  <asp:Literal ID="lt_image" runat="server"></asp:Literal>
  
  -------------------------------------------------------------
  
  cs file
  private int id;
      private int articalid;
      Cls_Connection conn = new Cls_Connection();
      protected void Page_Load(object sender, EventArgs e)
      {
  
          articalid = int.Parse(Artical_Id.ToString());
          Image_Check(articalid);
  
  
      }
      public int Artical_Id
      {
          get
          {
              return id;
          }
          set
          {
              id = value;
          }
      }
      void Image_Check(int articalId)
      {
          DataTable dt = conn.Blog_details(articalId);
          if (dt != null && dt.Rows.Count > 0)
          {
              DataRow dr = dt.Rows[0];
  
              if (dr["imageurl"].ToString() != null && dr["imageurl"].ToString() != "")
              {
                  lt_image.Text = "<div class='post-img picture'><a href=" + dr["imageurl"].ToString().Remove(0, 2) + " rel='image' title=" + dr["Heading"].ToString() + "><img src=" + dr["imageurl"].ToString().Remove(0, 2) + " alt='' /><div class='image-overlay-zoom'></div></a> </div>";

  public int Artical_Id      {          get          {              return id;          }          set          {              id = value;          }      } 

  Hi,

  Your Article_Id doesn't have a hiddenfield, which means once you submit a page, it will lost its value until next time's data-binding. I suggest you using this:

  public int Artical_Id
      {
          get
          {
              return ViewState["url"]==null?string.Empty:ViewState["url"].ToString();
          }
          set
          {
              return ViewState["url"].ToString();
          }
      }
