Search.ascx.cs C# Code:

1. Now Open the Code behind file of Friends User Control. In Search.ascx.cs file you can add the following piece of code given below.
2. In the Search.ascx user control code behind from the page load method we are calling GetSearchResults() to get the search results.
3. what ever the user have entered to search we are storing it in session and based on the session we are search the results.
4. We have made use of sql like operator to get the results which begins with the search text

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;

public partial class Controls_Search : System.Web.UI.UserControl
{
    protected void Page_Load(object sender, EventArgs e)
    {
        GetSearchResults();
    }

    private void GetSearchResults()
    {
        DataTable dt = new DataTable();
        string query = "Select * FROM [Register] 
        where Name like '" + Session["SearchText"].ToString() + "%'";
        dt = Database.GetData(query);
        if (dt.Rows.Count > 0)
        {

            SearchList.Visible = true;
            SearchList.DataSource = dt;
            SearchList.DataBind();
        }
        else
        {

        }
    }

    protected void imgbtnPic_Click(object sender, ImageClickEventArgs e)
    {
        Session["CurrentProfileId"] = (((ImageButton)sender).CommandArgument).ToString();
        Response.Redirect("Main.aspx");
    }
}
