I'm trying to merge 2 fastreport previews result but it's not working as I expected..
Could someone help me to fix this one ?



Example)

var
aStream:TMemoryStream;
begin
aStream := TMemoryStream.create;

TBlobField(Qry.FieldbyName('report_blob')).SaveToStream(aStream);
aStream.position := 0;
frxReport1.PreviewPages.LoadFromStream(aStream);

aStream.clear;
TBlobField(Qry.FieldbyName('report_blob_2')).SaveToStream(aStream);
AStream.position := 0;
frxReport2.PreviewPages.LoadFromStream(aStream);

frxReport1.PreviewPages.AddFrom(frxReport2) //try merge previews.. and I gets "list index out of bounds(-1)" error message

    when merging more then 2 reports : "list index out of bounds(-1)" error

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
