title: Only One Combobox Databinding Can Be Handled In The Form Load Event
body: <p>I have created a linq, and the result is to give me a list of itemtypes, and i tried to bind the list to the combobox, but it's very strange that after i set the DisplayMember and ValueMember for the first combobox, and then the load event seems to return, and never execute the rest of the codes</p>
  
  <pre><code>private void AddOpenOrderForm_Load(object sender, EventArgs e)
  {
      using (context = new MRP_DBEntities())
      {
  
           var query1 = (from i in context.LookUPs select i.itemType).Distinct();
           itemType1CB.DataSource = query1.ToList();
           itemType1CB.DisplayMember = "itemType";
           itemType1CB.ValueMember = "itemType";
  
           MessageBox.Show("The program will not reach the follow codes");
  
           itemType2CB.DataSource = query1.ToList();
           itemType2CB.DisplayMember = "itemType";
           itemType2CB.ValueMember = "itemType";
        }
  
  
  }
  </code></pre>
