Rows White-out in Windows 8.1 - IE 11

[Nathan]

We upgraded some machines to Windows 8.1, and as a result got IE11.  When using the RadGridView, if you mouse over the rows they turn white

Before:





After Dragging the mouse around the grid (no click, just mouse-over):





If you click on a cell, the white-out goes away, but it is pretty bad for usability.  This gridview is using themes, not sure if that is the cause.  Works well in Chrome and earlier versions of IE.  Any ideas?



Thanks

[Kris]

I have the same problem and hope there will be a workarround.

Otherwise i will have to drop all Telerik RadGridViews and replace them with the standard lists.

Hello,

Unfortunately, we were not able to reproduce the problem on our side. May I ask you to share some more details? Could you specify the version of RadControls for Silverlight you are currently using? Are you using Implicit styles? Have you made any customizations to GridViewRow style?
It will be of great help if you send a simple runnable project which we can debug on our side.

Hello,

I have something that looks like this problem, since I am using Windows 8.1 in combination with VS2013 some styles on my radgrid are not applied.

It looks like the picture added to this post. Am I the only one with this problem?

Sander

[Kris]

Ok, i will try to make an example.

I'm using version  2013.1.220.1050 so i will first try to upgrade to the latest version and see if my problem is gone.



Telerik online demo's work fine here on Win8.1+IE11.

One more thing :

The blank lines appear only when hovering over the gridview when IE is maximized !

Otherwise (not maximized) all runs fine.



Grtz,

Kris

[Nathan]

Just want to confirm what Kris said (good catch!).  Just tested ours with IE not in full screen, and the issue with the lines whiting out goes away.  Once you maximize the window, it comes back.

[Kris]

Upgrade to   2013.3.1016.1050   did not help.

Reproducing the sample didn't work out : can't get it to do the wrong things.

Stripping code and UI from my existing program never solved the problem.



I'll give it some thougth now.



Grtz,

Kris

[Nathan]

Messed with it again, looks like it doesn't start happening when it's maximized, just large.  When I resize the window to close to the size of the whole screen (about 95-98%), I start getting the whiteout.  Once it's smaller than that, the whiteout doesn't show.  The grid does reside in a viewbox in my project among other things, so any one could be causing the bug.  Tried to make a sample project but still can't recreate it.  I'll keep messing with it later on.

[Kris]

About the same story here,

only it keep's getting wrong until i make it about 2/3th of the screen.



Anything less is ok.



Grtz,

Hello,

Thank you for the additional details.
Unfortunately, I am still not able to reproduce the wrong behavior. Please take a look at this video and let me know if I am missing something.

I saw this type of distortion with the new IE 11 browser.  I thought it was a control problem but I had to update my video driver to work with 8.1.  
I still have issues with some of the Telerik controls (Calendar, etc) but the distortion was fixed with the driver update.

Also, I had to check Use software rendering instead of GPU rendering under Internet Option/Advanced tab.

Thanks,
Tim

[Kris]

I don't think this is a driver problem, because in Firefox, with the same driver everything was fine.



Also found out that even with a maximized window, when i make the left panel big enough (and the grid gets smaller), the problem is gone too.

Hello,

Kris has noted that our online demos work fine. Have you tried GridView theming demo? Could you please test it with each theme and let me know whether you are getting the same incorrect behavior? You can also try to set a different theme in your own application.

Regards,
Vera
Telerik

[Nathan]

I tested the demos, and the issue did not manifest.  I have even copied the grid and most of the code into a test project and I cannot get it to reproduce... this is a tricky one for sure.  The project I am copying from is a fairly large project, so maybe it has something to do with the amount of grids, etc. on screen at once?

[Vera]

Hi Nathan,

We are still trying to identify the problem. What I can suggest you is to set a different theme in your project and test if the incorrect behavior occurs. Do you all use Expression_Dark theme?
Also, what is the panel hierarchy you have placed RadGridView in?

Hi,



Monday i spent a lot of time stripping down our full app  to a sample package.

In the last half our, fixing the errors, the problem disappeared again :-(.





We use the OfficeBlue theme, but striping every theme resource and code didn't help me.





Mainpage :





Dynamicaly loaded user control in ContentControl "MainPage" (i know, bad naming) :

Can confirm the same is happening on Windows 8.1 clients for Silverlight applications that we are running:

I can't currently find steps to reproduce, will update if I find any pattern

Thanks,

Hello,

Could you try setting RadGridView.GroupRenderMode="Flat" and check whether the problem will appear?

