Change datanavigateurlformatstring of hyperlinkfield at runtime

hi,

How do i change the DataNavigateUrlFormatString of the given code below to "http://abcde.com/index.jsp?ID=2&question={0} at run time.

the ID is not coming from database, its based on the query string,
ex if lang = EN then ID = 1
if lang = ES then ID = 2

I have hidden field in my code which holds the ID based on the query string and i tried adding the refrence to the the datanavigateurlformatstring with no luck

DataNavigateUrlFormatString = "http://abcde.com/index.jsp?ID='<%=ID.ClientID%>'&question={0}"

Please suggest any alternate suggestion.

Thanks

<asp:GridView ID="Answer" runat="server" ShowHeader="False" ">
                    <Columns>
                        <asp:HyperLinkfield DataNavigateUrlFormatString = "http://abcde.com/index.jsp?ID=1&question={0}"
                        DataTextField="IRAnswer"   DataNavigateUrlFields = "Answer"  Target = "_blank" Text = "Click Here" />
                        </Columns>
</asp:Gridview>

Hi,

The HyperLinkField does not have the ID property, hence You cannot directly reference it from code behind. However, simply convert the HyperLinkField to a template field and You can reference it from code behind.

Markup:
 
<asp:TemplateField>
    <ItemTemplate>
        <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Answer", "http://abcde.com/index.jsp?question={0}")%>' Text="Answer">
        </asp:HyperLink>
    </ItemTemplate>
</asp:TemplateField>
 
Code behind:
 
    Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim ID As Integer = 0
            If Not String.IsNullOrEmpty(Request("lang")) Then
                If Request("lang") = "EN" Then
                    ID = 1
                ElseIf Request("lang") = "ES" Then
                    ID = 2
                End If
            End If
            Dim hl As HyperLink = CType(e.Row.FindControl("HyperLink1"), HyperLink)
            hl.NavigateUrl = hl.NavigateUrl.ToString + "&ID=" & ID
        End If
    End Sub
