ASPxGridView - An error occurs when PageSize is set to zero and the focused row feature is enabled

Hi Ankri,

I was not able to reproduce this behavior.
Attached is the archive with a sample project I used together with a short video demonstrating my steps.

Would you please modify my sample or provide yours?

Thanks,

hello alex,

 We have just find solution:
 it seems that when the property pagesize = 0 and the property AllowFocusedRow = "true" the problem appears!

aspx :
 <dx:LinqServerModeDataSource ID="LinqServerModeDataSource1" runat="server" OnSelecting="lsmds_Selecting"
                DefaultSorting="[DateGC] desc" />
            <dx:ASPxGridView ID="ASPxGridView1" runat="server" Width="100%" KeyFieldName="idcandidat"
                AutoGenerateColumns="false" OnDataBound="ASPxGridView1_DataBound" DataSourceID="LinqServerModeDataSource1">
                <Columns>
                    <dx:GridViewDataTextColumn ShowInCustomizationForm="true" Visible="true" VisibleIndex="21"
                        Name="LibCandidat" FieldName="LibCandidat" Caption="<%$ Resources:LocalizedText, lb_778 %>"
                        Width="300px">
                        <CellStyle HorizontalAlign="Left" Wrap="True">
                        </CellStyle>
                    </dx:GridViewDataTextColumn>
                </Columns>
                <SettingsBehavior EnableRowHotTrack="true" AllowFocusedRow="false" ConfirmDelete="true" />
                <SettingsPager PageSize="0">
                </SettingsPager>
                <Settings ShowFilterBar="Visible" ShowFilterRow="True" />
            </dx:ASPxGridView>

c#
 protected void lsmds_Selecting(object sender, DevExpress.Data.Linq.LinqServerModeDataSourceSelectEventArgs e)
        {

                      dc_CandidatDataContext gDC = new dc_CandidatDataContext(HttpContext.Current.Session["Db_Source"].ToString());

            var query = from v in gDC.V_ListeCandidats_E
                        where (v.idPoste == -1) && ((v.EtatPoste == 0) || (v.EtatPoste == null))
                        select v;

            e.KeyExpression = "idcandidat";
            e.QueryableSource = query;

        }

        protected void ASPxGridView1_DataBound(Object sender, EventArgs e)
        {

            ASPxGridView grid = sender as ASPxGridView;

            if (grid.FilterExpression != "")
                grid.SettingsPager.PageSize = 5;
            else
                grid.SettingsPager.PageSize = 0;
        }

Hi Ankri,

Thank you for the code.
Now I can reproduce the problem.

I passed this bug report to our developers for further research.
We will notify you as soon as the fix is ready.

Thanks,
