Hello Kevin Duncan,

If you think of automatic binding to hierarchical data sources, currently RadMenu does not support this feature. This is on our list of new features, waiting for implementation.

There is still the possibility to create and initialize RadMenu dynamically at runtime with data produced from some database. Here is a sample how to create a RadMenu dynamically:

RadMenu menu = new RadMenu(); 

menu.BeginInit(); 

menu.Items.Add(new RadMenuItem("Item 1")); 

menu.Items.Add(new RadMenuItem("Item 2")); 

menu.Items.Add(new RadMenuItem("Item 3")); 

RadMenuItem item1 = (RadMenuItem)menu.Items[0]; 

item1.Items.Add(new RadMenuItem("Sub menu item 1")); 

item1.Items.Add(new RadMenuItem("Sub menu item 2")); 

((RadMenuItem)item1.Items[0]).Click += new EventHandler(item1_Click); 

menu.EndInit(); 

this.Controls.Add(menu);

We did a little research and didn't find other controls for WinForms that support data binding. Do you have experience with such a suite? We will be glad to review it if you can provide us with more information on your case.

Sincerely yours,

Jack,
How can I use a loop to populate my menu? I don't know how many items there are so I can't define the number of RadMenuItems.
How can I use a database to create a list that has years in it that when selected will open a side menu off of that year that will show some studies based on that year?

Menu
2009 > T09_1 > B1_1
                          B1_2
            T09_2 >
                          B2_1
            T09_3 >
                          B3_1
                          B3_2

2008 > T08_1 > B1_1
2007 > T07_1 > B1_1

I can create 1 query to bring back all this info then I need to find a way to add the menu item then the children menus.

Hi Jerry,

Once again you can find a sample on my weblog. I updated the little project. I added a radmenu that loads the things you said.
I hope that this will help you to a solution.

Gerbrand,
Man that was perfect.
I just ran into an issue after getting it working.
Is there a way to make an event for the article menu item? When the user clicks this I need to query the DB using all three menu options(Year, Study, Article).

You need to write a telerik book.

Thanks for the help again
Jerry

Yep you can add a event to the menu
See Jacks post:

((RadMenuItem)item1.Items[0]).Click += new EventHandler(item1_Click);

If I'm home I will add it to the little project.

Hi Jerry,

If you go to my weblog you can find an update of the little project. I added an eventhandler on the Article rad menu items. When clicked on one of those items a message box appear that says which item is clicked and what the parent items are. so I think you can use this.

Let me know if you have further questions.

Thank You again...

This should help move me in the correct direction...

Hi Manesh,

Thank you for writing.

The experienced behavior is the desired behavior. The mnemonics are activated only for open menus. Once you press Alt + V the menu for the Validation and Checks menu item is opened and the mnemonics will work only for its menu items, while you are trying to start a mnemonic of a main menu item. The behavior is the same with the standard menu and since we are trying to be consistent with the standard controls, it is the same in our suite.

As an alternative, I can suggest using RadShortcut for your scenario. Here is a small sample:

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

this.radMenuItem1.Shortcuts.Add(new RadShortcut(Keys.Control, Keys.D));

this.radMenuItem2.Shortcuts.Add(new RadShortcut(Keys.Control, Keys.R));

radMenuItem1.Click += new EventHandler(radMenuItem1_Click);

radMenuItem2.Click += new EventHandler(radMenuItem1_Click);

}

void radMenuItem1_Click(object sender, EventArgs e)

{

foreach (RadMenuItem item in radMenu1.Items)

{

item.HideChildItems();

}

(sender as RadMenuItem).ShowChildItems();

}

More information regarding RadShortcut can be found here: http://www.telerik.com/help/winforms/shortcuts-getting-started-(radmenuitems).html.

Off topic, this forum thread concerns a topic of different matter. Please avoid posting question in threads that are not related to it. If you cannot find the correct thread, you can always open a new one.
