Create click event from WPF MenuItem defined by a string

Question

I define parts of a menu with an array of string, and I want to automatically create click events for each of these. All of them are going to to the same thing, only a different parameter.

string[] goTos = new string[] { "First", "Second", "Third" };

When Initializing the window:

        foreach (string item in goTos)
        {
            System.Windows.Controls.MenuItem goTo = new System.Windows.Controls.MenuItem();
            goTo.Header = item;
            goTo.Name = "mnu" + item;
            mnuGoTo.Items.Add(goTo);
        }

How can I get click events for these?

Just add the event handler and within the event handler method determine which MenuItem called the handler by examining the sender parameter of your handler method. — Adwaenyth

The sender object passed to your handler method is the MenuItem object. So if you use (sender as MenuItem).Header you've got all you want. (You may need to add a check for null if the handler might get called from other controls too.) — Adwaenyth

if they are "going to to the same thing"

i suggest you use

<MenuItem Name="MenuItems" Header="Item1">
    <i:Interaction.Triggers>
           <i:EventTrigger EventName="Click">
               <ei:CallMethodAction TargetObject="{Binding}"MethodName="Event"/>
          </i:EventTrigger>
    </i:Interaction.Triggers>
</MenuItem>

on your View and add the event Method to your Viewmodel

if you do not use MVVM for your project, this is the perfect time to learn.

Make a method in your Viewmodel for the MethodName.

You Can try this

   string[] goTos = new string[] { "First", "Second", "Third" };
        foreach (string item in goTos)
        {
           System.Windows.Controls.MenuItem goTo = new   System.Windows.Controls.MenuItem();
            goTo.Header = item;
            goTo.Name = "mnu" + item;
            goTo.Click += new RoutedEventHandler(goTo_Click);
            mnuGoTo.Items.Add(goTo);
        }

    }

    void goTo_Click(object sender, RoutedEventArgs e)
    {
        throw new NotImplementedException();
    }
