Creating a report from a TTreeView

rbuser

I need to print a report from a TTreeView. Presently I save the TreeView to
a text file and print it from there, but I want a more professional Report.
Actually the output suits my clients needs to the tree structure is just
fine.

What is a simple method to pass a TreeView to ReportBuilder to create a
basic multi-level report following the tree structure?

Hi Larry,

One way you could try would be to traverse your tree structure ahead of time
and build an index of the nodes to be printed. You can assign each node a
unique id and place them in a TStringList object. Then using a JITPipeline,
you can pull the data directly out of the string list and display it in your
report.

The article below show how to create a simple index.

Question
--------

I am using JITpipeline and I want to know is there a way
to sort the data?


Solution
--------

You can implement this functionality by creating an
index for your data.


A simple index can be made using a StringList. You can
iterate through your data and for each row add an entry
to the stringlist. Each entry will contain the string
value to sort and the row index.

myIndex := TStringList.Create;

for liRow := 0 to RowCount-1 do
myIndex.AddObject(StringValueToSort, TObject(liRow));



Once you load the data, then you can sort the StringList:

myIndex.Sort;


Now you have an index in which each item in
the stringlist contains a pointer to the correct row.

To get the data for the first row:

liRowIndex := Integer(myIndex.Object[0]);

Larry,

please have a look at our TreeView for ReportBuilder component at
www.choosepill.com/components/cpcrbtree.htm . It's exactly designed for this
purpose and allows you to print a complete TTreeView with images, buttons
and lines. You can also use this component to print a simple text
representation of the tree.

However, this component is only available for ReportBuilder 6.x and 7.x!

Hope this helps

Thanks to both of you. I will need to go with the StringList. My client
has no interest in upgrading to RP 6 at this time.
