There is an example of two-way binding to Center property from Micrsoft guys.
You can find it here.
Its sample works fine, but they disabled full animation. When I set AnimationLevel="Full" and use the Compass I get trembling picture.
I really like aminations effects and don't want to turn it off.
Are there any ways to get working Compass and keep full animation?
This is a known problem and as far as i know, it hasn't been fixed. I too would very much like it to be fixed.
When full animation is on and the map is moved, it will move the map in an arch (zooms out and then back in). However, small distance movements still use the arch and this creates the shaking.
I have searched extensively (4 months ago) for a good work around for this problem.
I didn't find anything other than turning off the full animation.

I want to render a virtualized list of images with variables heights, my current implementation is following the variable example on tanstack docs, but adding a random height src image and loading that instead of text as the content for the row item.
This is not working great and is a bit glitchy. Im using a best guess estimateSize but was hoping for a system that would fully calculate this for me.
The height is completely off until you scroll at least once, then the image heights seem to get calculated. Otherwise, once you start scrolling, the performance here is pretty good.
Any feedback on this implementation (no idea if this is how it's intended to be implemented), or indication on how I can fix the problem would be appreciated. Thanks!
My demo here:
https://codesandbox.io/s/boring-ishizaka-yiywvo?file=/src/main.jsx
p.s if you know how to achieve this with react-virtualized (with CellMeasurer) also keen to hear/see it. I've struggled with CellMeasurer and image onLoad to calc correctly.
Ok dug through some github issues, and mashed a few things together and this seems to be working well. https://codesandbox.io/s/usevirtualresizeobserver-04-11-2021-forked-yur6we?file=/src/App.tsx
It uses a custom wrapper that leverages ResizeObserver, shame this isn't something that's exported from the lib considering this would be a very common use case.
here is a much simpler solution with the new react-virtual version
the idea is to call measureElement on img onLoad
I'm a long-time user of SciChart, but it's an old version (3.1). I've just started using FastHeatMapRenderableSeries for the first time, and there is a requirement for a user to alter the chart's gradient stops. I've implemented a UI to do this (see image), which involves dragging markers that updates their respective gradient stop within the ColorMap's LinearGradientBrush. It's working in as much as gradient changes can be seen in the chart's HeatColorMap (not shown on this screenshot), and also in my "drag" control (a Rectangle whose Fill is bound to the ColorMap's brush).
The problem is that the colours within the chart itself don't change - perhaps I was being a little too hopeful that this would happen automatically! Is this possible, or will I have to recreate the series each time there has been a change to the gradient?
We actually have this working in a later version of SciChart. Im not sure which version exactly but it was introduced at some point. Have a look at this forum post which discusses a bug in the heatmap color map binding in v5.
In the v6 examples suite, you can drag the heat map legend and recolour the chart automatically, so we know in principle this works.
Very cool image by the way!
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

I'm currently using the Silverlight Map control for WP7, and am trying to visualize driving directions on the map. In order to highlight the route needed, I am using a MapLayer with a MapPolyline. The problem is that even with CacheMode set to BitmapCache, the MapPolyline area gets redrawn whenever the user pans or zooms the map. I've used other controls such as Ellipses or Pushpins, and with BitmapCache on, none of them redraw and give the same performance hit as MapPolyline.
Here's a quick example
<maps:Map ZoomLevel="3">
<maps:MapPolyline Name="line" Stroke="Red" StrokeThickness="9">
<maps:MapPolyline.CacheMode>
<BitmapCache/>
</maps:MapPolyline.CacheMode>
<maps:MapPolyline.Locations>
<maps:LocationCollection>
<geo:GeoCoordinate Latitude="33" Longitude="33"/>
<geo:GeoCoordinate Latitude="36" Longitude="33"/>
<geo:GeoCoordinate Latitude="33" Longitude="36"/>
</maps:LocationCollection>
</maps:MapPolyline.Locations>
</maps:MapPolyline>
</maps:Map>
If you set App.Current.Host.Settings.EnableRedrawRegions = true; you can see the redrawing that occurs. The performance is particularly bad when you have a larger polyline and zoom in closer.
Is there anything that can be done to help? The native Bing Maps has pretty smooth route drawing, so I would think that there should be a way to solve this?
Thanks!
Can you explain a bit more what the problem is?
I've got an app - RunSat - in which I draw polylines with several hundred points (e.g. I just looked at a 3 hour long bike ride) and this draws fine - including during zoom operations.
I don't understand the problem - even using the sample code above. To help - are you testing on a phone or on the emulator?
As for CacheMode and BitmapCache, I'm really not sure about using these settings for the map - I don't use them in RunSat if that helps - I just leave the phone alone to work out its own GPU drawing.
I would like to make a rotating form WPF effect like the one in the norton antivirus 2010.
The effect is a rotating form that changes the contents when the other side is shown. But the axis is not in the center of the form but moves from side to center and back. Like a three step effect.
The rotating form can be seen at 8' 07" in this video: http://www.youtube.com/watch?v=A3hHPdgi9Nk&feature=related (I'm sad but this was the only video I found on YouTube)
Thanks.
Have a look at the Thriple stuff on CodePlex: http://thriple.codeplex.com/
It's almost exactly what you're after.
Hope this helps.
I did not examine the details, but I know that Microsoft's patterns & practices team also uses a similar animation in their "StockTrader Reference Implementation" for the "Composite Application Guidance". They sub-classed the TabControl and added some animation to it. I think the relevant code parts can be found here:
AnimatedTabControl.Desktop.cs
Generic.xaml
just verify this link. It has code as well as the Sample.
From the Sample take the TransitionPresenter link from the left panel and choose the 3D Rotate item from the listbox. Then select the images from the top list. You can see the same effect in the video. I saw some initial sanp of the video and may be this link can help you.
