Is it possible to create a UI controller that would look like a home screen? Or is there one already?
I am trying to make one using a Grid controller, but I am struggling with sizing - I could not find exact sizes for tiles, margins, only for their content, and it appears that margins and tile sizes change on over-scroll.
I would like to use this to display something like a picture album.
Your answer for photo album is WrapPanel.
One of the new controls in the Silverlight Toolkit is WrapPanel. It enables users to position child elements sequentially from left to right or top to bottom. When elements extend beyond the panel edge, they are positioned in the next row or column.

I have a UWP app that I am working on, and using absolute position creates problems when using the app on screen sizes different than the one it was designed for.
I'm not sure how exactly i should place elements at distances from each other without using margin and absolute position. How should I be doing this?
Edit: I am using XAML to design the UI.
Well, it depends on what UI you want to build up.
There are various panels and, usually, there is NO need to use absolute position in most cases.
Usually, the Grid panel is used to create flexible layouts, by adding rows and columns: for example, if you want to create a page with some content and a bottom app bar with buttons on it, you usually create a Grid with as many rows as you need for your content controls, plus one for the bottom appbar itself.
Years ago, I also started building UIs by using absolute position for every element, but then times passes and you start having a flexible mind in order to build flexible layouts.
Sorry to not answer any further, but your question is just TOO broad to give any precise answer.
Best regards
How do you properly position elements in XAML without using absolute position?
You should use an appropriate layout panel:
Layout panels are containers that allow you to arrange and group UI elements in your app. The built-in XAML layout panels include RelativePanel, StackPanel, Grid, VariableSizedWrapGrid, and Canvas.
below i attached an app help guide screen. I am understanding how to build this screen.
If any body have idea please share here
View with semi transparent background color (backgroundColor:"rgba(0,0,0,0.5)";) and some images on top of it.
So, using images is bad. You'll need images for translations and if you do this as one image you'll need to ensure all devices are covered so your arrows point to the right element.
Minimise images == smaller app.
First thing you'll need to do is a create a blocker view -- so that's a view that will fill the screen and have a black background with opacity.
You can't apply that to the window as everything in it will be semi-transparent so:
Create a transparent Window that fills the screen.
Add to that window a view that fills the window and has opacity say 0.5 and black background
Add to the Window (not the view you just created) the other elements and button -- ideally, these should be individual graphics of the arrows, sized in such a way that you can position them based on the host element (the item they are pointing to / referring to). Use real text so you can handle translations / reduce file size.
So you'll need a way to associate each tip with a control they are anchored too, and that will ensure that regardless of the screen size, the tip will appear in the correct place.
First of all, always give a try before putting questions anywhere because it makes you learn things on your own for long time.
The easiest step for you to do this is to ask your designer to create a complete image just like that & you just have to show it on top.
If you have to show that image in different translations, then you can ask your designer to provide you required translations images.
I'm trying to create a live tile for my application, using a user control.
The user control contains a grid, an image and a rectangle filled with color.
Now here comes the funny part.
I want the rectangle to act as a background for the tile's title, and the image to fill the rest of the tile. And i said to myself, well, lets put some rows in that grid and set the like you usually set them in a WPF/SL application.
I then write the entire thing in a WBM and save it to isostore.
The problem is, the parser seems to ignore the presence of grid's rows. regardless of what I try, the rectangle is not shown, and the image covers the full tile, when it should only cover the first row. It is as if the grid didn't even existed.
Another funny aspect is that it doesn't matter if I use rows or columns, the result is the same.
Any ideas?
Are you using the following method?
Dynamic LiveTile - adding background image?
I recently implemented a Live Tile using a Grid with Rows and Columns for layout of some TextBlocks. I encountered similar challenges, so I placed the control that I was using for my Live Tile on a blank page in my app to better see what was happening. Does the control render correctly when displayed on a page (versus being rendered to a WriteableBitmap)?
Another idea. Instead of trying to position the Rectangle relative to the tile's Title, why not leave the Title property blank and put the same text in a TextBlock within the user control?
If you are careful about the font and positioning of the TextBlock, the text on the resulting background image can appear indistinguishable from text displayed from the Title property. I decided to follow this strategy myself. I found the font information in the following answer:
Font size and family for a tile's title
Otherwise, could you post an example of the XAML you are using?
I'm trying to make an animation effect similar to the one on Safari(iPhone) when you add an element to the reading list. It's similar to the one that appears when starting to download an item from App Store application: the application item drops to the dock to start downloading.
First it bounces up and then goes to the dock. It's a very nice effect that Apple uses on their OS.
I have an image view on screen that I want to drop with this kind of animation to my toolbar in my application.
If there is someone who did it or know what's the name of the effect, could please tell me how to do it.
Thank you.
"Add to reading list" shows no animation on my phone but of your description it sounds like the "Open in background"-animation in Safari (iPhone). My answer describes that animation.
I wrote a thing like that a few months ago and much of it is doable while some of it is not. Your questions showed me that more people are to know how it is done so I wrote a blog post about it. I will describe the high level approach and challenges here but you can read more about it in that post.
Getting to content to animate
If you choose to animate the view that is on screen down to the (in your case) tool bar then you will only have to access its layer. If you want the original view to remain and animate a visual copy (like the "open in background"-Safari animation) down to the bar item then you should create a new layer and draw the content of your layer into an image and set that image as the content of the layer that you are animating
Calculating the end position
The start position of the animation is simply the frame of the view. The end position is very tricky since bar items (both tool bar items and tab bar items) are not UIView subclasses and doesn't have a public view property. This causes problems when you want to shake the bar item later on.
I decided to make a visual approximation of the end position using some simple heuristics. If you know before hand that you will only animate to a single bar item then the end position can be hard coded to a suitable frame.
Animating along a path
There is nothing special to moving, scaling and rotating the layer from the start to the end position. If you want to read more about how I did it you can look at the post I wrote.
Shaking the bar item
This cannot be done without a lot of custom code or using private API at the moment. Since bar items doesn't have a view or a layer there is no accessible layer for you to animate. I guess that you could have a custom animating image that does the shake and set that during the animation and set the new image afterwards. The approach of drawing into an image and animating that doesn't work that well either since there is no accessible layer who can draw its content into the image (you want this for the special effect of the tool bar item and tab bar item).
...put all this together and tweak it to your special needs and you will have an animation that resembles the animation you are looking for.
Does someone have an "easy way" to make a view like camera roll app? I need to display miniature photos (buttons) and push new views from them. I don't know how to display miniature images in a scroll view. The number of miniatures is large, so they don't fit the screen, and I think UIScrollView is the only solution.
Check out TTThumbsViewController, part of Three20; this should pretty much do what you want (and it's open source if you need to change it).
A scroll view really just controls the visible region of a single content view. If you want a grid of small images, you'll need to create a view that contains a number of image views or otherwise displays the grid of images. Make this the content view of the scroll view. Also, it'd be a good idea to construct your image grid view such that it only loads and draws the images that are visible, particularly if you're going to display a large number of such images.
