It seems problem is not with the code you pasted here, it may be with client environment, connection, privileges etc. You must give more info about that 'it is not working in clients pc'. What systems they use, what is the error, have you tried debugging in client side?

*Edit:*then you have to find the problem tracing all the operation from the beginning. My advice is that make a dummy windows form application, just a standard form, a combobox and a button. ON the click event of button just do what you did. JUst bind the combo and send this temp app to the client. If it works then do step by step.Ex:

private void button1_Click(object sender, EventArgs e)
    {
        string conStr = "Data Source=PC-303\\SQLEXPRESS;Initial Catalog=sokaklar;User ID=sa;Password=*****";

        SqlDataAdapter adapter = new SqlDataAdapter("SELECT DISTINCT IL, IL_ID FROM sokaklar ORDER BY IL", new SqlConnection(conStr));
        DataTable dt = new System.Data.DataTable();
        adapter.Fill(dt);            

        comboBox1.DisplayMember = "IL";
        comboBox1.ValueMember = "IL_ID";
        comboBox1.DataSource = dt;            
    }

I created this app in one minute, and it is working for me.
