using DevExpress.XtraVerticalGrid.Rows;
//...

private void btnShowCustomizationForm_Click(object sender, EventArgs e) {
   // Show Customization Form.
    vGridControl1.RowsCustomization();
}

ContextMenu menu = null;
private void vGridControl1_ShowCustomizationForm(object sender, System.EventArgs e) {
   menu = new ContextMenu(new MenuItem[] {new MenuItem("Restore All")});
   menu.MenuItems[0].Click += new EventHandler(menuItem1_Click);
   vGridControl1.CustomizationForm.ContextMenu = menu;
}

private void vGridControl1_HideCustomizationForm(object sender, System.EventArgs e) {
   if (menu == null) return;
   menu.MenuItems[0].Click -= new EventHandler(menuItem1_Click);
   menu.Dispose();
   menu = null;
}

private void menuItem1_Click(object sender, System.EventArgs e) {
   RowOperationVisible RowOperatVisible = new RowOperationVisible();
   vGridControl1.RowsIterator.DoOperation(RowOperatVisible);
}


public class RowOperationVisible : RowOperation {
   public RowOperationVisible() {}
   public override void Execute(BaseRow row) {
      if (row.Visible == false && row.OptionsRow.AllowMoveToCustomizationForm) 
          row.Visible = true;
   }
}
