My code is:
<igRibbon:XamRibbonWindow x:Class="Ribbon.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" xmlns:igRibbon="http://infragistics.com/Ribbon"> <igRibbon:RibbonWindowContentHost> <igRibbon:RibbonWindowContentHost.Ribbon> <igRibbon:XamRibbon Theme="Office2k7Silver"> <igRibbon:XamRibbon.QuickAccessToolbar> <igRibbon:QuickAccessToolbar> <igRibbon:QatPlaceholderTool /> <igRibbon:QatPlaceholderTool /> <igRibbon:QatPlaceholderTool /> </igRibbon:QuickAccessToolbar> </igRibbon:XamRibbon.QuickAccessToolbar> </igRibbon:XamRibbon> </igRibbon:RibbonWindowContentHost.Ribbon> </igRibbon:RibbonWindowContentHost></igRibbon:XamRibbonWindow>
The problem happens as soon as I put the Theme property in the Ribbon.
As soon as I remove it, the problem is gone.
I've removed the TargetID from the QuickAccessToolbar to reduce the code. This is just a demo project to show the problem.
It seems that the toolbar is throwing the exception at infragistics.Windows.Ribbon.QuickAccessToolbarPanel.RemoveVisualChildren()
I'm using Infragistics NetAdvantage 2010 Vol 1 with the SR or 02-April 2010
Thank you.
So based on the callstack can I assume that this is something you are seeing at design time in VS 2010? Are you using the RTM of VS? Is there any additional information that you can provide?
Hi!
I have the same problem. It is in the design view in VS 2010 (Version 10.0.30319.1 RTMRel). I'm also sure that the theme is the problem. Because any changes to the theme property removes the problem.
Sincerely,
voks
The code I gave should make your Visual Studio throw the designer exception,
I've only tested it with Visual Studio 2010. I don't know if it also happens with 2008.
I was able to reproduce the issue. It should be addressed in the next hotfix.
Thank you :-)
Hello,
This issue was fixed and the service release was just published. You should be able to download it.I hope this helps.
