  ComboBox driving me crazy

  Feb 15, 2012 09:27 AM|LINK

  Hi,

  Can anyone please give me a sample of how to use the control toolkit combobox, to display a list of OU's from active directory. which can then be selected to use in object creation.

  I've been trying for hours, and i have managed to get the combobox to display all the current ou's. but selecting any of them and then doing a postback, returns no item selected.

  Below is the bit of code i had been using for generating the ou list, can you tell me how to properly pass this list to a combobox.

  public static List<DirectoryEntry> Clients()
          {
              List<DirectoryEntry> clients = new List<DirectoryEntry>();
              try
              {
  
  
                  foreach (DirectoryEntry child in domain.Children)
                  {
                      clients.Add(child);
                  }
              }
              catch (System.Exception ex)
              {
                  
                  throw ex;
              }
  
  
              return clients;
          }

  Cheers

  Are you only populating the ListBox if !IsPostBack (If Not IsPostback in VB)?  If you bind the ListBox again in Page_Load after a postback (which is what it sounds like you are doing), it will overwrite the selection before calling your ListBox_Selected event.

  Hi,

  here is the method i am using for populating the list in page_load

  if (!IsPostBack)
              {
                  combClients.DataSource = ADLink.Clients();
                  combClients.DataBind();
                  
  
              }

  I dont have a selected event, could that be the problem?

  Sorted it, was being a muppet, had a clear.items method being called on the combobox on page load :(
