i have a PictureBox in my Windows Form application and i am in the process of converting my application to Silverlight and i would like to know what is the alternative of PictureBox in Silverlight, Thank you!
Depending on the functionality of the PictureBox you are using, you could just use the Image control in Silverlight.
Image control is your only choice for this case, but you should be careful that this control just support .jpg and .png image extentions and for other formats you must create or use converters
What you might want to try is the Viewbox control. Then, inside of the Viewbox you can place an image. The great thing about the Viewbox is that you can always scale everything inside consistently, even as the VB resizes. Or, you can use the Image as #Chris pointed out and provided size limits and a scale setting.
Sample XAML:
<Viewbox x:Name="vb">
<Image x:Name="myImage" Source="pathToImage"/>
</Viewbox>
You could then place the Viewbox inside a Stackpanel or Grid to achieve proper layout. Hope this helps!

I am coding a sketching interface using UWP inkcanvas. Basically, I need to provide feedback to the user's drawings, like checking stroke correctness, shape beautifulness etc.. I am thinking about providing interactive feedback directly on the ink canvas, using arrows, auxiliary lines to highlight the difference between the input and a template. The best way I can think of is to add extra shapes to inkcanvas, just like using drawLine in JPanel. But I kind of figured out that strokes is the only acceptable format in UWP inkcanvas. I am wondering if there is still any way I can use to achieve this goal?
Thanks in advance.
InkCanvas is not suitable for drawing something programmatically I believe. The easy way is ... just overlay the canvas like following,
<Grid>
<InkCanvas x:name="myInkCanvas" />
<Canvas x:name="myOverlayCanvas" />
</Grid>
and draw your shapes to the myOverlayCanvas.
Using WPF, I need something like Canvas, but with the option that elements are sized in relation to the canvas. I'm displaying an Image and multiple Rectangle elements and would like to have the image as well as the rectangles sized when the container is resized. Using a Canvas, the elements always retain the original size.
The answer is to use a ViewBox around your Canvas. Try this:
<ViewBox>
<Canvas>
<!-- Your elements -->
</Canvas>
</ViewBox>
You should set the Stretch and StretchDirection properties according to your needs. The ViewBox will scale all UI elements inside equally. Please see the first linked page on MSDN for further help with this class.
You are looking for ViewBox. And yes, it's a short, but an answer =P.
i'm fairly new at this so i apologize in advance if i say anything stupid.
I am making a UI in WPF that consists of 8 buttons to open various programs set on my computer. Currently i am trying to get the buttons in the UI to scale based on the detected window size.
The problem i am having is trying to get the calculations done in the C# code to link over to the scale transform option for the buttons in XAML.
I have searched high and low to find a solution but i still cannot find a way to link the value to XAML. Does anyone know of a guide for something like this and should it be done using a converter?
Thanks for any help.
When you need your content to autoscale, put it all into a ViewBox control.
<Window>
<Viewbox>
<Grid x:Name = rootGrid>
</Grid>
</Viewbox>
</Window>
Now everything will magically fill to the window size and scale! Instant awesomeness for your app.
I have a Grid control which contains a Viewport3D amongst some other things and I would like to have a "live preview" of this Grid's contents drawn in another control using WPF. Can anyone tell me the best/fastest way to do this? :)
In an ideal world I'd like to avoid serialising to a bitmap and copying the buffer manually since the Grid control has a large resolution.
Thanks in advance!
A VisualBrush is what you are looking for.
And for Hittesting, this should be helpful.
I need to get the background image of a Panel that's on another form. I'm using this as a texture in a DX application. I cannot use "CopyFromScreen" as any other control that is over the top will be included in the captured image. Maybe one approach would be to make a copy of the Panels Background bitmap into memory to share with the other app - don't know how to do this in C#.
Or is there some GDI method?
Many thanks in advance.
You can use objPanel.DrawToBitmap() function it will give the whole this what is on panel.
Have you checked Panel control to see if it has any properties that can return you the background image in bitmap format?.
