How to perform text search on TppViewer?

rbuser

Hi,

The default ReportBuilder preview form has text search function that
able to search the text in report.

I am using TppViewer to show the report. How to utilize the text search
function for TppViewer?

Hi Chau Chee,

You can manually create a TppTextSearchPreview object and assign its
Viewer property. It also needs a panel to reside in. Below is some
sample code.

lTextSearchPreview := TppTextSearchPreview.Create(self);

lTextSearchPreview.Viewer := ppViewer1;
lTextSearchPreview.TextSearchSettings.Visible := True;
lTextSearchPreview.TextSearchSettings.Enabled := True;
lTextSearchPreview.CreateControls(Panel1);
lTextSearchPreview.ArrangeControlsVertically;
lTextSearchPreview.BeforePreview;

Hi NG,

I just realized that if I have a 200 page report and the default setting
is only calculating 100 pages ahead and I search for a common word that
appears on each page of the report and I click the "last occurance"
symbol in the TTextSearchPreivew it will go the last occurance on page
100 although more occurances will follow.
I guess it is linked to the number of pages you calculate in advance.
But I think RB should at that moment calculate the rest of the report
before performaning the actual search.
Do you agree?

Hi Stephan,

You are correct. We will try to get this added into the next release of
ReportBuilder.

Hi,

When testing the search function I found that the function automatically
changes the page to the one where the "active" search result is located.
That's good.

However if the user views the page with a high zoom level, then ppViewer
does not scroll automatically to the location of the search result on
the page. Is it possible to implement this feature somehow?
I have already checked the RB source code, but all information of the
search engine seem to be stored in private methods and properties and
therefore are not utilizable.

Hi David,

Which version of ReportBuilder are you using? For versions earlier than
14, ReportBuilder does try to navigate to the location on the page that
the text resides. For RB 14 with the new previewer, this feature is not
yet implemented however you can set the
PreviewFormSettings.SinglePageOnly property to True to revert back to
the older viewer which supports this feature.

I have added this as an enhancement to research and implement for a
later release and will keep you up to date as progress is made.

Nico,

don't you think that your customers updating from version 12 to 14 will
miss this feature? I would call it a bug if that was the fact before and
is gone in the new release even if there is a flag to get back to the
old functionaly again. THe reason we purchased the new release are the
new features.
Please rethink your decision to not implement it immediately.

Thanks for the ongoing support,

Stephan

I apologize for the misunderstanding. By "later release" I meant an
upcoming maintenance release (hopefully 14.05).

The new viewer/preview was a complete re-write from the old one. We
worked diligently to include all the features of the old viewer however
some either could not, or did not yet make it in. We will continue to
enhance the new viewer to include as much as we can however being that
it was a complete re-design/re-write, providing a simple patch is
usually not immediately possible.

Thanks for your patience and support.

Nico,

thanks for the clarification.
We will patiently wait for 14.05 then.
I fully appreciate the work you have put into the redesign for Version 14!

Thanks,

Stephan
