I am new in silverlight and i want to bind data from Entity Data source in combox like WindosForm for exmple

    private void Form1_Load(object sender, EventArgs e)
    {
        comboBox1.DisplayMember = "CategoryName";

Answer 1

Here you go

 comboBox1.ItemSource= NorthwindEntities.Categories; 

and you need to post XAML for more help.
