Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [products]" GridView1.DataKeyNames = "pid" Dim lnk As HyperLinkField lnk = New HyperLinkField lnk.DataTextField = "pname" lnk.NavigateUrl = "home.aspx" lnk.DataNavigateUrlFields = "pid" End Sub<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" EnableViewState="false"> -

I didn't get any requirements for the signature

Dim x As String() = New String(0) {} x(0) = "pid" lnk.DataNavigateUrlFields = x(0)

thank you so much for taking the time to answer, but still not working, i can't believe, i put the code this way
Dim lnk As HyperLinkField lnk = New HyperLinkField lnk.DataTextField = "pname" lnk.NavigateUrl = "home.aspx" lnk.DataNavigateUrlFormatString = "~/home.aspx?pid={0}" Dim x As String() = New String(0) {} x(0) = "pid" lnk.DataNavigateUrlFields = x(0)and still, over the last line on x(0) still have the message that says value of type 'string'cannot be converted to '1 dimensional array of string' -

i mean if i coment this line
lnk.DataNavigateUrlFields = x(0)it add that hyperlinkfield , but not passing the parameter.lnk.DataNavigateUrlFields = x BTW, set option strction on set option explicit on It will force you to write better code.
