I just did a test with a repeater to satisfy my own curiosity about your post.  I couldn't find a direct way to do it in the markup (which i was hoping I could) but I was able to get something to work in the code-behind.

Private Sub rptRepeater_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptRepeater.ItemDataBound
    If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
        Dim objDDL As DropDownList = CType(e.Item.FindControl("ddlList"), DropDownList)
        objDDL.SelectedIndex = objDDL.Items.IndexOf(objDDL.Items.FindByValue(e.It em.DataItem.ToString))
    End If
End Sub

e.Item.DataItem is the key.  That will give you the object of the bind, in your case it should give you the current item of the collection.  I'm making the assumption that you want to pre-select something in a dropdownlist based on the value of a property of your collection item.  My test only used an array list of integers so I could do a straight "tostring" on it without error.  You'll need to convert it to the appropriate object type before you do can access the desired property for the DDL preselect value.

Work smarter, not harder.
hi peter, i am having the same problem like izarkhin,and i used the above code to set the dropdown value. everything is fine, but after postback i am still getting the previous record instead of a new record.

Hi There
I have a problem who looks like this one.
I have a repeater with a dropdownlist in it. Data from repeater and dropdownlist come from different datasets.
If I display the number of records in my dropdownlist it gives me the number that I should see in the dropdownlist. But I see blank data in my dropdownlist
Here is my code
what I am missing?
Thank you

ok here is the code in the aspx.vb page

StrsqlEtab = "SELECT NO_ETAB FROM T_ETABLISSEMENT" ' WHERE No_ETAB = '" & Session("No_Etab") & "' ORDER BY NO_POSTE_B_1"

cmdEtab = New SqlCommand(StrsqlEtab, Conn)myDAEtab = New SqlDataAdapter(cmdEtab) 


Bud_1.DataSource = DsEtab


Bud_1.DataTextField = "NO_ETAB"

Bud_1.SelectedIndex = 1

Response.Write(Bud_1.Items.Count)  //this display the number of records that I have in my table T_ETABLISSEMENT


Here is the code in html

<asp:Repeater id="RepeaterAjoutPanier" runat="server">
  <table align=center width=90% bgcolor="#FAFAFA"> 
     <table align=center width=100% >     
      <tr class="Texte13N" bgcolor="#F5F5F5">
       <td align="center" valign="middle"><br> <b>
        <asp:DropDownList runat="server" ID="Bud_1" DataTextField="NO_ETAB" DataValueField="NO_ETAB" AutoPostBack="true" Width="10%" />-

Don't you have to define the datatextfield before the bind?

Any other idea?
