Im trying to figure out how Grid does with size-sharing in their columns and rows. Im looking at the Grid-code with Reflector but can't find any hits. The cols/rows sharing size should first get a desired size and then be measured again with the max found size to get the same size to avoid just being clipped in the arrange-pass, if Im not mistaken. But I cant find any code for size-sharing at all with Reflector. Could someone explain how size sharing should be implemented roughly in a custom panel class with respect to measure and arrange?
Look at System.Windows.Controls.DefinitionBase
It's values (taken from sharedscope if used) are then used in grid.SetFinalSize

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

In Silverlight, I know RadTreeListView.VisibleElements gets me the currently loaded elements on the screen, but for example, if I have 20 elements but only 10 are loaded, I would like to retrieve 20 instead of 10.
The problem is that I do not know how to do this. I would appreciate any help.
Thanks in advance.
Ok. I have solved the problem and the solution has been as simple as binding the counter of the list which I am using to load the control.
The problem I am having now is that I have to retrieve the amount of filtered elements in the RadTreeListView. I am searching on the documentation and on the hierarchy's classes, but I do not find anything.
My goal is to have a diagram which look like this
Each arrow should be a one dimensional chart, where point are displayed (colors and point size depends on some values)
I'm building my own chart system because I spent a few hours looking for one which allow to custom markers (size and colors, and maybe even shape) but I couldn't find one.
Actually the only one I found is dynamic data display 2.0 which is only proposed in Silverlight.
My biggest problem is the two curving chart I have to do at the top of the diagram.
I tried to use PathListBox control, but because it's a listBox, I couldn't display items at fixed X position (like using a chart).
I'm not asking for a full perfect solution, but can someone give me advices, or clues ?
How would you manage to do something like that ?
It should only be a XAML work here, because all the data are already ready in a ListCollectionView (i'm using MVVM).
Thank you !
I've just created my first WPF application (3 calculators inside 3 different tabs).
The entire application has been built using widths/margins/paddings as static values, since I originally didn't know that dynamic values can be used by just putting an asterix after the value.
The client has come back to me though and has asked me to increase the size of the app, that includes form fields, tabs, font-sizes, grids etc...
What would be the easiest (and/or quickest) way to do this? I'd hate to go value by value resizing every single element since there are quite a few.
I can provide code but there is lots of it and I'm not sure of how much help it would be.
Appreciate your help,
Marko
Put it all in one ViewBox, play with viewbox size to change the app size
Write an XSLT transform to take your XAML as input and spit out appropriate modified XAML, which you put back in your app.
I have an app that creates a variable number of ScatterviewItems based on which tagged object is placed on the surface table.
The ScatterViewItems are added programatically to the ScatterView based on info looked up in a DB
The Scatterview does a good job of displaying this info
However, I would like them to be
evenly distributed across the table and
not have any items overlapping
Any ideas how to do that?
Sounds like you need collision detection.
There's two parts to this problem: detection and resolution. Detection is seeing if any item's bounding intersects with any other item's bounding. If the items are retangular or circular this is pretty straightforeward. It can get complex if you're dealing with other geometries.
Resoltion is what to do once you've detected a collision. Google will help you find the myriad algorithms for this. Here's a couple links to stackoverflow discussions: WPF: Collision Detection with Rotated Squares, Applying Coefficient of Restitution in a collision resolution method, Best way to detect collision between sprites?.
You can implement collision to work so that items bound off of each other as they scatter. Depending on the number of items, this might cause so much collision that the items don't scatter well. If this happens, just run the collision detection one items have stopped moving.
UniformGrid ?
You can also create your own panel by iheriting from Panel.
You will find some uber-valuable info in the Dr. WPF ItemsControl How-To series : http://drwpf.com/blog/itemscontrol-a-to-z/
That's a must-read, period.
ScatterViewItem has properties Center and Orientation which you can use to programmatically position items. If you know the size of each item you should be able to use these properties to position them in whichever way is ideal for your situation. By hooking into the Loaded event of each and checking ActualWidth/ActualHeight, you can get the dimensions. If you can use a fixed initial size for all of your SVIs, that's even easier.
You could lay them out by calculating a simple grid (plus some randomness to make it look more natural), or you may be looking for what's called a "force directed layout", which gives each object a repellent force relative to its size. After a while the elements will naturally be evenly spaced from one another, though they may still overlap if they run out of room. I haven't seen a WPF example of this, but see flare.prefused.org/demo (layout > force) for what I mean in Flash.
