Bind HyperLink Control With URL Parameter To GridView In Asp.net Using C#

5/30/2016 - By Pranav Singh 0

This article will show you how you can bind a hyperlink control with url parameter or requestquery string value to gridview in asp.net using c#.net. In this article I have used asp.net hyperlink control to generate a hyper link with parameter inside the TemplateField’s ItemTemplate.

So for this article first I have created an asp.net application and add the below code of gridview which have TemplateField.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm7.aspx.cs" Inherits="WebApplication7.WebForm7" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Bind HyperLink Control To GridView In Asp.net Using C#</title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
                <Columns>
                    <asp:BoundField DataField="CountryName" HeaderText="Country Name" />
                    <asp:BoundField DataField="Population" HeaderText="Population" />
                    <asp:BoundField DataField="Code" HeaderText="Code" />
                    <asp:TemplateField HeaderText="Link">
                        <ItemTemplate>
                            <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Link") %>'>Detail</asp:HyperLink>
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
            </asp:GridView>
        </div>
    </form>
</body>
</html>

In above code inside the ItemTemplate I have added an asp.net hyperlink control. This control’s NavigateUrl I have bind with the link field.  
With the help of edit template we can bind the navigation url of hyperlink.



Now check the code to bind the grid view.
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication7
{
    public partial class WebForm7 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();
            dt = GetCountryData();
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
        private DataTable GetCountryData()
        {
                        DataTable dt = new DataTable();
            dt.Clear();
            dt.Columns.Add("CountryName");
            dt.Columns.Add("Population");
            dt.Columns.Add("Code");
            dt.Columns.Add("Link");

            DataRow dataRow1 = dt.NewRow();
            dataRow1["CountryName"] = "India";
            dataRow1["Population"] = "125 Cr";
            dataRow1["Code"] = "IN";
            dataRow1["Link"] = "http://www.aspdotnet-pools.com?country=India";
            dt.Rows.Add(dataRow1);

            DataRow dataRow2 = dt.NewRow();
            dataRow2["CountryName"] = "Pakistan";
            dataRow2["Population"] = "50 Cr";
            dataRow2["Code"] = "PK";
            dataRow2["Link"] = "http://www.aspdotnet-pools.com?country=Pakistan";
            dt.Rows.Add(dataRow2);

            DataRow dataRow3 = dt.NewRow();
            dataRow3["CountryName"] = "United States";
            dataRow3["Population"] = "25 Cr";
            dataRow3["Code"] = "US";
            dataRow3["Link"] = "http://www.aspdotnet-pools.com?country=United-States";
            dt.Rows.Add(dataRow3);

            return dt;
        }
    }
}

In above code I have added a new column “Link”, which is having the navigation url with parameter to bind with the hyperlink control. Now we have done run the application to check the output.
