Hi,

I am trying to add a dropdown list to a list view. When I try to use the findcontrol method of the list view to get a handle to the dropdown list it only appears to be searching the item template. I cannot get a handle to the dropdown list in the Edit item template.

Has anyone used a dropdown to edit data using a list view??

Your help will be much appreciated.

<EditItemTemplate>
<td><asp:DropDownList ID="ddl_ProjectStatus"  runat="server" /></td>
</EditItemTemplate>
 
 
 
Private Sub lv_ProjectList_ItemEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewEditEventArgs) Handles lv_ProjectList.ItemEditing
Dim conn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
Dim da As SqlDataAdapter = New SqlDataAdapter("SELECT CodeDetail,Description FROM CodeDetail WHERE DELETED = 0", conn)
        Dim ds As New DataSet
        Dim ddl As DropDownList
 
        ' Get a handle to the ddl_ProjectStatus DropDownList control
        ddl = lv_ProjectList.Items(e.NewEditIndex).FindControl("ddl_ProjectStatus")
 
        'Make sure we have the handle !
        If Not (ddl Is Nothing) Then
            da.Fill(ds)
            ddl.DataSource = ds
            ddl.DataTextField = "Description"
            ddl.DataValueField = "CodeDetail"
            ddl.DataBind()
        End If
    End Sub
