Hi,
I have a WPF control inside an ElementHost in an Outlook view region. Everything works great - I can resize the form using the splitter and the WPF control resizes smoothly as well. The problem is that when I resize the Outlook Window, the WPF control doesn't get redrawn / repainted and most parts are just white. When I minimize and restore the form region, everything looks good again.
Is there anything I can do to fix this behavior?
Thanks, Daniel |

Hello Daniel,
I'm sorry for the delayed response; I suppose I overlooked your post somehow. What are Outlook version, service pack and bitness? And in what layout do you show your region? What Add-in Express version do you use?

Hi Andrei,
Thank you for your answer!
I'm using Outlook 2013, 32Bit on 64Bit Windows 8 Professional machine. I'm using the very latest Add-in Express version. I have the same problem on 3 different machines (all with that configuration, one with Office365 Preview version of Outlook). I also have a virtual machine with Windows 7 Pro 64Bit and Outlook 2010, 32Bit. It looks a little bit different there, but basically it's the same issue.
If you want to, I can send you the source code as well (but would need your email-address then).
Thanks, Daniel |

Hi Daniel,
You can send the source code to the support email address; please find it in {Add-in Express}\readme.txt. Oh, please make sure that your email contains a link to this topic.

Hi Daniel,
I wasn't able to build your project but I was able to reproduce the issue with a simple add-in. The workaround is this:
private void ADXOlForm1_Resize(object sender, EventArgs e)
{
this.elementHost1.Child = null;
this.elementHost1.Child = this.userControl11;
}
Please note there are many issues when using WPF controls on a pane because the WPF core is partially incompatibile with Office GUI.

Hi Andrei,
Thanks! That works very nice in Outlook 2013. In Outlook 2010 it has become better, but there are still 2 issues:
- Redrawing now works when the resize changed the height of the Outlook window but it does not when we only change the width
- As soon as I hover the collapse button with my mouse (no clicking) the panel disappear and draws weird stuff
I will try to fix this on my own and update this thread here. Only if I can't get it running, I'll send you an email.
Many thanks,
Daniel |
