Hi Stefan,
1. Yes, it is possible to do multiple mainFrameBarManager.Items.AddRange
2. For this purpose, you should first get hold of the CommandBarExt object associated with each Bar and then set its DockState property to the appropriate values to create a desired ToolBars layout (refer code snippet below) :
CommandBarExt cmdbar1 = this.mainFrameBarManager1.GetBarControl(this.bar1) as CommandBarExt;
cmdbar1.DockState = CommandBarDockState.Top;
3. Yes, user customization works with multiple AddRange calls.
Please refer to the
sample application attached here, which illustrates all my responses above. We have worked a great deal on improving the performance of our Menus package, and several improvements have been incorporated in our latest release, v2.0.3.0. Please take a look at it and let me know if you have any suggestions. We appreciate your continued interest in Syncfusion products.
