Item doesnot exist in current context.

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="Description" HeaderText="Description" />
