I'm building a form with two layers of controls. The bottom layer is a set of Panels with defined properties, one of which is a color different from the form background. The top layer is a set of picture boxes I'm using to display a circle. I've set the PictureBox Background to Color.Transparent, and I've offset it from the underlying Panel by one pixel to get the form to draw the underlying Panel. However, the area around the circle in the PictureBox is displaying the Form Background color, not the panel color. I don't want to draw the circle in the Panel, because I want the circles to move between Panels, and actually look like just a circle that's floating across the form independent of the Panel board underneath. Think of the effect as moving a piece on a board game (you see the peg move across the board, possibly on a diagonal not following the normal game path, then stop in a place on the game).
How can I get the PictureBox to have the underlying Form and panels show through, not just the form background color? I'm using C# Visual Studio 2010, and I'm not a terribly experienced programmer, so a code example would be helpful. An image of the form is at:

Found a way around the problem. I got rid of the Panels for the spaces in the game, and instead drew them as rectangles on the form's background image.

Need a quick suggestion for styling a WinForm. I made it with rounded corners even when re-sized. Now trying to add a close button with a image (ControlBox=false), overlapping or clipped to top right corner. This is what I could end with.
But I wish to make it more like in this example image.
How could I achieve this in WinForm.
Here's the trick : your window doesn't just end with the white part. It extends a little bit further. The close button comes under the 'extra' part. The other sides where the window appears to not be there is actually transparent...or in the case of the image, semi-transparent.
The glow effect is provided by the window. Set the TransparencyKey property of the window to Color.Magenta (its a convention as Magenta is the color least likely to be used in a window). Then set the background image to a white background with a little bit of Magenta in the edges. The Magenta will appear transparent when set as the background image.
Fiddle around with TransparencyKey and you'll understand what I mean
Winforms itself cannot provide this for you without outside manipulation of the windows,
because it still uses win32 windows classes in the background.
If you want transparancy in windows: see articles like:
Cool, Semi-transparent and Shaped Dialogs with Standard Controls
And the method in Win32 to do it:
SetLayeredWindowAttributes
I've been searching for awhile, but haven't been able to find anything. I'd like to be able to add kind of a glimmer or sparkly animation on an image element in wpf.
Essentially the effect here I'm after here is the same that you get with trading cards that are "foil's".
I'd like to have an image, and then be able to add this animation to it at will. I'm thinking maybe some kind of user control, or template possibly. Hopefully generic enough that I can just toss an image at it and it will just overlay the image and run.
Any ideas?
A simple construction that easily can be turned into a control is by nesting the image in a Grid and adding a second Grid (on top) as a sibling.
De second grid can be given a linear gradient brush that is primarily transparent but does contain a white glimmer.
This brush can be animated; you could move it and change the opacity of the grid/brush.
This way you do not change the image.
I have an application with a small overview window to navigate the canvas faster. On that window I display a flowchart with relations and decisions , etc... When the flowchart grows the overview window doesn't display the line's anymore this is because the line thickness is less then 1 px.
I've already tried to set the snap to device pixels on the lines,the canvas with the brush on it,but without success.
Is there an option to make the brush display the lines even if they are less thin then 1 px?
If I understand you correctly, you have essentially a minimap to navigate your Window. In which case, have a look at rendering controls as bitmaps: http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.rendertargetbitmap.aspx
It should be pretty simple to render your canvas and display it in the overview window.
I want to create a custom splash screen where some text on the page will end up being the progress bar. I need the text to flood fill with color from left to right based on the % loaded. My first thought (since I'm not use to doing this type of UI related stuff) was to have a textblock with the forecolor being trasparent layered over something like a border with its backcolor set and then grow the border control based on the %, but this is such a hack, there has to be something better with all the wonderful things silverlight can do. I had also thought about using a image so I could outline the text, but noticed the image was slow and was the last thing to load on my splash screen.
Any ideas on the right way to acomplish this?
I'm developing a multi track video player in wpf and need to be able to copy the video that is playing in one grid layout of the main window into a seperate window that will go out of a projector. The videos are loaded and drawn onto rectangles using drawing brush and are added to a grid. I can't call clone on the rectangle, or the grid, or the canvas, so I'm currently resorting to copying the drawing brushes, passing them through to the otherwindow class and reassigning them to newly drawn rectangles.
However, this gets even worse as I'm 'cross-fading' between two video by drawing another rectangle with a new video in front, then changing the opacity value of the front video to gradually block out the one behind. So I now have two brushes on two rectangles tied to storyboards to animate, and I'm having to pass everything through and basically compute everything twice.
Is there any sensible way of doing this? I'd love to be able to literally grab the pixels from one area of the main video and display them in the second window, but everything seems abstracted away.
Any suggestions would be a massive help
Have you looked at VisualBrush?
