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 !
In EXTJS PIE Chart i want to sort top 10 values and display in Descending order.
Currently it gets all records from store and displays. I need only top 10.
Can anyone guide me to solve this issue?
Thanks
I do not think it's' pie charts' job to show top 10 values. you should provide a process that will transofrm the original store in what you really need. A plugin that replaces the original store might be an ideea.
You can try sorting and filtering the store. I manipulated example code in ExtJS docs and figured, that data is displayed by given order. Maybe if you apply sorter to store you might get desired effect. As for filtering: find min value of top ten values and apply filter that leaves only values above it. Might work, but I haven't tried it.
I have an application written in Silverlight 5, which requires optimization.
Application contains a TreeView, each element of the tree contains about 25 editbox controls with background image. The tree has an average of about 50 elements, which makes ~ 1250 edit controls. The problem is that it scrolls the tree or select editboxs very very slowly, even if only 5-6 elements are visible.
I think virtualization in this case will not help because the problem is in the drawing of visible elements.
Does anyone have any idea how to optimize?
Can't post image becouse of my low score but one TreeView Item looks like:
Floor 4 (0xAA03) |EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB|EB (25)
where EB is EditBox in form of rectangle with image background and text for room number. Editboxs are created dynamic.
Thank you in advance.
Ok, it's difficult to give a qualified answer. But let's have a try. I think your statement virtualization won't help is not fully true, but it doesn't seem to be the main problem.
An educated guess is, that you're using DropShadows or OpacityMasks which are a real performance killer. If it's like that please remove them and tell me the result. Otherwise I'm running out of ideas, sorry.
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'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.
