Gets or sets the ImageSource for the image. public: property System::Windows::Media::ImageSource ^ Source { System::Windows::Media::ImageSource ^ get (); void set (System::Windows::Media::ImageSource ^ value); }; C# To set a menu item's image dynamically, only do the following: MyMenuItem.ImageSource = new BitmapImage (new Uri (Resource/icon.ico,UriKind.Relative));...whereas icon.ico can be located everywhere (currently it's located in the 'Resources' directory) and must be linked as Resource.. If your image source is a stream, use the async SetSourceAsync method of BitmapImage to define the image information from the stream. If your image source is a file referenced by Uniform Resource Identifier (URI), set the BitmapImage.UriSource property, or use the BitmapImage constructor that takes a Uniform Resource Identifier (URI) parameter. The Windows Runtime enforces that a Uniform Resource Identifier (URI) must be absolute; you can't use relative Uniform Resource Identifier (URI) in. The Image element in XAML represents a WPF Image control and is used to display images in WPF. The Source property takes an image file that will be displayed by the Image control. The following code snippet shows the Flower.jpg file using an Image control

Übrigens kannst du es hier auch wie in WPF machen, nur das du zusätzlich ein ms-appx:// vor dem Pfad brauchst: image.Source = new BitmapImage(new Uri(ms-appx:///Resources/Bildname.jpg, UriKind.RelativeOrAbsolute)); So oder so musst du das erzeugte Image-Objekt aber noch in das Fenster bringen PresentationCore.dll Represents an object type that has a width, height, and ImageMetadata such as a BitmapSource and a DrawingImage.

I have folder called images which contains images needed for my WPF app. Now I want to use them as resource from XAML and from Runtime. Is it possible, if yes how (MVVM way) ?

You just need to set your image's build. It's easier to bind the image source in xaml rather then c#. If you must set the image source via code, it too isn't that big of a deal. The image class has the Source property that sets the image, if you set it in the xaml there is a default converter that converts the string your write to the ImageSource. When setting the property through code you need to create the ImageSource instance yourself, the way to do it is as follows WPFで画像を表示する方法をメモ。 Resourcesフォルダを使うパターン. 下記の手順でResourcesフォルダに画像を追加する。 ソリューション エクスプローラーでプロジェクト名を右クリック プロパティを選択 リソースタブを選択; 画像をドラッグ&ドロッ Gerade der Bereich Image.Source wird per code leider gänzlich anders gehandhabt, als per WPF. In WPF reicht es, wenn man den Pfad angibt. Wenn man selbiges per Code probiert also als String wird es schon mal nicht akzeptiert. Sollte man intelligent genug sein und ein URI-Object weiter zu geben ist man schon dem richtigen Ergebnis näher, aber noch nicht richtig. Man muß wie michlG es. You can simply specify the path of the image in the Source property of an Image Element, but to show a different image depending on the value of an enum requires a specific ValueConverter, and you need to be aware that this converter need to convert from the original type to a BitmapImage object, because the Source property of an <image> will not accepts string during binding
To begin, please create a WPF project and drag the Image control to your Window. Now edit the XAML markup for the Image element. Add a Loaded event handler by typing Loaded.

You just need to set your image's build action to Resource in properties, then you can refer to them as normal. a. in code. Copy Code. public Image MyIcon { get { return new Bitmap ( @images\yourImage.bmp ); } } b. in XAML. Copy Code. Icon=Images\yourIcon.ico Using the built in functionality you can easily create a graphical image from any instance of a class derived from the Visual class. The process consists of creating a bitmap first and then exporting it to a common compressed image format like PNG or JPEG. The following blocks conceptually explain the procedure. If you are familiar with the process at that conceptual level, you can proceed straight to the code example at the end

So if your hardware dpi (which WPF gets from the OS) is 120, then the image should be displayed as 120 pixels by 120 pixels, not 96 pixels by 96 pixels. BTW It's actually pretty awesome when you first run a complex WPF app on a 120 dpi system and notice that everything scales up to the same size as it would be on a 96 dpi system. So everything is the right size, just rendered more 'finely. Tooltips, infotips or hints - various names, but the concept remains the same: The ability to get extra information about a specific control or link by hovering the mouse over it. WPF obviously supports this concept as well, and by using the ToolTip property found on the FrameworkElement class, which almost any WPF control inherits from

The Menu control derives from HeaderedItemsControl.It stacks it items horizontally and draws the typical gray background. The only property that the Menu adds to ItemsControl is the IsMainMenu property. This controls if the menu grabs the focus if the user presses F10 or the ALT key If so, then it looks like the new image uses the source's path of the old one (stored in the Tag property) and the picture is actually the same as the one from the removed item. However, this is only a guess and this is why I would ask you to send me a sample project with the reported behavior, if this is possible for you, or simplified code snippets with your implementation [WPF] Fix blurry images 31 January 2014 wpf, xaml This is a very annoying design flaw in WPF: by default, when you include a bitmap image in a view, it appears blurry.
