So im trying to load a different string when the user has selected a different item, my code:

void ModeSelectorSelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        var data1 = new string[]
                                        {
                                        "January 2012",
                                        "February 2012",
                                        "March 2012",
                                        "April 2012",
                                        };

        var data2 = new string[]
                                        {
                                        "Married",
                                        "Divorced",
                                        "Buy new house",
                                        "Get promotion",
                                        };
        if (_Menu2.SelectedIndex == 2) {

                _Menu3.ItemsSource = data1;

        }
        else if (_Menu2.SelectedIndex == 3)
            {

                _Menu3.ItemsSource = data2;
            }    

}

When I use just 1 string it works fine, but as soon as I try to load 2 different strings in the same drop down menu it shuts down, meaning that its not showing any string data at all. What am I doing wrong?

Check whether your control(of which the selected index has to be checked) causes a postback. If so, rebind the drop down menu. – Rohit Kiran 35 mins ago
@RohitKiran No clue how to do that. – Tarayaa 33 mins ago
Are you trying to load data from data1 and data2 into a single drop down. Please be specific. – Rohit Kiran 28 mins ago
Here u are taking _Menu3.ItemsSource. Is this datagrid or something else? – Anurag Jain 19 mins ago
@RohitKiran "I try to load 2 different strings in the same drop down", Yes I am. – Tarayaa 7 mins ago

For ASP.NET WebForms DropDownList follow this code snippet:

_Menu3.DataSource = someData;
_Menu3.DataBind();

Perhaps it would be better to move this logic on a client side and use javascript.
