TabbedMdiContainer error during Coded UI Tests

Hi Sasha,

Container controls in the Docking/MDI product are created/destroyed as needed and each instance will have a unique GUID ID.  Thus the AutomationID will change as they are created.  That being said, I believe you can manually set the AutomationProperties.AutomationID for each container in your test.  That way you can give it a specific ID that won't change between run sessions.

I have such xaml code:

 When I run coded UI test and try to access checkBox, I get this error. But if I put this checkbox outside container and rebuild test, then it passes...  Any ideas why it is happening?

Thank you. 

Hi Sascha,

On a side note, you can't put controls like your Grid between the Workspace and the TabbedMdiHost.  That will cause problems in a production app since the Workspace expects MDI containers, if present, to be direct children.

Thank you for the test.  We've been working with it, but haven't been able to get the Coded UI to find the DocumentWindow within the TabbedMdiContainer as of yet.  I'm not sure why it's not finding it since when you look at the automation tree in UIVerify, it does show the DocumentWindow as a child of the TabbedMdiContainer.

Hi,

Thank you for pointing on my error.

About this issue with UI test - can you let us know, when you will fix this, because it is very important for our company.

Thank you for your help.

Hi Sasha,

We spent quite a while on this and ended up narrowing down the sample XAML you posted above.  It started working after I removed the nested ScrollViewer.  Basically it seemed like if there was a ScrollViewer in another ScrollViewer, it stopped finding controls.  Please try that out and see if it helps on your end.  If not, I'll send you the XAML we used to test.

Hi,

Yes, now it is working.

I just would like to know, if it is a bug, or we need to remove nested scrollViewer?

Thank you for your help.

It seems to be a bug in Coded UI so I would suggest coming up with a different usage scenario than nested ScrollViewers.
