Declaration

[Browsable(false)]

Public Overridable Property DockRow As Integer

Property Value

Type	Default	Description
Int32	-1

The bar row index when it is docked.

Remarks

If bar is docked to the right or left of a container’s border, the bar is rotated 90 degrees clockwise. Thus, columns and rows are also rotated. Keep than in mind when using this property. To apply changes made by the property, call the Bar.ApplyDockRowCol method. Otherwise changes do not affect current bar position.

Example

The following code shows how to create bars and bar items in code.

In the example two bars are created - a main menu (a bar that is stretched to match the form’s width), and a regular bar. The main menu will contain three sub-menus (File, Edit and View), each having its own bar items. The second bar will display the Output button, which is also available via the View submenu of the first bar:

Bars are added to the BarManager.Bars collection. Bar items are added to bars via the Bar.AddItem and Bar.AddItems methods.

To avoid flickering while adding and customizing bars and bar items, the code that performs the customization is enclosed with the BarManager.BeginUpdate and BarManager.EndUpdate method calls.

To respond to clicking bar items, the BarManager.ItemClick event is handled.

    barManager.BeginUpdate();
