ASP.net AJAX Dropdown and Modal PopUp

I want to have a modal popup display when an option is chosen from a dropdown in ASP.net 4 VB. I know how to make the dropdown and I know how to make the modal popup extender, but I don't know how to tie the 2 together.
Here is the dropdown:

Code:

---

<!-- Add to Product -->
    <asp:Label ID="lblText" runat="server" Text="Add to Product" Width="150px"></asp:Label>
    <asp:Panel ID="DropPanel" runat="server" CssClass="ContextMenuPanel" Style="display:none; visibility:hidden; margin-left:2px;"> 
        <asp:LinkButton ID="Company" runat="server" Text="Company" CssClass="ContextMenuItem" OnClick="OnSelect"></asp:LinkButton>
    <asp:DropDownExtender ID="DropDownExtender1" runat="server" TargetControlID="lblText" DropDownControlID="DropPanel">
    </asp:DropDownExtender>

---

And the modalpopupextender to add the company to the database

Code:

---

<!-- Add a Company -->
<asp:LinkButton ID="LinkButton1" runat="server">Company</asp:LinkButton>
    <asp:Panel ID="Panel1" runat="server" CssClass="modalPopup" Style="display:none">
        <asp:CheckBoxList ID="cbxAddCompany" runat="server" DataSourceID="dsNewCompanies" DataTextField="CompanyName" DataValueField="CompanyID">
        </asp:CheckBoxList>
<asp:Button ID="SubmitCompanies" runat="server" Text="Submit" /><asp:Button ID="CancelSubmitCompanies"
    runat="server" Text="Cancel" />
    </asp:Panel>
    <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="LinkButton1" PopupControlID="Panel1" BackgroundCssClass="modalBackground" DropShadow="true" OkControlID="SubmitCompanies" CancelControlID="CancelSubmitCompanies">
    </asp:ModalPopupExtender>

---

VB:

Code:

---

Protected Sub SubmitCompanies_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SubmitCompanies.Click
        Dim SqlConnection As New SqlConnection("Server=off-db1;uid=productsDB_admin;pwd=@cc3ssproductsdb;database=Products")
        For Each company As ListItem In cbxAddCompany.Items
            If company.Selected Then
                SqlConnection.Open()
                Dim sqlAddCompany As String = "INSERT INTO CompanyLink (ProductID, CompanyID) VALUES (" & ProductID.Value & ", " & company.Value & ")"
                Dim sqlCommand As New SqlCommand(sqlAddCompany, SqlConnection)
                sqlCommand.ExecuteNonQuery()
                SqlConnection.Close()
            End If
        Next
        Response.Redirect(Request.RawUrl)
    End Sub

hi,

you can do that. based on dropdown selection if you want to show the different modalpopup you can show like below in dropdown_selectedindexchanged event

ModalPopupExtender1.Show();

but dont set TargetControlID as button for ModalPopupExtender instead of button set label and set label.text="";

based on if condition you can display the respective ModalPopupExtender in dropdown_selectedindexchanged event
