Tab Control Breaking Causing Validation

   Hi,
This is related to the issue 

http://forum.codejock.com/forum_posts.asp?TID=19248&KW=&PID=66974&title=solved-groupbox-breaking-causesvalidation#66974

If i place a user control in a tab control when i click the tab headers the validation events do not fire correctly allowing me to change tab. This happens if i host a user control inside the tab page or inside a group box in the tab page. This doesn't happen if i place the user control inside a frame on the tab page. 

When a user control is inside a group box the event order is 

TestControlGroupTab:txtData_Validate
TestControlGroupTab:UserControl_ExitFocus
TestControlGroupTab:txtData_LostFocus

When the User Control is in a frame the event order is 

TestControlFrameTab:txtData_Validate

When the user control is not in a frame or group box the event order is. 

TestControlNoParentTab:txtData_LostFocus
TestControlNoParentTab:txtData_Validate
TestControlNoParentTab:UserControl_ExitFocus
TestControlNoParentTab:UserControl_ExitFocus

I have attached an example appliction of this behaviour in action. uploads/7709/ControlValidationIssue.zip
Note. Do not click between the user controls as this will get stuck in a validation loop.
Note. The user control and app must be compiled (and run using this) to correctly highlight the issue.
