c# Listbox and Tabpage

I have 2 Listbox on different tabpages that uses the same datasource

Basically its tabpage1 + listbox1 and tabpage2 + listbox2

I'm trying to do the following :

When I select Item from listbox1 on tabpage1 , I want the same item selected to listbox2 on tabpage2

I tried this:

listbox1.SelectedItem = listBox2.SelectedItem;

also this :

string sitem = "";
sitem = listbox1.SelectedItem.ToString();
listbox2.SelectedItem = sitem

nothing works as expected, I'm wondering if its possible ?

Set SelectedIndex property of listbox2:

listbox1.SelectedIndexChanged += delegate(object sndr, EventArgs args)
{
    var lst = (ListBox) sndr;
    listbox2.SelectedIndex = listbox2.Items.IndexOf(lst.SelectedItem);
};

Finally I made it with the example of PaulF

here is my working code :

 private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        string sitem = listBox1.SelectedItem.ToString();
        int index = listBox2.FindString(sitem);
        listBox2.SetSelected(index, true);
    }

so when I select item in listbox1, it also select it in listbox2

Make sure the tabControl is declared as public or internal. if not then change the tabControl from private to public in the designer.cs file

private System.Windows.Forms.TabControl tabControl1;

public System.Windows.Forms.TabControl tabControl1;

and then

using (Form form = new Form())
{         
     form.listbox1.SelectedItem = form.listBox2.SelectedItem;
}
