Declaration
Property Value
Type | Description |
---|---|
NavBarGroup | A NavBarGroup object representing the group located under a test point. null (Nothing in Visual Basic) if the test point is not over a control group. |
Remarks
Use the NavBarControl.CalcHitInfo method to obtain information about a specified point’s location with respect to the control. If a specified point resides over the group (its caption or client area), the method assigns the NavBarGroup object representing this group to the Group property of the returned NavBarHitInfo object. If a specified point is not over the group, the Group property returns null (Nothing in Visual Basic).
You can determine whether the test point is over a group or group caption via the NavBarHitInfo.InGroup and NavBarHitInfo.InGroupCaption properties respectively.
Example
The following sample code represents a handler for the MouseMove event. It calculates hit information for the mouse pointer’s position via the NavBarControl.CalcHitInfo method. Then the group that is hovered over is accessed.
using DevExpress.XtraNavBar;
private void navBarControl1_MouseMove(object sender, MouseEventArgs e) {
NavBarHitInfo hitInfo = navBarControl1.CalcHitInfo(new Point(e.X, e.Y));
if (hitInfo.InGroup) {
NavBarGroup group = hitInfo.Group;
// perform operations on the group here
//...
}
}
