    Hi ChetanRajakumar,

     

    Please try the example below. In the example below, I check the file name which with string 'a', and add it for the datalist control. You can use the same code to check the file name from your database.

     

    1. <%@ Page Language="C#" AutoEventWireup="True" %>  
    2.   
    3. <%@ Register TagPrefix="CuteWebUI" Namespace="CuteWebUI" Assembly="CuteWebUI.AjaxUploader" %>  
    4. <%@ Import Namespace="System.Data" %>

    10.     {  
    11.         DataTable dt = new DataTable();  
    12.         DataRow dr;  
    13.         dt.Columns.Add(new DataColumn("FileName", typeof(String)));  
    14.         for (int i = 0; i < files.Count; i++)  
    15.         {  
    16.             dr = dt.NewRow();  
    17.             dr[0] = files[i].ToString();  
    18.             dt.Rows.Add(dr);  
    19.         }  
    20.         DataView dv = new DataView(dt);  
    21.         return dv;  
    22.     }

    30.             if (args[i].FileName.IndexOf("a") != -1)  
    31.             {

    40.         ItemsList.DataBind();  
    41.     }  
    42.   
    43.
