I have created a usercontrol on my site this usercontrol consists of 4 dropdownlists.  The 1st dropdrownlist when selected populates the 2nd dropdownlist (see below for an extract of the ascx file and the ascx.vb)

<div id="returnMarque" class="body">
        <asp:Label Width="50px" ID="lblMarque" runat="server" Text="Marque:"></asp:Label>
        <asp:DropDownList CssClass="body" ID="ddlMarque" runat="server" DataSourceID="MarqueDataSource" DataTextField="MarqueName" DataValueField="MarqueID" AutoPostBack="true"  >
        <asp:SqlDataSource ID="MarqueDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:WestsRenaultConnection %>"
            SelectCommand="GetAllMarques" SelectCommandType="StoredProcedure"></asp:SqlDataSource>

Protected Sub ddlMarque_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlMarque.SelectedIndexChanged
    End Sub

    Private Sub FillModel()
        ddlModel.DataSource = GetModels(Integer.Parse(ddlMarque.SelectedValue))
        ddlModel.DataTextField = "ModelName"
        ddlModel.DataValueField = "ModelName"
    End Sub

This all works fine but when I plug it into my main page when I select from the 1st dropdownlist it loads a PDF file. (There is reference to the PDF file in code when a user clicks a link).

Have you got any ideas as to why this may be happening and how this issue can be resolved.

Many Thanks
