I set window icon property in xaml code or in the properties window correctly in a very simple wpf application, but visual studio always throws an XamlParseException at runtime. Why is this happening?(using visual studio 2013 and windows 8, my icon size is 15 KB)
<Window x:Class="WpfApplication1.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" Icon="pack://siteoforigin:,,,/Resources/MyIcon.ico">
<Grid>
</Grid> </Window>
<Window x:Class="WpfApplication1.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" Icon="/Resources/MyIcon.ico">
<Grid>
</Grid> </Window>
It is a problem with your image Build Action Property, check the arrows for further info..

My application works with main window and user controls for every view.
the main window have default size.
I want that one of the user controls will change its size when entering the view.
when i change the size with local it changes the user control and not the width and height of the window.
Main window :
<Window x:Class="EEPromTool2.View.MainMenu"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:viewmodels="clr-namespace:EEPromTool2.ViewModel"
xmlns:views="clr-namespace:EEPromTool2.View"
xmlns:local="clr-namespace:EEPromTool2.View"
Background="#191919"
WindowStyle="None"
ResizeMode="CanResizeWithGrip" AllowsTransparency="True"
mc:Ignorable="d"
Title="EEPROM Tool" Height="680" Width="1000"

User control :
<UserControl x:Class="EEPromTool2.View.Revision"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

Thanks for any advice.
I am trying to use a MVVM pattern instead of putting all logic in the code-behind file, but I can't seem to get it working.
My view is this:
<Window x:Class="WpfApp4.MainWindow"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApp4"
mc:Ignorable="d"
xmlns:vm="clr-namespace:WpfApp4.ViewModel"
Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
<vm:ViewModelMain />
</Window.DataContext>
<Grid>
</Grid>
And this is my ViewModel:
namespace WpfApp4.ViewModel
{
class ViewModelMain
{
}
}
What am I doing wrong here?
Visual studio can be a bit temperamental sometimes with xaml warnings and errors. Try closing the window, and/or cleaning and rebuilding the project, or if all else fails close all windows and restart visual studio
How can I get XAML code of a window as a string, change this string, and upload this string as a xaml-code of window?
For example, I have
<Window x:Class="WpfApplication1.MainWindow"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ComboBox Margin="0,0,9,38" Name="button1" Height="82" HorizontalAlignment="Right" VerticalAlignment="Bottom" Width="132"></ComboBox>
</Grid>
</Window>
and I want to have this xaml code in the end
<Window x:Class="WpfApplication1.MainWindow"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ComboBox Margin="0,0,9,38" Name="button1" Height="82" HorizontalAlignment="Right" VerticalAlignment="Bottom" Width="132">
<ComboBox.ItemTemplate>
<DataTemplate>
<local:d_dddw_imp_insurance_list />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
</Grid>
</Window>
If your using wpf/xaml with c#, visual studio generally compile the xaml code to c#, to be as performant as possible. If you want to have some dynamic XAML, you need to use XamlReader to read xaml and display at "on your own".
Just take a look at: Loading XAML XML through runtime
Than you can change or manipulate the xaml and display the result very easily.
I have code similar to the following:
<Application
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Software_Suite_Maker"
xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" x:Class="WpfApplication1.App"
StartupUri="MainWindow.xaml">
<Application.Resources>
<FontFamily x:Key="FontFamilyName">./Fonts/#Segoe UI</FontFamily>
</Application.Resources>
and the Window xaml code is:
<Window x:Class="WpfApplication1.MainWindow"
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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WpfApplication1"
mc:Ignorable="d"
Title="MainWindow" Height="350" Width="525">
<Grid>
<TextBox FontFamily="{StaticResource FontFamilyName}" Margin="135,122,187,180" Text="test"/>
<Button FontFamily="{StaticResource FontFamilyName}" Margin="135,144,329,154" Content="test"/>
</Grid>
Now I want to change the value of FontFamilyName from behind code. I wrote this code:
var font = TryFindResource("FontFamilyName") as FontFamily;
font = new FontFamily("./Fonts/#Tahoma");
But nothing happened and did not change.
My question is: How can I change FontFamilyName value from behind code and changes will also be made on the objects?
You have to use a DynamicResource for that :
<TextBox FontFamily="{DynamicResource FontFamilyName}" Margin="135,122,187,180"
Text="test"/>
<Button FontFamily="{DynamicResource FontFamilyName}" Margin="135,144,329,154"
Content="test"/>
Read on MSDN about DynamicResource:
Provides a value for any XAML property attribute by deferring that value to be a reference to a defined resource. Lookup behavior for that resource is analogous to run-time lookup.
Hello:
I have been experimenting with WPF this afternoon, Im wondering does anyone know how I can manually enable resizing ? I have my main windows set with the following properties which removes the close/min/max and resize;
<Window x:Class="WpfApplication1.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" AllowsTransparency="True"
WindowStyle="None" Background="Maroon" ResizeMode="CanResize">
</Window>
I have found how to add my own close/min/max buttons but have not found how to enable resizing.
ResizeMode="CanResizeWithGrip"