[Kris]

Problem remains with GroupRenderMode Nested or Flat

Hello Kris,

Unfortunately, we are still not able to reproduce the problem locally. It will be of great help if you try isolating the problem in a sample project and send it to us. Once we reproduce the problem we will debug it immediately in order to provide a solution.

For what it's worth, I'm having the same problem.  See screen shot below.  I too am using Windows 8.1 with IE 11.  I'm using the Windows 7 theme

[Kris]

Again tried to make a sample project.

With just the main window and the problem window left, i nearly  succeeded.

Took a copy to another location, got an error : could not load the silverlight debugger and the problem was gone.



Just tested a company website with the problem from my development machine : white-out's

Tested the same website from my home pc (which also has Windows 8.1 and IE 11) : no problem !!



I don't realy know what to think about all this, but it might be something with the SilverlightDebugger that if installed and loaded gives a problem.



Grtz,

Kris

[Kris]

One more strange thing i discoverd :

- Set Silverlight project as startup-project and F5 : error :





- Same but CTRL-F5 (start without debugging) : problem is gone



-Set Web project hosting the silverlight project as startup : F5 or CTRL-F5 : white-out..



(If i succeed in zipping and moving the solution it would still be much bigger then 2Mb more like 60 i guess)

Hi,

Finaly made a sample : http://www.gosoft.be/RIP-GebruikersBeheerKopie.zip

Hello Kris,

Thank you for the project.

We were able to reproduce the problem and will start investigating it. We will contact you once we have more information.

Hello,

Thank you for the attached project. We have managed to reproduce the issue on Microsoft Surface Pro. It seems that Silverlight's VisualStateManager fails to render the MouseOver animation properly. Can you please confirm whether you have managed to reproduce the issue on a non-touch device?

Ivan Ivanov

[Kris]

Hi,

Yes, my developer laptop, on which i have the issue is a Fujitsu Lifebook without touch.



Grtz,

I am able to see this problem on other sites that don't use Telerik controls.  On Skype forum http://community.skype.com/t5/Windows-desktop-client/bd-p/Windows I can see the problem when the mouse hovers over the rows.

If I enable Use software rendering instead of GPU rendering under Internet Option/Advanced tab, the problem is gone.   

Also, I upgrade to 8.1 from 8.  I don't know if your testing environment started from a clean 8.1 install but that may make a difference. 

See video. http://kingdomware3.brinkster.net/sample.mp4

Tim

[Kris]

Hi,

On Skype forum i can't see anything wrong here.



But...If i enable Use software rendering the problem is indeed gone !

I did upgrade from 8 to 8.1 on both machines (and my home computer did not have this problem when surfing to the same site)..



So, this is probably a bug in IE ?



This is good enough for me

Thank you

Kris

[Yordanka]

Hi,

We've investigated the problem and it seems to be related to VisualStateManager, the Mouse Over VisualState and InternetExplorer 11. I was also able to reproduce it with the Microsoft DataGrid.
What we can suggest as a workaround for RadGridView is to edit the GridViewRow's template and remove the part for MouseOver state. The cons of this solution would be that the GridView will not have any style applied on mouse over.

Hello,

we also experience this problem on a Windows 8.1 machine with SL 5.1.20913.0 installed, with browsers IE11 and FireFox 25.0.1 (and maybe some others, not tested yet). The problem starts occuring when the grid's display area becomes 'sufficiently large'.
Is there any follow up on this issue (have you reported this problem on microsoft connect?)
 
With kind regards,

Paul D'hertoghe

[Yordanka]

Hello Paul,

Thank you for the feedback.

Unfortunately, we don't have any new information for that problem. We will report it to Microsoft as well.

Hi, Any news on this topic ? This is quite a major issue...

[Dimitrina]

Hi,

We have reported the issue to Microsoft. I am afraid there is still not an update though.

We had the same issue but not just in the RadGridView/DataGrid but also in the ListBox control too.  Setting <param name="enableGPUAcceleration" value="true" /> in the Default.aspx page fixed the problem accross the application for us.

Might be worth a try.

[Jean Ressouche]

Phillip you changed this normal day in a better day !

Working for me too (GridView & Scheduler), not glitches anymore :-)
