I am not getting updated pageindex when navigating from page to page. it shows previous page number, not current one which is clicked.
Master.SearchResults is radGrid


Following is configuration of grid on aspx.
    <telerik:RadGrid ID="SearchResultsGrid" runat="server" EnableViewState="True"
            Height="100%" AutoGenerateColumns="false" AllowPaging="true" AllowCustomPaging="true"
            AllowSorting="True" AllowMultiRowSelection="True" GridLines="None" 
            Skin="Telerik"  OnItemCommand="SearchResultsGrid_ItemCommand"
            OnNeedDataSource="SearchResultsGrid_NeedDataSource" PageSize="50" Width="721" >
            <MasterTableView EnableNoRecordsTemplate="true" TableLayout="Fixed" DataKeyNames="AssignmentId">









protected void SearchResultsGridNeedDataSource(object source, GridNeedDataSourceEventArgs e)
        {
            try
            {
                    LoadSearchResults();
            }
            catch (Exception ex)
            {
                HandleException(Master.ErrorMessagePanel, AssignmentErrorMessages.FIND_ASSIGNMENTS, string.Empty, MessageStatus.Error, ex);
            }
        }

 private void LoadSearchResults(bool dataBind = false)
        {
            if (rdoObjectType.SelectedItem == null)
            {
                return;
            }
            if (string.IsNullOrEmpty(selNames.SelectedValue))
            {
                return;
            }
            int objectId = int.Parse(rdoObjectType.SelectedItem.Value);
            int nameId = int.Parse(selNames.SelectedValue);
            List<SelectListDto> clientNames = (List<SelectListDto>)GetClientNames(objectId, selNames.Text);
            int objectTypeId = int.Parse(clientNames.Single(c => c.Value == int.Parse(selNames.SelectedValue)).ExtraField);
            int statusId = int.Parse(rdoStatus.SelectedValue);
            AssignmentSearchResultDto assignments  = FindAssignment(objectTypeId, objectId, nameId, statusId);
 
            Master.SearchResults.VirtualItemCount = assignments.TotalItems;
            Master.SearchResults.AllowCustomPaging = true;
            Master.SearchResults.DataSource = assignments.Assignments;
            Master.SearchResults.PageIndexChanged += RadGrid1_PageIndexChanged;
        }

 private AssignmentSearchResultDto FindAssignment(int objectTypeId, int objectId, int personId, int status)
        {
            int startRowIndex = Master.SearchResults.CurrentPageIndex * Master.SearchResults.PageSize;
            int maximumRows = Master.SearchResults.PageSize;
            AssignmentSearchResultDto assignments;
            using (Assignment assignment = new Assignment())
            {
                assignments = assignment.FindAssignment(objectTypeId, objectId, personId, status, agencyId, startRowIndex, maximumRows);
            }
            return assignments;
        }
