Item doesnot exist in current context.

Question

Hi.

 

I have the following code.

private void GetItemsPageWise(int pageIndex)
       {
           string conString = ConfigurationManager.ConnectionStrings["FileStoreEntities"].ConnectionString;
           using (SqlConnection con = new SqlConnection(conString))
           {
               using (SqlCommand cmd = new SqlCommand("GetItems", con))
               {
                   cmd.CommandType = CommandType.StoredProcedure;
                   cmd.Parameters.AddWithValue("@PageIndex", pageIndex);
                   cmd.Parameters.AddWithValue("@PageSize", int.Parse(itemddlPageSize.SelectedValue));
                   cmd.Parameters.Add("@RecordCount", SqlDbType.Int, 4);
                   cmd.Parameters["@RecordCount"].Direction = ParameterDirection.Output;
                   con.Open();
                   IDataReader idr = cmd.ExecuteReader();
                   ItemView.DataSource = idr;
                   ItemView.DataBind();
                   idr.Close();
                   con.Close();
                   int recordCount = Convert.ToInt32(cmd.Parameters["@RecordCount"].Value);
                   this.PopulatePager(recordCount, pageIndex);
               }
           }
       }

 and the aspx as -

 

<form id="form1" runat="server">
    <div>
        PageSize:
        <asp:DropDownList ID="itemddlPageSize" runat="server" AutoPostBack="true" OnSelectedIndexChanged="PageSize_Changed">
            <asp:ListItem Text="10" Value="10" />
            <asp:ListItem Text="25" Value="25" />
            <asp:ListItem Text="50" Value="50" />
        </asp:DropDownList>
        <hr />
        <asp:GridView ID="ItemView" runat="server" AutoGenerateColumns="False">
            <Columns>
                <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" />
                <asp:BoundField DataField="Name" HeaderText="Name" />
                <asp:BoundField DataField="Cost" HeaderText="Cost" />
                <asp:BoundField DataField="Image" HeaderText="Image" />
                <asp:BoundField DataField="Description" HeaderText="Description" />
                <asp:BoundField DataField="AddedBy" HeaderText="AddedBy" />
            </Columns>
        </asp:GridView>
