Control.SelectNextControl Method

Updated: September 2010

Activates the next control.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public bool SelectNextControl(
	Control ctl,
	bool forward,
	bool tabStopOnly,
	bool nested,
	bool wrap
)

Parameters

ctl
Type: System.Windows.Forms.Control

The Control at which to start the search.

forward
Type: System.Boolean

true to move forward in the tab order; false to move backward in the tab order.

tabStopOnly
Type: System.Boolean

true to ignore the controls with the TabStop property set to false; otherwise, false.

nested
Type: System.Boolean

true to include nested (children of child controls) child controls; otherwise, false.

wrap
Type: System.Boolean

true to continue searching from the first control in the tab order after the last control has been reached; otherwise, false.

Return Value

Type: System.Boolean
true if a control was activated; otherwise, false.

The SelectNextControl method activates the next control in the tab order if the control's Selectable style bit is set to true in ControlStyles, it is contained in another control, and all its parent controls are both visible and enabled.

The Windows Forms controls in the following list are not selectable. Controls derived from controls in the list will also not be selectable.

When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus events occur in the following order:

  1. Enter

  2. GotFocus

  3. Leave

  4. Validating

  5. Validated

  6. LostFocus

If the CausesValidation property is set to false, the Validating and Validated events are suppressed.

The following code example shows the SelectNextControl method being used in a form that has some controls. Each time that you click the form, the next control is activated. The ActiveControl property gets the currently active control in the container control.

private void Form1_Click(object sender, EventArgs e)
{
    Control ctl;
    ctl = (Control)sender;
    ctl.SelectNextControl(ActiveControl, true, true, true, true);
}

The following code example shows the SelectNextControl method being used in a form that has a Button and some other controls. When you click the Button, the next control after the Button is activated. Notice that you have to get the parent of the Button control. Since Button is not a container, calling SelectNextControl directly on the Button would not change the activation.

private void button1_Click(object sender, EventArgs e)
{
    Control p;
    p = ((Button) sender).Parent;
    p.SelectNextControl(ActiveControl, true, true, true, true);
}
