HTML

<asp:GridView ID="GridView1" HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White"
    RowStyle-BackColor="#A1DCF2" AlternatingRowStyle-BackColor="White" AlternatingRowStyle-ForeColor="#000"
    runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:TemplateField HeaderText="Id" ItemStyle-Width="30">
            <ItemTemplate>
                <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Id", "~/Details.aspx?Id={0}") %>'
                    Text='<%# Eval("Id") %>' />
            </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
        <asp:BoundField DataField="Country" HeaderText="Country" ItemStyle-Width="150" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:HyperLink ID="HyperLink2" runat="server" Target="_self" NavigateUrl='<%# string.Format("javascript: DynamicDataEncryption(\"VAAddEditMicroscopic.aspx?ID={0}&Name={1}&Country={2}\")",
                HttpUtility.UrlEncode(Eval("Id").ToString()), HttpUtility.UrlEncode(Eval("Name").ToString()), HttpUtility.UrlEncode(Eval("Country").ToString())) %>'
                    Text="View Details" />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Namespace

using System.Data;

C#

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id"), new DataColumn("Name"), new DataColumn("Country") });
        dt.Rows.Add(1, "John Hammond", "United States");
        dt.Rows.Add(2, "Mudassar Khan", "India");
        dt.Rows.Add(3, "Suzanne Mathews", "France");
        dt.Rows.Add(4, "Robert Schidner", "Russia");
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
}

JavaScript

<script type="text/javascript">
    function DynamicDataEncryption(value) {           
        alert(value);
    }        
</script>
