I have a project that is WPF4 (with vb.net behind). I have a window that is full screen, and in the center of it is a grid that is constrained to 640x480 in size. I have five images animated, and the animation should take them off the grid and out of sight. However, the animation shows the image when off the grid (over the window itself.) How do I contrain my animations to stay ONLY inside of the grid?
Grid.ClipToBounds = true;
That should clip the contents within the Grid as it moves past the bounds of the Grid.

I have to crop some control to show only a half of it but the rest should be transparent and clickable so it is not enough to cover the control with something. The result should give a control with only half of the content (for example 50% of top) and the rest should be cropped (not hidden) so some other control below should be visible and not overlapped by cropped part. New control should also scale when window is scaled. How to do this in WPF?
I have finally did the trick using Border around the control and Clip property of this border was set to Multibinging that was generating Rectangle basing on ActualWidth and ActualHeight of my control
Maybe GridSplitter:

Can be used to split views horizontally/vertically, and can be responsive.
A WPF application consists of a uniform grid of arbitrary size. Each cell in the grid contains a canvas. Each canvas is a target for a drag and drop operation.
When I drag another canvas and drop it onto a canvas inside the grid I want the top left corners of the dragged canvas(source) and the target canvas to align, essentially placing the source on top of the target. The behaviour I'm looking for is a snap-to-grid effect.
Currently when I use element.GetValue(Canvas.LeftProperty) the result in NaN. The problem is to determine the position of the corner for a canvas inside the grid, but relative to the entire window. I would prefer to use the grid, as it automatically resize as the window resize.
Is it possible to get the actual position of a canvas inside a grid even when the grid size changed or alternatively specify a canvas to be aligned to another canvas inside the grid?
This problem was solved by drawing each canvas onto another canvas by specifying the top and left properties of the canvas, I had to scratch the grid. I specified the position of every canvas by using
Canvas.SetLeft(Me, position.X)
Canvas.SetTop(Me, position.Y)
where Me is an instance of the canvas.
It is now easy to get the top and left properties of every canvas. The only problem now is I have to implement the resizing of every canvas manually.
I have a WPF window and an Image in a grid in the window. I am animating the Image so it moves from out of view (beyond widow location) into the window.
The animation is nice and smooth and everything works but I notice the image is over top of the window border while it is moving. The image at the end of this question is what it looks like.
Why would the image be over top of the window border, and how do I get it to be "under" the border?
Thanks in advance!
Well after a lot of trial and error it seems the problem was the fact I was moving the image in a grid that had no defined width, so the width would expand over the border when moving the image thus extending the "client" area of the window and showing over the window area.
Once I defined a specific width of the grid, everything worked.
The application will have a menu strip on top and the rest will display lines and shapes. I want to be able to drag and pan the main display area by clicking it and dragging it in any direction.
I am currently drawing items using pixel values (for example a line drawn from (1042,54)to(1240,104). But I think a monitor with a smaller resolution will not be able to display that object. That is why I want to be able to pan the display area.
The lines and shapes are currently being drawn on a gird that I placed inside the window.
If you place the canvas inside a ScrollViewer then if the canvas is larger than the application window it will be displayed with scroll bars.
You can then address points on the canvas with values relative to the canvas rather than the screen.
It gets basicaly to this:
I have a canvas container (x:name="Container" - to reffer later to), with some other controls(e.g. I have a Button 30x60 in size) and I want to scale the Container to fit the button, without having to resize anything. (just using scaleTransform)
If I set a slider binded to the Container Scale, I can slide it to fit the button, but the value is 1.1343 and I want to be able somehow to compute this value programatically, because all the controls inside Container are of different sizes, and resizable in adition.
The question is: is there a way to scale the Container so that a Control from the container is displayed on the entire Container surface? Also the position will have to be adjusted, so that the scrolling vierew of the Container should be positioned over the control, but that is done already.
Thank you in advance,
Daniel
Use Grid as the container. Any control placed inside of the Grid will directly fill the whole Grid, and its size (the width and height) will match the size of the Grid.
It seems when you add a user control using a grid as a container, the usercontrol, which comprises a set of labels and an array of buttons will not align to the top but arranged somewhere in the middle.
