In this article I will explain how to make populate and bind NavigateUrl property of HyperLink inside ASP.Net GridView ItemTemplate of TemplateField.

HTML Markup
The below HTML Markup consists of an ASP.Net GridView with 4 columns. The first and fourth column have HyperLinks inside the ItemTemplate of TemplateField.
<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 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 runat="server" NavigateUrl='<%# string.Format("~/Details.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>
 
NavigateUrl with Single QueryString Parameter
NavigateUrl='<%# Eval("Id", "~/Details.aspx?Id={0}") %>'
 
The first column HyperLink passes only one QueryString Parameter and hence the same has been set using the Eval function.
 
NavigateUrl with Multiple QueryString Parameters
NavigateUrl='<%# string.Format("~/Details.aspx?Id={0}&Name={1}&Country={2}",
HttpUtility.UrlEncode(Eval("Id").ToString()), HttpUtility.UrlEncode(Eval("Name").ToString()), HttpUtility.UrlEncode(Eval("Country").ToString())) %>'
 
Here we need to pass three QueryString parameters, thus we need to concatenate the Eval functions of the three fields using String Format function.
 
 
Binding the GridView
I have made use of DataTable with some dummy values for this article.
Namespaces
using System.Data;
 
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();
    }
}
 
Bind (Single or Multiple) QueryString Parameters to NavigateUrl of HyperLink using Eval function inside ASP.Net GridView
 
Accessing and displaying the QueryString Values on destination page
On the destination page I am extracting the QueryString values from the URL and displaying them on page.
HTML Markup
<table>
    <tr>
        <td>
            <b>Id</b>
        </td>
        <td>
            <asp:Label ID="lblId" runat="server"></asp:Label>
        </td>
    </tr>
    <tr>
        <td>
            <b>Name</b>
        </td>
        <td>
            <asp:Label ID="lblName" runat="server"></asp:Label>
        </td>
    </tr>
        <tr>
        <td>
            <b>Country</b>
        </td>
        <td>
            <asp:Label ID="lblCountry" runat="server"></asp:Label>
        </td>
    </tr>
</table>
 
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        lblId.Text = HttpUtility.UrlDecode(Request.QueryString["Id"]);
        lblName.Text = HttpUtility.UrlDecode(Request.QueryString["Name"]);
        lblCountry.Text = HttpUtility.UrlDecode(Request.QueryString["Country"]);
    }
}
 
VB.Net
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim dt As New DataTable()
        dt.Columns.AddRange(New DataColumn(2) {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()
    End If
End Sub
