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.
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.
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
Hello,
Development issue 160205 has been fixed and the fix was included in the service release that was released this week. You will be able to download this from the My Keys and Downloads page.
Let me know if you have any questions with this matter.
Hi, I've encountered a similar issue using the latest 13.2 service release. I've attached a sample application that replicates the problem.
Basically, you need to vertically resize the window so the XamDataGrid does not appear. Then resize the window horizontally one direction or the other. Finally, resize the window vertically again so that the XamDataGrid is visible. You should see that the headers are no longer visible. If you resize the window horizontally again, you should see the headers pop back in. In all cases, be sure NOT to use the corner/diagonal resize. Only use the vertical and horizontal resize.
We have a custom template for the grid, and I was unable to replicate the problem in the sample app until I added in this custom template. This is located at the top of MainWindow.xaml. So if you could point me to where the issue is in our template that could cause this, that would be great.
This got pushed off the first page so I wanted to make sure someone was looking into this?
Dierk,
The headers disappearing is happening only when VerticalAlignment is set to Top in the Border that contains the Grid with name "PART_ContentSiteGrid". If you remove this setting the headers will not disappear.
Fantastic, thanks.
