ClientTop

This property returns the top coordinate of the internal area, or display area, of the TabStrip control.

Syntax

object.ClientTop

Parameters

object

Object expression that evaluates to a TabStrip control.

Remarks

The ClientTop property is read-only at run time. It is unavailable at design time.

At run time, ClientTop automatically stores the top coordinate of the TabStrip control's internal area, which is shared by all Tab objects in the control. To ensure that the controls associated with a specific Tab appear when that Tab object is selected, place the Tab object's controls inside a container, create several Frame controls, move them over the tabstrip client area, and make them visible when the corresponding tab is selected.

All client-coordinate properties use the scale mode of the parent form. The following code example shows how to place a Frame control so that it fits perfectly in the internal area.

Frame1.Left = TabStrip1.ClientLeft
Frame1.Top = TabStrip1.ClientTop
Frame1.Width = TabStrip1.ClientWidth
Frame1.Height = TabStrip1.ClientHeight

To create the effect of placing a new tab and its associated container on top when the tab is selected, complete the following tasks:

• Set the size and location of the container in the TabStrip control's internal area to the client-coordinate properties.
• Use the ZOrder method to place the selected tab's container control at the front or back of the z-order.
