Repeater and unipager

Sorry, i added the whole source code but the it takes only few lines for the question.

The server side code to bind the repeater with dataset.

        string customTableClassName = "ct.OrganisationsAndVenues";

        DataClassInfo customTable = DataClassInfoProvider.GetDataClassInfo(customTableClassName);
        if (customTable != null)
        {
            DataSet customTableItems = CustomTableItemProvider.GetItems(customTableClassName);
            if (!DataHelper.DataSourceIsEmpty(customTableItems))
            {
                rptOrganisationInfo.DataSource = customTableItems;
                rptOrganisationInfo.DataBind();
            }
        }

This is my code. I am trying to display custom table items with paging option. the code display the custom table records but not the paging. the paging does not appear.
