Hello,

I was not able to see the first item selected using NetAdvantage version 12.1.20121.2072 and IE 9. I used below HTML mark up and code to test this:

HTML MarkUp:

<ig:WebDropDown ID="WebDropDown1" runat="server" Width="200px" EnableMultipleSelection="True"> </ig:WebDropDown>

Code:

DropDownItem wd = new DropDownItem(); wd.Text = "First"; wd.Value = "1"; this.WebDropDown1.Items.Add(wd);

DropDownItem wd1 = new DropDownItem(); wd1.Text = "Second"; wd1.Value = "2"; this.WebDropDown1.Items.Add(wd1);

If you want to clear selected items explicitly on page load, I would suggest you to use SelectedItems.Clear(); method as shown below:

 if (!IsPostBack)

this.WebDropDown1.SelectedItems.Clear();

I hope this helps.

You can take below approaches to implement the behavior you described:

1) Set DisplayMode = DropDown, and cancel the ValueChanging client-side event, in case the entry doesn't match an item as shown on the above forum thread.

2) You can add first item and hide it as shown below:

Me.WebDropDown1.Items.Insert(0, New DropDownItem(" ", " ", "", "")) Me.WebDropDown1.Items(0).Visible = False

3) You can handle client side Initialize event of WebDropDown and unselect item and checkbox as shown below:

function WebDropDown1_Initialize(sender, eventArgs) {  ///<summary>  ///  ///</summary>  ///<param name="sender" type="Infragistics.Web.UI.ControlMain"></param>  ///<param name="eventArgs" type="Infragistics.Web.UI.EventArgs"></param>   

  if (document.readyState == "complete") {

        var item0 = sender.get_items().getItem(0);       

        item0.unselect();    

        item0.get_element().childNodes[0].checked = false;     } }

I hope this helps.
