Hi,
My current project is a real estate website. In this I have to display the details of the properties in small boxes. I did it successfully using data list in rows and columns. But I want to enable paging in data list. I searched in Google and got many codes. But none of that satisfied my requirement.

Here is my .aspx code

<table>
<tr>
    <td>
<asp:DataList ID="DataList1" runat="server" DataKeyField="fldId" 
        DataSourceID="SqlDataSource1" RepeatColumns="2" OnSelectedIndexChanged="dlProducts_SelectedIndexChanged">
        <ItemTemplate>
            <asp:Image ID="Image1" runat="server" Height="111px" 
                ImageUrl='<%# Eval("fldImage", "~/Property/{0}") %>' Width="247px" />           
.
.
.


        </ItemTemplate>
    </asp:DataList>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
        SelectCommand="SELECT [fldId], [fldImage], [fldCategory] FROM [tblMaster]">
        <SelectParameters>
            <asp:Parameter DefaultValue="1" Name="fldAd" Type="String" />
        </SelectParameters>
    </asp:SqlDataSource>
</td></tr?
<tr>
            <td>
                <asp:Label ID="lblCurrentPage" runat="server" Visible="true"></asp:Label>
            </td>
        </tr>

        <tr>
            <td align="center">
                <asp:Button ID="cmdPrev" runat="server" Text=" << " OnClick="cmdPrev_Click" />
                <asp:Button ID="cmdNext" runat="server" Text=" >> " OnClick="cmdNext_Click" />

            </td>
        </tr>
        </table>

I tried this .aspx.cs code, but got the error
"

The name 'CurrentPage' does not exist in the current context.

"

.aspx.cs

protected void items()
  {
      PagedDataSource objDs = new PagedDataSource();
      DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);
      objDs.DataSource = dv;
      objDs.AllowPaging = true;
      objDs.PageSize = 5;
      objDs.CurrentPageIndex = CurrentPage;
      lblCurrentPage.Text = "Page:" + (CurrentPage + 1).ToString() + " Of " + objDs.PageCount.ToString();
      cmdPrev.Enabled = !objDs.IsFirstPage;
      cmdNext.Enabled = !objDs.IsLastPage;
      DataList1.DataSource = objDs;
      DataList1.DataBind();

  }


  protected void cmdPrev_Click(object sender, EventArgs e)
  {
      try
      {
          CurrentPage -= 1;
          items();
      }
      catch (Exception ex)
      {
          Logger.LogException(ex);
      }
  }

  protected void cmdNext_Click(object sender, EventArgs e)
  {
      try
      {

          CurrentPage += 1;
          items();
      }
      catch (Exception ex)
      {
          Logger.LogException(ex);
      }
  }

How can I remove this error or is there any other methods to apply paging in Datalist? Please give me any ideas to overcome my problem.
Thank you...
