Binding one listbox listboxitem from another listbox

Question

I am pretty new to C# WPF, so please bear with my question. I have two listboxes (listbox1 and listbox2) where the items in listbox1 will be added or removed during runtime through user input. I want the listbox2 to display its listboxitem accordingly through binding method.

For example, if listbox1 has 5 items initially, i want the listbox2 to display the same 5 items. If items in listbox1 being added or removed in runtime, I want the listbox2 to display the same data (items) as listbox1.

Can someone give me a tip? Thanks in advance.

You can bind both listbox with same data. Means use same DataSource for both listbox.

You are doing same operation on both listbox.

private static void btnAdd_Click(object sender,EventArgs e){
Listbox1.Items.Add("AAAA");
Listbox2.Items.Add("AAAA");
}

private static void btnRemove_Click(object sender,EventArgs e){
Listbox1.Items.SelectedItem[0].Remove();
Listbox2.Items.SelectedItem[0].Remove();
}

It's iether what jaideepsinh say and bind both of them to your original data. Or you bind listbox2 to listbox1 like so

XML

<ListBox Name="listbox1" ItemsSource="{Binding yourdatasource}">
 </ListBox>
 <ListBox ItemsSource="{Binding ElementName=listbox1, Path=ItemSource}">
 </ListBox>
