in the code behind use
RootGrid.Children.Add(img);
