After I used Visual Studio 2008 for Dynamics AX 2009 enterprise portal development for a couple of weeks, I found the Dynamics AX tool box items were not showing properly. Only AxLookup and AxGridView control were listed on the tool box.
I tried the following steps to resolve the issue:
1. Navigate to C:Users<username>AppDataLocalMicrosoftVisualStudio9.0 (on Vista or Longhorn) or “C:Documents and Settings<username>Local SettingsApplication DataMicrosoftVisualStudio9.0” (older Windows versions). You would need to delete these files:
2. Restart the Visual Studio 2008
Right click on the tool box and select ‘Choose items’.
In the ‘Choose Toolbox Items’ dialog, make sure all the Ax* controls are selected, and click "OK’ to close the dialog.
Right click on the tool box again and select ‘Show all’.
Now you can have all the Ax controls back on the tool box.
