You have a list view on .aspx page for example:

HTML

<asp:listview id="lstEmployee" runat="server" xmlns:asp="#unknown">
            onitemdatabound="lstEmployee_ItemDataBound" >   
   <itemtemplate>
     <tr id="Tr1" runat="server">
      <td id="Td1" runat="server">
        <%-- Data-bound content. --%>
        <asp:label id="NameLabel" runat="server">
          Text='<%#Eval("Name") %>' />
      </asp:label></td>
    </tr>
   </itemtemplate>
   </asp:listview>

and code behind on page load bind list view and on DataBound event get id of label

C#

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

namespace WebApplication1
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            List<employee> empSource = new List<employee>()
                                        {
                                            new Employee()
                                            {
                                                Name ="Sandeep"
                                            },
                                            new Employee()
                                            {
                                                Name ="Raviender"
                                            }
                                        };
            lstEmployee.DataSource = empSource;
            lstEmployee.DataBind();
        }

        protected void lstEmployee_ItemDataBound(object sender, ListViewItemEventArgs e)
        {
            if (e.Item.ItemType == ListViewItemType.DataItem)
            {
                Label lblName = (Label)e.Item.FindControl("NameLabel");
                if (lblName.Text == "Sandeep")
                {
                    lblName.Text = "Sandeep Singh Shekhawat";
                }
            }
        }        
    }
    public class Employee
    {
        public string Name { get; set; }
    }
   
}</employee></employee>

Solution 1

Try like this..

C#

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
       {
           if (e.Item.ItemType == ListViewItemType.DataItem)
           {
              Label lbl =  e.Item.FindControl("yourLabelName") as Label;
              lbl.Text = "Something";
           }
       }
