I've done desktop application's GUI for minimum 800x600 pixels. But now I need to make it look good when maximised in any screen size. There is so little to show, I don't know how to adjust the elements in big screen.
Now in 800x600:
Maximised in 1366x768:
I tried to make them bigger with screen size, but that give them kinda ugly, unsophisticated look. What should I do?
You need to use WPF Grid Layout to position your control. It will stretch the size of your control based on the defined layout.
You can read a tutorial here https://www.wpftutorial.net/GridLayout.html
You can use Uniform grid in that case

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.
Given a WPF Application running full screen, a fair amount of controls some of which will animate from off screen to center. I was wondering if there are any special ways to save on the amount of time required to optimize an application for different screen resolutions?
For example, using Blend I've setup some text, which is originally off screen to scroll into view. Now in design mode the start positions are static. If resolution changes the start positions will obviously not be correct.
So I guess to correct this, during app startup. I need to
Check resolution
Move the text box to the desired start location
Adjust the storyboard as required, so the frames all have correct co-ordinates depending on the res of the screen.
I don't mind doing all of this, but if there is an easier way please share!
Thanks
In WPF layout of controls should be made in such way, that when size of window or content changes, controls automaticaly resize/reposition themselves to reflect this change.
This is highly affected how your layout is made, especialy by using specific panels, that do layout of their child elements.
This is also made obvious by using device-independent units for sizes, margins and sometimes positions of controls. And also allows different kind of zooming and scaling of whole UI without any need to redesign the whole thing.
If you are trying to position your controls absolutely, either by using Canvas panel or margins, your are doing it totaly wrong.
In WPF, scene is measured in abstract units, not pixels, and controls are freely scaled. There should be no problems to center something, or what?
I'm trying to size a checkboxlist control to 500,250 from its current 502,251 (It's an OCD thing) but every time I try, it just reverts to 502,251.
Is it because the parent container is docked in the window? Are there any workarounds?
(This is through the visual designer)
Most likely the control is being resized due to the control's font size. The ListControl does not like to display an item that will be "split" by the bottom edge, so it will resize the height. Try changing the control's font size and adjust again to verify.
No work around, and you really do not what one, because the control is really doing the right thing.
Yes, it is OCD. I have it also, but this one you have to let go. :O) Consider yourself lucky because you are only one or two pixels off. I was five pixels off once, and I had to put a note on my monitor to ignore it. It so bothered me.
My developer's box has a screen resolution of 1680 x 1050. I'm developing a full-screen Silverlight 3 application that I'm considering deploying to the Internet. So, I want to make sure the application looks good on a variety of screen resolutions. I just started testing on other boxes, the first one having a screen resolution of 1024 x 768. During the test I found some of the pages on the application were partially truncated. It seems the controls on the page didn't adjust for the lower screen resolution. So, I'm looking for some tips on how to make a Silverlight application, to the extent possible, adjust for screen resolution. For example, are there things one should or should not do on XAML to make adapting to screen resolution easier? Should I just optimize for a minimum screen resolution? Your thoughts and suggestions are welcomed.
You can easily enforce a minimum acceptable resolution by setting the MinHeight and MinWidth properties of your root visual. (Of course, this should be less than the minimum screen resolution to account for browser chrome.)
Try to specify absolute Width and Height only when necessary: for example, for images or icons of fixed dimensions, or for obvious cases like TextBoxes (whose width should reflect the average length of the data entered).
Grid panels are excellent for mixing scalable and fixed layout areas. The star sizing specification takes a bit of getting used to--it's not as simple as a percentage-based proportioning--but it's much more flexible, especially in combination with row/column min/max dimensions.
You don't really need to test on multiple resolutions unless you're interested in testing a range of dots per inch--just resize the browser to approximate different screens. Since there's always a bit of give and take depending on the user's browser configuration, you'll have to account for some variance anyway.
You can make your application scale with the Silverlight Toolkit ViewBox or make it strech with layout controls like the Grid, StackPanel, and WrapPanel. Make your main UserControl have a Width and Height of Auto (or remove the width and height entirely) and the size of the app will resize to the size of the parent div (the default HTML template uses 100%x100%). Then just resize the browser accordingly. IE8 has developer tools that can help you see your app resized to specific screen resolutions.
Testing on a variety of screen resolutions is always a good idea.
I covered the resizing of elements and making it resolution independent on another thread.
You can have a look here, there are multiple ways to sizing and resizing things automatically.
I have a custom canvas that I can drop controls on, move, and resize. I need to be able to at least start with a pre-determined size but then allow re-sizing.
My problem is that I have a user control that doesn't appear to resize. I set Height and Width on the user control (works on drop). But then as the control is resized on the canvas the visual size stays the same (the sizing handles are changing). I can see the Height property changing (usercontrol.height) as the control is resized. But again, the appearance of the control stays the same size.
I had a thought that the inner container on the user control should be bound to the usercontrol.height but that didn't seem to help. (or maybe I didn't have the binding right).
On the same canvas, if the dropped control is for example, an Image control, I can set an explicit height on the drop and everything resizes as it should. So it seems to be UserControl thing.
So is there something special I need to do with UserControls to get the visuals to resize? Should I be using explicit height and width to get it all started?
Thanks for any help.
The WPF layout system can be confusing, as you've discovered. There is no substitute for a solid understanding of the layout and measurement system. If you plan on doing much WPF development, it's worth taking 20 minutes to read this article on the layout system and then experimenting for a while in an iterative environment such as Kaxaml until you feel comfortable.
The system is very logical. It won't take long for the penny to drop. Sorry for the indirect answer, but I don't believe there's enough information in your question to really explain what's going on.
You might also look at the HorizontalAlignment and VerticalAlignment properties.
Not a WPF expert but I believe you need to enable auto-sizing in order to achieve the scenario you are looking for. This is done by setting the Height/Width of a control to Double.NaN which essentially says, "I have no specific size". Once you do that, the control should resize to occupy available space based on the need of the control.
