ClientReport Reset

edited September 2002 in Server
Running with a RB server accessing it via Delphi EXE using rsClientReport
and DADE - I can't get the report to reset after it's been viewed once.

This seems like a common issue throughout the newsgroups and the suggested
solutions don't seem to work. Report.Reset and Viewer.Reset have no effect.

Thanks in advance! Jon Gray

    Try
    report.CloseDataPipelines

    That seems to work for me.

    Thanks for the reply but I can't seem to find "CloseDataPipelines"
    associated with a report?

    I see CloseDataSource but it too isn't valid for the rsClientReport.

    Am I in the wrong spot altogether?

    There are differences between Report and ClientReport though they do
    share a common ancestory and have many similarities as well. Therefore
    answers you see in other newsgroup may not apply.

    Try the following:

    ClientReport.RefreshRequest := True;
    ClientReport.Print;

    This didn't work for me. The Autosearch is not displayed again. Everything
    still kinda works, but the report is not respecting new autosearch values I
    stuff in for example.

    Sorry I did not understand what you are trying to do. Perhaps my reply
    to the thread above this one is applicable. If not then I will need more
    details....

    I'm sure I wasn't clear...

    I'm looking for a way to completely "reset" a TrsClientReport so it behaves
    exactly like it does the first time it's loaded and executed. So the
    AutoSearch Dialog fires normally and the query data is refreshed.

    I researched this and put together a simple example that I think
    satisifies your requirements. I modified the
    RBServer\Demos\Client\ClientReport example as shown below. It probably
    should be a little simpler than this, but the ClientReport is optimized
    to cache pages and to cache autosearch information and the Server does
    the same. There are situations in which you want to flush one cache but
    not the other.



    procedure TfrmClientReport.btnPrintClick(Sender: TObject);
    begin

    {specify the report to execute}
    rsClientReport1.VolumeName := 'Report Forms';
    rsClientReport1.ReportName := 'AutoSearch\Biolife Table';

    {if re-running the same report, this tells the server to destroy the
    existing
    report instance and create a new one.}
    rsClientReport1.RefreshRequest := True;

    {if re-running the same report, this tells the client report to flush
    its
    local cache and request the report pages from the server.}
    rsClientReport1.Reset;

    {if re-running the same report, this tells the client report to clear
    existing
    autosearch information}
    rsClientReport1.AutoSearchGroups.Clear;

    rsClientReport1.Print;

    end;

    procedure
    TfrmClientReport.rsClientReport1ReceiveAutoSearchFields(Sender:
    TObject);
    begin

    {set the search values that have been received from the server}
    SetAutoSearchValues;

    {suppress the autosearch dialog and send the search values to the
    server}
    rsClientReport1.ShowAutoSearchDialog := False;
    rsClientReport1.PrintToDevices;

    end;


    procedure TfrmClientReport.SetAutoSearchValues;
    begin

    if (rsClientReport1.AutoSearchFieldCount > 0) then
    begin

    FCount := FCount + 1;

    {this code simply toggles the search value from S to C}
    if (FCount Mod 2 = 0) then
    rsClientReport1.AutoSearchFields[0].SearchExpression := 'S'
    else
    rsClientReport1.AutoSearchFields[0].SearchExpression := 'C';

    rsClientReport1.AutoSearchFields[0].ShowAllValues := False;

    end;


    end;
