BUG: TabStrip Control's TabStyle Has No Effect at Run-Time

MORE INFORMATION

If you have more then one row of tabs, the TabStyle property determines how remaining rows of tabs in front of a selected tab are repositioned. If you set the TabStyle to tabTabStandard, the remaining tabs remain on the same side of the control. If the TabStyle is set to tabTabOpposite, the row(s) of tabs in front of the selected tab are repositioned at the opposite side of the control. For the default value of the placement property, this would be top and bottom, respectively. However, changing the TabStyle property at run-time has no effect on how the tabs are displayed.

Steps to Reproduce Behavior

1. Create a new Standard EXE project. Form1 is created by default.
2. Using the Projects menu, select Components to bring up the Components dialog box. On the Controls Tab, select "Microsoft Windows Common Controls 6.0," and then click OK.
3. Place a TabStrip and two CommandButtons on Form1.
4. In the Property Page for the TabStrip, set the MultiRow property to True. Then add enough Tabs so you have more than one row of tabs.
5. Add the following Code to Form1:

         Private Sub Command1_Click()
           TabStrip1.TabStyle = tabTabOpposite
           Debug.Print TabStrip1.TabStyle
         End Sub
   
         Private Sub Command2_Click()
           TabStrip1.TabStyle = tabTabStandard
           Debug.Print TabStrip1.TabStyle
         End Sub
   
         Private Sub Form_Load()
           Command1.Caption = "Tab Opposite"
           Command2.Caption = "Tab Standard"
         End Sub
   						

6. Save and run the project. Click on the Tab Opposite button, then try selecting tabs from different rows. Click on the Tab Standard button, and then try selecting tabs from different rows. You will not see any change.
7. Return to design mode and set the TabStyle to 1-tabTabOpposite in the Property Page for the TabStrip. Then run the project and try selecting tabs from different rows. You will see the correct behavior.
