Inserting barcode in crystalreports for Asp.net
We are having a Asp.net website developed in Visual studio 2010. we are using crystal reports for report generation. we need to insert linear barcode in the report.
We have a solution for a similar requirement in Windows application developed in vb.net. we are using .net component barcode generator to insert the barcode in the crystal reports.
Is there any similar component available for asp.net ( open source component would be better)
OR
is there any better solution

wouldn't it be simpler just to use a barcode font?

In my experience, an ASPX script worked best in ASP.NET.
The question is how is the report going to be used / viewed?
IF you're exporting it or printing it . . . you might get away with the font as Eric suggested. If you want to view / use the report interactively online you may need additional coding via your bar code generator.

If you want to show the report exported (i.e. a PDF generated on-the-fly) I'd recommend the use of a barcode font, too. Simple, easy, convenient.
If the barcode is to be viewed online (i.e. after exporting it as html), you could probably generate the barcode as image prior to the report generation and transfer it to the report as blob (i.e. with a subreport that gets the blob within an ADO.NET dataset).
I've not tried that before, but I presume it's possible to "print text" into an image with on-board means of whateverlanguage.NET, so you could use the barcode font to "print" the code into an image and shove it into the report via dataset.
P.S.: I've just done an internet serach on ".NET print text into image" and got 1E6++ hits. Some write over an existing image (i.e. a photograph) but creating an imge full of white background prior to painting black barcode over it seems not that complicated to me ...
