This article describes how to change background colour of the whole item of a list view based on the search string



In aspx page three controls has been added.

  • txtSearch used to enter the search string.
  • Button1 used to start search.
  • ListView1 used to show the result set.

// write code here

<asp:TextBox ID="txtSearch" runat="server"></asp:TextBox><asp:Button ID="Button1" runat="server" Text="Search" OnClick="Button1_Click" />

    <asp:ListView ID="ListView1" runat="server" ItemPlaceholderID="itemPlaceholder">


            <table border="0" cellpadding="1">

                <tr style="background-color: #E5E5FE">

                    <th align="left" >

                        <asp:Literal ID="Literal1" runat="server" Text="Name" ></asp:Literal>


                    <th align="left">

                        <asp:Literal ID="Literal2" runat="server" Text="Country" ></asp:Literal>



                <tr id="itemPlaceholder" runat="server">





            <tr runat="server" id="_itemrow">

                <td >

                    <asp:Literal ID="Literal1" runat="server" Text='<%# Eval("Name") %>'></asp:Literal>



                    <asp:Literal ID="Literal2" runat="server" Text='<%# Eval("Country") %>' ></asp:Literal>





C# Code

I am changing the back colour of the row which holds the dataitem when a particular search string is found in a row, it is handled in Itemdatabound event
which is registered in OnLoad.


public partial class TestPage : System.Web.UI.Page


protected override void OnLoad(EventArgs e)



ListView1.ItemDataBound += new EventHandler<ListViewItemEventArgs>(ListView1_ItemDataBound);

if (!IsPostBack)



void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)


if (!string.IsNullOrEmpty(txtSearch.Text) && txtSearch.Text.Trim().Length > 0)


string srch = txtSearch.Text.Trim().ToLower();

var _data = (e.Item as ListViewDataItem).DataItem as Sample;

if ((!string.IsNullOrEmpty(_data.Name) && _data.Name.ToLower().Contains(srch)) || (!string.IsNullOrEmpty(_data.Country) && _data.Country.ToLower().Contains(srch)))


HtmlTableRow abc = e.Item.FindControl("_itemrow") as HtmlTableRow;

abc.BgColor = "Green";




protected void Button1_Click(object sender, EventArgs e)




private void BindListView()


ListView1.DataSource = GetSampleList();



private List<Sample> GetSampleList()


// build a sample collection to bind in list view

List<Sample> lst = new List<Sample>();

lst.Add(new Sample { Country = "India", Name = "Dotnetfunda" });

lst.Add(new Sample { Country = "Usa", Name = "abc def" });

lst.Add(new Sample { Country = "Singapore", Name = "hello z" });

lst.Add(new Sample { Country = "UK", Name = "salman khan" });

return lst;



public class Sample


public string Name { get;set; }

public string Country { get; set; }



Thank you.
