Hi Telerik
I have a hierarchical menu like:
Menu: A
Submenus: A.1, A.2
Sub-submenus: A.1.1, A.1.2
Is it possible to get a click-event when clicking on A or A.1? Normally it only comes when clicking on A.2, A.1.1 or A.1.2.

It’s really important for one of my controls to have this function so I know at witch level in the hierarchy, that the user makes a choice that releases a click-event and leaves the menu.

Thanks from Kenneth

Hi Kenneth,

There is an easy way to achieve this. Just set NotifyOnHeaderClick="True"  and the ItemClick event will be fired even if you click on parent items.

Hope this helps. Don't hesitate to contact us if you have other questions.

Kind regards,

Hi again
I have this menu with:
Items,
Sub-items,
Sub-sub-items,
Sub-sub-sub-items.

 

When a user clicks on one of the items, I simply needs to get the Headers content but I can't figure out how to read it.

I have built an event as follows:

private void RadMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
       {
           RadMenuItem item = e.Source as RadMenuItem;
           object Header = item.Header;
           //I would like to be able to read the content of the header someway like although this doesn't work:
           string Navn = Header.Where(n => n.Navn).ToString();
       }

But I don’t know how I can read the content of Header.

I have attached an image that shows, that I want to be able to read the variable called Navn.

 

I hope you can help me once again :-)

With kind regards from Kenneth

I know this for sure isn't pretty but it works.
Perhaps someone can suggest an easyer way of doing it?
private void RadMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
       {
           RadMenuItem item = e.Source as RadMenuItem;
           object Header = item.Header;
           string Navn = "";
           if (item.Items.Count > 0)
           {
               switch (item.Items[1].ToString())
               {
                   case "bygdrift2.Web.Services.BygdriftServiceClasses.rumNrList_Ejendom":
                       Navn = ((bygdrift2.Web.Services.BygdriftServiceClasses.RumNrList)(Header)).Navn;
                       break;
                   case "bygdrift2.Web.Services.BygdriftServiceClasses.rumNrList_Sal":
                       Navn = ((bygdrift2.Web.Services.BygdriftServiceClasses.rumNrList_Ejendom)(Header)).Navn;
                       break;
                   case "bygdrift2.Web.Services.BygdriftServiceClasses.rumNrList_Lokale":
                        Navn = ((bygdrift2.Web.Services.BygdriftServiceClasses.rumNrList_Sal)(Header)).Navn;
                       break;
               }
           }
           else
           {
               Navn = ((bygdrift2.Web.Services.BygdriftServiceClasses.rumNrList_Lokale)(Header)).Navn;
           }
           RadWindow.Alert("Navn is: " + Navn );
       }

Thanks from Kenneth

My menu item stays open even after being clicked
I'd rather not have to do any form of "is open" binding.

Hello Yen-Sheng,

May we receive more information on your case - which version of RadControls are you using, what exactly do you want to happen and the way you are using RadMenu? If you put all this stuff in a sample project it will be a great help for us.

Looking forward to hearing from you!

Kind regards,

Telerik version 2012.2.730.1040
<Grid x:Name="grid">
    <telerik:RadButton>
        <telerik:RadContextMenu.ContextMenu>
            <telerik:RadContextMenu
                NotifyOnHeaderClick="True">
                <telerik:RadMenuItem Click="RadMenuItem_Click">
                    <telerik:RadMenuItem.Header>
                        <TextBlock Text="Parent Component"/>
                    </telerik:RadMenuItem.Header>
                    <telerik:RadMenuItem Click="RadMenuItem_Click_1">
                        <telerik:RadMenuItem.Header>
                            <TextBlock Text="Child Component"/>
                        </telerik:RadMenuItem.Header>
                    </telerik:RadMenuItem>
                </telerik:RadMenuItem>
            </telerik:RadContextMenu>
        </telerik:RadContextMenu.ContextMenu>
        <TextBlock Text="Button"/>
    </telerik:RadButton>
Click events can have whatever you want in them.

Also, are child components suppose to notify the header when clicked?

Hello,

Please add name to your contextMenu and in the parent Item click event set IsOpen property to false:
...
 <telerik:RadContextMenu x:Name="radContextMenu" NotifyOnHeaderClick="True">
...

private void RadMenuItem_Click(object sender, Telerik.Windows.RadRoutedEventArgs e)
{
    radContextMenu.IsOpen = false;
}

It is expected for the children to notify their parents when they are clicked and then both click events (on the child and on the parent) are raised.

Hopefully this helps.

Somewhat.
I do realise that being able to click on a parent Item is highly unorthodox.
