I have a window with a number of controls upon it, each control with a Tooltip associated. In an effort to jazz up the window a little, I have overlayed some semi-transparent ellipses which gives the whole window a glossy finish, however, in some cases the positioning of these ellipses are preventing the hit-test getting down to my controls.
How can I have the ellipses visible, but transparent from a hit-test point-of-view?
IsHitTestVisible = false

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.
I need a ScrollViewer for WPF application which like on some web pages (like Facebook), scroll bars are hidden even if content is long, but when mouse is over bars become visible. Anyone have idea how to do that?
Tnx.
MVVM focused answer:
I'm sure there is a property which allows you to hide or show the scroll bars.
Bind this property to your ViewModel.
Create a MouseOver event which fires when the mouse moves into a certain part of the screen. To do this, you could overlay an invisible grid over the screen, with the right hand 10% as the target area.
Now when the mouse enters the region, show the scrollbar, and when it exits the region, hide the scrollbar.
Ensure that you set the MinWidth on the invisible region, so that if the window gets narrow, the scrollbar trigger area is still wide enough to be usable.
I have a set of User Controls, derived from FrameworkElement. Each host one or more DrawingVisuals. These drawing visuals can represent text, graphics, progress meters etc and are used to display the states of various HMI devices.
These, appearance-wise work fine in a grid - images are rendered, text and backgrounds appear fine, dependency properties can be set. However, when I encapsulate them in a Canvas, they disappear all but for the drawing visuals representing labels. And even for these, only the text rendered by DrawingContext.DrawText is visible. Operations performed by dc.DrawImage, cd.DrawRectangle etc do not appear.
Can someone please shed some light on why this might be.
Thanks
Are you positioning your controls properly? In a grid you have margins for each item, where as in a canvas you have to set Canvas.Top and Canvas.Left for each element. Is it not that those items are hidden underneath something? Try using snoop to use if the controls are actually part of Canvas children or if they have not been added at all.
You can read more about Canvas on MSDN
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.
In WPF window, I have specified SizeToContent="WidthAndHeight".
I have a number of panels stacked up, of which I change the visibility (to Visible or Collapsed) as required. My window resizes itself according to the panel that I have set visible. No issues here.
My problem is with the resizing, that the window resizes with a jerk to the final size.
I want to animate this such that the resizing is smooth. And i want to do this in my XAML file.
Is there any solution for this???
P.S. - I have not set any Width or Height property in the window and I want to restrict myself from doing that.
