I have define a style used in every instance of xamDataGrid in the application:
<Style x:Key="XamDataGridDefault" TargetType="igWpf:XamDataGrid"> <Setter Property="Theme" Value="Office2010Blue" /> </Style>
I have also added a reference to this theme in App.xaml like this:
<ResourceDictionary Source="/Themes/Office2010Blue/Office2010Blue.xamDataPresenter.xaml"/>
Problem is that on a standard computer the grid headings disappears after a while using this theme, and may appear again later. This never happen when I use the Aero theme. The application is installed on standard computers in our company using Click Once deployment.
I never see this on my development computer, may be because it has 8 kernals, Infragistics ultimate or a different graphics card/driver.
I suspect there might be an error in the Office2010Blue theme.
Hello,
Thank you for the additional information. To look into this, we do need to be able to reproduce the behavior. Have you been able to reproduce this in any smaller sample on the machines that do reproduce the issue or only in your application? For the machines that you have reproduced this on is there anything common to all environments such as the Windows OS version or video driver? I am asking because it seems that environment is a factor for the issue since you didn't reproduce this on your development machine.
Let me know if you have any questions.
Space remain reserved. Headings may disappear when we navigate to another ContentPane (XamDocManager) or another TabItem in a TabControl and return. Sometimes headings are still there when we return and sometimes they are not. Headings can appear again later when we switch back and forth several times.
I work in a very large company with thousands of PC's covering a broad range of models and configurations. One of the computers where I have observed this problem is a HP Compaq 8200 Elite with Intel i5-2400 CPU (4 kernels) with Windows 7 sp1.
We have observed the same issue on several PC's with different configurations. For this reason we wait for a solution before we migrate this theme into production version of the application.
When the headers disappear, does the space remain reserved for them and they just appear to no longer be drawn or do they collapse as if the Visibility is set to Collapsed? Do you have a screen shot?
What is a standard computer? Does the issue only happen on a single machine or many machines? If many machines, do they all have the same hardware, version of windows, and versions of the .NET framework?
Let me know if you have any questions with this matter.
No, I am using version 2013.2. I did the same test on the 2012.2 version. Experienced exactly the same problem in that version
HI,
Are you using an older version of our WPF Product? If you are, then try installing the latest service release for that version. If this does not resolve your issue. Then please let me know what version and build of the product you are using.
