We are using Infralution 4.1.1 & Visual Studio 2010, recently we noticed Infralution Virtual Tree Editor - Auto Generate not showing available objects.

It was working fine previously on all developer machines, now it not working to any developer machines. We used auto generate previously to setup binding, now when we drop down the list it shows processing but no list displayed and we have to press Cancel at the end. In some developer, pressing Auto generate binding - drop down list disappear the dialog.

Please see a short video of the issue: http://screencast.com/t/W4IB4a2z9mO

I was managed to get the auto generate working once today by:

- Closing Visual Studio
- Uninstall Infralution
- Restart machine
- Install Infralution 4.1.1

However, as soon as we exit VS 2010, then reload the project, the issue reappeared.

Visual Studio Information...

Microsoft Visual Studio 2010
Version 10.0.40219.1 SP1Rel
Microsoft .NET Framework
Version 4.0.30319 SP1Rel
OS: Windows 7

We also tried 4.1.2 which showing different issue, no little arrow to enable you to edit the Virtual Tree View properties and you cannot select the tree view control in the forms designer, only from the controls dropdown list.

Do you have any suggestions to fix this issue?

Thanks in advance.

We will take a look at the issue - it may be related in someway to the types actually included in your project. As a workaround instead of using the dropdown arrow to browse types you could instead just enter the type name directly. You should enter the assembly qualified typename eg

MyNamespace.MyClass, MyAssemblyName

Thanks for your response.

Your workaround approach seems to work for some types but not others for which we need object binding.

Some background, we have a class hierarchy as shown below:

ItemHelper
- CallHelper (descendant class)
- UserHelper (descendant class)
...

We have tried the fully qualified name, see results below:

- MyNamespace.ItemHelper (works)
- MyNamespace.ItemHelper, MyAssemblyName (works)
- MyNamespace.CallHelper, MyAssemblyName (does not work)
- MyNamespace.UserHelper, MyAssemblyName (does not work)

The error message we get is "Entered type could not be found...": http://screencast.com/t/jAyOJVKO

On a separate note, in the Infralution Virtual Tree editor - Data Binding tab, we deleted all bindings (just to test). Now the dropdown works and also, we can enter the fully qualified type name; neither was working before.

However, if we save the project and restart Visual Studio, auto generate and the work-around of entering the fully qualified name no longer works.

We have tested this on multiple machines (Windows 7, XP) with the same results.

Any suggestions?

What language are you using (VB.NET or C#)?

Is there anything different about the classes that you having trouble with the auto generate bindings? Are they generics for example?

I've tried to replicate your issue with the Virtual Tree sample VS2010 projects using the same configuration as you - but have been unable to. Do you get the same issue with any of the sample projects?

Are the classes you want to bind to defined in the same project as your Virtual Tree instance? Have you rebuilt the solution to ensure the assemblies are built?

You should still be able to create bindings and columns for your classes manually. The Auto Generate function just provides a quick way of doing this by automatically creating columns and bindings for each public property of the class. You can manually add columns and then add an Object Binding for your class and create CellBindings for each of the fields. The help has some guidance on this.

If you can replicate the problem in a small project that you can email to support@infralution.com that would help a lot in trying to track down the source of the problem.
