I am not a real designer and I would like to know if anyone have an idea how can I build the following visual :
The idea is to get 2 rings where inside I will draw secific number of pie represented as "Interactive shape or button". Base on the number of shape, they should cover the whole circle.
In addition to that, I need to be able to interact with each pie shape, and inside and oustide edge of those shape should be a perfect arc based on the circle diameter.
As I am not a perfect designer, how can I represent this visual ?
I was thinking of using a custom panel but then how to draw each panel shape in order that they gets perfect inside and ouside arc and offer interactivity with each of them ?
Thanks for your help
I would appreciate samples as well
Theres actually a Silverlight tutorial on making something exactly like this.
If you didnt want to use that, you could always do it in javascript. Here's an example using Rapheal js
I would recommend looking into WPF Geometry and how you can create custom controls (such as the Circular Gauge Custom Control over on CodeProject) using said Geometry.
I've never created a control quite like what your suggesting, but I would image you would define some form of area that can contain children and style it so that it forms the circular shape you want. Then, adding interactive regions should be as simple as adding controls to standard containers.
Here's a link to a "generic radial panel that can be used to host any items" which subclasses Panel.

Here is the actual shape I want to draw using maybe view style properties or are there any alternatives, thanks
Depending on your needs I would choose something like react-native-canvas they have pretty much everything you gonna need to draw.
Other option would be GCanvas.
With those options you will be able to draw free forms as you wish
But there`s always the option to use SVG as well.
In my past experiences SVG forms solved most of the cases, but sometimes I had to use this canvas libs to draw some more complex or dynamic forms.
Hope this can be of any help to you.
I am working on a project that requires a slider control that corresponds to an image and or a multitude of div objects. The spacing of the slider is irregular (the steps could be [1,4,7,13,14,16...]). Also the steps will correspond to specific spots on an image and or to a specific div object. The perfect slider would be dynamic and re-size with the screen but that may be actually impossible.
The hard part is that I am unable to use JQueryUI, instead I am limited to using controls that work with AngularJS.
I have been looking for hours and cannot find anything that would be a good starting point. So my question is whether anyone has found a good slider control to use with AngularJS?
This one fits some of your criteria

I have a video playing of lines being drawn on the screen. Is it possible to create a pixel shader (for WPF) that turns newly colored pixels a certain color for N milliseconds?
That way, there can be some indication to the user to movement on the screen when the lines don't move often and the user isn't always looking at the screen.
You can use DirectShow. Its written in unmanaged code, so you need to use this wrapper DirectShow.NET in order to use it in your C# application which is running in managed environment (samples are included, even with EVR which stands for Enhanced video Renderer which means MUCH better video quality). And when you will be passing a control handle to wrapper method for setting the video output, you need a WinForms control, because only from them you can get your desired control handle. That WinForms control you can then host in your WPF application using the WindowsFormsHost control provided for such situations when you need to use some WinForms control(s) in a WPF application. Its just theory, so i dont know if its an ultimate solution for you.
BTW: The whole idea is based on fact, that DirectShow is just some query constructed from separated filters. Renderer is a filter (EVR, VMR-7, VMR-9). Sound player is a filter. And they are connected through their pins. Its like a diagram. Electronic schema or something like that. And you can put for example Grey scale filter in there. And voila, video output will be greyscale. There is a bunch of tutorials for that. And completed simple filters as well. Unfortunately, filters must be written in C++:(
PS: I never said its gonna be easy:D
First time working on a GUI project.. and first time doing work on Windows so apologies in advance if this is a really noob question.
I'm taking baby steps into windows programming starting with vb.net WPF. Working in Visual Studio Express 2012.
I'm trying to work out how I can scale all the elements in a window with the window itself.
So for example, I'd create a window, say 1280x720, and place some images in the window. Say one at the top and one in the corner. (this is a basic media based application)
When I resize that window, I want the entire window to scale with it, so image 1 & 2 will get larger if the window gets larger, however this has to happen proportionally so that if I make the window a lot bigger in one direction one image can't overlap the other. Imagine the window is an image and I'm trying to resize it. (The overlap thing is the closest I've gotten to getting this working in my current attempts).
The layout in produciton will be more complex, comprising of mediaelements (video), images, text etc and all must scale accordingly.
This isn't something the user interacts with and so there are no form elements etc, and so I don't need form fields etc to stay the same size throughout scaling. I just need everything to scale like I'm scaling a picture. If for example I displayed this 1280x720 (16:9) layout on a 1920x1080 screen, maximised it should look identical only larger.
Hoping someone can point me in the right direction with this.
What I've tried so far- the few articles I did find on google relating to this (I may well be searching the wrong things) lead me to put all the elements in a viewbox, this lead to the overlap I mentioned earlier.
Ideas ?
I think you could use ViewBox container. The basic idea is as follows: ViewBox scales its content just as if it was an image scaled. This seems to be the closest result to what you've described in your question. Just put a Grid with absolutely-sized columns and rows into the ViewBox and set its Stretch to be Uniform:
<Viewbox Stretch="Uniform">
<Grid>
<..>Your controls, MediaElements, etc
<Grid>
</Viewbox>
You could also combine it (or entirely replace) with (e.g.) Grid Container : it gives you an ability to specify cell width and size usign star-syntax which is similair to html's percent syntax.
Another way is to use the DockPanel.
All-in-all there are plenty ways to achieve something similair and the way to go largely depends on the nuances of your particulair requirements.
Have a look at This tutorial to see a good overview of WPF containers and how to use them.
I'm currently looking to achieve a gradient effect a bit like the rectangle in http://pjnicholson.com/Fireworks/fillgradients.htm
If I compromise a little I can get close to this using RadialGradientBrush... but is there any (not too painful) way to achieve the rectangular effect?
Use an ImageBrush instead and use this image (or a similar image generated using some image editor) for the background of your rectangle.
One solution a colleague and I came with was to derive a new Panel that used a WriteableBitmap as the source for its background.
The panel will give you the dimensions you need to make your WriteableBitmap. Using whatever algorithm you want you can fill it appropriately. In our case, we needed a radial or cone gradient, but the same concept applies.
Additionally, you can create several properties on your new control to specify the colors for the gradient. We adapted a LinearGradientBrush for our needs, but if you're working on just two colors, simple properties may suffice.
I don't have the code handy but will try to find it and post an update later. But the above should get you going.
