After installation, I am going to generate a query to retrieve the Isactive values from the news list.

retrieve the Isactive values

Code
  1. using Microsoft.SharePoint;  
  2. using System;  
  3. using System.ComponentModel;  
  4. using System.Web.UI.WebControls.WebParts;  
  5.   
  6. namespace News.News_Rollup  
  7. {  
  8.     [ToolboxItemAttribute(false)]  
  9.     public partial class News_Rollup : WebPart  
  10.     {  
  11.         // Uncomment the following SecurityPermission attribute only when doing Performance Profiling on a farm solution  
  12.         // using the Instrumentation method, and then remove the SecurityPermission attribute when the code is ready  
  13.         // for production. Because the SecurityPermission attribute bypasses the security check for callers of  
  14.         // your constructor, it's not recommended for production purposes.  
  15.         // [System.Security.Permissions.SecurityPermission(System.Security.Permissions.SecurityAction.Assert, UnmanagedCode = true)]  
  16.         public News_Rollup()  
  17.         {  
  18.         }  
  19.   
  20.         protected override void OnInit(EventArgs e)  
  21.         {  
  22.             base.OnInit(e);  
  23.             InitializeControl();  
  24.         }  
  25.   
  26.         protected void Page_Load(object sender, EventArgs e)  
  27.         {  
  28.             if(!Page.IsPostBack)  
  29.             {  
  30.                 Bindspeaker();  
  31.             }  
  32.         }  
  33.         private void Bindspeaker()  
  34.         {  
  35.             using (SPSite site = new SPSite(SPContext.Current.Site.Url))  
  36.             {  
  37.                 using (SPWeb web = site.OpenWeb())  
  38.                 {  
  39.                     SPList list = web.Lists["News"];  
  40.                     if (list != null)  
  41.                     {  
  42.                         SPQuery query = new SPQuery();  
  43.                         query.Query = "<Where><Eq><FieldRef Name='Isactive' /><Value Type='Boolean'>1</Value></Eq></Where>";  
  44.                         SPListItemCollection collitem = list.GetItems(query);  
  45.   
  46.                         rptsmartspeak.DataSource = collitem.GetDataTable();  
  47.                         rptsmartspeak.DataBind();  
  48.   
  49.                     }  
  50.                 }  
  51.             }  
  52.         }  
  53.     }  
  54. }  
Now I am going to do some customization of my repeater control to view the news stylish.
