Use formula for that line in your report. its so simple... you can write ur code as VB...

Ok... You forced me to install a windows XP in a virtual machine and VS 2008 on it to find this answer... ;)
anyway, this is the answer...
You should write this code where ever u wanna show that report:
First of all add this refrence to your code:

using CrystalDecisions.CrystalReports.Engine;

Then you can access your object (in our case its a LineObject) like so:

ReportDocument reportDoc = CrystalReport11;

//1- define a LineObject variable
LineObject myLine;

//Find the object in ReportObjects collection and cast it as LineObject
//and finally, set it to your variable
myLine = ((LineObject)reportDoc.ReportDefinition.ReportObjects["Line1"]);

//do your changes...
myLine.LineColor = Color.Red;

I've defined a ReportDocument in order to show you how to do it with dynamically loaded reports...
Good luck
