I am trying to use the MainMenu control dynamically from a database and therefore trying to generate the entire menu from c# code.  I am trying to get the "sub" (second level) menu items to append to the MainMenuItem but I'm missing something.

Here is what I have so far and FYI the Main Menu Items do appear correctly.

        private void ws_GetMainMenuCompleted(object sender, GetMainMenuCompletedEventArgs e)

        {

            if (e.Result != null)

            {

                int i = 0;

                while (i <= e.Result.Count - 1)

                {

                    MainMenuItem mainMenuItem = new MainMenuItem();

                    mainMenuItem.VerticalAlignment = VerticalAlignment.Center;

                    mainMenuItem.HorizontalAlignment = HorizontalAlignment.Center;

                    mainMenuItem.IconColumnWidth = 0;

                    mainMenuItem.ID = e.Result[i].MenuID.ToString();

                    mainMenuItem.Text = e.Result[i].MenuName;

                    mainMenuItem.Tag = e.Result[i].UserControl;

                    mainMenuItem.Background = new SolidColorBrush(Colors.Transparent);

                    mainMenuItem.Foreground = new SolidColorBrush(Colors.White);

                    int x = 0;

                    if (e.Result[i].childItems != null)

                    {

                        if (e.Result[i].childItems.Count > 0)

                        {

                            while (x <= e.Result[i].childItems.Count - 1)

                            {

                                MenuItem subMenuItem = new MenuItem();

                                ItemsControl thisParent = ItemsControl.ItemsControlFromItemContainer(mainMenu);

                                subMenuItem.VerticalAlignment = VerticalAlignment.Top;

                                subMenuItem.HorizontalAlignment = HorizontalAlignment.Center;

                                subMenuItem.IconColumnWidth = 0;

                                subMenuItem.ID = e.Result[i].childItems[x].MenuID.ToString();

                                subMenuItem.Text = e.Result[i].childItems[x].MenuName.ToString();

                                subMenuItem.Tag = e.Result[i].childItems[x].UserControl.ToString();

                                //Need to add subMenuItem to mainMenuItem here

                                x++;

                            }

                        }

                    }

                    mainMenu.Items.Add(mainMenuItem);

                    i++;

                }  

            }

        }

Any help is appreciated.

Thanks

Hi,

Yes, when you have created the sub menu you need to assign this to the Content property of the MainMenuItem like this:

mainMenuItem.Content = subMenuItem;

I would place this where you currently have your comment:

//Need to add subMenuItem to mainMenuItem here

Thanks!

Thank you for the quick reply it got me going down the right path.  One interesting thing that I found is my subMenuItem had to be casted as a MenuItem in order to be added as Content to my mainMenuItem otherwise I was getting an exception error, but with that changed it works great.

Here's its' current state.

private void ws_GetMainMenuCompleted(object sender, GetMainMenuCompletedEventArgs e)

        {

            if (e.Result == null)

            {

                Common.PopupMessage("Not Authenticated. Please close and reopen your browser.");

            }

            else

            {

                mainMenu.Width = ContentGrid.ActualWidth;

                mainMenu.HorizontalAlignment = HorizontalAlignment.Center;

                mainMenu.VerticalAlignment = VerticalAlignment.Center;

                mainMenu.HorizontalContentAlignment = HorizontalAlignment.Center;

                mainMenu.VerticalContentAlignment = VerticalAlignment.Center;

                int i = 0;

                while (i <= e.Result.Count - 1)

                {

                    MainMenuItem mainMenuItem = new MainMenuItem();

                    mainMenuItem.ID = e.Result[i].MenuID.ToString();

                    mainMenuItem.Text = e.Result[i].MenuName;

                    mainMenuItem.Tag = e.Result[i].UserControl;

                    mainMenuItem.Background = new SolidColorBrush(Colors.Transparent);

                    mainMenuItem.Foreground = new SolidColorBrush(Colors.White);

                    if (e.Result[i].childItems.Count > 0)

                    {

                        Menu subMenu = new Menu();

                        int x = 0;

                        while (x <= e.Result[i].childItems.Count - 1)

                        {

                            MenuItem subMenuItem = new MenuItem();

                            subMenuItem.ID = e.Result[i].childItems[x].MenuID.ToString();

                            subMenuItem.Text = e.Result[i].childItems[x].MenuName.ToString();

                            subMenuItem.Tag = e.Result[i].childItems[x].UserControl.ToString();

                            subMenu.Items.Add(subMenuItem);

                            x++;

                        }

                        mainMenuItem.Content = subMenu;

                    }

                    else

                        mainMenuItem.MouseLeftButtonDown += new MouseButtonEventHandler(mainMenuItem_MouseLeftButtonDown);

                    mainMenu.Items.Add(mainMenuItem);

                    i++;

                }

            }

        }

I meant to say is my subMenuItem had to be added to a new instance of a Menu in order to be added as Content to my mainMenuItem.

instead of

"One interesting thing that I found is my subMenuItem had to be casted as a MenuItem in order to be added as Content to my mainMenuItem"

Hi, Dan: I have this subMenu working greate. Thanks! But I am having problem to see all items in submenu, since the submenu is close to the bottom of the screen. Is there any way to reposition the submenu or scroll down the submenu items?

Thanks!

Hi Jin,

Sorry, this is not possible at this time.  It is something we will look into to see how to implement this functionaily in a future version.

Thanks!
