Hi

according to below thread I use code in my page

Highlight-text-in-datalist/

and I change my code like below

 protected void HouseP_Click(object sender, EventArgs e)
    {

           string openingTag = "<span style='background-color:Yellow'><b>";
    string closingTag = "</b></span>";


        SqlCommand _cmd = new SqlCommand("AdminSearchP", _cn);
        _cmd.CommandType = CommandType.StoredProcedure;

        _cn.Open();

        SqlDataReader dr = _cmd.ExecuteReader();
        if (dr.HasRows)
        {
             dr[1]= dr[1].ToString().Replace(dr[2].ToString(), openingTag + dr[2].ToString() + closingTag);
          
            DataList1.DataSource = dr;
            DataList1.DataBind();
        }

        _cn.Close();
    }
